Gelling agent for prevention and treatment of apple tree diseases and preparation method thereof

Abstract

The invention discloses a gelling agent for prevention and treatment of apple tree diseases and a preparation method thereof. The gelling agent comprises the following components in percentage by mass: 0.1-10% of carbendazim, 0.01-0.5% of a wound healing agent, 3-10% of a binder, 0.1-10% of a wetting dispersant, 1-10% of a brightening agent and the balance of distilled water. The preparation method comprises the following steps: weighing and taking active ingredients carbendazim, the wetting dispersant, the brightening agent and the distilled water according to the measuring requirement of the formula, fully wetting and stirring uniformly, adding the mixture into a sand mill for sanding, discharging into a mixing kettle, adding the wound healing agent, the binder and the rest of the distilled water, mixing uniformly to obtain the gelling agent. According to the gelling agent for prevention and treatment of apple tree diseases and the preparation method thereof, provided by the invention, the low-toxicity medicaments are taken as the active ingredients and have an obvious prevention and control effect on valsa ceratosperma of apple trees; besides, a layer of uniform medicinal film is formed at wounds of the apple trees after the gelling agent is used, the ventilation effect is good, autonomous respiration of apple trees is not influenced, wound infection of apple trees caused by exotic germs can be effectively reduced, the rain washing resisting performance is improved, and the effective duration is prolonged.

Description

technical field [0001] The invention relates to a gel used for preventing and treating apple fruit tree diseases, in particular to a carbendazim gel used for preventing and treating apple fruit tree diseases, and in particular to a preparation method of the carbendazim gel. The invention belongs to the technical field of pesticides. Background technique [0002] Carbendazim belongs to the class of benzimidazole fungicides, is a systemic fungicide with high efficiency and low toxicity, and has systemic therapeutic and protective effects. Carbendazim has a wide bactericidal spectrum and has good control effects on diseases caused by various fungi. It can be used for foliar spray, seed treatment and soil treatment. Its mechanism of action is to interfere with the formation of the spindle in the mitosis of pathogenic bacteria, affect cell division, and play a bactericidal effect. [0003] Apple tree rot is a devastating disease that mainly harms the main trunk and main branche...

Problems solved by technology

The rot pathogen has the characteristics of latent infection. Once the conditions are suitable, the bark of the infected part will quickly rot and necrosis. In severe cases, it will lead to dead trees and even damage to the garden, causing huge economic losses and seriously restricting the sustainable development of my country's apple industry.

[0004] At present, no effective cultivars resistant to apple rot have been found, and the pathogen can infect and lie latent from the xylem of the host. Spraying chemical agents cannot make effective contact between the agent and the pathogen, making it difficult to effectively control the occurrence and damage of apple rot.

In recent years, it has been reported that the fungicides are diluted, scraped and dried to prevent apple rot, but the direct dilution and brushing of the fungicides will easily lead to rapid loss of the liquid, not resistant to rain erosion, low local concentration of the drug, and short duration of the drug effect.
