Environment-friendly insecticide and application thereof

Abstract

The invention provides an environment-friendly insecticide, which is prepared from the following components by mass percent: 0.1-40% of thiamethoxam, 50-78% of holly essential oil, 5-30% of neem oil, 1-10% of an emulsifying agent and 0.1-0.8% of an antioxidant. The insecticide prepared by effectively combining neonicotinoid insecticides, the neem oil and the holly essential oil can be used for controlling pests, and has a killing effect specially for the common pests such as aphids, thrips, scale insects and tetranychus mites on Chinese orchid; head oil and the tail oil of the plant essential oil are used for replacing a toxic organic solvent used in the preparation process of emulsifiable concentrate, and so that the cost of the pesticide is lowered. The plant essential oil is rapidly and thoroughly degraded in the environment, is free from residue, has no pollution to the environment, and can improve the pesticide activity and reduce pesticide consumption; furthermore, the plant essential oil is mixed with the neem oil, so that the absorption and conduction effects of the Chinese orchid for the insecticide are better promoted, and a synergistic effect for the thiamethoxam is achieved.

Description

technical field [0001] The invention belongs to the field of insecticide technology, and more specifically relates to an environment-friendly insecticide and its application. Background technique [0002] Thiamethoxam is a neonicotinoid insecticide developed by Novartis in 1991. It is the second-generation neonicotinoid insecticide after imidacloprid. It has contact, stomach toxicity and systemic activity. It is an organic phosphorus, organic Good alternatives to chlorine and pyrethroid pesticides. At present, Thiamethoxam has more than ten kinds of pesticide production formulations. In the production process from the original drug to its emulsifiable concentrate preparation, there are many factors that fail to meet the safety and environmental protection standards. Although thiamethoxam EC has the advantages of simple manufacture, easy measurement, relatively uniform distribution of active components on target crops, and relatively high biological activity, the disadvanta...
