Problems solved by technology

Pruning of trees and man-made wounds of tree trunks often use healing ointment for rapid wound healing, especially for the holes formed by chemical injection in trees. It only solves the problem of wound healing, but it is often used for eubacterial infection, and fungicides can only be sprayed, and cannot disinfect tree holes

preparation example Construction

[0028] The preparation method of described modified chitosan comprises the following steps:

[0029] (1) Diquaternary ammonium salt containing imidazole heterocycle: add epichlorohydrin to the reactor, heat up to 75°C, slowly add long-chain alkyl tertiary amine dropwise, after the dropwise addition, stir for 0.5h, cool down to 55°C, Add acetonitrile, then add 1-hydroxyethyl-2-methyl-5-nitroimidazole in 3 times, keep warm for 8 hours, cool down to room temperature, concentrate under reduced pressure to obtain a crude imidazole-containing heterocyclic bis-quaternary ammonium salt, add acetone Stir for 0.5h, concentrate under reduced pressure to obtain a heterocyclic diquaternary ammonium salt containing imidazole; The molar ratio of imidazole is 1:0.64:0.7; the weight ratio of the epichlorohydrin to the acetonitrile and the acetone is 1:6:4;

[0030] (2) Modified chitosan: add chitosan, mass fraction in reactor and be 2% acetic acid solution, stir 1h described chitosan and desc...

Abstract

The invention provides a plant bactericide composition which contains the following components: 1-50 parts of a plant growth regulator, 1-80 parts of a bactericide, 1-30 parts of an insecticide, 80-100 parts of a filming agent, 1-50 parts of a nutrient agent, 0.05-0.5 part of modified chitosan and 1-150 parts of water, wherein the modified chitosan is a chitosan grafted biquaternary ammonium saltwith an imidazole heterocyclic ring; the biquaternary ammonium salt with the imidazole heterocyclic ring is prepared from raw materials, namely 1-hydroxyethyl-2-methyl-5-nitroimidazole, epichlorohydrin and long-chain alkyl tertiary amine; and the weight-average molecular weight of the modified chitosan is 1000-5000.

Description

technical field [0001] The invention relates to the technical field of promoting plant wound healing, in particular, the invention relates to a plant fungicide composition and a preparation method thereof. Background technique [0002] As one of the components of the agricultural economy, the forest and fruit industry usually paints machine oil, paint, lime water, fungicides, etc. on the wounds caused by tree pruning or mechanical damage during production. Some do not take any protective measures, and some mechanical wounds It is difficult to heal through the callus of the tree itself, and the mechanical wound also makes it easier for germs to invade the tree, leading to the occurrence of various diseases, and eventually causing the tree to weaken and even die. [0003] Fungicides are often used to prevent and control fungal diseases of plants, and the method of use is foliar spraying. Pruning of trees and man-made wounds of tree trunks often use healing ointment for rapid ...
