防治苗木猝倒病,是育苗者的一项重要工作。一往人们采用多菌灵等药物防治苗木猝倒病,但效果不够理想。而采用新洁尔灭防治苗木猝倒病,每亩用量仅40克(合人民币0.13元左右),比用多菌灵每亩可节约成本费0.47元。同时可降低苗木发病率13.2～16.4％。每亩减少发病株数约4～5千株。新洁尔灭的使用方法很简单。将5％的医用新洁尔灭配制成1:2000倍液后,喷洒苗木即可达到 Prevention of seedling damping-off disease is an important work nursery. People use carbendazim and other drugs to prevent seedling damping-off disease, but the effect is not ideal. The use of benzalkonium bromide seedling damping-off disease prevention, the amount of only 40 grams per mu (about 0.13 yuan), than carbendazim per acre can save cost of 0.47 yuan. At the same time can reduce the incidence of seedlings 13.2 ~ 16.4%. Decrease the number of plants per acre about 4 to 5 thousand strains. Bromozide is easy to use. 5% of the medical benzalkonium bromide formulated into 1: 2000 times the solution, spray seedlings can be achieved
