Pesticide paste for controlling rot disease of fruit tree in northern area as well as preparation method and application method of same

Abstract

The invention discloses a pesticide paste for controlling rot diseases of fruit trees in northern areas as well as a preparation method and a application method of same. The pesticide paste is a semi-solid mixture composed of 20 to 30 parts of yellow clay loam, 15 to 30 parts of urea, 10 to 15 parts of humic acid, 8 to 12 parts of Asomate, 2 to 3 parts of polyvinyl alcohol, 2 to 3 parts of potassium dihydrogen phosphate, 0.003 parts of naphthylacetic acid as plant growth regulator hormone, 0.001 parts of gibberellin as plant growth regulator hormone and water. The control method is proposed to solve the problems in the prior art that the rate of controlling rot diseases of fruit trees in northern China is low, the rot diseases are liable to reoccur and the wounds are hardly healed; and can overcome the deficiencies of conventional pesticides and application.

Description

technical field [0001] The invention relates to a fungicide in the field of pesticides. Background technique [0002] Fruit trees in the north, such as apples, pears, peaches, cherries, etc., during the growth and development period, the bark has cracks or encounters cloudy and wet weather, coupled with sand leakage, soil malnutrition and old orchards for many years, fruit tree rot often occurs. Also known as rotten skin disease, it mainly occurs on the branches and trunks of trees. When suffering from this disease, the tree vigor is weakened and the yield is reduced. In severe cases, the main trunk or main branches are partially withered, and even the whole fruit tree dies. It is called fruit tree cancer, and it is the most headache for northern fruit farmers. In order to cure this disease or alleviate its morbidity, the bark has to be scraped and smeared with fungicides, but it is often a temporary solution rather than a permanent cure. Most of the existing prevention an...

AI Technical Summary

Problems solved by technology

Most of the existing prevention and treatment methods for fruit tree rot are complex formulas or difficult to operate. The trunk and branches are exposed to natural conditions, wind, sun, rain, etc., low utilization rate, large residual toxicity, short drug effect, and frequent use. , the disease is easy to recur, making the existing methods of preventing and treating fruit tree rot more difficult and less effective.
