Embodiment 1

[0042] Example 1: Killing effect of asvermectin on whitefly (bemisia tabaci).

[0043] Drugs for testing:

[0044] 92% abamectin (abamectin) (Zhejiang Qianjiang Biochemical Co., Ltd.);

[0045] 96% acetamiprid (acetamiprid) (Zhejiang Hisun Chemical Co., Ltd.);

[0046] 91% Milbemycin (Zhejiang Hisun Chemical Co., Ltd.);

[0047] 95% Tenvermectin A (Tenvermectin A) (Zhejiang Hisun Pharmaceutical Co., Ltd.).

[0048] Dissolve each original drug in DMF respectively, and prepare a solution of 10000 mg / L for subsequent use.

[0049] Leaf immersion liquid film method was used. Dilute various agents with tap water into 0.25mg / L, 0.5mg / L, 1.0mg / L, 2.5mg / L, 5.0mg / L, 10mg / L and 20mg / L of liquid medicine, pick fresh tomato leaves and put After soaking in the medicinal solution for 5 seconds, take it out, put it in the room to dry, and put 1 tomato leaf in each petri dish. Three repetitions were set up for each treatment, and the leaves were soaked in water, dried and placed in a pe...

Abstract

The invention relates to an application of tenvermectin A and / or tenvermectin B to control of harmful insects in agricultural and forestry crops. The tenvermectin A and / or the tenvermectin B has the control effect on the harmful insects such as Bemisiatabaci, Frankliniella occidentalis Pergande, Laodelphax striatellus, Nilaparvata lugens, Sogatella furcifera, rice leaf folder, rice stem borer, yellow stem borer and Coptotermes formosanus in agricultural and forestry crops, is low in toxicity and more environment-friendly and has good application prospect, wherein R is CH3 in the tenvermectin A and R is CH3CH2 in tenvermectin B.

Description

field of invention [0001] The invention relates to a new application of asvermectin A and / or asvermectin B in controlling harmful insects in agricultural and forestry crops. Background technique [0002] The 16-membered macrolide compound produced by Streptomyces has the characteristics of high activity and broad spectrum, and has been widely used in the control of pests and mites in agricultural and forestry plants. At the summary meeting of the highly toxic pesticide substitution demonstration project held in 2008, experts recommended 28 pesticide varieties such as abamectin as the fourth batch of 5 highly toxic pesticides (methamidophos, parathion) for seven major crop diseases and insect pests including rice , methyl parathion, monocrotophos and phosphamide), and announced 56 supporting technologies. Abamectin is a new type of antibiotics. It is a sixteen-membered macrolide compound with insecticidal, acaricidal and nematicidal activities first developed by Satoshi Omur...
