@@@@The reduction of pest control 30% difenoconazole ? propiconazole EC and routine control of 20%validam ycin SP against sheath blight were compared, the control efficacy of 30% difenoconazole ? propiconazole against sheath blight were evaluated. The results show that, 30% difenoconazole ? propiconazole EC has good control efficacy on Rhizoctonia solani, the average control efficacy reached up to 84.14%, and it was 4.62% higher than the control efficacy of 20% validam ycin SP? reduction of pest control region 667 m2 yield 527.9 kg while conventional medication 20% validam ycin SP control area 667 m2 yield 496.7 kg, the former increase 31.2 kg/u, which increase by 6.28%. The pesticide employment is less 2.5 yuan/u, increase benefit 62.9 yuan/u. The results suggest that 30% difenoconazole ? propiconazole EC 30 mL/u with added water 45 kg/u against rice sheath blight by foliar spray evenly at the occurrence stage of sheath blight.
