Abstract

The invention discloses a composite insecticide special for fruit trees. The composite insecticide is prepared from the following components: 10 parts of methoxyfenozide, 5-15 parts of oxymatrine, 20-30 parts of garlic, 30-40 parts of pyrethrum, 2-6 parts of terpineol and 10-20 parts of Chinese soapberry fruit. The invention also discloses a preparation method for the composite insecticide special for the fruit trees. Compared with the prior art, the composite insecticide special for the fruit trees is harmless to a human body and livestock; no pesticide hazard is generated to crops, pesticide residues are avoided, and the environment cannot be polluted; the composite insecticide has the characteristics of stable medicine, good pesticide effect and long lasting period. A few of organic synthesized substances are added into natural harmless substances serving as main raw materials; therefore, on the basis of enhancing the pesticide effect, the possibility of drug resistance of pests can be reduced, and the environment pollution is alleviated.

Description

One planting fruit-trees specific complex insecticide and preparation method thereof

Technical field

The present invention relates to a kind of insecticide, be specifically related to a kind of high efficiency composition insecticide that contains organic synthesis thing and natural extract, be applied to agriculture field.

Background technology

Insecticide, is mainly used in preventing and treating the medicine of pest and urban health insect. use historical long-range, consumption is large, wide in variety.At twentieth century, agriculture develops rapidly, and insecticide makes farm output rise higher.

Existing fruit tree insecticide, conventional simple artificial synthetic organic materials matter, although this insecticides drug effect is high, it uses for a long time, can make insect produce drug resistance, thereby the effect of losing, and its residual hazard phase is long, a large amount of agricultural chemicals evaporate in air, flow in water body, sedimentation is gathered in soil, pollute farming animals fishing fruit product, and transfer in human body by the enrichment of food chain, have a strong impact on crop growth environment and human and livestock health.At present, although the insecticide of many natural nuisance-frees is continually developed out, its insecticidal effect is not ideal enough.Therefore, how taking into account insecticide drug effect and prevent medicament residue contaminated environment, is current agriculture urgent problem.

Summary of the invention

Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a planting fruit-trees specific complex insecticide.

Technical scheme: for achieving the above object, a planting fruit-trees specific complex insecticide provided by the invention, it is mainly made by following component:

10 parts of methoxyfenozides, oxymatrine 5-15 part, garlic 20-30 part, Dalmatian chrysanthemum 30-40 part, terpineol 2-6 part, the fruit 10-20 part of washing one's hands.

As preferably, described fruit tree specific complex insecticide is mainly made by following component:

10 parts of methoxyfenozides, oxymatrine 8-12 part, garlic 22-28 part, Dalmatian chrysanthemum 32-38 part, terpineol 3-5 part, the fruit 12-18 part of washing one's hands.

Preferred as another kind, in weight portion, the concentration of described methoxyfenozide in described insecticide is (2-8) %.

The present invention also provides described fruit tree specific complex method for producing insecticide, and it mainly comprises the following steps:

(1) garlic, Dalmatian chrysanthemum and the fruit of washing one's hands are cleaned, are dried, pulverize, and add the water of 6-10 times of volume, extract 1-3 time, and each 1-3 hour, merges extract, the liquid extract that while being concentrated into 30 DEG C, relative density is 1.05-1.10;

(2) oxymatrine is dissolved with pure water, obtain Oxymatrine aqueous slkali;

(3) by above-mentioned liquid extract, Oxymatrine aqueous slkali and methoxyfenozide, terpineol, make liquid preparation according to conventional method.

As preferably, described liquid preparation is supensoid agent, emulsion, water dispersant or microemulsion.

Beneficial effect: the present invention is with respect to prior art, and the fruit tree specific complex insecticide of gained, to person poultry harmless, does not produce poisoning to crops, and non agricultural chemical residuum is free from environmental pollution, has medicine stable, strong drug action, the feature that the lasting period is long.Taking natural nuisance-free material as main, add a small amount of organic synthesis material, improving on the basis of drug effect, can reduce the possibility of insect generation drug resistance, reduce environmental pollution.
