摘　　要：随着生态和绿色农业建设不断推进,环保型低毒生物农药被广泛研发与利用。针对水稻主要病虫害,本研究探讨了不同有效成分用量阿维菌素和井冈霉素混配剂(以下简称阿•井混配剂)在室内试验和田间试验对水稻主要病虫害的防治效果。结果表明:阿•井混配剂对毒杀水稻纹枯病菌、稻飞虱(白背飞虱和褐飞虱)、二化螟、三化螟、黑尾叶蝉有显著的增效作用。其增效作用可部分中和病原菌和害虫的抗药性,从而延长药剂的使用期。使用阿•井混配剂对稻纵卷叶螟和稻螟蛉的毒杀效果与单独使用阿维菌素时的毒杀效果相当。综上所述,生物农药阿维菌素和井冈霉素混配具有提高对水稻主要病虫害防控能力的潜力,并且属于绿色防治方法,值得大力推广应用。With the continuous advancement of ecological and green agricultural construction,environmentally friendly and low-toxicity biopesticides have been widely developed and utilized.This study investigated the control efficiencies of different active ingredient dosages of avermectin and jinggangmycin(A&J)mixture on major rice diseases and pests via both laboratory tests and field tests.The results revealed significant synergistic effects of the A&J mixture on killing Rhizoctonia solani Kühn,rice planthoppers(Sogatella furcifera and Nilaparvata lugens),Chilo suppressalis,Tryporyza incertulas and Nephotettix bipunctatus.This synergism can partially neutralize the resistance of pathogenic fungus and pests,thereby prolonging the duration of pesticide use.The toxic effects of the A&J mixture on Cnaphalocrocis medinalis and Naranga aenescens were found to be similar to those of avermectin alone.Therefore,the A&J mixture has the potential to improve the prevention and control capacities to major rice diseases and pests,and it is a green prevention and control method that is worthy of widespread promotion and application.
