在当今时代,很多熏蒸性杀线虫剂被禁用、淘汰。有趣的是,正是因为熏蒸性杀线虫剂才使得人们认识到植物寄生线虫对作物危害是多么的巨大。人们早在1743年就发现作物会受到植物寄生线虫的影响,但是直到20世纪40年代,人们才认识到线虫真正的经济危害。当时土壤熏蒸已经发展起来,线虫得到显著控制,并因此获得明显的产量收益。1947年,美国种植业局首席R.M.Salter博士说:“自 In today’s era, many fumigating nematicides are banned and eliminated. Interestingly, it is because fumigating nematicides make people aware of how great plant parasitic nematodes harm crops. As early as 1743, people found that crops were affected by plant parasitic nematodes, but it was not until the 1940s that people realized the true economic harm of nematodes. At that time, soil fumigation had developed and the nematodes were significantly controlled and, as a result, significant yield gains were obtained. In 1947, chief executive R.M.Salter of the U.S. Agency of Planting Industry said: ”
