Domain.
Background technology
Wild cabbage also known as cabbage, cabbage, cabbage, cabbage.It is one of the best vegetables of world health organisation recommendations,
Also it is known as natural " stomach dish ".Vitamin K1 contained by it and vitamin are not only resistant to stomach ulcer, protection and to repair stomach glutinous
Membrane tissue can also keep stomach cell mobilization vigorous, reduce the probability of lesion.Diamondback moth belongs to lepidoptera diamond-back moth section, is to cause harm
The worldwide important pests of brassicaceous vegetable, often cause catastrophic collapse to the production of brassicaceous vegetable.Chemical pesticide is
The main control measure of diamondback moth, the long-time service of a large amount of chemical insecticides and abuse cause its resistance level to be continuously improved, and resist
Property spectrum constantly expand, drug resistance is all almost produced to used insecticide, has not only seriously undermined current chemical insecticide
The control action to cause harm to it also results in using and abusing for chemical pesticide larger dose, it is residual to cause pesticide in agricultural product
A series of food and the environmental securities such as exceeded and environmental pollution are stayed, is become in China's brassicaceous vegetable production process urgently
One of main problem of solution.
