Acer mono maxim brown patch composite reagent and preparation method thereof

Abstract

The invention relates to an acer mono maxim brown patch composite reagent, which comprises clove, Rhizoma Menispermi, Radix Phytolaccae, folium artemisiae argyi, Rhizoma Bolbostemmae, Tagetes patula, copper sulfate, quicklime and chlorothalonil wettable powder. The preparation method of the composite reagent includes: firstly grinding the Chinese medicinal ingredients into fine powder, using ethanol to extract effective ingredients, and then mixing the extract with copper sulfate, quicklime, chlorothalonil wettable powder and water uniformly to obtain a finished product. The effective substances extracted from all the traditional Chinese medicines cooperate with a Bordeaux mixture and chlorothalonil wettable powder to effectively control brown patch. Also, the composite reagent is mainly based on Chinese medicinal ingredients, has low residue, and has small ecological influence on the surrounding environment.

Description

Technical field [0001] The present invention belongs to the technical field of Chinese maple planting, in particular to a compound medicine for the brown spot disease of Chinese maple and a preparation method thereof.

Deep-rooted, medium growth rate, leaves turn bright yellow or red in autumn, can be used as garden trees, street trees and landscape forests. Pentagonal maple has fewer pests and diseases. The brown spot is a fungal disease. When it occurs, the lower leaves begin to develop and gradually spread upward. The initial stage i...

AI Technical Summary

Problems solved by technology

There are few diseases and insect pests of maple pentagon, among which the brown spot is a fungal disease. When the disease occurs, the lower leaves begin to develop and gradually spread upward. The initial stage is a round or oval purple-brown spot, and the later stage is black, causing the leaves to die and fall off. Often a large amount of chemical agents are used, but long-term use of a single agent not only increases resistance, but also causes damage to the surrounding ecological environment
