最近几年来在应用昆虫学领域中对於用有机合成杀虫剂拌种的方法来保护农作物幼苗免受虫害的研究已经引起了很大的注意。 目前,这种方法已可适用於防治棉花、甜菜、谷类及其他作物的害虫。播种前的种子处理不但可避免幼苗受地下害虫(金针虫、蛴螬)的为害,同时也可免於为害植物地上部分的害虫的为害。後一种情况是由於这类有机杀 In recent years, research on the protection of crop seedlings from insect pests in the field of applied entomology for seed dressing with organic synthetic insecticides has attracted a great deal of attention. At present, this method has been applied to control pests of cotton, sugar beet, cereals and other crops. Seed treatment prior to sowing will not only prevent the seedlings from being damaged by underground pests (golden worms, slugs), but may also be free from pests that injure the aerial parts of the plants. The latter situation is due to such organic kill
