Abstract

A synergistic pesticide combination is characterized by comprising the active ingredients including flubendiamide (A) and abamectin or emamectin benzoate (B) in a weight ratio of 100:1-1:10, preferably 30:1-10:1. The total weight percent of the two active ingredients in the combination is 5-60%. The dosage form of the combination is preferably one or more of wettable powders, suspending agent, micro-emulsion, aqueous emulsion or water dispersible granules. The combination of the invention can be used for controlling cnaphalocrocis medinalis and spodoptera exigua in agriculture.

Description

technical field [0001] The invention relates to a synergistic pesticide composition, in particular to an insecticide composition containing flubendiamide, the preparation of which can be used to control agricultural pests, especially rice leaf roller and beet armyworm. Background technique [0002] Rice leaf roller (Cnaphalocrocis medinalis) is a migratory rice pest, which causes white leaves of rice. It is sudden and widespread, causing serious decline in rice yield and quality. It is one of the main rice pests. For a long time, the control of rice leaf roller has mainly relied on insecticides such as methamidophos, monosultap, dimehypo, triazophos, and abamectin, among which methamidophos is a highly toxic pesticide that has been banned; Chongdan and Dimehypo have poor control effects on rice leaf rollers above the 2nd instar, and due to long-term use, rice leaf rollers have developed obvious resistance, and the control effect has decreased significantly; The activity of ...
