摘要
以康地蕾得、青萎散、青枯灵、硫酸链霉素为对象,探讨不同药剂对烟草青枯病的防治效果,旨在为湖南烟区青枯病的防治提供参考依据。结果表明,康地蕾得、青萎散、青枯灵的防治效果均较好,其中以康地蕾得(3 000 g/667m2)效果最佳。建议在青枯病发生较轻的烟区,采用康地蕾得、青萎散、青枯灵进行防治,用药量分别以每667 m2用2 000 g、2 500 g、400 g为宜,而对于较重发生的烟区,最好使用康地蕾得3 000 g/667m2,分别于移栽期、揭膜期、团棵期、旺长期各施药1次。
In order to find the methods of controlling tobacco bacterial wilt in Hunan, the control effects of four pesticides such as Paenibacillus polymyza, Pseudomonas fluorescens, QingKuling and Streptomycin on tobacco bacterial wih were studied. The results showed that paenibacillus polymyza, pseudomonas fluorescens and QingKuling were all effective. The most effective pesticides was Paenibacillus polymyza （3 000 g/667 m^2）. The author suggested control tobacco bacterial wilt with Paenibacillus polymyza （2 000 g/667 m^2）, Pseudomonas fluorescens （2 500 g/667 m^2） and QingKuling （400 g/667 m^2） in mild occurrence regions with bacterial wih, but in damaged regions, 3 000 g Paenibacillus polymyza per 667m^2 should be applied respectively in transplanting period, uncovering date, spherical plant stage, vigorous growth period.
