Tiny spider mites, which can only be seen under a microscope, can cause colossal damage any cultivated plants.
Among their gastronomic preferences are eggplants, tomatoes and bell peppers. If they grow in the garden or in the greenhouse, they will be the first to suffer from the invasion of ticks — vegetarians. How to fight with spider mite, what methods to use?
Will consider methods and measures to combat spider mites in greenhouses and on sites. Having found traces of the destructive activity of pests, one should immediately start their extermination. Several methods have been developed that effectively and reliably eliminate tick populations.
Methods And Control Measures
There was a web on cultures: what to do?
It consists in the use of various chemicals.
Against ticks can be used acaricides and insectoacaricides.
How to get rid of spider mites chemicals? Chemical measures include:
- spraying plants working solutions of drugs;
- fumigation greenhouses and greenhouses by burning chemicals;
- soil treatment around the plants.
It implies the use of various means of biological origin. Plus this method in complete security for all creatures, excluding ticks. Measures of this method include:
- Using natural enemies ticks — phytophagous. These are predatory mites that feed on vegetarians. They effectively reduce the number of colonies without damaging the plants.
- Application biopreparationsthat harm only ticks. After preparing the solution, the plants are sprayed following the instructions.
It consists of various measures aimed at creating conditions unfavorable for the existence of a tick. To effectively use it, you need good to know habits and preferences pest. Measures include:
- soil treatment;
- destruction of plant waste;
- increased air humidity;
- planting plants that repel ticks.
Includes use improvised means to kill the pest or its scaring.
Measures are divided into:
- using food;
- the use of affordable and cheap medicines, such as iodine and potassium permanganate;
- spraying infusions and decoctionsmade from various plants.
Fighting Spider Mite On Eggplants, Tomatoes And Peppers
How to deal with pests? Tomato, Pepper and Eggplant Processing generally not different from each other. All possible nuances we have taken into account and described. If you have any suspicions about the invasion of ticks on your vegetables, you need to follow this step-by-step instruction:Carefully inspect the damaged bushes in search external lesions. Numerous small bright spots on the leaves, Availability fine spiderweb on the inside, «Marble drawing» surfaces. In addition, ticks can be detected using a strong magnifying glass.
- Spider mite on eggplant — how to fight? Remove all weed plants around eggplants and to burn them to reduce the number spider mites.
- Cut off all badly damaged leaves and shoots, not pitying them, since they still fall off themselves. Burn them immediately.
- Spider mite on pepper — how to fight? To cook soap solution from laundry soap with water. If possible, wash all affected plants using a sponge. This reduces the number of pests and removes their webs on the leaves, which interferes with the penetration of drugs from ticks. This item can be used only for processing pepper.
- Decide which means You will use to process plants from ticks.
- Spider mite on tomatoes — how to fight? Buy the drug and prepare a working solution the selected means, immediately process all bushes, following the instructions. For spraying tomatoes and eggplants concentration should be increased 1.5 times. Since they are not exposed to bathing.
A few days later, inspect the plants again to assess their condition and the effectiveness of the drug. The emergence of new points and cobwebs on the leaves indicates drug failure.
In this case, it should be replaced by another, choosing a tool from another group. For example, if you used biological acaricide, you need to choose a drug chemical origin. In order to get rid of the entire population of ticks, treatment should be carried out repeatedly.
- If plants are affected in greenhouses, the plants are treated with bleach in a concentration of 2%. In addition, carry out the fumigation of the premises, burning briquettes sulfur.
- After getting rid of pests, you should regularly assess the condition of the plants, look for traces of their presence and actively carry out preventive actions to prevent their new invasion.
If you have tried several different tools, and the result is negative, should call professionalsthat will accurately kill ticks and find the true cause of the problem.
How to process plants?
Subdivided into 2 groups:
- Acaricides specific. They act only on ticks — vegetarians and do not work against insects. These include Sunmite, Omite 30 and 57, Neoron, Apollo, Borneo, Envidor, Flumayt, Nissoran, Anticlesch, Floromite.
- Insectoacaricides. Toxic activity is manifested to ticks and insects. Possessing an extensive range of effects, most often universal. Among them, the most famous and effective Oberon, Actellic.
They contain streptomycete fungi and their activity products that have neurotoxic qualities. These include Akarin, Vertimek, Agravertin, Fitoverm, Aktofit, Kraft, Kleschevit.
Refer to gentle methods getting rid of ticks, completely harmless to any animals and people. The most popular infusions of garlic, onion, bitter pepper, tobacco, horsetail, dandelion and potato tops. Other drugs and detailed recipes can be found in our article «Folk remedies to combat spider mite.»
Diseases developing in pest attack
Spider mite not only sucks the juice and weakens these plants, but also suffers numerous diseases. First of all it gray rotto which all vegetables are subject as well viral diseases.
Eggplant suffer from mosaic — cucumber, tobacco and speckled, stolbur, viral necrosis and necrotic spotting. On pepper, thanks to ticks, lucerne, tobacco and cucumber mosaics, mycoplasmosis (stolbur) can attack. On Tomatoes seedlessness (aspermia), several varieties of mosaic, strick, spotted wilt develops.
Do not be lazy and neglect preventive measures and the fight against spider mites. Otherwise, you are likely will be left without harvest. You can select the appropriate drug using the article «Spider Tick Controls».
Spider mite on eggplant
Spider mite on eggplants is a dangerous pest that can completely destroy plants and crops. The most effective way to get rid of it are chemicals. In addition to them, you can use traditional methods of protecting plants from insects.
How to identify the pest
Spider mite is an insect of no more than 0.5 mm. To determine it with the naked eye is almost impossible.
The following signs indicate the appearance of the pest:
- the appearance of light dots on eggplant leaves;
- the leaf plate of affected plants resembles a marble surface;
- Gradually eggplant tops dry;
- spiderweb appears under the bush.
First, the spider mite feeds on the juice of eggplants, however, over time it passes to the fruits. If not taken timely measures, the plant will die within two weeks.
Signs of a pest can be seen in the photo:
A favorable environment for the emergence of spider mites on eggplants is formed under the following conditions:
- temperature increase up to 26 ° С;
- air humidity up to 55%.
Ticks multiply rapidly. During the year, up to 15 generations of new pests can appear. Spider mites overwinter in plant debris, tree bark or greenhouse.
The most effective method of dealing with spider mites on eggplants is the use of chemical agents. These include drugs whose action is aimed at the destruction of the pest. Before use, you must read the instructions.
The drug Fitoverm acts on the basis of aversectin, which paralyzes pests. The tool does not affect the eggs of the tick, so be sure to re-processing.
Phytoverm is not used with other drugs against ticks. The action of the main substance begins several hours after treatment, when the nervous system is paralyzed by pests.Important! The death of insects from Fitoverma occurs on the third day. Stronger representatives die after 6 days.
After processing from spider mites on eggplants in the greenhouse, the drug retains its properties for 20 days. In open ground with intense precipitation, dew and high humidity this period is reduced to 6 days.
To get rid of the pest preparing a solution containing 1 ml of Fitoverma per liter of water. Spraying is carried out every 20 days. This amount is enough to handle 10 square meters. m landings.
The drug Bitoxibacillin is sold in the form of powder and allows you to effectively deal with garden pests. The tool is effective against larvae and adults.
After using Bitoxibacillin, the death of the pest occurs within 3-5 days. A week later, re-treatment is carried out to eliminate the colony of new ticks.Tip! The drug should not be in contact with the skin and other organs. Therefore, it is mandatory to use protective equipment.
100 g of the product is diluted in a bucket of water, after which the eggplants are sprayed. Bitoxibacillin is used before and during flowering, the appearance of the ovary and fruits. It is not allowed to carry out processing a week before harvesting.
Another option than to treat eggplants from spider mites is Actellic. The drug acts on pests in the enteric-contact way. Depending on weather conditions and the period of development, ticks die within minutes or hours.
After treatment, the action of Actellic persists for 2 weeks. Processing is carried out in the absence of rain and wind, at an ambient temperature from +12 to + 25 ° C.Important! For spraying eggplants, the concentration of Actellik is 1 ml per liter of water.
Consumption drug is determined from the norm of 1 liter of solution for every 10 square meters. m. When used outdoors, this rate is doubled.
Neoron is a drug whose action is directed against various types of ticks. The tool copes with the pest at all stages of its development, from the larva to the adult. Partially the drug affects the laying of the tick.Important! On the basis of Neoron preparing a solution consisting of 1 ml of the substance and 1 liter of water.
Eggplants have always been treated with chemicals on the sheet. Neoron can be used with non-alkaline preparations. Its action lasts for 10-40 days depending on external conditions. Insect death occurs within a few hours after contact with treated plants.
The drug is available in the form of a powder of white or light brown color. Sunmite acts on ticks of various species, including spider webs.
The active ingredient of the drug is pyridaben, which causes insect paralysis. It is recommended to use the drug on an overcast day, since its active substance is destroyed under direct sunlight.Important! After processing, Sunmite retains the effect for 3 weeks.
The tool acts on ticks, regardless of the stage of development and is not addictive in insects. The effect of Sunmite is observed already 15 minutes after treatment.
To solve the problem of how to get rid of spider mites, a working solution is prepared. It is obtained by dissolving 1 g of the substance in 1 liter of water. Processing produces a sheet method.
With the help of colloidal sulfur, you can stop the spread of spider mites. Substance does not apply during the eggplant flowering period. The last treatment is carried out at least three days before harvesting.
Important! The protective properties of sulfur last for 10 days. The first results can be observed after 3 days.
To combat spider mite on eggplant preparing a solution containing 40 g of the substance and 5 liters of water. First, colloidal sulfur is diluted with a small amount of water, carefully triturated and mixed.
In the resulting mass is added 0.5 l of water and stirred until a solution of a uniform consistency. Then add the remaining 4.5 liters of water. Gloves are used when working with colloidal sulfur.
In addition to the main methods of getting rid of the pest, folk remedies can be used. They are safe for plants and the whole environment. They can be used to prevent the spread of mite on eggplant.
The most effective are the following folk remedies:
- Soap solution. For its preparation requires 10 liters of warm water and 200 g of soap. Pre-recommended chop soap. The remedy is infused for 3 hours. Processing is carried out by spraying eggplant every week.
- Broth tobacco leaves. Dried leaves in the amount of 50 g are poured with a liter of water and put on a slow fire. The resulting broth is diluted in equal proportions with water and used for spraying plants.
- Onion infusion. 0.2 kg of onion peel is placed in a bucket of water. The tool is prepared for 5 days, after which it is used to combat spider mites.
- Garlic infusion. Two heads of garlic need to chop, then pour one liter of water. Infusion is prepared for several days. Before using the product is diluted with water in equal proportions.
- A solution based on bitter pepper. 0.1 kg of hot pepper, pre-crushed, is added to a liter of water.
Preventing the spread of spider mites will allow compliance with simple measures:
- timely removal of weeds;
- support of humidity in the greenhouse at the level of 85%;
- there must be a distance of more than 1 m between the greenhouses to avoid the spread of the pest over the plot;
- between rows with eggplants leave wide space;
- periodically loosening and mulching the ground;
- watering plants regularly;
- conduct an inspection of eggplant, in time to identify the tick.
What to do when a spider mite appears depends on the stage of development of eggplants. The most effective are chemicals that can eliminate a pest in a short period. For prevention, you need to regularly take care of plantings.
A pest that many growers fear? That must be the tiny red-coloured spider mite. The most common species are the two-spotted spider mite Tetranychus urticae and the carmine spider mite Tetranychus cinnabarinus. These are plant feeding mites that are present on several crops all over the world. In dry and warm climates, the spider mite population develops rapidly. Time to save your crop with biological control!
What damage can spider mites cause?
- All mobile stages feed on plant sap.
- On the surface of the leaf, you can spot yellow dots as the empty plant cells turn yellow.
- The plant gets out of physiological balance due to a smaller photosynthetic area.
- Leaves turn yellow and the plant might wilt or die.
- The webs made by spider mites also reduce the esthetic value of ornamentals.
How to control spider mites?
For biological control of spider mites, you can introduce:
What are the characteristics of the spider mite?
- The first spider mite populations appear in warm and dry areas of your crop.
- The small eggs of 0.14 mm are spherical round, white-coloured and laid at the bottom of the leaf.
- The tiny larvae are colourless and have 6 legs.
- The nymphs are green with 2 body spots and 8 legs like the adults.
- The colour of the oval shaped adults of 0.5 mm can vary from yellow-brown to red-brown, depending on the crop.
- Hibernating females turn orange-red, hide in the greenhouse and reappear early in the next season, which makes them very difficult to control in this stage.
What about the spider mite’s life cycle?
- Female adults start laying eggs 0.5 to 3 days after hatching and lay eggs for 10 days at 35 °C/95 °F up to 40 days at 15 °C/59 °F.
- During warm and dry weather spider mites reproduce fast and lay about 100 eggs under optimal circumstances.
- Spider mites have 5 development stages: egg, larva, 2 nymphal stages and adult.
- It takes them about 7 days to develop from egg to adult at 30 °C/86 °F, 17 days at 20 °C/68 °F and 36 days at 15 °C/59 °F.
- Fecundated females go into diapause in autumn, when temperature and photoperiod drop.
My Greenhouse Is Too Hot! How To Reduce The Heat?
Growing plants in a greenhouse is fascinating and challenging at the same time. It is more time consuming than growing plants outdoors. Mainly because outdoor plants rely on natural elements for their needs. In a greenhouse you are in charge to provide fruits and vegetables with water, warmth, humidity and food.
The first basic need is water. It is not only about forgetting to water a plant. Most of them actually suffer from overwatering as these plants need a resting period. Learn how to water plants in a greenhouse and what watering systems you can use.But today we are going to talk about temperature in a greenhouse. We will find out why your greenhouse is too hot and what actually grows well in higher temperatures.
How hot should a greenhouse be?
For most greenhouse and conservatory plants the temperature range of 55°-75°F (13°-24°C) is hot enough for active healthy growth. That is comfortable temperature for seedlings and mature plants. However, you should keep you greenhouse hotter than this for germinating seeds. Also, keep in mind that mature plants can tolerate fluctuations outside the comfort range rather than young plants.
It is important to understand that minimum temperature requirement is for the plant to flourish. Even though most plant types can grow at temperatures below the stated minimum, this tolerance is not large. That it why you should not mix heat loving plants with hardy plants.
So, what to do if you want to have a mixed collection? Simply divide a section of the greenhouse with transparent material for warm loving plants. You can also line the sides and roof with bubble wrap to trap the heat. Place a heater in the warm section. Use this guide on the cheapest greenhouse heaters to run.
Does greenhouse get too hot in summer?
The temperature in a greenhouse rises in late April or May. In summer months greenhouse can get too hot with temperatures over 85°-90°F (29°-32°C). These temperatures can result in fatal damage to plants. When plants get too hot in a greenhouse the lower leaves start to wilt and edges turn brown.
Moreover, when it is too hot plant’s bottom leaves fall and plant growth is spindly. Also, flowers are short-lived and start to fall off. Dry heat is more dangerous for plants that moist heat. You must keep the day-time temperature fairly constant during growing season.
What grows well in a hot greenhouse?
You can grow a variety of warm loving plants in summer when a greenhouse is hot. Ideal temperature for Chrysanthemum is 60.8°F while Cucumber and Tomatoes thrive in 65°-68°F. Cacti and melon grow well in a hot greenhouse as they need a temperature of 71.6°F and 75.2°F respectively.
How to reduce the heat in a greenhouse?
The best way to reduce heat in a hot greenhouse is damping down. All you need to do is to use hose pipe to wet the floor and benches. Once a day is enough in April-May but wet surfaces as often as three times a day in midsummer. Oh hot days you need to mist plant leaves with water.
When damping down water evaporates and the temperature in a greenhouse lowers. It also increases air humidity resulting in reduced water loss through plant leaves. This leads to less frequent watering, however, moisture-loving plants are still able to survive.
Moreover, damping down helps to control greenhouse pests. For example, some pests like red spider mite and thrips live in dry air. To lower the temperature in a greenhouse, you need to damp down the floor and mist the plants when the structure is adequately ventilated.
However, the benefits of manually damping down the floor and benches are temporarily on a hot day with all the vents open. If you are growing professionally, you can invest in electronic humidifier which provides water vapor continuously.
If you are a hobby gardener, you can lay down capillary matting on the staging to create a continually damp area. Even though you are damping down, misting and ventilating, greenhouse is till hot? Let’s find out why does greenhouse get hot.
How does a greenhouse work?
A greenhouse traps radiant heat from the sun, so the sun rays pass through the greenhouse glazing. The greenhouse plants and objects inside the structure absorb the sunlight and convert it to heat. Then air, evaporating water and objects inside the greenhouse store the heat. This heat is unable to leave the structure, as a result, it stays inside the greenhouse and keeps it warm.
So, even though a greenhouse should be in full sun, it is essential to apply some sort of shading to maintain temperature at or above 75°F. A direct summer sunshine can burn Begonia, African Violet and Gloxinia plants. There are four simple ways to shade a greenhouse.
If you have a small greenhouse, it can be enough to place small plants in the shade of larger ones. Moreover, you can place a newspaper over seedlings, rooted cuttings and plants with delicate leaves. However, if you live in sunny climates or high altitude areas, it might not be enough, so I can recommend using a shade cloth.
How To Get Rid of Spider Mites in the Indoor Garden
This article written by Chris Bond about how to get rid of spider mites was originally published in 2015, Garden Culture Magazine US Issue 8. It originally appeared under the title, A Mite-y Problem.
Few pests bother the indoor gardener like spider mites. They seemingly appear from nowhere, and spread havoc exponentially. The secret to how to get rid of spider mites in the indoor garden? Control. Knowing how to control your growing environment is one of the best ways to control these pests.
Spider mites are small, sucking pests that can be difficult to see without the aid of magnification. They are usually brown or translucent, yellow or green in color, sometimes red, and are as small as 1/50th of an inch (.5 mm). A hand lens of at least 10X magnification is usually required to positively identify spider mites. Both the adult mite, and their immature progeny can do extensive damage to plants. The most common species encountered by the indoor or home gardener is the two-spotted spider mite, Tetranychus urticae Koch. They are known to affect well over 200 species of garden, field, greenhouse, and hydroponic crops.

The life cycle of spider mites is very rapid. It can vary some between species, and varies with temperature, but with all mites, it includes the egg stage, the larval stage, two nymphal stages (protonymph and deutonymph), and the adult stage. At about 80°F, (26.7°C) spidermites evolve from egg to adult in as little as five days. It can take several weeks in cooler temperatures. When unchecked, there are many generations of spider mites per year. Adult females live for up to one month, and can lay several hundred eggs during that time.
Mites do their damage to plants by sucking out the sap from the leaves. Their pattern is to start on the undersides of leaves, and then move from leaf to leaf, as they drain the plant of its vital liquid, and as the mite populations continue to explode. Damage to plants from mites appears as yellow-speckled or mottled leaves, appearing on the undersides of leaves or needles first, but quickly evident on the tops as well. If unchecked, the leaves eventually turn yellow or brown, and the entire plant will die due to its inability to photosynthesize.Like spiders, mites spin webs. They travel about on their network of fine webbing, and often this is visible after mite populations start to swell.
To test for the presence of spider mites, place a sheet of white paper under the leaves of your plants, and tap or shake the leaves. If there are mites present, some should fall on the paper and appear as moving specks across the paper. Black specks of frass (fecal material), amber-colored eggs, and white skin-castings are another sign that mites are present.
Mites are often inadvertently spread by people. An innocent visit to a local garden center can mean returning to your grow area with some unwelcome hitchhikers. If possible, change your clothing before entering your garden spaces, and make sure to sanitize your hands thoroughly before and after tending to your plants. They can also travel on a slight breeze on their web. They do overwinter outside under leaf litter and other organic debris, so it is possible that an otherwise clean growing area, can quickly become a host site for a spider mite outbreak when it warms up in the spring.
Their natural distribution is throughout Europe and North America, ranging from temperate zones through the subtropics. They can survive through even the harsh Canadian winters in the microclimates created near homes and buildings. Mites do best in warm and dry conditions. If possible, your grow area should be kept as humid as possible, or at least as much as your indoor plants and crops can tolerate. This can be done by periodically misting your plants, undersides too, with a spray bottle. Make sure also that you do not let your soil get too dry between waterings either, as this can promote the spread of mites as well.

Anytime that you intend to introduce new plants to your growing areas, they should be temporarily quarantined to make sure they are not housing a mite population. Further prevention includes selecting species of plants that are known to be less susceptible to mite damage.
How to Get Rid of Spider Mites? Control…
Spider mites are not true insects. For this reason alone, many gardeners fail to control them with widely commercial insecticides. They are 8-legged arachnids, and can only be controlled with miticides, or those formulations and controls which are meant to kill or disrupt the biological activities of spiders or ticks. If possible, take your plants outside to treat them, so that you are not just knocking the mites off, only to return to their original host, or to move on to another. If this is not practical, the same effect can be achieved by taking your plants into the bathtub to treat them so that any mites knocked loose simply disappear down the drain. This option, though should not be used with chemical insecticides, as they will eventually find their way into the water supply.
Regardless of your choice for organic, natural, or synthetic control, it is wise to treat only a small area of an infected plant first to check for phytotoxicity, which causes damage to the plant by the remedy. Some formulations can actually burn leaves of sensitive plants, so it’s best to read the entire label to make sure that the plant or crop that you wish to treat is appropriate for the pesticide selected.
Some natural or organic remedies for control include using a forceful stream of water to dislodge them from your plants, applying insecticidal soap, or horticultural oils (these should be at about 2% oil to prevent foliage burn). Homemade insecticidal soaps can be concocted with 2 teaspoons (10 mL) of a mild dish soap mixed with a gallon (3.8 L) of slightly warm water. A disposable paint brush or toothbrush can be used to spread the soap onto the leaves, ensuring contact with the mites, as well all knocking them off. Neem oil is an effective pesticide that also has fungicidal properties as well. Soaps and oils should be applied about once per week until no further damage is noted. As they hide out mostly on the undersides of leaves, it is important to make sure that both sides of the leaves are treated. Sulfur can be an ingredient in both natural and synthetic mite control. It can be found in spray or dust form.
Chemical control includes miticides or acaricides (another name for pesticides that kill mites) containing bifenthrin, abamectin, bifenazate, hexythiazox, or spiromesifen as their active ingredients. Just like with natural controls, it is important to treat the undersides of the leaves, unless the pesticide is trans-laminar, meaning that a surface treatment will migrate through the leaf, and will kill the mites or insects on its underside.It should be noted that the reason spider mites are such a bane to growers is their high adaptability to synthetic pesticides. Those that are not killed by a pesticide due to their genetic resistance pass those genes on, and before long, chemical pesticides are rendered useless, because the mites are unaffected by them.
Pesticide applications also inadvertently kill the beneficial insects that help to control the populations of spider mites. A typical scenario is that repeated applications of any chemical pesticides results in an environment where there are few to no natural enemies of spider mites, and a population of “super” spider mites that are not susceptible to the active ingredient in the pesticide develops. For these reasons, no one method should be relied on alone, or for any extended period of time. Those formulations that are effective on the adult spider mite,
are not typically effective on penetrating the egg, and are not always useful in killing the larval or nymph stage as well. This is one of the reasons that multiple applications of pesticides are generally needed for effective control.
Spider mites can spread easily by the slightest breeze, or by traveling unbeknownst on clothing. They reproduce quickly in warm and dry climates, and are difficult to control with conventional insecticides. The most effective way to protect yourself from an outbreak is through sanitation, and vigilant monitoring. Action should be taken at the first sight of spider mite damage, and should not be done with half-measures. When possible, dispose of affected plants before the mites get a chance to spread to others.
