19%丙环·嘧菌酯SE与生物刺激素混合防治水稻后期综合性病害及增产效果

Control and Yield Increase Effects of Mixed Application of 19%Propiconazole azoxystrobin SE with Biostimulant on Comprehensive Diseases at Late Stage in Rice

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 m^(2)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 m^(2)+natural chelated boron calcium 50 mL/667 m^(2) 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 m^(2) and 32.5%benzoxystrobin SC 30 mL/667 m^(2),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.
