Control Efficiency Analysis of Ten Fungicide Treatments on Potato Late Blight
Control efficiency of ten fungicide treatments on potato late blight was determined in field experiment. The results showed that there were significant effects on control of potato late blight except Metalaxyl. The best fungicide treatments were Mandipropamid, Cyazofamid and Propamocarb-HCl + fluopicolide, then fol owed by Fluazinam, Famoxadone+cymoxanil, Matrine, Cymoxanil+mancozeb, Mancozeb, and Metalaxyl+mancozeb. Yields were increased from 11.11%to 45.66%as compared with the control. Tuber rotting percentage ranged from 2.94%to 12.33%. According to the disease progress curve, al of the ten fungicide treatments used in the early stage of disease development could achieve a significant control effect, and in the late stage, however, Mandipropamid, Cyazofamid and Propamocarb-HCl+fluopicolide were strongly recommended.
