| 摘 要： | 在林间应用25%嘧菌酯悬浮剂对落叶松落叶病和枯梢病进行共同药效测定和防治试验,结果表明:在药效测定中,200 g(a.i.)·hm-2剂量防治落叶病效果为86.0%;250g(a.i.)·hm-2和300 g(a.i.)·hm-2剂量防治枯梢病效果分别为85.4%和87.1%。在防治试验中,250 g(a.i.)·hm-2和300 g(a.i.)·hm-2剂量防治落叶病效果分别达到87.1%和88.7%;使用相同剂量药剂防治枯梢病效果分别为86.7%和88.9%。建议林间应用防治剂量为200~300 g(a.i.)·hm-2。两种病害在同一林分共同防治时,应重点考虑对枯梢病防治效果。

| Abstract: | The evaluation of pesticide effectiveness and controlling experiments to Mycosphaerella laricis-leptolepiis and Botryosphaeria laricina were carried by applying 25%azoxystrobin suspending agent in woodland.The result showed that Mycosphaerella laricis-leptolepiis control effect of 200 g(a.i.)· hm-2 was 86.0%and the Botryosphaeria laricina control effect of 250g(a.i.)· hm-2 and 300 g(a.i.)· hm-2 was 85.4% and 87.1% in evaluation of pesticide effectiveness. And Mycosphaerella laricis-leptolepiis control effect of 250 g(a.i.)· hm-2 and 300 g(a.i.)· hm-2 was 87.1% and 88.7%and Botryosphaeria laricina control effect with the same dosage was 86.7%and 88.9%.The suggestion was control dosage in forest was between 200 g(a.i.)· hm-2 and 300 g(a.i.)· hm-2.The Botryosphaeria laricina control effect should be mainly considered when they were controlled in the same time and forest stand. |
