811927是防治水稻白叶枯病的新型内吸性杀菌剂。化学名称为氨基硫脲乙醛酸腙,结构式H_2N S=C NHN=CHCOOH,熔点为165℃,在水中有相当的溶解度。早有报道,811927易被植物根部吸收并传导至幼苗上,温室和田间小区试验证明它没有药害,而且对自叶枯病的防效比叶枯净好,特别是它在细胞毒性体内试验中没有显示出对细胞的毒性效应。在1980～1983年连续四年的温室植株试验中,我们对811927防治水稻白叶枯病以及杀菌特性和稳定性进行了初步研究,结果表
811927 is a new systemic fungicide against bacterial leaf blight. Chemical name is thiosemicarbazone glyoxylic acid hydrazone, the structural formula H_2N S = C NHN = CHCOOH, the melting point of 165 ° C, have considerable solubility in water. It has long been reported that 811927 is easily absorbed by plant roots and transmitted to the seedlings. Greenhouse and field plot tests show that it has no phytotoxicity and is more potent against leaf blight than leaf blight. In particular, it is tested in cytotoxicity Did not show toxic effects on the cells. In the greenhouse experiment of four consecutive years from 1980 to 1983, we conducted a preliminary study on the control of bacterial blight and the bactericidal properties and the stability of 811927.
