贺兰山东麓葡萄毛毡病消长动态以及新型防控药剂的研究

Evaluation of Insecticides to Control Grapevine Erinose and the Population Dynamics in Helan Moutain Eastern

以赤霞珠为试验品种,40%与50%仿生胶和10%浏阳霉素乳油为试验药剂,40%毒死蜱乳油、1.8%阿维菌素乳油和20%哒螨灵可湿性粉剂为对照药剂,研究毛毡病的消长动态和防治毛毡病的新型农药,探讨贺兰山东麓葡萄毛毡病消长动态以及2种防治药剂在不同时期对其的影响。结果表明:引起葡萄毛毡病的葡萄缺节瘿螨1a发生3代。在整个葡萄生育期中的危害有2次低谷时期:5月中旬和7月中旬。40%与50%仿生胶对葡萄毛毡病有很好的防控效果,药后21 d防效可以达到87.00%以上,而且对葡萄生长没有影响,是防治葡萄毛毡病的新型农药。在葡萄膨大期,10%浏阳霉素乳油可以有效控制葡萄毛毡病的发生。毛毡病的防治时期以葡萄刚出土时预防为最佳时期。葡萄毛毡病在贺兰山东麓发生普遍且危害重,在葡萄刚未展叶以前施用仿生胶可以有效地控制毛毡病的发生及危害。

Investigation about population dynamics and evaluation of insecticides to control grapevine erinose had been taken in Helan Moutain Eastern.The test cultivar was Cabernet Auvignon,the test chemicals were 40%biomimetic adhesive and 50%biomimetic adhesive.The CK of insecticides were 10%liuyangmycin EC,40%pierisrapae granulosis virus(PrGV ) EC,1.8%Abamectin EC and 20%Ridaben WP.The result showed that grapevine erinose had 3 generations.Whatsmore there were 2 low vally periods.They were middle of May and middle of Jume respectively.40% biomimetic adhesive and 50%biomimetic adhesive could effectively control grapevine erinose at the grape sprouted out of the earth stage.The control effect of after 21 d was beyond 87%.Moreover,biomimetic adhesive didn't damage to grapes and animals.It was new and effective chemical.10%liuyangmycin EC could control grapevine erinose effectively too at the grape enlarge period.The optimal period was he grape sprouted out of the earth stage.Grapevine erinose was general and harmful in Helan Moutain Eastern.Biomimetic adhesive could be used to control erinose effectively at the grape sprouted out of the earth stage.
