Green pure plant insecticide

Abstract

The invention relates to an agronomic crop pesticide adapted for wheat, maize, cotton, vegetable and fruit tree, which is prepared from pinellia tuber, tobacco leaves, moleplant seeds, gelsemium elegans, and cortex acanthopanacis by the weight ratio of 1:1 for each constituent through disintegrating, screening, mixing uniformly, charging industrial alcohol with over 95% concentration and 5-8 times of the total weight of the plant medicinal material, immersing for over 8 hours, concentrating the extracted solvent, the weight ratio of the total weight of the concentrated solution and the total weight of all the plant medicinal total weight is 1:1.

Description

1. Technical field [0001] The invention relates to an insecticide preparation, which is an insecticide made of pure plant medicinal materials. It is suitable for killing insects of various crops such as wheat, corn, cotton, rice and tea, as well as various vegetables, fruit trees and tobacco, especially for killing bollworms, cabbage worms and aphids. 2. Background technology [0002] The existing plant pesticides have low efficacy and small lethality, and generally can only kill about 60% of the pests on the plants. Because this kind of pesticide is steamed at high temperature, the active ingredients in the pesticide are destroyed. In addition, this process is used to produce Pesticides extract less effective ingredients, destroy some plant elements, and greatly reduce the efficacy. Moreover, the production cost of this process is high. Because the distillation needs to increase equipment such as boilers, the price of the product is high and the use cost is increased. 3. ...
