Composition containing methylamine-avermetins-benzote

Abstract

The invention relates to a composition containing methylamine-avermetins-benzote, and belongs to the technical field of pesticides. The composition is made by compounding the methylamine-avermetins-benzote, other active ingredients (at least one of pyriproxyfen and pymetrozine) and various common carriers and auxiliary agents, wherein, corresponding to one part of the methylamine-avermetins-benzote by weight, a feasible mixing range of other active ingredients is as follows: 0.5-19 parts of the pyriproxyfen by weight and 3-50 parts of the pymetrozine by weight. The composition can be used for control of a plurality of agricultural and horticultural pests of cotton, paddy rice, vegetables and the like (e.g., control of sweetpotato whitefly, common thrips, aphides, whitefly, jassid, paddy rice hopper, paddy leaf roller, asiatic paddy borer, yellow paddy borer, paddy weevil and diamond back moth), has significant synergistic action and broad insecticidal spectrum, and can effectively overcome or delay generation of resistance of pests against various active ingredients, and obtain significant control effect.

Description

technical field [0001] The invention relates to a compound composition containing emamectin benzoate, belonging to the technical field of pesticides. Background technique [0002] Emamectin benzoate (abbreviation: emamectin benzoate) [0003] English common name: emamectin benzoate [0004] Chemical name: 4″-deoxy-4″-epi-methylamino-abamectin benzoate [0005] Molecular formula, molecular weight: B 1a :C 49 h 75 NO 13 ·C 7 h 6 o 2 (R=1008.26) [0006] B 1b :C 48 h 73 NO 13 ·C 7 h 6 o 2 (R=994.23) [0007] Emamectin benzoate is a new high-efficiency semi-synthetic antibiotic insecticide and acaricide, which has the characteristics of ultra-high efficiency, low toxicity, low residue, and pollution-free biological pesticides. It has incomparable activity against many pests than other pesticides (such as abamectin), especially for Lepidoptera, such as red-banded leaf moth, aphid armyworm, cotton bollworm, tobacco hornworm, diamondback moth, soyb...

AI Technical Summary

Problems solved by technology

[0008] In recent years, due to the large and frequent use of emamectin benzoate in agricultural production, various pests and mites have developed resistance to emamectin benzoate to varying degrees, which seriously affects the control effect on target pests. In order to overcome or delay resistance The production of harmful insects and mites is effectively killed. In practical applications, emamectin benzoate is often mixed with other insecticidal active ingredients, but the existing technology cannot curb the development of pest resistance in agriculture and horticulture so as to achieve impressive results. Satisfactory effect

[0009] Invention patent CN200710020941.1 discloses the active composition of pymetrozine and emamectin benzoate in the description, but the example combination disclosed in the text only shows a simple additive effect

Another example is another invention patent, CN200410066225.3, which discloses a combination of emamectin benzoate and pyriproxyfen as active ingredients in the specification, and the preparations with the proportions described in the document are not satisfactory in practical applications.
