摘要
通过田间药效试验,研究了杜邦福星(40%氟硅唑EC)对甜菜褐斑病的防治效果。田间试验结果表明:杜邦福星3种剂量(30 mL/hm2;60 mL/hm2;90 mL/hm2)对甜菜褐斑病都有明显的防治效果且优于对照药剂禾本卡克(20%三苯基醋酸锡WP)和12.5%烯唑醇WP,3种剂量的防效分别为73.9%、85.3%、87.9%,根产量较空白对照分别增产24%、38%、30.2%,增糖0.46度、0.65度、1.94度。
The control test of 40% flusilazole EC on Cercospora leaf spot of beet in filed was conducted.The results showed that the control effect of three dose 30,60 and 90 ml/ha flusilazole on leaf spot of beet was 73.9%,85.3% and 87.9%,respectively,superior to the controled,20% triphenyl-tin-acetate WP and 12.5% Diniconazole WP.The root yield of sugarbeet was increased by 24%,38% and 30.2%,the sugar content increased by 0.46%,0.65% and 1.94%,respectively.
