在杀虫剂混配制剂(简称混剂)筛选过程中,常遇到如何评价配制药效问题。许多科学家提出某些表达式来衡量混剂是增效、相加、拮抗等作用,为筛选新品种提供依据。 我们根据S.Sakac提出的公式,将它变形后采用图示法快速求出混剂的理论杀虫死亡率。然后按照Mansour等人提出的协同毒力指数值(即C.f.值)来估计混剂是增效作用,还是拮抗现象。 In the pesticide mixture preparation (referred to as mixture) screening process, often encountered how to evaluate the formulation efficacy problems. Many scientists put forward some expressions to measure the mixture is synergistic, additive, antagonistic and other effects, to provide a basis for screening new varieties. According to the formula proposed by S. Sakac, we deform it and use the graphical method to get the theoretical insecticidal mortality rate of mixture. The synergistic toxicity index (ie, C.f. value) proposed by Mansour et al. Is then used to estimate whether the cocktail is synergistic or antagonistic.
