广枯灵对烟草猝倒病等病害的防治研究

 1996～1997年研究了广枯灵对烟草猝倒病等病害的防治效果,结果表明:种子消毒、苗床消毒、病苗喷药及病株灌根均可有效防治立枯病、猝倒病、炭疽病和青枯病.5%广枯灵500倍液对立枯病、猝倒病,药后7d防效达100%,对炭疽病药后9d防效达98%,对青枯病防效达93.8%,与对照药剂---甲基托布津、敌克松、波尔多液和抗枯宁比较,药效之间差异极显着.

Study on the Control of Tobacco Seedling Diseases with GKL

The paper reports the control effects of damping off and other tobacco seeding diseases with GKL. The results showed that the GKL is the best disinfectant on seeds and seedling bed, and is also an effective fungicide against damping off, seedling blight, anthrocnose and bacterial wilt of tobacco seedling diseases. The control effect of GKL against damping off and seedling blight up to 100% after 7 days, while that of anthroc nose is 98% after 9 days, bacterial wilt 93. 8%, which make a significant difference than that of Thiophanate- methyl and Femaminosulf.
