A 36% emulsion oil of Illoxan is currently an ideal herbacide for sugar beet, both domestically andabroad. The purpose of studying the degradation and residue dynamics under field condition was to providenecessary residue data of this herbacide for its reglstered from and at the same time to make a scientificbasis for its "standard of safe usage" . From 1984 to 1985, the authors used three dosages for Illoxan onexperimental fields on Zhejiang province, Beijing municipality and Helongjiang province at: 83 ml/mu, 125ml/mu and 16T ml/mu. After 92-106 days of application, no residue of Illoxan could be detected in thebeet tubers, nor in the soil.It was suggested that the interval for safe application of Illoxan should be 106days, the permissible residual amount eas 0.1 mg/kg and the application rate should be one per growingseason at the rate of 83 ml/mu.

伊洛克桑36%乳油是目前国内外防除甜菜田杂草的理想除草剂。研究伊洛克桑在甜菜上及其在土壤环境中的消解和残留动态,目的在于提供伊洛克桑在登记资科中不可缺少的残留数据,同时为制订伊洛克桑在甜菜上的“安全使用标准”提供依据。1984年至1985年在浙江、北京、黑龙江等试验基地采用伊洛克桑83ml/亩、125ml/亩和167ml/亩的三个剂量施药除草,在施药后92—106d,甜菜块茎和土壤中伊洛克桑的残留量均未检出。建议伊洛克桑在甜菜上的安全间隔期为106d,允许残留量为0.1mg/kg,使用药量为83ml/亩,施药方法为喷雾,施药次数为1次。

The degradation and metabolism of a new insecticide Chlorobenzuron or 1-(4-chlorophenyl)-3-(2-chlorobenzoyl) urea (CCU) under aerobic aquatic environment are reported in this paper. Through observations on the process of the breakdown of CCU and the production of two primary metabolites under dark condition in sterilized group and test one respectively, the differences between chemical hydrolysis and biodegradation were compared, in a laboratory model aerobic system, the residue dynamics and biodegradation half life for the parent compound, and the major conversion products of its primary metabolism pathway were investigated. Meanwhile, two main metabolites were measured and identified by high performance liquid chromatography, UV absorbance spectrum scanning and characteristic mass spectra. All the results obtained show that chlorobenzuron is less stable, its hydrolysis is affected by microorganisms. The main pathway of the primary metabolism for the parent compound in water is the cleavage of the bond between benzoyl carbon and urea nitrogen, producing orthochlorobenzoic acid (CBA) and 4-chlorophenylurea (CPU).

本文研究了新农药灭幼脲Ⅲ号在好气水环境中的降解与代谢。在避光条件下,观察了灭菌组与实验组中灭幼脲Ⅲ号及其主要代谢产物的消长过程,比较了它的化学水解与微生物降解的差异。在室内模拟好气系统中,研究了母体化合物在水体中的残留动态和生物降解半衰期,及其初期主要代谢途径的转化产物,同时分别用高效液相色谱法,紫外吸收光谱扫描,以及特征有机质谱图,对灭幼脲Ⅲ号的两种主要代谢产物进行了定性定量测定。结果表明:灭幼脲Ⅲ号在室内好气环境中较易水解,而且水中微生物的存在能加速它的降解,母体化合物在水体中初期代谢主要途径为分子中的苯甲酰碳与脲氮键首先开裂,生成邻氯苯甲酸(CBA)和对氯苯基脲素(CPU)。

The present paper deals with the residue dynamics of carbendazim in spruce seedling and soil using 14C-carbendazim to control thesnow blights and molds of spruce under simulated early winter and snow covered conditions.The rate of 14C-carbendazim used was 2g/m2.The results showed that almost all the 14C-carbendazim was absorbed on the surface of the needles and that the degradation was so slowly that 22.78μg/g residue was still on the needle surface after 150 days(just as late snow-melting period).89%14C-carbendazim...

采用同位素14C示踪技术,研究初冬喷施多菌灵等防治云杉雪霉病和雪枯病,在雪盖条件下,药剂在云杉幼苗和土壤中的残留动态。结果表明,绝大部分药剂吸附在针叶表面,降解十分缓慢,150天时(相当融雪后期)残留量为喷药当天原始沉积量的48.4%,高出病原菌的平均抑制中量5.2μg/g;多菌灵在土壤中的移动性很小,全部剂量都集聚在0—10cm表土层中,在0—2cm土层中,占总量的72.5%,从而对田间试验筛选出的多菌灵,以及与其性能相近的甲基托布津、粉锈宁等杀菌剂的防治效果做出了准确的评价。
