由于害虫对农药抗性的出现,在过去70多年的农药商品发展中,农药组合物产品被广泛地推广使用。自从1942年Haller等使用除虫菊与芝麻素组合提高了活性化合物的杀虫活性以来,增效作用的定义即被用于评价杀虫剂不同的作用方式。Metcalf于1967年提出农药组合物增效作用的定义为,以活性效果为基础,使用一种无毒的化学物质与活性化合物组合使用来提高活性化合物的致死率,或者更普遍的理解是提高活性化合物对靶标害虫的防治效果。使用致死中浓度
Due to the emergence of pest resistance to pesticides, pesticide compositions have been widely used in the development of pesticide products for more than 70 years. Since Haller et al. Used a combination of pyrethrum and sesamin in 1942 to increase the insecticidal activity of the active compounds, the definition of synergism has been used to evaluate the different modes of action of insecticides. Metcalf proposed in 1967 that the synergistic effect of a pesticide composition is defined as that based on the active effect, a non-toxic chemical is used in combination with the active compound to increase the lethality of the active compound or, more generally, to increase the activity Prevention and Cure Effects of Compounds on Target Pests. Use lethal concentration
