A Pesticide EC for Controlling Apple Rot

Abstract

The invention discloses pesticide emulsifiable oil for preventing and controlling apple canker. The pesticide emulsifiable oil comprises the following components in percentage by weight: 20%-80% of tridemorph, 10%-60% of vegetable oil and/or esters thereof, 5%-20% of emulsifiers and 0%-5% of penetrants. Compared with tridemorph emulsifiable oil prepared from dimethylbenzene, the emulsifiable oil disclosed by the invention has better properties, i.e. volatility, surface tension, wettability, permeability, and the like, and better effect on the apple canker.

Description

Technical field [0001] The invention relates to a pesticide emulsifiable concentrate preparation, in particular to a tridecanoline emulsifiable concentrate preparation for preventing and curing apple rot. Background technique [0002] Trimorpholine is a broad-spectrum systemic fungicide with dual functions of protection and treatment. It can be absorbed into the plant body through the roots, stems and leaves of the plant, and moves upward in the xylem, but only slightly in the phloem. Transfer. Thirteen morpholine is mainly used to prevent and treat cereal powdery mildew and banana leaf spot disease, and for other fungal diseases, such as: white, red, brown root disease of rubber tree, powdery mildew, coffee eye spot disease, tea and tea cake disease, melon white powder Diseases, etc. also have good preventive effects. Tridecamorpholine EC on the market consists of tridecamorph, xylene and emulsifier. [0003] Apple rot disease, commonly known as skin rot, is an important diseas...

AI Technical Summary

Problems solved by technology

It mainly damages fruiting trees over 6 years old, causing tree vigor to weaken, branches to die, dead trees, and even gardens to be destroyed; the pathogen spreads and survives the winter on the surface of the diseased bark and xylem; currently, thiram is mainly used to prevent and control apple rot, but the agent is toxic Large and poorly effective after years of use

[0004] According to the experimental research, although the tridemorphic emulsifiable concentrate with xylene as the solvent is effective against apple rot, it is better than thiram, but the control effect is still not up to the ideal requirement
