试验研究证明,棉花枯萎病病株的棉籽能携带枯萎病菌,随着种籽调运,传播蔓延。长期以来,在处理棉种,消灭内部枯萎病菌方面,国内外都做了一些工作,但到目前为止,均未达到预期效果。我们从1970年冬季开始进行棉种药剂浸种试验。在平板培养基上筛选杀菌剂和抗生素约500种,选出有效药种近90种,其中以苯骈咪唑效果最好。 试验方法;采用经过枯萎病菌孢子液接种的棉籽(内部带菌率一般20.48—95％,平均65.48％),通过一系列处理试验,先后分 Experimental studies have shown that the cotton seedlings of cotton wilt disease can carry Fusarium wilt, spread with the spread of seeds spread. For a long time, some work has been done both at home and abroad in dealing with cotton species and eliminating internal Fusarium wilt, but so far they have not achieved the desired results. We started soaking cotton seeds in the winter of 1970. About 500 kinds of bactericides and antibiotics were screened on the plate medium, and nearly 90 kinds of effective drugs were selected, of which benzodiazepine was the best. Test method; Fusarium oxysporum spores after inoculation of cottonseed (internal carrier rate of 20.48-95%, average of 65.48%), through a series of handling tests, successively
