对300 g/L苯醚甲环唑.丙环唑EC防治水稻纹枯病进行田间药效试验,结果表明,300 g/L苯醚甲环唑.丙环唑EC有效成分90 g/hm2、112.5 g/hm2对水稻纹枯病的防治效果分别为85.48%、93.54%,比10%苯醚甲环唑EC 22.5 g/hm2处理分别提高8.15、16.21个百分点;比25%丙环唑EC 112.5 g/hm2处理分别提高15.66,23.72个百分点;比300 g/L苯醚甲环唑.丙环唑EC67.5 g/hm2处理分别提高19.29、27.35个百分点。300 g/L苯醚甲环唑.丙环唑EC防治水稻纹枯病的有效成分为90.0～112.5 g/hm2。
The field efficacy test of 300 g / L difenoconazole and propiconazole EC against rice sheath blight showed that 300 g / L difenoconazole and propiconazole EC were the effective components of 90 g / hm 2, The control effects of 112.5 g / hm2 on rice sheath blight were 85.48% and 93.54%, respectively, which were 8.15 and 16.21 percentage points higher than those of 10% difenoconazole EC treatment at 22.5 g / hm2, respectively. Compared with 25% propiconazole EC 112.5 g / hm2 treatment increased by 15.66 and 23.72 percentage points respectively, which was 19.29 and 27.35 percentage points higher than that of 300 g / L difenoconazole and propiconazole EC67.5 g / hm2, respectively. 300 g / L difenoconazole.Effects of propiconazole EC against rice sheath blight were 90.0 ~ 112.5 g / hm2.
