DT 杀菌剂是齐齐哈尔市化工研究所1979年研制出的。1983年参加全国大田药效网的试验。从试验结果看,既可防治细菌病,还可防治真菌病,它的杀菌谱较广,是很有前途的新杀菌剂。在黄瓜、茄子等蔬菜上喷用后,经测定,残留在果实里的含铜量仅0.5～1 ppm,低于国家规定标准,对人畜低毒。DT 的药效,经包头农科所和有关单位试验,对黄瓜细菌性角斑病、茄子黄萎病、果树腐烂病、黑星病、李子红点病等都具有明显的 DT fungicide is Qiqihar Institute of Chemical Technology developed in 1979. In 1983 to participate in the field test of the field effect network. From the test results, can prevent bacterial disease, but also prevent fungal disease, its broad spectrum of bactericidal, is a promising new bactericide. After spraying on cucumber, eggplant and other vegetables, it is determined that the content of copper remaining in the fruit is only 0.5-1 ppm, which is lower than the standard stipulated by the state and low toxicity to humans and animals. DT efficacy, the Baotou Institute of Agriculture and the relevant units of the test, the bacterial angular leaf disease cucumber, eggplant Verticillium wilt, fruit rot, Scab, plum red dot disease and so has obvious
