摘 要：
利用10%苯醚甲环唑(世高水分散粒剂)对落叶松落叶病进行了防治试验,室内药效测定结果表明,随药剂质量浓度的提高,对子囊孢子萌发的抑制作用加强,当药剂质量浓度达到0.15 g.L-1时,抑制率达到90.9%;林间药效测定结果表明,随着药剂使用量的增加,防治效果增强,当使用量达到180 g.hm-2时,防治效果达到85.5%;林间防治试验结果表明,当药剂使用量为150 g.hm-2时,防治效果可达到77.7%。

摘 要：
Controlling experiments was conducted to Mycosphaerella larici-leptolepis Ito by 10% difenoconazole,the result of indoor efficacy indicated that inbibitional effect of ascospore strengthened by the increase of concentration.When the concentration of reagent quality reached 0.15 g.L-1,the inhibition ratio was 90.9%;the result of forest efficacy showed that control efficiency enhanced by the increase of application amount.When the application amount achieved 180 g.hm-2,control efficiency was 85.5%;the result of forest control test indicated that control efficiency was 77.7%,when application amount was 150 g.hm-2.
