[Controlling effects of plant extracts and pesticides on Myzus persicae and Lipaphis erysimi populations].
This paper studied the controlling effects of Xanthium sibiricum and Syngonium podophyllum ethanol extracts, mobile oil emulsion and 0.3% azadirachtin EC on Myzus persicae and Lipaphis erysimi populations both in laboratory and in field. The results showed that in laboratory, X. sibiricum extract was the key deterrent to Myzus persicae, while sprayed it with S. podophyllum extract and with petroleum spray oil or 0.3 % azadirachtin EC, the deterrent effect could be improved. As for pterigota Lipaphis erysimi, the extracts of the two plants were the main deterrents, and their interference effect was non-linear. In field, S. podophyllum extract had a stronger deterrent effect when sprayed independently. L. erysimi population could be successfully controlled by the mixtures of plant extracts and insecticides, with an efficiency of 95.7%. The best treatment against M. persicae population was X. sibiricum extract, with an efficiency of 87%, while S. podophyllum extract mixed with 0.3% azadirachtin EC, and X. sibiricum extract mixed with 0.3% azadirachtin EC had an efficiency of >80%.
