Problems solved by technology

When pests and diseases break out in a large area, growers often face the dilemma of not being able to hire manpower for pesticide spraying
In addition, the transfer of rural land is accelerating. There are more and more family farms and large planters, and the demand for pest control is increasing. The traditional knapsack sprayer is difficult to meet the needs of large-scale tea tree and sudden pest control.

Abstract

The invention provides an aerial spraying tea tree pest control method and belongs to the technical field of plant pest control. The aerial spraying tea tree pest control method comprises the following steps of selecting an area to be processed in a tea garden, loading an agricultural plant protecting aeroplane with pesticide solution, fixing spray nozzles, adjusting the flow speed of pesticide solution of the spray nozzles, and setting flight speed and height for spraying. The aerial spraying tea tree pest control method controls tea tree pests by placing a manual manner with the agriculturalplant protecting aeroplane to achieve the optimum control effects under the premise of reducing pesticide application, increases control effects on tea pests such empoasca flavescens, tea geometrid and euproctis pseudoconspersa up to 90%, and greatly saves labor cost and pesticide applying time.

Description

technical field [0001] The invention belongs to the technical field of plant pest control, and in particular relates to a method for preventing and controlling tea tree pests by aircraft spraying. Background technique [0002] Leafhoppers, whiteflies, and aphids are the main pests of tea trees. Nymphs or larvae suck tea tree shoot juice and consume tea tree nutrients and water. After the pests have caused damage, the leaf margins of the injured buds and leaves turn yellow and scorched, the veins are red, the growth stagnates and hardens, and even falls off. At the same time, the pests can induce serious diseases, resulting in the intermingling of tea tree diseases and insect pests, loss of nutrients, hindered photosynthesis, weakened tree vigor, thin buds and leaves, and the damaged buds and leaves are fragile, astringent, and the quality of tea leaves is greatly reduced. [0003] For many years, the control of tea tree pests has mainly been carried out by traditional manua...
