田间试验结果表明,“丙环·嘧菌酯+天然螯合硼钙”组合对水稻后期综合性病害有较好的控制作用及增产效果。在水稻分蘖末期、孕穗中期每667 m²连续使用19%丙环·嘧菌酯SE 50 mL+天然螯合硼钙50 mL后,对稻瘟病、稻曲病的防治效果分别高达95.1%和97.8%,极显著优于施用75%肟菌·戊唑醇WG 10 g和32.5%苯甲·嘧菌酯SC 30 mL的处理,且安全性好、增产效果明显。“丙环·嘧菌酯+天然螯合硼钙”组合在当前水稻生产上有较好的推广应用前景。

Field test results showed that the combination of “propiconazole azoxystrobin + natural chelated boron calcium” has a better control effect on the comprehensive diseases in the late stage of rice and yield increase. After the continuous use of 19% propiconazole azoxystrobin SE 50 mL/667 m² + natural chelated boron calcium 50 mL/667 m² at the end of tillering and mid booting stage of rice, the control effects on rice blast and rice smut were as high as 95.1% and 97.8%. It was significantly better than the treatment of 75% oximeximab · tebuconazole WG 10 g/667 m² and 32.5% benzoxystrobin SC 30 mL/667 m², And the safety is good. The effect of health care and production increase is very obvious. It has a good application prospect in rice production.
