摘要:
为研究桃树生长季主要病虫害全程生物农药防治方案,2014-2015年对桃树主要病虫害,如蚜虫、红蜘蛛、褐腐病、梨小食心虫和桃小食心虫进行全程生物农药防治。休眠期使用矿物农药石硫合剂和波尔多液,生长季选择生物农药组合,包括苦参碱、藜芦碱、除虫菊素、枯草芽孢杆菌、苏云金杆菌和小檗碱,同时联用性诱剂、植物调节蛋白。结果表明,全程生物农药防控对梨小食心虫、桃小食心虫、褐腐病、蚜虫和红蜘蛛的防效分别为83.9%、78.1%、77.8%、76.7%和72.6%,各种防效等同或高于化学农药。生物农药全程防控的桃树长势强,未出现任何药害。生长季全程使用生物农药联合性诱剂,同时用植物调节蛋白增强桃树抗性,可有效控制桃褐腐病、蚜虫、红蜘蛛、桃小食心虫和梨小食心虫,由此构建了桃树主要病虫害防控集成体系。

Abstract:
Field trials were conducted to evaluate the efficacy of biopesticides?on disease and pest control in peach orchard during the growing seasons of 2014 and 2015. To control the main diseases and pests on peach trees, such as aphids, red mile, brown rot, peach fruit borer and oriental fruit moth, a lime sulphur with Bordeaux mixture was sprayed during the dormant season, while a mixture of biopesticides, including matrine, veratrine, pyrethrins, Bacillus subtilis, Bacillus thuringiensis and berberine, were sprayed during the growing season. In addition, sex lures and plant regulatory proteins were also used in field trials. Results showed that over the whole growing season the inhibition rates for oriental fruit moth, peach fruit borer, brown rot, aphids and red spider mites were 83.9%, 78.1%, 77.8%, 76.7% and 72.6%, respectively, which were similar or even higher than chemical pesticides. Notably, the peach trees grew vigorously, and no visual cytotoxicity was observed on the leaves or fruits. We thus conclude that oriental fruit moth, peach fruit borer, brown rot, aphids and red spider mites can be well controlled by the combination of biopesticides with sex lures and plant regulatory proteins. Overall, this study developed an integrated control system of biopesticides for whole course management of peach diseases and pests.
Key words:  biopesticides  peach  brown rot  pests  whole course management
