Probably, there is no such pest that would cause so much damage to garden crops as the Colorado potato beetle. Eggplants, tomatoes, peppers and especially potatoes are affected. With a large accumulation of this pest, planting potatoes can be completely eaten literally within a week. This "feat" this bug made in the United States in the nineteenth century, leaving the whole state of Colorado without potatoes, which is why it got its name.
Life cycle of the leaf-eating pest
The life cycle of the beetle begins in the spring, when adults crawl out of the ground after hibernation. Mating occurs immediately, after which the female lays eggs on the inner surface of the leaves.Tip! It is at this time that you can easily deal with future larvae.
For this you need to carefully examine the bushes and destroy the laying of eggs. After about two weeks, and in hot weather even earlier, the larvae will hatch from them, which are much harder to fight.
Larvae grow quickly and are voracious. In order not to lose the crop, they, as well as adult beetles, must be fought.Attention! In the middle lane over the summer, one pair of beetles can give life from 700 to 1000 larvae. In the north, their number is 2-3 times less.
You can collect these pests manually, fight them with folk methods, but all these methods are not always effective and require repetition. A radical way - the fight against the Colorado potato beetle with insecticides.Tip! Each gardener has the right to decide what is more important to him - the complete destruction of pests or the preservation of ecology on the site, but to the detriment of the crop.
There are enough tools that effectively help to deal with this problem. The main active ingredients used to combat insects are several.
- Organochlorine compounds.
- Artificially synthesized pyrethroids, analogues of natural pyrethrin.
- ORGANOMETALLIC COMPOUNDS.
- Organophosphate compounds.
Clotiamete from the Colorado potato beetle
It is based on the latest compounds created by the drug Clotiamet from the Colorado potato beetle, user reviews about it are very good.
Mechanism of action
The main active ingredient of this insecticide is clothianidin. It belongs to the group of neonicotinoids. These drugs are related to the well-known nicotine, but, by contrast, are much less toxic to humans and mammals. Target insecticide Clotiameta - the nervous system of insects. It blocks nerve impulses, causing paralysis and death of insects, including the Colorado potato beetle. The drug acts in three ways: contact, through the intestines, getting into all organs and systems of insects.
When processing potato plants, the drug is absorbed not only by the leaves, but also by the roots. Pests eat insecticide-treated leaves and die. The drug acts from the moment of treatment, and the death of pests occurs no later than a day. Clotiamet protects potato leaves for about two weeks.Attention! The drug is only half decomposed after 121 days. Easily destroyed by the action of sunlight.
How to apply
The preparation for processing requires quite a bit. If you follow the instructions for use, only 0.5 g of Clotiamet diluted with 2 liters of water, with which it forms an emulsion. After thorough mixing, add another 8 liters of water. This amount is sufficient for processing 2 acres of potato field. The treatment is carried out using a spray.
A warning! To work with Clotiamet use only plastic or enamel ware.
Processing can be carried out only once, it should be timed to the mass colonization of potato plants by beetle larvae. It is possible to leave on the processed site in 5 days.
Danger of the drug
Clotiamet is not phytotoxic. For a person has a hazard class - 3, i.e., the degree of danger is moderate. The same is true for mammals. For some fish it can be a certain hazard. Moderately dangerous for birds. For bees and bumblebees, Clotimet is extremely dangerous. It causes the destruction of colonies of bees. Because of this, it was even forbidden to apply the EU. Compared with the drug DDT, which is well-known and banned in many countries, is popularly known as dust, clotianidine-based preparations are more than 7,000 times more toxic to bees.
Attention! When complying with dosage and personal safety measures, harm to humans from Clotiamet is minimal.
