Description
Technical field
The invention belongs to insecticide preparing technical field, be specifically related to a kind of plant insecticide, preparation method and application thereof.
Background technology
Current control pest all use chemical insecticide mostly, along with the raising of living standards of the people, require high, not only will eat, and will eat health agricultural product quality.The Pesticide Residue that high malicious chemical pesticide causes more and more becomes the focus of social concerns.High-toxic pesticide is the core and the key that affect agricultural product quality and safety, not only affects agricultural product quality, directly endangers the healthy of the people, also affects increasing peasant income.Because the toxicity of high-toxic pesticide is large, the event of person poultry poisoning was caused to happen occasionally in the past.Very big on the impact of women and children, the children that teratogenesis is disabled are a lot.In addition, along with the protective awareness of countries in the world to environment for human survival and natural, ecological strengthens day by day, high malicious high residue insecticide will be restricted further.The quality safety of unreasonable use to agricultural product of agricultural chemicals constitutes a threat to, therefore, reduce Pesticide use particularly high-toxic pesticide use, to raising agricultural product quality and the market competitiveness, promote China's agricultural sustainable development, ensure the life security of broad masses of the people and very great meaning of building a harmonious society.
Because chemical pesticide is easy to the pesticide resistance causing insect; dosage is made in order to control efficiency well constantly increases; a lot of natural enemy and beneficial organism are murdered; and pollute us and to depend on for existence living environment; the more and more attention of Environmental protection; will be further strict to the Detecting Pesticide in agricultural product, therefore, greatly develop the direction that non-toxic and non-pollution high-efficiency plant source pesticide is Agrochemicals from now on.
Summary of the invention
The invention provides a kind of plant insecticide, preparation method and application thereof, use chemical pesticide control insect to cause the problem such as pest resistance to insecticide and contaminated environment to solve, plant insecticide composition of the present invention is nontoxic, noresidue, nuisanceless, environmental protection, can not bring environmental pollution; Plant insecticide of the present invention can effectively prevent and treat the plant insects such as yellow spider, arrowhead scales, leaf roller, trypetid, and one time killing rate all reaches more than 95.41%, and does not have drug resistance.
