The plant louse is insects who most often attack cabbage. As wreckers usually lodge the whole colonies, it is necessary to take measures against them as soon as possible. If not to perform work in time, then it is possible to lose part, and even all harvest.
The plant louse is such wrecker whose appearance it is easier to prevent, than to get rid of it. Not all methods and means help to destroy insects from plants so that at the same time not to affect negatively vegetables. No, there are of course some national methods which not bad cope with plant louse, however it is not necessary to speak about elimination.
That the plant louse has not captivated cabbage (or any other) bed, first of all it is worth thinking of prevention methods. Cabbage it is impossible to put more than two seasons in a row on the same bed, but if it is not possible to allocate new bed for cabbage, then it is necessary to prepare old properly. Since fall it is necessary to destroy cabbage pokers, to dig over soil (it is desirable with entering into it of tomato tops of vegetable).
That the plant louse did not lodge on cabbage, on perimeter of bed it is necessary to plant tomatoes, marigold, calendula, fennel, celery or carrots. The plant louse does not love smell of these plants, and here their enemies - ladybugs and lacewings, these aromas and attract. It is worth remembering that where in large numbers there are settlements of ladybugs and lacewings - the plant louse does not take root.
If nevertheless the plant louse attacked cabbage, but insects on plants are visible in single copies, then in this case it is possible to fight with them manually. For this purpose it is required to put on gloves and to accurately crush insects on leaves. After the procedure the cabbage should provide ""warm shower"" to wash away all dirt from leaves.
If the plant louse on plants has created impressive colonies then stronger artillery is required. For spraying of saplings it is possible to use as self-made infusions, and to buy special industrial medicines. From self-made has perfectly proved cindery and soap solution (500 grams of ashes and 50 grams of laundry soap on 10 liters of water), from industrial - ""Kemifos"", Fury, ""Iskra-M"" and others.
Well and finally it is worth reminding that it is necessary to process cabbage from plant louse in dry weather, trying it is abundant to moisten in infusion or medicine all leaves. Usually three-five procedures are enough that wreckers have disappeared, but in certain cases (especially if there is rainy weather therefore medicines are washed away from leaves), also more than seven-ten times are required to repeat works.
