Embodiment 1

[0058] Example 1 The preparation of the pesticide composition containing Artemisia capillary and rhubarb extracts of the present invention

[0059] a. Extraction: Weigh Artemisia capillaris, remove impurities, wash, slightly moisten, dry, weigh rhubarb, remove impurities, wash, moisten thoroughly, dry, mix Artemisia capillaris and rhubarb, crush, and pass through a 80-mesh sieve , add solvent, reflux extraction twice, filter, combine the filtrate, concentrate, make the weight of the extract equal to the weight of the original medicinal material, and obtain the extract bq-01~bq-06; wherein, the parameters are shown in Table 1;

[0060] b. Preparation: add the additives in Table 2 to the extracts bq-01-bq-06, and stir evenly to obtain the pesticide compositions BQ-01-BQ-06 containing the extracts of Artemisia capillary and rhubarb.

Abstract

The invention relates to a pesticide composition containing extracts of artemisia capillaris and rheum officinale and a preparation method and application thereof, belongs to the field of pesticides, and provides the pesticide composition containing the extracts of the artemisia capillaris and the rheum officinale in order to solve the technical problem. Active components of the pesticide composition containing folium isatidis and the rheum officinale extract are extracted from the following raw medicinal materials in parts by weight: 10 to 30 parts of artemisia capillaris and 1 part of rheum officinale. The common extracts of the artemisia capillaris and the rheum officinale have a synergistic effect, and the effect of preventing and treating apple altermaria leaf spot of crops is obvious; by the adoption of the folium isatidis and the rheum officinale extract for joint extraction, the contents of scoparone, leaf rheum emodin and other bacterial active components with main groups basically the same as those in the scoparone and the leaf rheum emodin are increased; the apple altermaria leaf spot is prevented and treated, the immunity system of the crops can be improved, and the activity of the crops can be obviously enhanced; traditional Chinese herbs are used as raw materials, so that pesticide residues are avoided; compared with an independently used chemical-source pesticide, the pesticide composition is environment-friendly; meanwhile, when the pesticide composition is used, the effective concentration is low, and the cost is low.

Description

technical field [0001] The invention relates to a pesticide composition containing wormwood and rhubarb extracts, a preparation method and application thereof, and belongs to the field of pesticides. Background technique [0002] Artemisia capillary is a perennial herbaceous plant belonging to the genus Artemisia in the Asteraceae family belonging to the dicotyledonous plants of the angiosperm phylum.
