The choice of chemicals that destroy the Colorado potato beetle, but safe for humans

It is quite difficult to get rid of the Colorado potato beetle without the use of special means. The pest invasion begins in the spring, and experienced vegetable growers advise using a remedy for the Colorado potato beetle already at this stage. These parasites can destroy the entire potato crop.

Potato pest - Colorado potato beetle

An adult pest is a beetle about 1 cm in size. It has characteristic black stripes on its shell. Not only adults, but also the larvae of this parasite, pose a great threat to the harvest. The parasite is able to withstand the winter period - an adult pest sneaks under the soil and returns to active life only in spring.

The colorado potato beetle larva is unable to survive the winter and dies during the first frost. Coming out of hibernation, the beetle is able to travel more than 1 km per day in search of food. It is generally accepted that the Colorado potato beetle can only eat potato leaves, but this opinion is not entirely true. The pest feeds on all plants from the species of nightshade - pepper, tomatoes, eggplants, etc. But they pose the greatest danger precisely to young shoots of potatoes.

During its life cycle, one female beetle lays about 500 eggs in small clutches of 20 pieces. The greatest threat is posed by the larvae of the pest hatched from these eggs. The development of the larvae lasts about 3 weeks, after which they hide underground for further pupation. But these 3 weeks are usually enough to destroy the entire crop.

Fighting the Colorado potato beetle with chemicals

Chemical preparations for the Colorado potato beetle are most effective in combating the pest, of which there are a great many on the market now. Many of the drugs are not hazardous to human health. You just need to follow the precautions and follow the instructions.

Biological preparation "Colorado potato beetle NO"

Before starting to describe chemical pest control products, I would like to note a novelty on the market called a new generation biological product. This product consists of organic substances that are completely safe for the human body. The drug is produced in France and it is not so easy to find it on the Russian market.

The main active ingredient of the drug is Indian Azadirakhta oil. The agent repels insects, it prevents the reproduction of adult beetles and negatively affects the development of the larvae. Processing of potatoes from the Colorado potato beetle is carried out three times per season. It is necessary to dilute the substance in water. The ratio of the drug to water should be 1:40.

Terms and number of treatments:

1. The first time the potatoes are processed before planting from the Colorado potato beetle. Hand sprayer the hole is processed into which the potatoes are placed.
2. The second treatment is carried out at the time of the first shoots.
3. The third, final treatment takes place two weeks after the second spraying of the shoots.

For one hundred square meters of land, about 10 ml of the product is used. That is, three treatments require 30 ml of "Colorado potato beetle NO". There are few reviews from real users so far, but most say that this is reliable protection against the Colorado potato beetle.

Further we will focus on the chemicals that have received the largest number of real reviews on the network. There are a huge variety of drugs on the market that differ in both price and mode of action. It's easy to get confused in such a variety. The picture is also spoiled by unscrupulous manufacturers, who very often hide the side effects of released drugs.

Bordeaux mix

The most popular among modern vegetable growers received bordeaux mix, which is completely harmless to humans and has an excellent effect. When the growth of young shoots of potatoes is about 15-25 cm, it is necessary to process the crop with Bordeaux liquid.

Terms and order of processing:

1. During the first treatment, it is necessary to dilute the following solution: 150 grams of lime per 150 g of copper sulfate and 10 liters of water.
2. The second treatment is carried out exactly 12 days later with a solution of 200 g of lime, 200 g of copper sulfate and 10 liters of water.
3. A third treatment may be necessary. For this, 200 grams of lime is again used for 200 g of copper sulfate and 10 liters of water.

This tool will help to get rid of not only the Colorado potato beetle, but also from a common potato disease - late blight.

Bayer Prestige KS

The remedy for the Colorado potato beetle "Prestige KS" from the German manufacturer Bayer is now gaining more and more popularity among vegetable growers. This product contains two active substances:

• fungicide pencycuron;
• insecticide imidacloprid.

The first substance is aimed at protecting potatoes from various diseases, and the second fights pests. "Prestige KS" has a pronounced anti-stress effect, and also stimulates plants for active growth. Among all drugs currently on the market, Prestige KS is one of the most expensive.

The insecticide fights against wireworm, Colorado potato beetle, bear, aphids, various carriers of viruses, as well as diseases such as rhizoctonia and common scab.

The manufacturer's instructions indicate that potato tubers must be processed in a net or crates. This process must be carried out in order for the agent to be evenly distributed over the tubers. However, if the seed tubers have already sprouted, then you should not process them this way. It is enough to spray the potatoes in the hole.

Let the buyer not be confused by the bright crimson color of the product, which becomes less saturated after preparing the solution. After processing, potatoes will also be colored in the color of the substance. The manufacturer claims that the product protects potato tubers from pests for 50 days, and from diseases within 40 days from the moment the solution is applied.

Only after 50 days, the agent disintegrates into harmless compounds. The instructions say that potatoes can be eaten only 50 days after the tubers are planted. Many vegetable growers are alarmed by this fact, however, manufacturers claim that the drug rises to the leaves along the stem during the growth of the plant. An insecticide cannot get inside young tubers, since it does not take part in the process of photosynthesis.

The action of the poison from the Colorado potato beetle ends on the 50th day. From this point on, the leaves become edible again for pests.

Of course, by this time the parasites do not pose any danger to the potatoes, since the tubers have already set. Nevertheless, it should be understood that the second wave of the Colorado potato beetle will go underground for wintering, and will reappear in the spring. This insecticide will not help against pests in the new season, but will allow you to grow a healthy potatoes in the current. To protect against the second wave of the Colorado potato beetle, the bushes should be treated with a different drug.

Bankcol

Another effective remedy for the Colorado potato beetle, which allows you to get rid of both adults and young individuals of the pest after the first spraying, is Bankol.Sold in packs of 500 g. It is a wettable powder.

The main advantage of this drug is that the larvae of the pest die immediately after they begin to eat the leaves treated with the drug. This poison from the Colorado potato beetle does not require re-treatment.

The main disadvantage of this drug is that it dampens the reproductive function of potatoes. Manufacturers claim that the substance decomposes into safe components within a week after processing. This preparation is ideal for those who do not leave seed potatoes.
