摘　　要：[目的]更好地防治板栗膏药病。[方法]以清水为对照,研究小雨天、晴天施用90%增效柴油乳剂和石硫合剂对板栗膏药病的防治效果。[结果]晴天施药后30 d,90%增效柴油乳剂和石硫合剂的防效分别为93.93%、78.12%,药后60 d的防效分别为84.60%、72.44%;小雨天施药后30 d,90%增效柴油乳剂和石硫合剂的防效分别为96.50%、88.03%,药后60 d的防效分别为87.51%7、5.29%。无论是晴天还是小雨天气施药,90%增效柴油乳剂对板栗膏药病的防治效果都优于石硫合剂,且差异显著。同种药剂在不同天气施用防效有显著差异。[结论]90%增效柴油乳剂和石硫合剂小雨天施用的防效高于晴天施用的防效。[ Objective] The aim of the research was to prevent and control chestnut plaster disease better. [ Method] With clean water as CK, the control effect of applying 90% synergistic diesel oil emulsion （SDOE） and llme sulphur synthelic solution （LSSS） in a rainy day and a sunny day against chestnut plaster disease were studied. [ Result] When the pesticides were applied in a sunny day, the control efficacy of 90% SDOE and LSSS were 93.93% and 78.12% resp. after 30 d and that were 84.60% and 72.44% resp. after 60 d. When the pesticides were applied in a rainy day, the control efficacy of 90% SDOE and LSSS were 96.50% and 88.03 % resp. after 30 d and that were 87.51% and 75.29% resp. after 60 d. Whether the pesticides were applied in a sunny day or a rainy day, the control effect of 90% SDOE against chestnut plaster disease was better than that of LSSS with significant difference. The control effect of the same kind of pesticide applied under different weather conditions had significant difference. [ Conclusion] The control efficacy of 90% SDOE and LSSS that were applied in a rainy day were higher than that in a sunny day.
