本世纪四十年代,H.B.Tukey和Celia Kirby等成功地合成和生产了苯氧基类化合物(例如2,4-滴),开始了现代杂草防除技术的发展。新除草剂的研究和开发以及被农民接受到如此迅速发展是其他农业技术发展所不及的。 下面按时间先后介绍一些有代表性的除草剂品种。 陶氏公司等的苯氧基类除草剂是一类重要的除草剂,实际上几乎在农业、林业和非农用的各个领域内广泛使用,在它们最初使用后50年仍在销售和使用。 在苯氧基类除草剂以后,曾短期出现过取代基二硝基苯酚类除草剂,如陶氏公司的用作
In the 1940s, H.B. Tukey and Celia Kirby successfully synthesized and produced phenoxy compounds (such as 2,4-D), and began the development of modern weed control technologies. The research and development of new herbicides and their rapid development by farmers are beyond the reach of other agricultural technologies. Here are some representative varieties of herbicides introduced in chronological order. Dow’s phenoxy herbicides are an important class of herbicides that are practically used in almost all areas of agriculture, forestry, and non-agricultural use, and are still sold and used 50 years after their initial use. After a phenoxy herbicide, short-term dinitrophenolic herbicides, such as those used by Dow, have appeared.
