Embodiment Construction

[0020] The principles and features of the present invention will be described below in conjunction with specific examples, which are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0021] A method for preventing and treating citrus leafminer, comprising the steps of:

[0022] Step S1, frequent weeding and frequent cultivating;

[0023] Step S2, according to the nutrients required by the current growth stage of citrus, timely and sufficient nutrient supply, so as to ensure the resistance of fruit trees;

[0024] Step S3, do a good job of pruning in summer, and take the dead branches and diseased branches away from the orchard in time, which can kill the larvae of the leaf miner; Also do a good job of winter pruning, and seal the trunks with holes in time to ensure the smoothness of the trunks;

[0025] Step S4, avoid planting leafminer host plants around the orchard, such as sycamore, fig, etc.;

[0026] Step S5...

Abstract

The invention relates to a method for prevention and control of phyllocnistis citrella of citrus gonggan trees. The method includes steps: step S1, weeding and intertilling frequently; step S2, timelyand sufficiently supplying nutrients according to nutrient demands of citrus in a current growth stage; step S3, timely removing deadwood and diseased branches out of an orchard, and well carrying out summer pruning and winter pruning; step S4, avoiding planting of phyllocnistis citrella host plants around the orchard; step S5, manually digging eggs in an egg-laying stage of phyllocnistis citrella from May to June and from July to August yearly; step S6, protecting natural enemies of phyllocnistis citrella; step S7, adopting physical means including (1) manually catching in mating of phyllocnistis citrella; (2) checking phyllocnistis citrella emergence holes in tree trunks before and after the Tomb-Sweeping Day, and killing larvae with iron wire hooks; eliminating eggs before and after the Summer Solstice; step S8, adopting chemical means including selecting bifenthrin or efficient lambda-cyhalothrin for prevention and control. The method is environmentally friendly, high in fast-acting effect and persistence in prevention and control of phyllocnistis citrella of citrus gonggan trees and effective in population density reduction and phyllocnistis citrella harm inhibition.

Description

technical field [0001] The invention relates to the field of tribute mandarin planting, in particular to a method for preventing and treating the tribute mandarin leaf miner. Background technique [0002] Leaf miner is a very small moth pest with a body length of only about 2 mm, silvery white, small eggs, oval, flat bottom, white and transparent; larvae are flat, yellow-green, without legs, about 4 mm long The pupa spins cone-shaped, yellowish brown, mainly harming young leaves and twigs, with very slight damage to spring shoots, and severe damage to summer and autumn shoots. In the field of citrus citrus planting, the leafminer damages young buds and leaves, causing winding tunnels, causing the damaged leaves to shrink and fall off easily, and induces the occurrence of canker. Huge economic loss. Contents of the invention [0003] In summary, in order to overcome the deficiencies in the prior art, the technical problem to be solved by the present invention is to provid...
