36个农药单剂和33个混配农药的稳定性

Study on Stabilization of 36 Insecticides and 33 Pesticide Mixtures

研究了33个混配农药和32个农药单剂,在54±2℃贮存14d的热贮稳定性试验,以及4个农药单剂常温贮存的稳定性试验。结果表明,混剂中大部分农药成分的稳定性不如其单剂稳定。例如,高效氯氟氰菊酯单剂热贮是稳定的,但是在与吡虫啉混配时,高效氯氟氰菊酯的分解率为61.07%;阿维菌素与毒死蜱混配时,阿维菌素热贮分解率为100%,但是阿维菌素的单剂热贮也是稳定的。

Heat stability of 33 pesticide mixtures and 32 insecticides has been studied in athermostat at 54℃ for 14 days and 4 pesticides at normal atmospheric temperature. Results show that stabilization of most active ingredients of the mixtures was worse than their single formulation. For example, Lambda -cyhalothrin preparation is stabile, but the decomposition values of Lambda -cyhalothrin were 61.07% in the mixture of lambda -cyhalothrin andimidacloprid. Abamectin preparation is stabile, but the decomposition values of abamectin were 100% in the mixture of abamectin and chlorpyrifos.
