DTM(羧酸铜磷铝可湿性粉剂)是一种具有内吸双向传导作用的高效杀菌剂。室内平板抑菌试验表明,它对棉花黄萎病菌的EC50为509.56倍,EC95为315.55倍。DTM对种子发芽安全浓度为100~400倍,且以300倍药液效果最佳。1991~1994年多点田间药效试验表明,以300倍药液浸种并在棉花黄萎病的发病始期和两个高峰期喷药防效最佳,其病情指数降低率为41.84%。
DTM (Copper Copper Phosphorus Aluminum Carbide Wettable Powder) is an efficient biocide with internal bi-directional conduction. The indoor antibacterial test showed that it showed an EC50 of 509.56 folds and an EC95 of 315.55 folds to Verticillium dahliae. DTM seed germination of the safe concentration of 100 to 400 times, and 300 times the best solution. The results of multi-point field trials from 1991 to 1994 showed that the soaking rate of 300 times and the best anti-infective efficacy were 41.84% at the initial and two peak stages of cotton Verticillium wilt.
