摘要
为有效控制纵坑切梢小蠹的危害,了解梢转梢、梢转干期化学药剂防治该虫效果,在白沙地做了化学药剂防治纵坑切梢小蠹药效试验。在施药剂量为15kg/hm^2条件下,纵坑切梢小蠹死亡率为:梢转梢期,灵秀1号14.81%、川宝47.13%、吡虫啉20%、护林神25.30%、对照9.23%;梢转干期,灵秀1号43.59%、川宝73.33%、吡虫啉47.25%、护林神56.82%、对照9.72%。
Chemical control experiment against Tomicus piniperda was made and the result showed when Lingxiu I ,Chuanbao ,imidacloprid and Hulinshen were applied at the dosage of 15kg/hm^2 in the period of the move among shoots, the mortality rates of Tomicus piniperda were 14. 81% ,47. 13%, 20% and 25.30% respectively while that of the control was 9.23%. When the above pesticides were applied at the same dosage in the period of the move from shoots to trunks, the mortality rates of Tomicus piniperda were 43.59 % ,73.33% ,47.25% and 56. 82% respectively while that of the control was 9.72%.
