History of the distribution of the Colorado potato beetle

Before we begin to disassemble ways to combatColorado beetle, you need to understand the reason for its wide distribution. And it is largely due to the peculiarities of migration of this insect. Now it's hard to believe, but until 1949 in the USSR did not know grief under the name "Colorado beetle". And this despite the fact that this pest was already in full swing in Western Europe since the First World War. There are several versions of how the potato beetle hit the fields of the former USSR. According to one of them, the "colorades" penetrated from the territories of Poland and Hungary after the Second World War. According to another - a storm to the spread of the pest was a storm in the Baltic Sea, which hit the shores of the Baltic countries. During the Cold War, the popular version was even that the Colorado beetle is a sabotage project by the American special services, who planned to undermine the agricultural sector of the Union. In general, however, most historians tend to believe that wars contributed to the mass dominance of these insects. The following fact is in support of this version. It is known that the first penetration of Colorado beetles into the USA from Mexico occurred during the Civil War. Being inconspicuous and not particularly harmful insects in their homeland (in Mexico, the "colorades" ate mainly leaves of wild tobacco), having got to the States, striped beetles began massively destroying potato fields. After one of the most powerful destruction of potato plantations in the state of Colorado, they got their name.

Effective means from the Colorado potato beetle

Unfortunately, despite everythinghigh-tech achievements of modern science, scientists have not yet invented a method that helps to permanently sow potato crops from baleen invaders. Of course, at the moment there are a lot of effective insecticides, which will greatly facilitate the life of truck farmers. But, unfortunately, even the most recent and progressive means of striped beetles adapt very quickly. Therefore, the most effective method of combating the Colorado beetle is a complex approach, consisting of manual assembly, chemical processing and folk methods. Next, let's talk about each of them in more detail.

Remedy for Colorado beetle: manual collection

One of the most energy-intensive, but at the same timeand the most effective is the manual collection of Colorado beetles. It allows one to get rid of both adults and their larvae and egg laying with equal success. As a rule, potato beetles are collected in small containers filled with kerosene or solar oil. It is believed that only in these liquids insects perish. Adult individuals and formed larvae of different stages are removed from the leaves and sent to a special jar. Oviposition, which the females place under the leaves of the plant, are removed along with the damaged leaf. After the collection is over, the insects are burned or crushed. High efficiency this method shows with regular use.

In addition to manual collection, it is very effective in combatingpotato beetle use and folk remedies. For example, the fact is known that Colorado beetles are very sensitive to sharp smells. Moreover, they do not tolerate them chronically and therefore avoid the source itself. To this kind of scaring fragrances, you can include onion, garlic, dill, calendula, violets. Therefore, enterprising farmers planting onion husks or small pieces of onions directly in the hole with potatoes when planting. Thus, "two hares" are killed immediately: rotten onions are a good fertilizer for potatoes, and its scent repels the pest. In addition, it is also possible to plant shrubs of calendula or violets between potato rows or around the perimeter of the site. In the latter case, one must be sure that there are no Colorado beetles remaining in the vegetable garden after hibernation. To do this, with the first warm spring days, the following operation should be carried out in the vegetable garden: soak potato tubers in urea or chemical poison, cut into several parts and arrange a ready "treat" throughout the garden. The first rays of the sun, warming the earth, will wake the beetles after hibernation and they will crawl to the surface in search of food. Then it's up to the little one to collect the "catch" and finish off the Colorado beetles that have not had time to regale with your "culinary masterpiece".

Another effective folk method is ashes. Or rather, the sprinkling of plots with potatoes with wood ash. In some sources it is said that only birch ash delivers miraculously from harmful insects. But practice shows that potato beetles are sensitive to any wood ash.

The final stage in the struggle for a good harvestpotato is the treatment of plants with modern insecticides. Unfortunately, the Colorado beetle quickly adapts to a new poison and develops to it immunity, which is passed on to the next generation of insects. Therefore, experienced gardeners recommend alternating several types of insecticides during the processing of plants.

It is also important to know that all chemicalsfor processing potatoes from a pest are divided into 3 main groups: contact, systemic and biological. Insecticides of contact action do not penetrate deep into the plant and act solely on the insect when in direct contact with it. Such drugs are washed off with water and rain, so do not have a prolonged effect. More effective are the preparations of systemic action, which penetrate into the plant and destroy the pest.

Biological preparations contain spores of bacteria,which lead to the death of the Colorado potato beetle. This is the safest for humans and other insects category of drugs. About which group the insecticide belongs to can be recognized from the marks on the package.
