A tea garden environmental protection insect repelling stick and its production method

Abstract

The invention discloses an environmentally friendly insect repellent stick for tea gardens and a production method thereof. The raw materials of the insect repellent stick are composed of repellent, sodium cocoyl sulfate, lauryl glucoside, polyethylene glycol, gelatin, starch, agar, Disodium hydrogen phosphate buffer, water. In the preparation method, the raw materials of the environmentally friendly insect repelling stick are ground, ultrasonically extracted, vacuum filtered, and pigmented to purify the raw material mixture of the insect repelling stick; then the gel of the insect repelling stick is prepared. The insect stick raw material mixture and disodium hydrogen phosphate buffer solution are stirred by high-speed magnetic force, poured into a polypropylene cylindrical tube for molding, and then cooled to make the insect repellent stick. The invention has the advantages that: the raw materials of the insect repelling stick are all biodegradable, safe and environment-friendly, biological raw materials, and will not cause pollution when discarded in the tea garden. The insect repellent stick has simple manufacturing process, low cost, remarkable control effect and wide market prospect.

Description

technical field [0001] The invention relates to a biological pesticide, in particular to an environmental protection insect repellent stick for tea gardens and a production method thereof. Background technique [0002] The tea leafhopper Empoasca vitis Gothe belongs to the order Homoptera and belongs to the Leafhopper family. It is a common pest in my country's tea areas and the number one pest on tea trees in my country. The insect is small in size, hidden in danger, has many generations, fast reproduction, serious generation overlap, and difficult control. It mainly sucks the buds and leaves of tea trees with adult nymphs, resulting in shrinkage of buds and leaves, red veins, and red leaf tips and margins. Brown scorch, tooth slightly growth stagnation, affecting the yield and quality of tea. In the tea areas in the middle and lower reaches of the Yangtze River in my country, the loss of tea in summer and autumn in normal years is 10%-15%, while the loss of tea in severe ...
