粉锈宁1,200ppm处理玉米种,出苗比对照迟3天,出苗率低7.9％,对玉米苗有一定抑制作用,但拔节后玉米恢复正常生长,所有小区无一发病,对照区病株率15.2％。800ppm处理的玉米种籽,出苗比对照迟1天,出苗率低6.9％,病株率0—2.4％,防效高达94.6％以上。 用相当于玉米种子重量0.6％、0.4％、0.2％的粉锈宁处理:0.6％拌种的小区病株率平均为5.3％,防效为78.9％;0.4％拌种加0.2％药土盖种处理的小区,病株率为4.2％,防效为79.3％;0.2％药土盖种的小区病株率为8.2％,防效为64.9％。
Triadimefon 1,200ppm treated maize seedlings, emergence three days later than the control, the emergence rate of 7.9%, corn seedlings have a certain inhibitory effect, but after jointing corn normal growth, no incidence of all the communities, the control area diseased rate of 15.2%. Seed germination of 800ppm treated corn was 1 day later than the control, the emergence rate was 6.9%, the diseased plant rate was 0-2.4% and the control efficiency was as high as 94.6%. With the equivalent of corn seed weight 0.6%, 0.4%, 0.2% of the pink rust Ning treatment: 0.6% seed dressing plot of the district average rate of 5.3%, control effect was 78.9%; 0.4% seed dressing plus 0.2% Of the area, the diseased plant rate was 4.2%, the control effect was 79.3%; 0.2% soil cover plant community disease rate was 8.2%, control effect was 64.9%.
