Field trials of biopesticides for whole course management of peach diseases and pests
Field trials were conducted to evaluate the efficacy ofbiopesticides 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 ofbiopesticides for whole course management of peach diseases and pests.
