拉索Lasso是美国孟山都公司1970年发展的优良旱田除草剂,又称Alachlor,被译为“草不绿”。它是一种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、残效较长、使用经济等优点。在美国拉索原药年产已超过万吨,已成为大豆地最广泛应用的除草剂品种之一。近两年来,我国东北国营农场用它在大面积上防除大豆杂草,曾获得较好的除草效果。

Lasso is the fine dry herbicide developed by Monsanto in 1970 in the United States. It is also called Alachlor and is translated as “grass is not green.” It is a kind of selective herbicide applied pre-emergent, with high efficiency, low toxicity and low residue, safe for crop, broad spectrum of weeding, convenient application, long residual effect and economy. In the United States the original annual production capacity of more than 10,000 tons of raw drugs, soybean has become one of the most widely used varieties of herbicides. In the past two years, the northeast state-run farms in our country have used it to control soybean weeds on a large area and have obtained better herbicidal effects.
