摘要
为了探讨种衣剂对水稻的安全性及对恶苗病的防治效果,研究了11%多.咪.福美双悬浮种衣剂药种比1∶40、1∶50、1∶60对水稻的安全性及对防治水稻恶苗病的效果。结果表明:对水稻出苗、秧苗生长及成熟期均无不良影响,对水稻安全,并且增产显著。秧苗移栽前在秧田对水稻恶苗病的平均防治效果分别为90.53%～95.88%,本田抽穗前平均防治效果分别为88.70%～96.47%。适宜施药时期和用药量:在水稻浸种前,11%多.咪.福美双悬浮种衣剂按药种比1∶(50～60)的比例进行种子包衣。
In order to explore the security and control effect of seed coating on rice hakanae disease, the effect of 11 % Carbendazim. Prochloraz. Thiram FSC and seeds mixed with proportion of 1 ： 40,1 ： 50,1：60 on controlling bakanae disease and rice security were studied. The results showed that they had no adverse effect on rice seedling emergence,seedling growth and maturity, they were safe to rice and could make the yield increasing remarkable. The average effects to prevent rice bakanae disease before transplanting in seedling were 90.53- 95. 88% ,the average effects before heading in field were 88. 70% -96.47%. Appropriate application period and dosage：Before seed soaking, 11% Carbendazim. Prochloraz.Thiram FSC and seeds mixed with proportion of l： （50-60）.
