摘要
通过采用13%多·硫烟剂对云杉落针病进行防治试验,结果表明:13%多·硫烟剂防治云杉落针病的适宜用药量为15 kg/hm2,5月下旬至6月中下旬为防治最佳时机,防治2次最为理想,防治效果可达65%以上,并对人畜无害和云杉生态安全,可在林区大面积推广应用。
Control experiment on needle cast ofLophodermium piceae was conducted through applying more than 13% Carbendazim＋Sulfur fumigant, the results indicated： the suitable dose of more than 13% Carbendaz-im＋Sulfur was 15 kg/hm2, from last May to the middle and last June was the best time for controlling and two times was ideal, controlling effect may reach above 65%, and it was harmless to human-livestock and ecological security of Lophodermium piceae, which should be promoted and applied in big-area of the forest region.
