Root composite treating agent for preventing and treating fruit tree root diseases and insect pests, preparation method and application thereof

Abstract

The invention discloses a root composite treatment agent for preventing and treating fruit tree root diseases and insect pests, a preparation method and application thereof. The root composite treatment agent comprises a matrix, a bactericidal active component and an insecticidal active component, wherein the matrix is an interior wall water-based coating material for buildings, the bactericidal active component is a copper ion complex, and the insecticidal active component is one of neonicotinoid insecticides. According to the invention, the root composite treatment agent can be used for preventing and treating fruit tree root diseases and insect pests such as root cancer, southern blight, white streak, root rot, purple streak, round spot root rot, young shoot piercing-sucking type insectpests and the like, and can be used for directly dipping or coating roots after fruit tree seedlings come out of a nursery or before planting; and a protective film layer containing bactericidal andinsecticidal active ingredients can be formed on the root, so that various diseases and pests on the root of the fruit tree nursery stock can be effectively shoveled, the root of the newly planted nursery stock is protected from being damaged by the diseases and pests in the rejuvenation period and the young tree growth period, and the prevention and control level of diseases and pests on the rootof the fruit tree nursery stock can be effectively improved.

Description

technical field [0001] The invention relates to the field of agricultural bactericides and insecticides, in particular to a root compound treatment agent for preventing and controlling fruit tree root diseases and insect pests. Background technique [0002] Root diseases and insect pests are one of the important diseases of fruit trees, including root cancer, white silk disease, white-striped feather disease, root rot, purple-striped feather disease, round-spotted root rot, hairy roots, grubs, aphids, and green Lygus . Among them, root diseases mainly lead to root neck cortex necrosis, root rot, root cancer, hairy roots, etc., which affect root growth, weaken tree vigor, affect the growth of the entire tree, and cause dead trees. Newly planted young trees are particularly affected. Newly planted fruit tree seedlings are very susceptible to bacterial infection due to many root wounds and poor disease resistance. After the roots are infected, they can carry bacteria for life...

AI Technical Summary

Problems solved by technology

However, due to the reasons that the pesticides treated by root dipping or root irrigation are easily absorbed by the soil and have a short duration, these methods cannot achieve the desired effect on the control of root diseases and insect pests, and are rarely used in actual production.

[0007] Therefore, actual production needs root treatment preparations with better control effect and long-lasting effect, and the existing root treatment agents need to be further improved.
