Abstract

The present invention is one kind of avermectin emulsion preparation with neem oil as synergist. The avermectin emulsion preparation is prepared with natural avermectin, stabilizer, penetrant, emulsifier, natural synergist neem oil and natural solvent in certain weight proportion, and through mixing and high speed stirring. The avermectin emulsion preparation has the reasonable combination of avermectin and nimbin as natural plant pesticides, so that it has high pesticidal efficiency, broad pesticidal spectrum, no pollution, no residue, less resistance, safety to human body, warm-blooded animal and natural pest enemy and lasting pesticidal effect.

Description

With the neem oil is the pyrethrin emulsion preparation of synergist

Technical field

The present invention relates to the pyrethrum element pesticide, specifically is the pyrethrin emulsion preparation of synergist with the neem oil.

Background technology

Natural pyrethrum (Pyrethrin) and nimbin (Azadirachtin) all are the biopesticides of pure natural, efficiently, wide spectrum, pollution-free, noresidue, be difficult for developing immunity to drugs, harmless and be its common feature to homoiothermy animals such as people and animals to pest natural enemy safety, but natural pyrethrum and nimbin also have characteristics separately.Natural pyrethrum is very fast to the speed of knocking down of insect, and is general only with 5-10 minute, and nimbin generally just can show later at 3 days the effect of insect.The insecticidal mechanism of pyrethrin has autotomy, stomach toxicity, avoids and keep away, and main is to tag, and penetrates into polypide by skin and pore, destroys central nervous system, and its paralysis is caused death.The insecticidal mechanism of nimbin has food refusal, avoid keep away, tag, stomach toxicity, interior suction and suppress insect growth growth effect.

Summary of the invention

The purpose of this invention is to provide a kind of lasting medicine, what have better insecticidal effect is the pyrethrin emulsion preparation of synergist with the neem oil.

Contain multiple desinsections such as nimbin, bitter principle in the neem oil (neem oil) and press down the worm composition, the present invention finds that through test neem oil has 0.5-5 synergistic effect doubly to pyrethrin.

The present invention is mixed by a certain percentage by natural pyrethrum, stabilizing agent, bleeding agent, emulsifier, natural synergic agent neem oil and pure natural solvent, the pyrethrin emulsion preparation that forms through high-speed stirred.Concrete compound method is: the content that takes by weighing 1%-10% is 50% natural pyrethrosin primary medicine, the stabilizing agent 2-6-BHT (BHT) that adds 0.2%-2%, the natural synergic agent neem oil that adds 1%-10%, add agricultural chemicals 5202 emulsifier 5%-10% and agricultural chemicals 2201 emulsifier 3%-6%, add water-soluble azone 0.5%-5%, add turpentine oil again, be diluted to total amount, be deployed into the cream preparation that contains the 0.5%-5% pyrethrin.

Advantage of the present invention is: 1, efficient, wide spectrum, pollution-free, noresidue, be difficult for developing immunity to drugs, harmless and to homoiothermy animals such as people and animals to pest natural enemy safety; 2, this cream preparation possessed autotomy, stomach toxicity simultaneously, avoid keep away, tag, food refusal, interior suction and suppress effect such as insect growth growth; 3, make pyrethrin combine lasting medicine to knocking down fast of insect with the chronic effect of nimbin to insect.
