拉索化学成分属氯代乙酰胺类,纯品为非挥发性结晶固体,在水中溶解为240ppm,其商品多制成乳剂。拉索属于苗前施用的选择性除草剂,具有高效、低毒、低残留,对作物安全,除草广谱、施用方便、经济等优点,近年,国内许多地区已开始用于旱田除草。为进一步了解拉索在砂壤中的残留期和除草效果,我们在院内试验地进行了敏感性和残留动态的试验,其结果如下:一、田间试验设置试验在院内试验地进行。土壤为河淤土,
Cable chemical composition is a chloroacetamide, pure non-volatile crystalline solid, dissolved in water as 240ppm, the more the goods made from emulsion. It has the advantages of high efficiency, low toxicity and low residue, safe for crops, broad spectrum of weeding, convenient application and economy. In recent years, many regions in China have begun to weed herbicides. In order to further understand the retention time and herbicidal effect of cable in sand soil, we carried out the experiment of sensitivity and residual dynamic in the field experiment. The results are as follows: 1. The field experiment setup test was carried out in the hospital experimentally. Soil for the river silt soil,
