摘要
为了验证9%吡唑醚菌酯悬浮剂对水稻稻瘟病的防治效果、对水稻的安全性,以及对作物产量的影响,特做此试验。试验结果表明:9%吡唑醚菌酯悬浮剂对水稻穗颈瘟有较好的防治效果,于水稻破口期、齐穗期各施药1次,防效为98.53%,高于对照药剂的防效;水稻产量为622.37 kg/667 m^2,较空白对照增产71.99%;在试验剂量范围内对水稻安全。推荐用药量为60 ml/667 m^2兑水30 L均匀喷雾。
The test of 9%pyrazole ester suspension agent(Daoqing)on rice blast were made to research the effect on control efficiency,security and yield.The result indicated that 9%pyrazole ester suspension agent(Daoqing)had better control effect on neck blast,the control effect could reach to 98.53%by applying pesticide once at the rupturing stage and full heading stage,the effect was higher than the control.The yield was 622.37 kg/667 m^2 and increased by 71.99%than the control,it is safe for rice in the range of experimental dose.The recommended dosage was 60 ml/667 m^2(Water-adding 30 L)and evenly spray.
