Problems solved by technology

[0003] As a main method of biological control, botanical pesticides are also an emerging research field of pest control. They have been applied more and more by experts at home and abroad, and their development is still deepening. However, most of the botanical pesticides have The effect is slow, not quick-acting, and at the same time, the storage stability is poor, and the quality is not easy to control, which leads to the slow development of the industrialization of botanical insecticides

Abstract

The invention discloses a method for manufacturing an environment-friendly insecticide with nerium indicum and radix euphorbiae lantu. The method includes manufacturing nerium indicum extracts, to be more specific, cleaning and airing fresh nerium indicum leaves, cutting the nerium indicum leaves to obtain fragments, drying the fragments in drying ovens, smashing the fragments, mixing the fragments and ethanol with one another to obtain mixtures, then processing the mixtures by the aid of microwave, then soaking the mixtures for 48h, then filtering the mixtures, extracting nerium indicum leaf extracts from the mixtures and carrying out water-bath distillation to recycle the ethanol; manufacturing radix euphorbiae lantu extracts, to be more specific, cleaning and airing fresh radix euphorbiae lantu, cutting the radix euphorbiae lantu to obtain fragments, drying the fragments in drying ovens at the temperatures of 60 DEG C, then smashing the fragments, mixing the fragments and ethanol with one another to obtain mixtures, then processing the mixtures by the aid of microwave, then soaking the mixtures for 50h, then filtering the mixtures, extracting the radix euphorbiae lantu extracts from the mixtures and carrying out water-bath distillation to recycle the ethanol; uniformly mixing the nerium indicum extracts and the radix euphorbiae lantu extracts with one another according to a proportion of 3:1 to obtain mixtures, and then adding antibiotics into the mixtures for preservation.

Description

technical field [0001] The invention relates to an environment-friendly insecticide for oleander chamaejasma, belonging to the field of insecticides. Background technique [0002] As a branch of biological control technology, botanical pesticides are mainly used to control pests by extracting substances that have stomach toxicity, contact killing and fumigation effects on stored grain pests through all or part of biological organisms and their extracts. potion. The active ingredients of botanical insecticides against pests mainly include alkaloids, glycosides, toxic proteins, and organic acids, esters, and ketones. For a long time, experts at home and abroad have done a lot of scientific research and development and application practice in the control of stored product pests with botanical pesticides. According to statistics, there are more than 200 species of plants used for the control of stored grain pests in the world, and more than 30 kinds of tested pests, covering a...
