Abstract

The invention discloses a disinfectant for preventing diseases of branches of fruit trees and a preparation method thereof. The preparation method comprises the following steps of: using water to dissolve humic acid, urea or glycol, monopotassium phosphate, manganese sulfate, zinc sulfate, disodium ethylene diamine tetraacetate, compound sodium nitrophenolate or amino-acyl ester, preservative and aluminium-magnesium silicate, stirring till all the components are dissolved, preparing into solution; crushing thiophonate-methyl, white carbon black and an auxiliary agent which are not dissolved in water to 1000 meshes, adding the obtained mixture into the solution, and evenly stirring, using boiled water to dissolve cellulose or xanthan gum, stirring the mixture to be gelatinous, adding the gelatinous mixture into the solution, shearing and stirring at high speed and then preparing disinfectant of fruit trees. The invention has the advantages of high efficiency, low toxicity, no recurrence, fast wound healing, no settlement and the like, is a preferred disinfectant for preventing fruit branch diseases of apple tree canker, actinidia canker, citrus foot rot, peach tree gummosis disease and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a fungicide for preventing and treating fruit tree branch diseases, and also relates to a preparation method of the fungicide. Background technique [0002] Branch disease is one of the main diseases of fruit trees. In recent years, the occurrence of fruit tree branch diseases has increased year by year. Fruit tree branch diseases mainly include apple tree rot, kiwi fruit canker, citrus foot rot, citrus resinous disease, bayberry branch rot, red clothes disease and cancer swelling, loquat, pear, litchi stem rot and fruit tree flow. Glue disease, etc. Branch and trunk diseases are very harmful to fruit trees, often causing tree vigor to decline, and severe cases will cause fruit trees to die in pieces, which should be paid great attention to by fruit farmers all over the country. At present, the drugs with good effect on the prevention and treatment of fruit tree branches an...
