| 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 effica- cy research from 2012 to 2013. The results showed that 25% Tebuconazole WG were effective to against rice blast,control effect was 67.8-85.9M ,and it had good effect on rice yield,the increasing rate was 17.5%-34.4%. In production, it was suggested that rice blast should be controlled with 25M Tebuconazole WG for 258 g·hm^-2 which was added water for 600 kg·hm^-2 ,spraying on rice plants first on booting stage, and second for 15 days after the first applying. |
