- Abstract
[Objective] The efficacy of difenoconazole-azoxystrobin 32.5% SC for rice sheath blight and its application technology were discussed in this research. [Method] Three surveys were carried out. There were 5 fixed test clumps in each plot. The number of total plants and disease plants and disease progression in each fixed clump were recorded. The correlation effectiveness was calculated based on the growth rate of disease index. Significance analysis was performed with Duncan's new multiple range method (DMRT). [Result] The difenoconazole-azoxystrobin 32.5% SC had a good efficacy for rice sheath blight, and its efficacy increased with the increase of dose. If sprayed according to the dose of 450 ml/hm2 5 days before the beginning of heading stage of rice, difenoconazole-azoxystrobin 32.5% SC would have better effects on controlling rice sheath blight with correlation effectiveness reaching up to 95.14%, which was 2.06% higher than that of control drug (trifloxystrobin-tebuconazole 75% WG, 225 g/hm2). [Conclusion] Treated with difenoconazoleazoxystrobin 32.5% SC with dose of 450 ml/hm2, rice would have green upper leaves and less yellow middle and lower leaves. Moreover, the yield was increased significantly. The difenoconazole-azoxystrobin 32.5% SC had good safety. Therefore, difenoconazole-azoxystrobin 32.5% SC had a good application prospect in production.
