摘要
用生长速率法测定施保克对水稻秆腐菌核病菌 (Nakataeasigmoideam (Cavara)Hara)菌丝生长有强烈抑制作用 ,毒力回归式为 :Y =84 .81+ 18.6 3X ,EC5 0 =0 .0 135 μL/L ,EC95 =3 5 2 3μL/L方差分析表明 ,预测值与实测值基本吻合。田间药效试验表明 ,在发病初期以 1.12 5L/hm2 用量防效最好 ,达 81.3%。
There was obvious inhibited effect of sportack EC on Nakataea Sigmoideum(Cavara) Hara hyphae growing by methods of growing rate measurment,toxicity regression equation was Y=84.81+18.63X,EC50=0.0135μl.L - 1,EC95=3.5234μl.L - 1.The result of variance analysis showed that was very true .The optimal application dosage is 1.125L/hm 2,chemical control effect can be up to 81.3%.
