The invention belongs to a kind of insecticide, relate in particular to a kind of wettable plant insecticide pulvis.

Along with being on the increase of world population, the demand of industrial development, various countries are to agricultural product, especially the demand of cotton, grain constantly increases, and the soil falls sharply and is threatening the supply of agricultural product, in order to improve the per unit area yield of crops, except that applying fertilizer, kill the crop pests important process that is absolutely necessary.At present, be used to prevent and treat various insects of crops and evil bacterium thereof, mostly use chemical pesticide, according to the civilian introduction of second edition in " Chinese patent newspaper " on June 2nd, 1993 " development Overview of pesticide industry and patent situation ": nineteen ninety China's Pesticidal products account for the second place of the world, produce 156 kinds of pesticide species, wherein insecticide is 59 kinds, 9 kinds of miticides, 3 kinds of fumigant, 7 kinds of rodenticides, 39 kinds in bactericide, 33 kinds of weed killer herbicides, 6 kinds of plant growth regulator.These agricultural chemicals overwhelming majority belong to chemicals, chemical agents such as the Methomyl that uses as the cotton grower, decis, beta-cypermethrin, nuvacron, Rogor, phoxim, these chemical pesticides make damage by disease and insect have pesticide resistance for a long time, when spraying insecticide, the concentration of agricultural chemicals rises year by year, and the thing followed is seriously to have polluted environment, water resource and crops itself, this has not only destroyed the ecological balance, has also endangered people and animals' health and safety simultaneously.According to United Nations Environment Programme's statistics, the whole world has 2,000,000 people that acute pesticide poisoning takes place every year, wherein has 40,000 people to die.

Above-mentioned shortcoming in view of the chemical pesticide existence, numerous scientific research personnel begin one's study, and the extraction effective ingredient prepares insecticide from plant, as a company of Fla. from a kind of tropical plants---make insecticide if extract a kind of toxin the seed of chinaberry, can prevent and treat effectively tiny white fly and other insect more than 100 kinds, but the source of this insecticide is subjected to very big restriction, and output is extremely low.

It is extensive that goal of the invention of the present invention provides a kind of raw material sources, free of contamination wettable plant insecticide pulvis.

Its insecticidal mechanism of natural botanical insecticide provided by the invention is to utilize natural plants and cultivated plant to obtain separately active substance, mend each other and use, after mixing, the effect of insect intoxicating is strengthened, the intoxicating effect is to suppress the insect breathing, or adhering to by acetylcholinergic receptor, make the insect nervous system impaired, or the calcium that invests on the sarcoplasmic reticulum poisons by making muscle, and cause calcium ion to enter cell and cause death rapidly.The present invention is comprehensive to the insect fragmentation effect, can reach effectively to tag stomach toxicity and repellent action.

Plant insecticide pulvis of the present invention, the percentage by weight of each component is composed as follows:

Thunder God is risen 8-25% sweet wormwood 2-10%

Tobacco 5-25% Chinese honey locust 2-10%

China tree 5-30% hemlock 1-15%
