Rice Sheath blight control period control technique
针对耕作制度、种植结构调整，使水稻纹枯病发生早，为害加重的新情况，研究改进了水稻纹枯病的防治技术。在充分发挥农业措施控害的基础上，进一步优化药剂防治策略。第一次药剂防治期提早至始病期(病丛率3％-5％)，第二次药剂防治加大用药量，每667m2用20％井冈霉素SP 50 g，较传统的方法提高了纹枯病防治的整体效果。
針對耕作製度、種植結構調整，使水稻紋枯病髮生早，為害加重的新情況，研究改進瞭水稻紋枯病的防治技術。在充分髮揮農業措施控害的基礎上，進一步優化藥劑防治策略。第一次藥劑防治期提早至始病期(病叢率3％-5％)，第二次藥劑防治加大用藥量，每667m2用20％井岡黴素SP 50 g，較傳統的方法提高瞭紋枯病防治的整體效果。

Because of the adjustment of cropping pattern, rice sheath blight has been occurring more serious.The control technique of rice sheath blight was improved by this research, Based on fully resorting to agricultural measures, the control strategies was made better. The first chemical control time can be earlier at the beginning of disease, with the incident of 3% to 5%. The second chemical control use 50 g 20% Jinggangmycin SP in each 667 m2. Compared with the tradition methods, the rice sheath blight was controlled more effectively by the new method.
