Research And Preparation Of The Combined Emulsifiable Concentrate Of 7.1% Methoxyfenozide And Emamectin Benzoate

With the greater increasing investment risks in synthesize and production of novel pesticides, the longer market period and the more rapid development of pest resistance, the supply of efficient pesticides appear to be in great shorter. The rational combination among different pesticides play an important role in the following aspects: pest resistance control, improving control effect, decreasing the cost, a good harvest, prolonged application longevity of pesticides and lesser environment pollution.Methoxyfenozide belongs to the diacylhydrazine class of insect growth regulators, and it is effective for the control of most Lepidoptera pest, however it is safe for others orders pest such as Coleoptera, Homoptera, and so on. The test results of lab and field suggested: It is highly effective to Lepidoptera, and not harmful to insects of other orders such as bee, which is helpful to integrated pest management.Emamectin benzoate is synthesized from avermectin, which is derived from the antibiotic-producing actinomycetes Streptomyces avermictilis. It possesses many characteristics of biopesticide such as high efficiency, low toxicity, and low residue. At very low dosage, emamectin benzoate has high efficiency to Lepidoptera pest larvae and mites, and it is safe to beneficial insect, which is important to integrated pest management and has been considered as a substitute product for toxic and high residue pesticide.The two pesticides above have prominent advangtages. Meanwhile, methoxyfenozide is still in patent protection stage and there are no related combination products at home and abroad. So there is an excellent potential combination foreground of two pesticides. 7.1% methoxyfenozide~emamectin benzoate EC was selected through the optimum of various components with orthogonal design on the basis of optimal ratio of methoxyfenozide and emamectin benzoate, and these could supply some technical bases for further methoxyfenozide application. The main research methods and results could be summarized as follows:1 Screening of the optimal single pesticide...
