Prevention and treatment method of apple tree virus diseases

Abstract

The invention discloses a prevention and treatment method of apple tree virus diseases. When apples start to germinate, branches of apple trees are smeared with mixed disinfectant once every 5-7 days for 2-4 times continuously in total, wherein the smearing range includes the branches which are 150 cm high or below. The mixed disinfectant is prepared from, by weight, 12-18 parts of ribavirin injection, 8-12 parts of vitamin C, 8-12 parts of zinc sulfate, 12-18 parts of calcium nitrate, 8-12 parts of potassium sulphate, 25-35 parts of brown sugar, 0.5-2 parts of organosilicon compound and 2400-3600 parts of water. The symptoms of diseased plants can be rapidly eliminated after about three times of smearing, the normal fruiting of the fruit trees at the current year can be ensured, and economic loss is avoided.

Description

technical field [0001] The invention relates to the field of apple cultivation, and more specifically, the invention relates to a method for preventing and treating viral diseases such as mosaic disease and rust disease of apple trees by using a mixed disinfectant. Background technique [0002] The common viral diseases in apple cultivation mainly include apple mosaic disease, rust fruit disease, etc. These viral diseases not only directly affect the yield and quality of apples, but also have strong transmissibility. Strain disease, and as long as the host still exists, the virus will survive and reproduce continuously, and can form new diseased plants through grafting, pollen, etc., especially mosaic disease can slowly spread throughout the orchard under natural conditions Spread, causing great losses to fruit growers. However, at present, there is no effective control method for viral diseases such as apple mosaic disease and rust disease. Generally, as long as the fruit ...

[0002] The common viral diseases in apple cultivation mainly include apple mosaic disease, rust fruit disease, etc. These viral diseases not only directly affect the yield and quality of apples, but also have strong transmissibility. Strain disease, and as long as the host still exists, the virus will survive and reproduce continuously, and can form new diseased plants through grafting, pollen, etc., especially mosaic disease can slowly spread throughout the orchard under natural conditions Spread, causing great losses to fruit growers

However, there is currently no effective control method for viral diseases such as apple mosaic disease and rust disease. Generally, as long as the fruit tree is susceptible to disease, the method of planing the tree can only be adopted to avoid its spread, causing heavy economic losses.
