Mosquito-repellent incense containing bifenthrin for preventing and controlling tea tree pests and preparation method thereof

Abstract

The invention discloses a mosquito-repellent incense containing bifenthrin for preventing and controlling tea tree pests and a preparation method thereof. The incense is a disk type incense, and is characterized by being prepared from the following raw materials in percentage by weight: 65 to 75 percent of carbon powder, 4 to 5 parts of wood flour, 12 to 18 parts of ixonanthes chinensis flour, 8 to 12 parts of starch, 0.3 to 0.7 part of bifenthrin and the balance of water. The preparation method comprises the following steps: fully drying the carbon powder, the wood flour, the ixonanthes chinensis flour and the starch, smashing the mixture, adding water for blending and pulping, then introducing the pulp into an incense maker for bar extrusion under air pressure or compressing molding, anddrying; soaking the dried incense in a bifenthrin solution for 40 hours, taking out and drying with hot air to obtain the mosquito-repellent incense. The mosquito-repellent incense has the advantagesof good prevention and control effects, low pesticide residue, high applying rate, low applying working strength and the like on the basis of basic features of tea trees and the life habit of empoasca flavescens as a target pest, and has important significance to the guarantee of tea quality safety and facilitation of the sustainable development of tea production.
