DT杀菌剂是齐齐哈尔市化工研究所1979年创制出的新杀菌剂,1983年已参加全国大田药效网的试验,从目前试验结果看,它的杀菌谱较广,是一个很有前途的新杀菌剂。 化学名称为丁二酸铜,纯品外观为淡兰色粉末,在pH中性范围内稳定,现在生产的剂型是30％胶悬剂,对人畜低毒,小白鼠口服急性致死中量LD_(50)为2646毫克/公斤体重。在黄瓜、茄子等蔬菜作物上喷用后,经测定,残留在蔬菜果实里的含铜量仅为0.5—1ppm,低于国家规定标准(国家颁布食用水含铜标准不得超过3ppm)。 药效:经我所和有关单位试验表明,DT杀菌剂对黄瓜细菌性角斑病、茄子黄萎
DT germicide is Qiqihar Institute of Chemical Industry in 1979 created a new fungicide, 1983 has participated in the field test of the field network, from the current test results, it is a broad spectrum of bactericidal, is a promising new Bactericide. The chemical name is copper succinate, pure appearance is light blue color powder, stable in the pH neutral range, the dosage form produced now is 30% suspension, low toxicity to humans and animals, acute oral death in mice LD_ ( 50) was 2646 mg / kg body weight. After spraying on cucumber, eggplant and other vegetable crops, it is determined that the copper content remaining in the fruits and vegetables is only 0.5-1ppm, which is lower than the standard stipulated by the state (the national standard for copper content in edible water should not exceed 3ppm). Efficacy: The test by our institute and the relevant units showed that DT fungicide had effects on bacterial angular leaf spot of cucumber,
