摘要
12 .5%禾果利对小麦纹枯病效果好 ,该农药与种子按 3 0 0～ 4 0 0 g/ 10 0kg拌种 ,病株率相对防效达到 93 .2 % ,千粒重增加 1.6～ 5.2g ;以 3 0 0g/hm2 在 2月下旬和 3月中旬喷雾两次 ,侵茎率相对防效达到 99.3 %～ 10 0 %。
The result of field experiments showed that 12.5%diniconazole had good control effects against wheat sheath blight(Rhizoctonia cerealis V.Hoeven& R.Solani Kühn).When 300～400g pesticide was stired together with every 100kg wheat seed,the control effect was 93.2% and the weight increase per 1000 seeds was 1.6～5.2g.Two sprays at the concentration of 300g/ha that were applied in late February and middle March had so excellent control effects that it was up to 99.3%～100%.
