Everyone who planted potatoes at least once, faced such a scourge as the Colorado potato beetle. This insect is so adapted to the various conditions of life that even many poisons are not able to overcome it. That is why experts in the field of agronomy have developed a special drug Aktar, which will protect your crop from permanent pests and will allow you to grow high-quality and healthy plants.
Description and properties of the drug
The uniqueness of Aktara is that it can be used not only to protect potatoes from the Colorado potato beetle, but also currants from aphids, as well as from various pests that impair growth and destroy roses, orchids and violets. Aktara is a neonicotinoid type insecticide.
Almost a day with this drug against the Colorado potato beetle, you can forget about this pest. So, after 30 minutes after treatment, the pests will no longer eat, and the next day their death occurs.
If you bring the Aktara remedy under the plant root, then the protection will last for 2 months, if the drug is sprayed, the plant will be protected for 4 weeks. In any case, at the time you save the plants from painful insects.
In what form is produced
The drug is available in several forms: liquid concentrate, as well as special granules. So, the granules are packed in a small package in 4 g. Experts say that there will be enough sachet to process all greenhouse tomatoes.
The suspension concentrate is available in 1.2 ml ampoules, as well as in 9 ml bottles. Such packing is convenient for processing houseplants or small summer cottages.
For enterprises that are engaged in the cultivation of agricultural products, special packaging is produced in 250 g.
How to use a remedy against pests
Means Aktara from the Colorado potato beetle, the instructions for use of which is quite simple, has reviews not only gardeners amateur, but also serious experts in the agricultural sector.
Attention! The most important point is to start processing on time.
Simply put — as soon as pests are found on the plants, immediately open the packaging and proceed to processing.
Choose a day without wind, and also see the forecast so that it does not rain. Spraying is carried out in the morning and in the evening. Choose a good spraying drug so that it does not crash and is not clogged. At the end of the work the sprayer is washed with plenty of water.
So, it is necessary to prepare a solution, do it only in open space. In 1 liter of warm water, dilute 4 g bag of the drug. The working fluid is prepared in the sprayer itself, which is filled with water for ¼. If you are sprinkling potatoes, then you need to add 150-200 ml of the product; if currants are being processed, then 250 ml, you will need 600 ml for the flower cultures.
Using the drug Aktara, you get a lot of advantages:
- protection against more than 100 pests;
- active penetration through the leaves. The drug is absorbed after 2 hours and the rain does not have time to wash off the protection;
- practically does not penetrate the fruits themselves;
- the agent can be mixed with other drugs, as well as added to the fertilizer. The drug is incompatible only with alkali based products;
- activates the development of the root system;
- the drug is harmless to insect predators that feed on pests.
But most importantly, it is protection from the Colorado potato beetle. Aktara is a reliable tool that will protect your harvest from unexpected guests.
Experts also recommend alternating the drug with other means of protection so that some types of pests do not develop resistance to the drug.
Reviews of Aktar means they say about its reliability and long-lasting effect. It is also used before planting, dipping tubers or bulbs into the solution. Experts say that you can not be afraid of an overdose of harmful substances, since the drug is completely decomposed in just 60 days.
However, experts note that the drug is moderately dangerous for people and has a class III toxicity. This suggests that when working with the tool, you must use gloves and a respirator, as well as special clothes that you will wash after each treatment. In addition, you should also wash all the tools that were involved during the work, as well as the need to take a shower and brush your teeth.
Tip! If you plan to process indoor flowers or some other plants, they must be taken out on the air.
The following point also applies to precautions: to avoid poisoning or accidental ingestion of the drug in the stomach, do not use various food containers or usual containers for storing food or water to dilute it.
We also note, despite the fact that Aktara does not represent a particular danger to birds, fish, earthworms, it is still undesirable to pour its remains near water bodies or clean springs. However, the drug is harmful to bees, so they are released only 5-6 days after treatment of plants. Numerous reviews about the drug also indicate that it is impossible to walk cattle on the plot treated with Aktar, and you also need to ensure that the substance does not get into their feed.
Aktar is recommended by experienced gardeners, as well as experienced agronomists:
Dmitry, 68 years old, near Moscow I use Aktar only to fight the Colorado beetle. They already adapted to everything, nothing takes them. But this tool showed itself from the best side. My potatoes are now always safe and sound. Well and so on trifles sometimes a currant and flowers I spray. Only you need to be always careful, prepare in advance uniforms: gloves are mandatory, a respirator, you can mask. Drug needs to be dissolved and right there to use. And a fine day, choose so that without the wind, well, and the rains, as it will. In principle, Aktara is quickly absorbed, so the rains are not terrible. Larisa, 34 years old, Krasnodar region Aktara practically saved orchids from certain death. Before that, no drug could cope, because there are many pests, and the effect of the drug is short. Just the reviews influenced my choice, now I recommend it. The tool has a long-lasting effect, it has exterminated all these terrible insects that literally ate my beautiful flowers. Helena, 38 years old, Tomsk. I have been using Aktar for several years in a row. A wonderful thing, once discovered it from reviews. I sprinkle both potatoes in the country, and indoor flowers. I usually bring them to the cottage and there I am already conducting all the procedures. And, by the way, this substance is enough, and the price is affordable. I’m happy.
Protection of potatoes against the Colorado potato beetle before planting
In many regions of Russia, planting potatoes suffer from the invasion of the Colorado potato beetle. Adult beetles are less harmless than their larvae. They, like the «red berries» stick over the potato bushes, completely devour the whole tops, leaving only the petioles.
Naturally, damaged plants are not able to recover quickly, the crop is reduced several times. Gardeners are trying to find ways to combat the pest. Processing potatoes before planting from the Colorado potato beetle is an effective method. Today, you can pick up the appropriate drugs to protect the tubers from pests.
The impact of the Colorado potato beetle on yield
Back in the late 19th century, unknown beetles damaged potato plantations in the fields of Nebraska. After 4 years, the mass of beetles has increased significantly, they were able to reach the state of Colorado. Here the damage was significant. After this, the beetle became known as the Colorado.
Beetles and their offspring are voracious. Adult beetles damage the tubers themselves. The object of nutrition is not only potatoes, but also eggplants, tomatoes, sweet peppers, physalis, dereza, henbane. Do not give up some colors that also belong to the family of the nightshade. The most voracious in the family are the larvae.
Comment! One larva requires from 50 to 110 mg (depending on the age) of the green mass of potatoes for full saturation. During life time — 750 mg.
During the entire vegetative period, it is necessary to fight pests with various means. But you can protect the seedlings at the very beginning of the growing season, if you specifically treat the tubers with preparations from the Colorado potato beetle.
Adults overwinter in the soil at a depth of 30 to 50 cm. They do not stop at tubers. There have been cases when an insect was found when cleaning potatoes.
Ways to protect
The task of vegetable growers is to protect the planting of potatoes from the invasion of the Colorado potato beetle. Processing tubers need to deal with planting. There are professional (use of chemicals) and folk methods of protection. Let’s try to understand them.
Processing of potatoes before planting from the Colorado potato beetle involves the use of pesticides. There are drugs of foreign manufacture, they were used until recently. Today, the Russian chemical industry has produced a lot of high-quality products that are not inferior in their properties to foreign analogues. Their quality can be judged by the numerous reviews of vegetable growers.
Attention! Foreign and Russian plant protection products have the same effectiveness, since the compositions are almost identical. But the cost of Russian drugs is much lower.
What Russian means of protecting potatoes from the Colorado potato beetle can be used:
- Prestige — reliable protection of landings. To prepare the solution for the treatment of potatoes, 50 ml of the product are diluted in three liters of water.
Gardeners, as a rule, prepare about 50 kg of potatoes for planting. The resulting solution is sufficient. Plants will receive reliable protection.
- Maxim is most often used with Prestige. Maxim processes not only the tubers, but also pickles the soil, where insects can winter.
- Kruyzer acts effectively. Not only protects the tubers from the Colorado potato beetle, but also does not allow the spread of viral diseases. Landings are protected for six weeks.
- Taboo saves not only from the Colorado potato beetle, but also from all pests (especially the larvae of the click beetle) living in the soil. Treated tubers under reliable protection for at least one and a half months. Precipitation does not reduce the action of the drug.
Tip! The protective effect can be enhanced if you use chemicals not one by one, but in combination.

Potatoes: Plant Care and Collection of Varieties
There has a resurgence of interest in home-grown potatoes, especially now that they are available in a wide variety of colors, shapes, and tastes. Most gardeners plant «seed» potatoes, a confusing term since these aren’t seeds at all but rather small potato tubers. For best results, purchase certified seed potatoes; these will have been inspected to ensure they are free from disease. Avoid planting supermarket potatoes, because they may have been treated with a growth inhibitor to prevent them from sprouting. Consider trying some unusual varieties, such as fingerlings or blue potatoes.
Choosing a site to grow potatoes
Select a site with full sun and deep, well-drained soil. Prepare the garden bed by using a garden fork or tiller to loosen the soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost.
Buy seed potatoes of early varieties for planting as soon as soil can be worked in the spring. In the North, plant seed potatoes of later varieties from mid-May to early mid-June, 4 to 5 weeks after planting early varieties. In the South, plant seed potatoes of late varieties 1 to 2 weeks after early varieties. Cut seed potatoes into small pieces with two to three eyes per piece a few days before planting. Dig trenches 6 inches wide, 6 inches deep, and 30 to 36 inches apart. Space seed potatoes 10 to 15 inches apart in the trench and cover with about 4 inches of soil.
Protect emerging plants with soil or other cover in case of a hard late spring frost. Hill the soil up against the plants about a week after leaves emerge from soil. Repeat 2 to 3 weeks later. Be sure to provide adequate water 6 to 10 weeks after planting, when the potatoes start to form. Contact your local County Extension office for controls of common potato pests such as Colorado potato beetle, European corn borer, and leafhoppers.
How to harvest potatoes
Harvest small, new potatoes about 10 weeks after planting. Harvest storage potatoes after the vines have died and tubers have developed tough outer skins. In the North, harvest before fall frosts arrive.
Best and Worst Companion Plants for Potatoes

When planning your garden, potatoes offer a unique challenge, since there are many plants that grow well in close proximity to potatoes, but there are also a group of plants you should avoid planting near them. An understanding of companion planting strategies will help you understand how best to plan your garden and where to plant potatoes without necessitating a lot of heavy-duty chemical pesticides.
Principles of Companion Planting
Companion planting can be defined as the practice of planting different species of plants close together based on their ability to enhance one another in some way. Plants can be defined as good companions for a number of different reasons, and the gardener may want to emphasize one reason over others when laying out a garden. Common reasons why plants might be regarded as good companions include:
- Non-competing growth habits: Plants may have different but complementary growth habits that do not compete with one another. Pairing tall upright plants with ground-hugging vines, for example, can offer efficiency in the use of garden space. Or pairing deep-rooted vegetable with shallow-rooted vegetables may offer similar efficiency.
- Similar growth needs: Plants may have similar needs for fertilizing, water, or sunlight, which makes it easier to take care of them. Pairing together plants with high water needs, for example, can make it easier to water all of them at the same time.
- Pest deterrent: Some plants may be known to repel certain insect pests that feast on a particular plant. Marigolds, for example, are good companions for many plants for this reason. Other plants actually draw in beneficial insects that serve as predators for harmful insects.
- Soil balance: Plants use different nutrients in the soil, preventing depletion of the soil and reducing the need for fertilizing.
- Nutrient-rich: Some plants may actually improve the nutritional value of the soil. Legumes, for example, are good companions for many plants because they «fix» nitrogen and make it available for many other plants.
- Flavor enhancer: Some plants may enhance the flavor of other edible plants when they are grown close together.
Good companion planting strategies are especially important in small gardens or wherever careful space planning is needed.
Companion planting can be more complicated than it first appears since it requires a gardener to prioritize the benefits and drawbacks of pairing the different companions in a particular garden setting. What is a good companion plant in one garden may not be a good companion in another garden in a different region. The preferences of the gardener also play a role. For example, a gardener devoted to organic methods may view good plant companions differently than a gardener who is not squeamish about the use of fertilizer.
Good Neighbors for Potatoes
Potatoes are deep-rooting vegetables, which logically suggests that the best companions will be those with above-ground growth habits that do not infer with the root systems of the potatoes. Lettuce, spinach, scallions, and radishes are shallow-rooted veggies that are a good choice for occupying the spaces between potato plants. Because potatoes are harvested late in the season, the best choices for planting right around the potato hills will be early-season vegetables that will be harvested well before you need to stomp around the garden to keep up the potatoes.
There are several plants that are said to enhance the flavor of the potato tubers, including chamomile, basil, yarrow, parsley, and thyme (they also welcome in beneficial insects). Beans, cabbage, and corn all will help potatoes grow better and hence improve the flavor of the tubers.
Beans and other legumes are good companion plants for most vegetables since they increase nitrogen levels in the soil.
Horseradish is said to make potatoes resistant to disease, and petunias and alyssum will also attract beneficial insects that feast on insects destructive to potatoes. Colorado potato beetles are a particular problem for potatoes, and among the plants that repel this damaging pest are tansy, coriander, and catnip.
Neighbors to Avoid
Proper companion planting technique can also mean not putting some plant species close together if they have a bad influence on one another. Some reasons for avoiding close planting include:
- Plants may influence the taste of other plants negatively
- Plants may compete with one another for sunlight, soil nutrients, or space
- Plants may lure the same destructive insects
- Plants may have similar disease susceptibility
Although it is in the nightshade family, you should avoid planting potatoes near any other plants in the nightshade family. It is even best to avoid planting potatoes is the same soil where nightshade plants have recently been grown. This includes eggplant, peppers, and tomatoes. Since potatoes are in the nightshade family, and hence they are susceptible to many of the same diseases as other members of the family. Planting nightshade species close together (either in space or in time) creates optimal conditions for certain fungal and bacterial diseases to thrive. You should allow a full two years before replanting a nightshade plant in the same soil that has previously grown other nightshade plants.
There are a number of plants that apparently increase the likelihood of potato blight. These include raspberries, sunflowers, pumpkins squash, and cucumbers.
Asparagus, carrots, fennel, turnips, and onions seem to stunt the growth of potatoes.
Processing of potato tubers before planting from phytophthora
Phytophthora is a fungus that infects solanaceous plants: potatoes, tomatoes, physalis and eggplants. The greatest aggressiveness of the disease falls on foggy, wet weather. Phytophthora declares itself with large differences between day and night air temperatures. There is a high risk of disease when heavily planting crops. The likelihood of late blight increases when placing a number of beds with solanaceous plants (eg, tomatoes and potatoes).
The disease manifests itself in the form of indistinct patches of gray-brown shade on the tubers, leaves and stems of the plant. Sick potatoes can not be eaten.
How to treat potatoes before planting from phytophtora, how to protect plants in the subsequent stages of development — this article is devoted to this.
How to prepare the soil
In winter, at low temperatures, the majority of pathogens phytophthora in the soil die.
Tip! Do not be lazy in the fall to remove from the site the old tops and last year’s potato tubers. Collect them and burn them.
It is undesirable to plant potatoes several times at the same place. The best is a break of 2-3 years.
Good prevention of late blight — tillage with means of «Baikal EM-1» or EM-5, it allows you to get rid of the rest of the fungus in the soil.
Selection rules for planting material
Tubers intended for planting, carefully inspect, discarding the diseased. Before planting, it is necessary to divide the tubers of different varieties in order to place them in different beds. Pay attention to varieties that are resistant to late blight infection. These are the following varieties:
If you choose these varieties for planting, then you can be calm: your crops do not face a fungal infection.
How to germinate tubers
Before germinating potatoes for planting, wash and dry the tubers. Do not keep them in water or damp, as they will start to rot. Germinate planting material preferably in a well-lit room with good ventilation. The temperature in the room ranges from 10 to 15 degrees. Sprout the tubers, putting them in cardboard boxes or boxes in two layers. Turn the tubers periodically to make the sprouts tighter. Also ensure that the boxes are lit evenly.
Chemical treatment of tubers
Disinfection of planting material reduces the likelihood of the disease of potatoes, including late blight — including. However, it is necessary to observe security measures in order to protect the potato from contamination and not to turn it into a product dangerous for health, «stuffed» with chemistry. Therefore, before processing, you need to carefully study the instructions and follow it strictly.
Tip! Helps against phytophthora infection processing of potato tubers before planting such complex preparations as «Prestige» and «Maxim».
In addition, it is a good protection against potato scab and Colorado potato beetles. Their disadvantage is a high percentage of toxic substances.
Quite good results are given by means of the Fitosporin of complex action. Among the diseases of fungal and bacterial origin, which suppresses the drug, there is late blight. An important point, in addition to effectiveness, is the safety of the drug and the possibility of its use at all stages of plant development. Powder dosage — 20 g per 10-liter bucket. Spraying frequency — 2 weeks.
For the prevention of phytophthora produce spraying of planting tubers in the period of germination and immediately before planting potatoes.
Folk methods of planting material processing
- Add in a 10-liter bucket of water 1 kg of ash, stir. Putting the potatoes in the mesh bag, dip it into the solution. Handled immediately before planting.
- Dissolve 1 g of potassium permanganate and a matchbox of copper vitriol in 10 liters of water. Spraying tubers before planting protects against fungal infections.
Disinfectant mixture based on mineral fertilizers
At 10 liters of hot water accounted for.
- Urea — 40 g.
- Copper sulfate — 5 g.
- Mangantsovka — 1 year
- Boric acid — 10 g
- Superphosphate — 60 g.
Mix all ingredients. After cooling, soak the planting tubers in a solution for half an hour. After that, you can dry the potatoes and put in boxes for germination.
If detected phytophthora: folk methods for plant protection
Despite the simplicity, these tools help to effectively fight late blight.
- Garlic infusion. Chop 100 g of garlic and leave in 10 liters of water for 24 hours. Strain the solution before use. Spray the potatoes every week until the phytophtora is gone completely.
- Kefir solution. Dissolve 1 l of peroxide kefir in a 10 liter bucket of water. Strain the solution. Spray weekly until fungus is completely removed.
- Bordeaux mixture. Dissolve 200 g of copper sulfate in 10 liters of water. The effectiveness of the solution is enhanced if boric acid and manganese are added to the solution.
- Iodine solution. This antiseptic is useful not only to people, but also to plants. At a 10-liter bucket of water enough 20-30 drops of iodine. The frequency of processing — every week.
- Ash. Mix 0.5 buckets of wood ash with 10 liters of water. Infuse the mixture for 4 days, stirring occasionally. All this time, wood ash nourishes the water with nutrients. On the 5th day, dilute the mixture to 30 liters, dissolve 50 g of soap in it and go to save the harvest.
- Yeast solution. Dissolve 100 g of yeast in 10 liters of slightly warmed water and leave the mixture to ferment for 24 hours. When symptoms appear on shrubs, spray the plant with a yeast solution.
Compliance with crop rotation and planting rules, processing of plants before sowing and at different stages of their development will allow you to avoid the defeat of potatoes by fungus. To carry out the treatment or not is up to you, but, as practice shows, the cultivated tubers give the best yield, and the probability of illness decreases.
