创制除草剂单嘧磺隆应用研究

Applied Research of a New Sulfonylurea Herbicide Monosulfuron

单嘧磺隆是一种高效、低毒除草剂。详细介绍了单嘧磺隆的理化性质、毒理学、环境行为和残留研究。并对单嘧磺隆及其相关产品在小麦、谷子、玉米、水稻等作物田的广泛应用进行了系统的总结。结果表明:单嘧磺隆为低毒农药且对环境安全,无致畸、无致突变、无致癌作用。在推荐剂量下,能有效防除一年生阔叶杂草,而且对作物安全,适宜加工成多种混剂和剂型。

Monosulfuron is a sulfonylurea herbicide with ultra-low dosage. The physical and chemical properties, toxicology, environmental toxicology and residual of monosulfuron, and extensive application of related products in wheat, millet, corn, rice and other crop fields were summarized. Results indicated that monosulfuron was low toxicity and environmental-benign properties. Its ames assay, micronucleus or bone marrow cells chromosomal aberrations and dominant lethal or germinal cell chromosomal aberrations were negative. Appropriate use rates of the monosulfuron can effectively control annual broadleaf weeds and it was safe to corns. Moreover, It can be applied with different mixture and formulations.
