Abstract

The invention discloses a 0.3% matrine compounded agent, belonging to plant source biological pesticide, characterized by using a natural plant as a main body, comprising more than five Chinese medicinal plants, prepared by technical extraction of soaking, cooking and filtering and the like. The plant source material and the weight percent are as follow: kuhseng 35-45%, oriental biter weed 10-15%, Chinaberry seed 12-18%, kusnezoff mondshood 10-15%, agrimony 8-13%, nicotiniana rustica 11-16%, also added with radix stemonae stemona 2-5%, triperygium wilfordii 2-5%, the extracts are matched with diluted emulsifying agent, with marked pest prevention effect. The invention is used as a novel highly active biological pesticide, with wide applying foreground.

Description

0.3% matrine compound agent

Technical field

The present invention relates to a kind of biopesticide, particularly based on new and effective 0.3% matrine compound agent of shrubby sophora extract.

Background technology

For a long time, agricultural sustainable development in traditional chemical pesticide serious threat, and to the healthy toxic and side effect that shows of people, residual and " three cause " is more and more obvious, and chemical pesticide is replaced by biopesticide and the efficient chemical pesticide of low toxicity just gradually.Botanical pesticide is " integrated control ", " medicine is used more ", economy, safety, comparatively ideal biopesticide, and development prospect is wide.In recent years, domestic continually develop out by the natural plant raw material extract, formulated biopesticide, also relevant for the report of the insecticide that contains matrine.But in the existing botanical biological pesticide, contained active substance is more single, and complementarity is not strong, plant resource raw material proportioning is reasonable inadequately, and active matter purity (content) is not high in the raw material, causes the preventive effect of such biopesticide lower, it is slower to knock down quick-acting, influences the effect of its pest control.

Summary of the invention

The object of the present invention is to provide a kind of both pollution-free, noresidue, safe and reliable, can improve preventive effect again, strengthen and knock down quick-acting, have 0.3% matrine compound agent of remarkable pest control effect.

Technical scheme of the present invention is: 0.3% matrine compound agent forms by the natural medicinal plant extract is composite, improvements are that described medicinal plant is based on kuh-seng, comprise southern tongue rattan, chinaberry, radix aconiti agrestis, hairyvein agrimony, Nicotiniana rustica multiple components, the weight percent content of each medicinal plant is: kuh-seng 35%～45%; South tongue rattan 10%～15%; Chinaberry 12%～18%; Radix aconiti agrestis 10%～15%; Hairyvein agrimony 8%～13%; Nicotiniana rustica 11%～16%.

Further scheme is: increase the tuber of stemona, thunder godvine in the described medicinal plant, its weight percent content is: hundred steps 2%～5%; Thunder godvine 2%～5%.This composite dose is cooperated with emulsifier after the dilution by the extract of described medicinal plant and to form, and the weight proportion of extract and emulsifier is 1: (8～12).It is 50%～55% ethanol dilution that described emulsifier adds concentration, and the thinner ratio of emulsifier and ethanol (weight) is 1: (2.5～3).

Matrine compound agent of the present invention is based on pure natural medicinal plant kuh-seng, compound more than five kinds traditional Chinese medicine by technologies such as immersion, boiling, filtration extract, formulated agricultural insecticide, adopt raw material to be all natural plants, pollution-free, noresidue, safe and reliable; Raw materials used wide in variety, proportioning determines after repetition test, and is scientific and reasonable, contains multiple different activities material, with strong complementarity, can suppress nuisance and reach in growth, growth, the breeding of different phase and prevent and treat purpose.In this insecticide, alkaloid is matrine and nicotine, matrine content 〉=0.3% wherein, when soup with after insect contacts, enter in the body by insect skin and oral cavity, suppress respiratory of insect, anesthesia insect nervous system is destroyed the insect digestive system, behind the insect contact medicine, hit the speed of killing generally in 10～30 minutes, even if can not be dead, also will lose appetite, the egg production capacity forfeiture, be in narcosis, irreproducible offspring, crop is after this medicine sprays, and insect-repellent is strong, insect dare not be close, has very strong comprehensive effectiveness.This insecticide confirms that preparation is functional, and quick-acting and lasting effect are preferably arranged, and crop safety is not had poisoning through agriculture chemical examination institution, Shanxi Province, agriculture chemical examination institution, Beijing in to aphid on grain and the vegetables and cabbage caterpillar experiment; To field medicine effect test, killing rate reaches more than 93% through Institute of Plant Protection, academy of agricultural sciences, Shaanxi Province.

Embodiment

Further specify the present invention below by embodiment.

Example one: get and clean kuh-seng 42kg, southern tongue rattan 10kg, chinaberry 16kg, radix aconiti agrestis 12kg, hairyvein agrimony 8kg, the Nicotiniana rustica 12kg dry, pulverize respectively, through immersion, boiling, filtration, concentrate, precipitation, filter, return and step such as heat up in a steamer, collect mother liquor; Be that 52% ethanol was by weight 1: 3 mixed diluting with emulsifier and concentration; Again mother liquor and the emulsifier of collecting after the dilution was mixed with 0.3% matrine compound agent by weight 1: 8.

Example two: get and clean kuh-seng 36kg, southern tongue rattan 12kg, chinaberry 12kg, radix aconiti agrestis 10kg, hairyvein agrimony 12kg, the Nicotiniana rustica 13kg that dries, tuber of stemona 2kg, thunder godvine 3kg, step in example one, collect mother liquor, emulsifier and concentration 55% ethanol by weight 1: 2.5 mixed diluting, were mixed with 0.3% matrine compound agent with the emulsifier after the mother liquor collected and the dilution again by weight 1: 10.
