Abstract

The invention provides a pesticide composition containing alkaloids and application thereof, belonging to the technical field of natural pesticides. The pesticide composition containing the alkaloids is characterized by containing following substances by weight percent: 3%-25% of active components, 60%-90% of a solvent, 1%-11% of an emulsifying agent and 2%-13% of a coalescing agent. The pesticide composition containing the alkaloids takes the purely-natural alkaloids as the active components; in the preparation process, a certain ratio of the coalescing agent is added so that the pesticide can be stuck and covers insect body walls for a long time to achieve the good effect of killing insects. The pesticide has the very strong killing effects on the insects including tetranychus cinabarinus boisdu, aphids, plutella xylostella, empoasca flavescens, rice planthoppers and the like and can effectively reduce financial loss caused by insect attacks of crops; meanwhile, the prepared pesticide is good in effect, fast in effect taking speed and long in lasting period, is natural and has no residue, and has good environmental compatibility. The cost is low and a production and processing method is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of natural insecticides, in particular to an alkaloid-containing insecticide composition and its application. Background technique [0002] Plants are a natural treasure house of biologically active substances, and finding insecticidally active substances from plants to research and develop biologically derived insecticides is an important way to create pesticides. [0003] With the enhancement of people's awareness of environmental protection, long-term use of traditional chemically synthesized pesticides has attracted public attention to environmental protection, ecological balance, human, animal and beneficial organism poisoning. At present, many highly toxic, high residue and persistent pesticides have been banned. People's understanding of pesticides has also undergone profound changes, and the concept of "environmentally harmonious pesticides" has been widely recognized by people. The pest control ag...
