Problems solved by technology

Thiophanate-methyl has poor permeability. It has been used for many years and has developed strong resistance. The effect on the control of fruit tree rot is not ideal, and the recurrence rate is high.
The currently registered dosage form is 1.8% octoprodil acetate aqueous solution, which cannot form a thin film, cannot protect wounds, cannot prevent the invasion of germs, and can only kill the bacteria of rotten scars

Embodiment 1

[0013] First, 840 grams of polyvinyl alcohol, a film-forming agent, was added into the reaction kettle, and then 42 grams of 30% octocalid mother liquor, 100 grams of auxin sodium compound nitrophenolate, and 18 grams of ethylene glycol were added. After stirring at normal temperature for 2 hours, it was prepared as a fungicidal octochlor smear with a weight of 1000 grams.

Embodiment 2

[0015] First add 840 grams of film-forming agent polyvinyl alcohol into the reaction kettle, then add 40 grams of 30% octocalidin mother liquor, 100 grams of auxin sodium compound nitrophenolate, and 20 grams of ethylene glycol. After stirring at normal temperature for 2 hours, it was prepared as a fungicidal octochlor smear with a weight of 1000 grams.

Embodiment 3

[0017] First, 750 grams of polyvinyl alcohol, a film-forming agent, was added to the reaction kettle, and then 200 grams of 30% octocalid mother liquor, 45 grams of auxin sodium compound nitrophenolate, and 5 grams of ethylene glycol were added. After stirring at normal temperature for 2 hours, it was prepared as a fungicidal octochlor smear with a weight of 1000 grams.

Abstract

The invention provides a smearing preparation for controlling fruit tree rotten disease. The smearing preparation is prepared from the following raw materials in part by weight by the conventional method: 40 to 200 parts of 30 percent Xin bacteria amine mother liquor, 45 to 100 parts of auxin sodium nitrophenolate, 750 to 840 parts of film-forming agent polyvinyl alcohol and 5 to 20 parts of glycol. The invention is characterized in that: the smearing preparation has a broad-spectrum sterilization function, and is low in toxicity, safe, reliable, economical and practical, residue is avoided, and the medicine and rehabilitation are integrated; and the worldwide problem of controlling fruit tree rotten disease is solved.

Description

technical field [0001] The invention belongs to bactericidal pesticides, in particular to a smear for preventing and treating fruit tree rot. Background technique [0002] The law of the incidence of fruit tree rot disease is: the rot bacteria invade the xylem of the tree body from the pruned cuts, ring cuts, frostbite, and insect wounds. During the dormant period of the fruit tree, when the growth weakens, the bacteria begin to infect, causing fruit branches and stems to appear. Sickness, when serious, causes the death of the branches and destroys the garden. The orchard after 8 years has rot. In the prior art, the active ingredients of the smear and paste for preventing and treating fruit tree rot are thirasine and thiophanate-methyl. Arsine is a high-residue pesticide, and its use has been banned by the Pesticide Control Institute of the Ministry of Agriculture in 2009. Thiophanate-methyl has poor permeability and has developed strong resistance after years of use. The...
