Smearing preparation for preventing and controlling kiwifruit bacterial canker

Abstract

The invention relates to a smearing preparation, in particular to a smearing preparation for preventing and controlling kiwifruit bacterial canker. Bromothalonil as a low-toxicity medicament is used as an active ingredient of the smearing preparation, and smearing is used as the using way of the smearing preparation, so that no liquid medicine drifting problem exists. More importantly, the smearing preparation provided by the invention is a gel liquid and can automatically form a uniform coating at the wound part of a kiwifruit after being used, so that infection of foreign germs to a wound of a plant and water evaporation of the plant can be effectively reduced, influences of the wound to the growth of the kiwifruit can be reduced, and the aims of preventing and controlling the kiwifruitbacterial canker for a long term can be achieved.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a smear, more particularly to a smear for preventing and treating kiwi fruit canker. technical background [0002] Kiwifruit canker is a devastating bacterial disease that seriously threatens the production of kiwifruit. It can infect different parts of kiwifruit, harm the branches and flower buds of kiwifruit, and cause symptoms such as flower rot, dead leaves, and dry branches above the ground. Kiwifruit canker develops rapidly and has a high frequency of prevalence. Some affected orchards are almost destroyed, causing heavy economic losses to fruit farmers. [0003] At present, the prevention and treatment of kiwifruit canker is mainly based on the prevention of chemical agent spraying, and the commonly used agents are agricultural streptomycin and kasugamycin. However, the spraying method is often used in the application method, which cannot effectively contact the agent wit...

Problems solved by technology

However, the spraying method is often used in the application method, which cannot make the effective contact between the agent and the fungus, resulting in poor control effect, and can not achieve the purpose of effective prevention and control of the disease.

In recent years, there have been reports of using fungicides to dilute and then scrape and apply dry to prevent and treat kiwifruit canker. This method of application makes the agent directly contact with the fungus, which is easy to exert the effect of the drug, but the direct dilution and application of the agent will easily lead to the rapid loss of the drug solution. Not resistant to rain erosion, low local drug concentration, short duration of drug effect, poor stability and many other problems
