Potatoes is the main food in Russia from autumn and in the spring, we store this vegetable for cooking. And of course it is very annoying when potatoes are not preserved due to the tuber-free left.
In general, harm to the potato area, the wire is perhaps little in which the Colorad beetle will give way. But about the colorado beetle they write a lot and say, and the wireman is not visible and not heard, they do not write anything about it in advertising, and not yet available and widespread preparations for combating it are practically not created.
And at this time the pest slowly makes his "black" case.
Nutcars, wires (lat. Elateridae) - family of beetles. Body length is usually 7-20 (sometimes up to 50) mm. About 10 thousand species, in Eurasia and America; In Russia, several hundred species are distributed almost everywhere.
The larvae (wires) damage the roots of many plants. The name was obtained in connection with the characteristic features of the structure and behavior.
From the bottom on the front breast there is a finger-shaped process, directed backwards, and in the middle breast, the recess corresponding to it. The beetle turned over on the back, removing the process from the excavation and resting it into its edge, after which it returns the process to the excavation with a click. As a result, clicking the beetle bounces. The beetle will continue clicking until it turns over to the abdominal surface and will not stand on his feet.
Damage caused by wires is huge. They destroy the swollen seeds, shoots, eat gentle roots and stems.
Many people know the cultivation of potatoes. Often fresh potatoes are permeated black strokes. This is the result of the "work" of the wire.
The strokes of the wire in potatoes are a real attack. It is much easier to throw away such a tuber, rather than try to clean it. However, it is even more wise - to prevent his damage.
1. In order not to give a wire carrier to spoil your harvest, lime regularly.
For this, as often as possible, it is necessary to add ash, lime and chalk to the ground. The best tool is considered the limestone (dolomite) flour. You need to make it just once every three or four years.
2. To preserve a healthy harvest, to reduce the number of pests on the household site, it is recommended to carry out the following activities: early spring - deep plowing or soil resistance, destroying weeds, especially crawling drinking; Place potatoes after peas and beans. Next to the gardening of potatoes should be a minimum of weeds with densely intertwined rhizomes.
It is better to use several methods to eliminate the pest at once. The treatment and control of the wire begins immediately as soon as the pest was found on the soil. The main measures of prevention and struggle at the initial stage is to jump the beds as in spring and late in the fall. Wire larvae will be upstairs and will be eaten by arriving birds. If possible, you need to remove larvae or dolls of beetles.
3. The wire is eating potatoes only due to the fact that he lacks moisture, so it is recommended to water the plot during a strong drought.
