Problems solved by technology

This method of prevention and control forms new wounds on the tree body, and because the sprayed pesticides are not firmly adsorbed and have poor permeability, they can only prevent the pathogens on the surface of the tree body. bacteria, it is impossible to achieve the effect of prevention and control

Embodiment 1

[0012] Example 1 Spray film agent for sweet persimmon rot

[0013] A kind of sweet persimmon rot spray film agent, the weight parts of every 100 mL raw material components are: 2 parts of sodium carboxymethyl cellulose, 0.5 parts of sodium lauryl sulfate, 4 parts of alkylphenol polyoxyethylene ether, 0.25 parts 25% carbendazim wettable powder, 0.5 part 40% aluminum triethylphosphonate, add water to 100 mL, stir until fully dissolved.

Embodiment 2

[0014] Example 2 A comprehensive control method for sweet persimmon rot

[0015] In the Sanlifan sweet persimmon planting base in Luotian County, Hubei Province, three relatively independent sweet persimmon gardens were selected. In late April 2015, before the persimmon trees bloomed, 20 persimmon trees with basically the same growth and infected with the above-mentioned sweet persimmon rot were selected. For the sick sweet persimmon tree, according to the standard of leaving 10-15 flower buds on long branches, 5-10 flower buds on middle and long branches, and 3-5 flower buds on short branches, remove the excessive flower buds of the sweet persimmon tree, The remaining flower buds are relatively evenly spaced; in early May, after the persimmon tree blooms, remove the sweet persimmon tree in time according to the standard of leaving 10 flower buds on long branches, 5 flower buds on medium and long branches, and 3 flower buds on short branches. Excess flower buds; in early June,...

Abstract

The invention discloses a comprehensive control method for rot of persimmons. By performing control according to different growing periods of the persimmons, the control method comprises the following steps: (1) performing flower thinning and fruit thinning to control the yield of the persimmons; (2) adding a fertilizer to improve the nutritional level of a persimmon tree; and (3) spraying a persimmon rot spraying film agent provided by the invention to the trunk. According to the method, the pathogenic bacterium resistance of the persimmon tree is enhanced; and for a disease plant, the method can ensure the action time of the agent, enhance the permeability of the agent, reduce the external damage to the infected part and improve the control effect.

Description

technical field [0001] The invention relates to the technical field of crop disease and insect pest control, in particular to a comprehensive control method for sweet persimmon rot. Background technique [0002] According to the survey, in Luotian County alone, there are more than 5,000 persimmon trees over 100 years old, and they still have relatively high yields. Sweet persimmons can bear fruit 2 to 4 years after planting, and enter the full fruit period after 5 to 7 years, with an output of more than 2000 kg / mu. Sweet persimmon regenerates fast fruiting, high yield and long life. However, during the cultivation of sweet persimmons, the persimmon trees are prone to stem rot disease. After the persimmon trees enter the fruiting period, due to successive years of fruiting, the tree body consumes a lot of nutrients and the tree body weakens, which is a major cause of the rot disease. Pathogens responsible for the development of rot include several hundred species of soil-bo...
