世高防治葡萄炭疽病的试验研究

Effect of Score against Grape Bitter Rot in the Field

试验结果表明 :10 %世高WG对葡萄炭疽病有较好的防治效果 ,且对葡萄安全。在葡萄炭疽病大发生年份 ,于葡萄幼果期开始 ,连续用 15 0 0～ 2 0 0 0倍 10 %世高WG施药 4次 ,每次间隔 10d ,即能显著控制病情 ;其对葡萄炭疽病的防效极显著高于 75 %百菌清、5 0 %多菌灵和 70 %代森锰锌 60 0倍。

The test showed that 10% Score WG had good effect on control of Grape bitter rot, and was safety to the grape. 10% Score WG was sprayed four times in 40 days with the germicide diluted for 1?500～2?000 times in its severe epidemic year. The control effect of 10% Score WG was better than that of 75% Chorothalonil、50%Carbendazim and 70%?Mancozeb.
