Abstract

The invention relates to a plant protective agent as well as a preparation method and application thereof. The plant protective agent comprises active pharmaceutical ingredients and an auxiliary agentin a mass ratio of 2:3 to 3:1. The active pharmaceutical ingredients comprise, by mass, 20-45% of a Chinese pulsatilla root extract, 10-30% of a chloranthus japonicus extract, 15-25% of a Clematis armandii extract, 12-25% of an extract of Anemone tomentosa (Maxim.) Pei and 10-20% of an extract of Euphorbia lathyris. The plant protective agent provided by the invention has an insecticidal effect of 97% or above on pine caterpillars, and has the same pesticide effect as that of 2.5% deltamethrin as a pesticide; the positive protection effect is achieved on larch forest belts in Qinling Mountainforest areas; the lethality of the plant protective agent on natural enemy insects of the pine caterpillars, namely Telenomus dendrolimusi Chu, is far less than that of a pesticide; besides, the rawmaterials of the plant protective agent are all from rich plant resources in Qinling Mountain regions, the raw materials are easy to obtain, the residual effect period of the plant protective agent isshort, and damage to the Qinling Mountain ecological environment is small.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and specifically relates to a plant protection agent, a preparation method and an application thereof. Background technique [0002] The Qinling Mountains belong to the warm temperate deciduous broad-leaved forest zone and the north subtropical evergreen deciduous broad-leaved mixed forest zone. The forested area accounts for 54% of the total forested area in Shaanxi Province. It is the largest and most important forest area in Shaanxi Province; most of them are secondary forests , Primitive forests are mainly distributed in Taibai, Zhouzhi, Foping, Ningshan and other counties in the sparsely populated and inconvenient high mountainous areas. The Qinling Mountains are huge, with complex natural conditions, and the settlers are rich in animal and plant resources. The larch forest belt in the Qinling forest area of ​​Shaanxi is one of the main forest belts in the Qinling Mountains. The ty...
