棉花枯、黄萎病在棉花生产上为害日益严重,成为影响棉花高产稳产的突出问题。棉花枯萎、黄萎病菌是以种子带菌作远距离传播的病害,被列为国内及对外植物检疫对象。江苏省农科院从七十年代初期开始,先后对棉种接种枯萎、黄萎病的技术进行了研究,取得了种子内部带菌率高的成功方法,为棉种消毒研究提供了可靠保证。使用有效浓度0.3%的多菌灵胶悬剂(具体配方是100斤水中加40%的多菌灵胶悬剂0.75斤),在常温下浸种14小时,浓度不宜增加,时间亦无需延长。药液浸种后的棉籽不宜在温箱平皿内的发芽率的测定,可进行
Cotton withered, Verticillium wilt damage in the cotton production is becoming increasingly serious, become a prominent problem affecting the high and stable yield of cotton. Cotton withered, Verticillium dahliae is a disease carried by long-distance transmission by seed carriers and is classified as a quarantine object for domestic and foreign plants. Since the early 1970s, Jiangsu Provincial Academy of Agricultural Sciences has studied the technology of seeding wilt and Verticillium wilt. The successful method of high inoculation rate in the seeds has been obtained, which provides a reliable guarantee for the disinfection of cotton varieties. The effective concentration of 0.3% carbendazim suspension (specific formula is 100 kg of water plus 40% of the carbendazim suspension 0.75 kg) soaking at room temperature for 14 hours, the concentration should not increase the time without the need to extend. After soaking cottonseed solution should not be measured in the incubator sprouting rate can be carried out
