Description

Composition pesticide

Technical field

The present invention relates to a kind of synergetic pesticide composition, particularly relate to a kind of synergetic pesticide composition that comprises emamectin-benzoate and butyl ether urea.

Background technology

Emamectin-benzoate (emamectin benzoate) (hereinafter to be referred as first dimension salt) is a kind of novel high-efficiency low-toxicity antibiotics Insecticidal and acaricidal agent.The main mode of action of this medicine is stomach poison function and has certain action of contace poison concurrently, its mechanism of action is to disturb the activity of insect neurophysiology, suppresses the trip of gamma-aminobutyric acid receptor chlorion, and blocking-up kinesitherapy nerve information is transmitted, make the kinesitherapy nerve paralysis, insect stops to get food and death.First dimension salt can be prevented and treated multiple lepidoptera pest, especially conventional pesticide is produced the insect preventive effect brilliance of resistance.

Butyl ether urea (diafenthiuron) has another name called methamidophos; main cover crop is fruit tree, vegetables, cotton, tea and ornamental plants etc.; aphid, aleyrodid, leafhopper there is high preventive effect; diamond-back moth, cabbage caterpillar and the grey noctuid that produces resistance there is special preventive effect; the two spotted spider mite that produces resistance, tarsonemid etc. there are high preventive effect, use the result to confirm that this medicine is very satisfied to the Plutella xylostella effect of those high anti-chrysanthemum ester cotten aphids, high anti-organic phosphor abroad.The butyl ether urea has splendid tagging and stomach poison function, though there is not systemic action, but the good penetration effect is arranged, the butyl ether urea has special mechanism of action, it can be considered a kind of lead compound of insecticide, under ultraviolet irradiation or in polypide under the help of mixed-functional oxidase, be decomposed into a kind of carbodiimides, this material has mitochondrial function in the interior nerve cell of the pest body of obstruction, influence its respiration and power conversion, make insect ossified, therefore, the butyl ether urea is to natural enemies security, to earthworm and birds safety too.

Though in Chinese patent application 200410002174.8, disclose the insecticide acaricide composition of Avermectin and butyl ether urea, still do not had the play-by-play of the mixture preparation of relevant first dimension salt and butyl ether urea at present.The inventor furthers investigate the mixture preparation of first dimension salt and butyl ether urea, the result finds that surprisingly the mixture preparation of first dimension salt and butyl ether urea not only has splendid synergistic effect, and has than the better potentiating pesticidal effect of the mixture preparation of Avermectin and butyl ether urea.

Based on above-mentioned unexpected the present invention that finds to have finished.
