Effect of Pesticide Synergist Jiexiaoli on Control of Potato Late Blight by Fungicide
摘要
Abstract
[Objective]In view of the problems in potato late blight control caused by excessive application of pesticides,such as pesticide residues,environmental pollution and increased resistance to diseases,reducing dose and increasing effect test of application of pesticide synergist Jiexiaoli were conducted.[Method]Jiexiaoli and fungicide were mixed and 18 combination treatments were formed.A1B1C1 treatment(application of fungicide with interval of 7 days,no Jiexiaoli,and no reduction of fungicide)was used as control.The effects of reducing dose and increasing effect of fungicides applied by each combination treatment on potato late blight were compared.[Result]Among the combined treatments,A1B3C1 treatment(application with interval of 7 days,adding 10%Jiexiaoli and no reduction of fungicide)has the best control effect and the highest yield.Compared with the control group,the relative control effect was 37.47%,the yield was 24 900 kg/hm2,the increased yield percentage was 38.94%,and the large-medium size potato rate was 79.17%.The relative control efficiency of A2B3C1 treatment(application with interval of 10 days,adding 10%Jiexiaoli and no reduction of fungicide)was 28.36%,and the yield ranked the second,with an increased yield percentage of 37.32%and large-medium size potato rate of 69.20%.The relative control efficiency of A2B2C2 treatment(application with interval of 10 days,adding 5%Jiexiaoli and reducing the amount of fungicide by 10%)was 35.55%,the yield was the third,the increased yield percentage was 3.75%,and the large-medium size potato rate was 52.33%.[Conclusion]When the same dose of fungicide was applied,adding 10%of Jiexiaoli could improve the control effect of late blight and the rate of large and medium-size potato,and significantly increase the yield.In the case of reducing the amount of fungicide by 10%and adding the dosage of 5%Jiexiaoli,it could still significantly improve the relative control efficiency of late blight and slightly increase yield.关键词
