摘　　要：本试验以炭疽病常用防治药剂30%苯醚甲环唑悬乳剂和45%咪鲜胺水乳剂单剂为对照,研究了20%苯醚甲环唑·咪鲜胺水乳剂对枸杞炭疽病的田间防病效果。结果表明,20%苯醚甲环唑·咪鲜胺水乳剂100mg/kg、133.3mg/kg和200mg/kg 3个处理两次药后的防效分别为77.64%、81.87%和83.73%;20%苯醚甲环唑·咪鲜胺水乳剂133.3mg/kg处理的防效与对照药剂30%苯醚甲环唑悬乳剂75mg/kg和45%咪鲜胺水乳剂168.75mg/kg处理防效相当,表明20%苯醚甲环唑·咪鲜胺水乳剂对枸杞炭疽病具有较好的防治效果,对作物安全,可在生产中推广使用。In this study, 30% Difenoconazole SE and 45% Prochloraz EW as control, that the control effect of 20% Difenoconazole prochloraz EW agaist Chinese wolfberry anthracnose was studied on field. The results showed that the control effects of 20% Difenoconazole prochloraz EW with doses of 100mg/kg, 133.3mg/kg and 200mg/kg after two treatments were 77.64%, 81.87% and 83.73%, respectively. The control effect of 20%Difenoconazole prochloraz EW with 133.3mg/kg was equivalent to that of 30% difenoconazole SE with 75mg/kg and 45%prochloraz EW with 168.75mg/kg. It showed that 20% Difenoconazole prochloraz EW hadgood control effect on Chinese wolfberry anthracnose, safety for crops and could be popularized and used inproduction.
