氟乐灵为目前国外大量应用的优良大豆除草剂。为使这种除草剂能在国内广泛应用,根据国外有关文献,以及我们和各单位的试验和应用结果,作如下介绍。 氟乐灵国外通用名称Trifluralin,商品名Treflan,和Treficon。氟乐灵系由美国的Elanco Products公司于1959年发现。1960年Elililly公司报导了2,6—二硝基苯胺的除草活性并合成了氟乐灵。该品种由于具有杀草范围广,除草效果高,用药量低,使用方便,对作物安全,对人畜低毒等优点,发展很快。1973年成为美国八大吨位农药品种之一,年产原药达1.25万吨。本品种在英国、意大利、苏联等国均已投产,成为目前世界各国应用最广泛的除草剂品种。
Trifluralin is currently used abroad for a large number of good soybean herbicides. In order to make this kind of herbicide widely used in China, the following introduction is made based on the relevant foreign literature, as well as the test results and the application results of us and each unit. Trifluralin commonly used foreign names Trifluralin, trade name Treflan, and Treficon. Trifluralin was discovered by Elanco Products in the United States in 1959. In 1960, Elililly Company reported the herbicidal activity of 2,6-dinitroaniline and synthesized trifluralin. Due to its wide range of herbicides, high herbicidal effect, low dosage and convenient use, the variety develops rapidly with the advantages of crop safety, low toxicity to humans and animals. In 1973, it became one of the eight largest tonnage pesticide varieties in the United States, with an annual output of 12,500 tons of crude drug. The varieties in the United Kingdom, Italy, the Soviet Union and other countries have been put into operation, becoming the most widely used varieties of herbicides in the world.
