摘要:
用生长速率法测定施保克对水稻秆腐菌核病菌(Nakataea sigmoideam (Cavara)Hara)菌丝生长有强烈抑制作用, 毒力回归式为:Y =84 .81 +18 .63X , EC50 =0 .0135 μL/L,EC95 =3.523 μL/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 .125 L/hm2 用量防效最好, 达81 .3 %。
Abstract:
There was obvious inhibited effect of sportack EC on Nakataea Sigmoideum (Cavara)Hara hyphaegrowing 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 optimalapplication dosage is 1 .125L/hm2 , chemical control effect can be up to 81 .3 %.
