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%。
利用10%苯醚甲環唑(世高水分散粒劑)對落葉鬆落葉病進行瞭防治試驗,室內藥效測定結果錶明,隨藥劑質量濃度的提高,對子囊孢子萌髮的抑製作用加彊,噹藥劑質量濃度達到0.15 g· L-1時,抑製率達到90.9%;林間藥效測定結果錶明,隨著藥劑使用量的增加,防治效果增彊,噹使用量達到180 g · hm-2時,防治效果達到85.5%;林間防治試驗結果錶明,噹藥劑使用量為150 g· hm-2時,防治效果可達到77.7%。
이용10%분미갑배서(세고수분산립제)대락협송락협병진행료방치시험,실내약효측정결과표명,수약제질량농도적제고,대자낭포자맹발적억제작용가강,당약제질량농도체도0.15 g· L-1시,억제솔체도90.9%;림간약효측정결과표명,수착약제사용량적증가,방치효과증강,당사용량체도180 g · hm-2시,방치효과체도85.5%;림간방치시험결과표명,당약제사용량위150 g· hm-2시,방치효과가체도77.7%。
Controlling experiments was conducted to Mycosphaerella larici-leptolepis Ito by 10% difenocon-azole, 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 .
