Multiple Integrated Control Methods of Citrus Leaf Miner

Abstract

The invention relates to a multi-integrated control method for phyllonistis citrella. The method is used for comprehensive control from the aspects of biological control, physical control, agricultural control, chemical control and the like; summer shoots and autumn shoots grow uniformly through rational scientific fertilization; when the summer shoots or the autumn shoots grow to 1-2 centimeters,three schemes are used together for control; a 500-time solution of 30% tolfenpyrad, a 500-time solution of thiocyclam and a 1500-time solution of a nano net-structure pesticide retarder are selected, or a 500-time solution of dinotefuran, a 500-time solution of profenofos and a 1500-time solution of the nano net-structure pesticide retarder are applied, or a 500-time solution of 20% emamectin benzoate.pyriproxyfen and a 1500-time solution of the nano net-structure pesticide retarder are applied; and sex pheromone is suspended in a citrus garden for attracting and killing phyllonistis citrella. The agent form of cream or powder is avoided for the pesticide in the method for avoiding pesticide harm; the pesticide spraying is uniform and thorough, especially for tenders; and the spraying iscarried out until liquid drops from leaves.

Description

technical field

[0001] The invention relates to the field of agricultural pest control, in particular to a multiple integrated control method for citrus leaf miner. Background technique

[0002] Citrus leafminer insect name, belongs to Lepidoptera, leafminer family (Phyllocnistis citrella), is distributed in all continents of the world and my country's citrus producing areas. In my country, Jiangxi, Jiangsu, Fujian, Zhejiang, Hainan, Guangxi, Guangdong, Hunan, Hubei, Guizhou, Sichuan, Chongqing, Shanghai, Yunnan and other areas can occur in citrus gardens. Harm citrus, kumquat, lemon, February orchid, tangerine, quater, rock sugar orange and other plants. is a serious citrus pest. Leaf miner larvae damage young buds and leaves, and in some cases, they can damage fruits. The larvae burrow beneath the leaf epidermis to feed on the mesophyll tissue, creating a meandering tunnel and leaving a fecal thread in the middle. Therefore, there are common names such as ghost drawing...

Embodiment 1

[0021] The multi-integrated prevention and control method of citrus leafminer, this method is comprehensive prevention and control from biological control, physical control, agricultural control, chemical control, etc., and its specific steps are as follows:

[0022] Biological control: when pests occur, the method of using insects to control insects is used to introduce natural enemies of leaf miners;

[0023] Physical control; arranging leafminer sex attractants in citrus planting areas for trapping and killing;

[0024] Agricultural prevention and control: control the planting density of citrus to 100 plants per mu, carry out reasonable fertilization management on the root system of citrus to control the neatness of citrus shoots, and apply different amounts of nitrogen fertilizers to the roots corresponding to different regions of citrus shoots, make it neatly drawn;

[0025] Chemical control: when the summer shoots or autumn shoots are neatly drawn to 1-2 cm, use a mixtu...
