【摘要】 目前烟草的种子处理普遍采用１％硫酸铜浸种消毒法，试验证实它并不能很好地杀灭种子上所携带的赤星病菌和野火病菌。药物消毒中用扑海因、菌核净浸种效果差；链霉素浸种对野火病菌效果很好．但对赤星病菌则差；用０．１％硝酸银浸３０ｍｉｎ或用温汤浸种中的５０℃浸１０ｍｉｎ则对赤星病菌和野火病菌防治效果均很好。这两种消毒法对种子发芽安全，可在生产上应用。更多还原

【Abstract】 At present. 1%SuSO4 as a disfectant is gernerally remmended. but it is niether effective for brown spot. nor for wildfire. Rovral and Dimelhachlon were shown to be ineffective against brown spot and wildfire, Streptomycin was effective to to wildfire but not to brown spot. 0. 1% silver nitrate 30 minutes or 50℃ hot water 10 minutes were effective both to brown spot and wildfire. And it is not deleterious effective upon seed germination. So it can be recommend as seed treatment methods in tobacco growing areas.更多还原
