Abstract
- [Objective] The paper was to confirm the best application period and frequency of 7 5% trifloxystrobin • tebuconazole WG against rice blast and rice sheath blight. [Method] Influences of different dosages and different application periods of 7 5% trifloxystrobin • tebuconazole WG on control effects against rice blast and rice sheath blight, as well as their effects on rice yields were studied in the paper. [Result] The control effects of three different fungicides application treatments against rice sheath blight were 80.24%, 83.0% and 67.99%, and the control effects against rice blast were 56.4%, 49.11% and 61.1%, respectively. Advanced application of fungicide for two times had good prevention effect against rice sheath blight; properly delayed application of fungicides for two times was conducive to improving the control effect against rice blast, and one time application of sufficient fungicide during middle booting stage had higher control effect than application for two times. Effective panicle number per unit area, total grain number, 1000-grain weight and moisture content of various fungicide application treatments did not have significant difference with those of the treatments without fungicide application, but grain number per panicle in treatments applied with fungicide was higher than the treatment without application. [Conclusion] 75% Trifloxystrobin • tebuconazole WG has better control effect on rice blast and sheath blight, which helps to promote the formation of rice grain and increases yield significantly. The fungicide application against rice sheath blight should be appropriately advanced , and application for one time against panicle blast after middle booting stage is helpful to improve the control effect.
