Proved by a great number of indoor and outdoor experiments, The composition disclosed by the invention has the advantages that a remarkable synergistic effect is achieved after HNPC-A8008 and abamectin are mixed, so that the application field of HNPC-A8008 is widened in actual application, the pesticide-resistant risks of pests to abamectin are reduced, and the aims of taking a combined effect on the pests on multiple aspects, widening the prevented and controlled object range, improving the preventing and controlling effects, effectively preventing and controlling lepidoptera and homopteran pests on vegetables, rice, fruit trees and flower crops, and meanwhile reducing the dosage of a pesticide in a field, agricultural cost and environment pollution caused by the pesticide are achieved.
Description
Technical field
The present invention relates to a kind of Pesticidal combination; contained active ingredient is (E)-5-(3-chlorallyl) amino-1-(2; 6-dichlor-4-trifluoromethyl) phenyl-4-trifluoromethyl sulfinyl pyrazole-3-nitrile (test code number is HNPC-A8008) and Avermectin, for preventing and treating Lepidoptera and homoptera pest.
Background technology
Chemical name is (E)-5-(3-chlorallyl) amino-1-(2; 6-dichlor-4-trifluoromethyl) compound (test code number is HNPC-A8008) of phenyl-4-trifluoromethyl sulfinyl pyrazole-3-nitrile; that Hunan Chemical Research Institute is in order to reduce the fat-soluble of ethiprole medicament; by the new pyrazole compound with insecticidal activity of modifying for chemical structure design and synthesis, new chemical constitution improves the adverse side effect of this compounds to non-target organism.Formula 1 be shown in the chemical structural formula of HNPC-A8008.
HNPC-A8008 can be used for the control of the various crop insects such as paddy rice, vegetables, cotton, beet, as beet armyworm, prodenia litura, striped rice borer, paddy stem borer, rice leaf roller, cabbage caterpillar, aphid etc., its mode of action is based on stomach toxicity, there is certain contact toxicity, systemic activity is more weak, and quick-acting is good; This medicament is mainly used in numerous coleopteran pest control such as paddy rice, fruit tree, vegetables.
Avermectin (abamectin, A) is the natural products be separated from edaphon, is a kind of farm antibiotics, and its main mode of action is tagged, and stomach toxicity, penetration is strong.It is a kind of macrolide disaccharide compounds.Formula 2 be shown in Avermectin chemical structural formula.
Avermectin has insects and mites tags and stomach poison function have faint fumigation action, without systemic action.Its mechanism of action and general insecticide disturb neurophysiology movable unlike it, stimulate release r-aminobutyric acid, and r-aminobutyric acid has inhibitory action to arthropodan nerve conduction, if namely there is paralysis symptom after becoming mite to contact with medicament with larva with insect in mite class, inertia does not take food, dead after 2-4 days.But it has very strong osmosis to blade, subepidermal insect can be killed, and the longevity of residure is long.Simultaneously because consumption is little, easily degrade, thus environmentally safe, noresidue.To plant height safety.In a word, Avermectin is a kind of efficient, high selection, green, environment-friendly type, biological source insecticide.Avermectin has good effect for preventing and treating the insects such as striped rice borer, paddy stem borer, rice leaf roller, cotton bollworm, smaller green leaf hopper in recent years, but quick-acting is slightly poor, and Long-Time Service, insect creates resistance to it.
The two uses with proper proportion mixture, can from many aspects to insect synergy, and reaching just can the effective object that causes harm of Control pests with lower dosage.Dosage reduces simultaneously, also alleviates the pressure of chemical pesticide to environment, can also delay the generation of pest resistance to insecticide.Therefore, Avermectin and HNPC-A8008 mixture are worthy of popularization in agricultural production.
Not yet there is the report of HNPC-A8008 and Avermectin mixture at present.
