田间防治试验表明，印楝素乳油对斜纹夜蛾种群有良好的控制作用，施药7d后其防治效果要优于化学农药10%除尽悬浮剂。

Field experiments confirmed that after 7 days application , azadirachtin could effectively control Spodoptera litura , being more efficient than the chemistry pesticide , 10 % Chu-Jin SC.

对T-N和T-P的去除效果较差。印楝素对低龄幼虫有一定的毒杀活性，而对高龄幼虫活性则很低。

And for T-N and T-P are quite low . Azadirachtin was more efficient for the low instar larva than the old ones .

在（0±1）℃保存14d后这4种溶剂中的印楝素都基本不降解，在室温下保存14d后都只有少量降解。

After storaged at ( 0 ± 1 )℃ for 14 days , azadirachtin in all solutions nearly were not decomposed , and at natural temperature only slight degradation appeared .
