砜嘧磺隆在土壤中的动态消解规律

Dynamic Digestion Patterns of Rimsulfuron in Soil

摘要

“薯/玉/豆”带状复合种植技术中，由于作物栽培时间和生育期不一致导致田间杂草管理难度较大，符合该技术的除草剂鲜有报道。砜嘧磺隆杀草谱广、选择性好，可较好应用到该技术中。为准确评价砜嘧磺隆在土壤中的残留动态，明确其在“薯/玉/豆”带状复合种植技术中应用的安全性，采用室内模拟试验，应用高效液相色谱法测定砜嘧磺隆在土壤中的残留。25%砜嘧磺隆水分散粒剂在施药量为0.5~2.0 mg/kg时，在土壤中半衰期为7.70~9.50 d，9.50 d内降解量为初始沉降剂量一半，在施药42 d后土壤残留量为0.001 8~0.009 0 mg/kg。为确保安全使用砜嘧磺隆，最大限度减轻除草剂造成的药害，施用砜嘧磺隆9.50 d后再栽培其他作物相对安全。

Abstract

Weed management in the "potato/maize/bean" strip combined planting technology is difficult because of the inconsistency of cultivation time and fertility period of the corps. In particular, there are very few herbicides that conform to this technology. Rimsulfuron, as a herbicide with wide spectrum and good selectivity, has been effectively applied to the planting pattern. In order to accurately evaluate the residual dynamics and safety of rimsulfuron in the "potato/maize/bean" cultivated soil, the residues of rimsulfuron in soil were determined by high performance liquid chromatography (HPLC) simulated in the laboratory. When the dosage was 0.5-2.0 mg/kg, the half-life of rimsulfuron 25% WDG in soil was 7.70-9.50 days. The degradation of herbicide on 9.50 days was reduced to half of the initial settlement dose, and the pesticide residue in soil was only 0.001 8-0.009 0 mg/kg after 42 days of application. To ensure the safe use of rimsufuron and minimize the possible damage, it is recommended to apply rimsulfuron at least 9.50 days before planting other crops.
