Abstract

The invention discloses a thrips-killing plant essential oil composition, a preparation and an application thereof. The thrips-killing plant essential oil composition contains wintergreen oil and origanum oil, and the weight ratio of wintergreen oil to origanum oil is 1:6 to 6:1. The composition disclosed by the invention can prevent and control thrips, has an obvious synergistic effect, is not easy to generate drug resistance, can improve the capability of the immune system of a crop, can remarkably improve the vitality of the crop, and is a pollution-free plant-derived thrips prevention andcontrol agent which is safe to human beings and animals and has no pollution to the environment.

Description

technical field [0001] The invention relates to a preparation method in the technical field of pesticides, in particular to a thrips-killing plant essential oil composition, preparation and application thereof. Background technique [0002] Thrips is a general term for insects of the thrips family (Thripida) in the order Thysanoptera. It is small in size, strong in concealment and fast in reproduction. So far, there are more than 2,000 species of Thrips family recorded in the world, belonging to about 276 genera of 4 subfamilies, and China accounts for 315 species of 79 genera. According to incomplete statistics, thrips pests account for about 1% of the recorded species. Herbivorous thrips are the main species. The damage caused by feeding, laying eggs or transmitting viruses and the damage caused by the transmission of viruses far exceeds the direct damage. Thrips mainly damage a variety of grains, fruits and vegetables, flowers and gardening. In recent years, the occurr...
