[0024] (1) Take 200mL turbid liquid type veterinary florfenicol liquid (3.6g / 10mL), dissolve it in a water bath at 60°C, add 100mL veterinary gentamicin (100,000 units / 10mL), and 10g of 98wt % streptomycin sulfate for animals and the diethyl diethyl hexanoate of 8g, and dilute with 150kg water, stir, obtain bactericidal medicinal liquid;

[0025] (2) After the plants cultivated in the solar greenhouse get canker, water the plants thoroughly before spraying, and choose to spray the bactericidal liquid prepared in step (1) at 9:00 am to 11:00 am on a sunny day. The amount is 45kg; seal the greenhouse tightly after spraying, wipe the film of the greenhouse with a dry cloth or sponge to remove dust, so as to improve the light transmittance of the film; The temperature drops to 32°C;

[0026] (3) Three days after the first spraying in step (2), continue to spray the plants that are suitable for canker disease according to step (2) and keep the shed covered. After cooling down to 3...

Embodiment 3

[0029] (1) Take 200mL turbid liquid type veterinary florfenicol liquid (3.6g / 10mL), dissolve it in a water bath at 55°C, add 100mL veterinary gentamycin (100,000 units / 10mL), 8g of 98wt % veterinary streptomycin sulfate and 9g diethyl diethyl ethyl, and diluted with 150kg water, stir, obtain bactericidal liquid;

[0030] (2) After the plants cultivated in the solar greenhouse get canker, water the plants thoroughly before spraying, and choose to spray the bactericidal liquid prepared in step (1) at 9:00 am to 11:00 am on a sunny day.

Abstract

The invention discloses a prevention method for plant bacterial canker. The prevention method comprises the following steps of taking and dissolving veterinary-use florfenicol liquid under a water bath condition, adding veterinary-use gentamicin, 98% veterinary-use streptomycin sulphate and diethyl aminoethyl hexanoate, diluting with 15kg of water, and evenly stirring to obtain bactericide liquid; after a plant cultivated in a sunlight greenhouse suffers from the bacterial canker, thoroughly watering the plant before the bactericide liquid is sprayed, spraying the bactericide liquid in a sunny day, sealing the greenhouse after the bactericide liquid is sprayed, cleaning the greenhouse film of the greenhouse with dry cloth or a sponge for removing dust, improving the indoor temperature of the sunlight greenhouse to 53-55DEGC, and then, closing the greenhouse; repeatedly spraying the bactericide liquid, and closing the greenhouse one time; after water is added into the bactericide liquid to carry out dilution, carrying out root irrigation on the plant suffering from the bacterial canker. The prevention method has the advantages of scientific compatibility, good sterilization effect and obvious effect on preventing and curing diseases including plant bacterial canker, so that the plant is free from the infringement of bacteria in a whole growth process and does not generate drug resistance.

Description

technical field [0001] The invention relates to a method for preventing and treating plant bacterial canker. Background technique [0002] Plant canker is a bacterial disease caused by the infection of Corynebacterium michigani, which mainly invades through plant wounds, overwinters on seeds and diseased residues, and can survive for 2 to 3 years. It is prone to disease in humid or insufficient light environment. When cultivating in the open field, the incidence of plant canker is more serious in dog days, rainy or cloudy seasons. When cultivated in a solar greenhouse, the disease is likely to be more serious during early spring cultivation. Early spring cultivation is generally from June to July, when the temperature and humidity are high, the shed film is aging, and the light transmittance decreases, providing a favorable environment for the onset of plant bacterial canker. The pathogenic temperature limit of the pathogen is 1°C to 33°C, and the optimum temperature is 25...
