Comparison of Insecticidal Efficacy of Commonly Used TCM Pesticides and Preliminary Research on Compatibility
摘要
Abstract
Objective To lay the foundation of new botanical pesticides by screening the insecticidal efficacy of 10 commonly used TCM pesticides.Methods Slide immersion method, trace intravenous drip method and insect body dipping method were respectively used to measure contact action of water extract and ethanol extract of the 10 commonly used TCM pesticides toTeranychus cinnbarinus,Brevicoryne brassicaeandMythimna separate, with herbal extracts to three kinds of insect pests of corrected mortality as observation indexes,Results Alcohol extracts for three kinds of insect pests were found to have contact action, and water extracts had no obvious effect. The Stemonae Radix alcohol extract had obvious contact action on three kinds of insect pests, and corrected mortality rates were 78.7%, 85.9%, and 96.7%, respectively; ethanol extracts of Angled Bittersweet, Sophorae Flavescentis Radix, Xanthii Fructus and Kansui Radix showed good contact action to Teranychus cinnbarinus,. The volume ratio of compatibility among Angled Bittersweet, Sophorae Flavescentis Radix, Xanthii Fructus and Kansui Radix was 2:1:1.5:1.5:1.5:1.5. The insecticidal activity to Teranychus cinnbarinus, was stronger than extracts of single herbs, and corrected mortality was 96.5%. Alcohol extracts of Stellera, hellebore, white mustard seed, and Xanthii Fructus showed good contact action toBrevicoryne brassicae. When the volume ratio of compatibility among Xanthii Fructus, Stemonae Radix, Stellera, and hellebore was 1:1.5:2:2, the activity toBrevicoryne brassicae increased. and corrected mortality was 93.1%.Conclusion The insecticidal activity will be enhanced after TCM extracts are under compatibility.关键词
