摘  要:
[目的]筛选对水稻恶苗病防治效果较好的种子处理剂。[方法]采用9种种子处理剂处理水稻种子,对水稻恶苗病的防治效果进行了试验。[结果]9种种子处理剂中5.5%浸丰2号EC 1∶5 000倍液、12.5%戊氟丹WP 1∶1 000倍液、12.5%戊氟丹WP 1∶1 200倍液、12.5%戊咯丹WP 1∶1 000倍液、12.5%戊咯丹WP 1∶1 200倍液对水稻恶苗病有较好的防治效果,秧田期达90%以上,且有提高水稻发芽率、成苗率、增加田间分蘖的作用。20%氰烯菌脂EC 1∶2 000倍液、20%氰烯菌脂·杀螟丹WP 1∶1 200倍液、16%咪丹WP 1∶400倍液也有较好的防治效果,但明显抑制水稻发芽、成苗和大田分蘖。[结论]5.5%浸丰2号EC 1∶5 000倍液、12.5%戊氟丹WP 1∶1 000倍液、12.5%戊氟丹WP 1∶1 200倍液、12.5%戊咯丹WP 1∶1 000倍液、12.5%戊咯丹WP 1∶1 200倍液可以在生产上推广用于防治水稻恶苗病。

摘  要:
[Objective] In order to screen the best rice seed treatment agent on rice bakanae. [Method]9 kinds of rice seed treatment agent on rice bakanae were tested. [Result]The result showed that 1∶5 000 times liquid of 5. 5% jinfeng 2 EC,1∶1 000 times liquid of 12. 5% wufudan WP,1∶1 200 times liquid of 12. 5% wufudan WP,1∶1 000 times liquid of 12. 5% wuluodan WP,1∶1 200 times liquid of 12. 5% wuluodan WP had better control effect on rice bakanae,and duration in rice nursery above 90%. They can enhance rice germination rate and seedling rate,increase field tillering. 1∶2 000 times liquid of 20% JS399-19 EC,1∶1 200 times liquid of20% JS399-19·cartap EC,1∶400 times liquid of midan WP had better control effect on rice bakanae,but they inhibited germination,seedling formation and field tillering of rice. [Conclusion]1∶5 000 times liquid of 5. 5% jinfeng 2 EC1∶1 000 times liquid of 12. 5% wufudan WP,1∶1 200 times liquid of 12. 5% wufudan WP,1∶1 000 times liquid of 12. 5% wuluodan WP,1∶1 200 times liquid of 12. 5% wuluodan WP can be used in rice practical production.
