- 摘要:
- 为探讨新型杀菌剂对水稻稻瘟病的防治效果,以水稻品种松粳9号为试材,研究25%戊唑醇WG对水稻稻瘟病的防效。2012~2013年田间试验结果表明:25%戊唑醇WG对水稻稻瘟病叶瘟的防治效果为78.5%~90.1%,对穗颈瘟的防治效果为67.8%~85.9%,并有一定的增产效果。25%戊唑醇WG的适宜用量为258 g.hm2,兑水600 kg.hm2,均匀喷施于水稻植株上,于水稻孕穗期第1次施药,15 d后第2次施药。
- Abstract:
- In order to investigate the control effect of new sterilization agent on rice blast,taking Songjing 9 as test material,the control effect of 25% Tebuconazole WG against rice blast was studied through the field efficacy research from 2012 to 2013.The results showed that 25% Tebuconazole WG were effective to against rice blast,control effect was 67.8%~85.9%,and it had good effect on rice yield,the increasing rate was 17.5%~34.4%.In production,it was suggested thatrice blast should be controlled with 25% Tebuconazole WG for 258 g?hm2 which was added water for 600 kg?hm2,spraying on rice plants first on booting stage,and second for 15 days after the first applying.
