Abstract

A thermocomposing mosquito-repellent table is composed of carrier and the insecticide prepared from pyrethrins, Es-allethrin, synergist and solvent. Its advantages are high and durable effect, and low residue.

Description

technical field [0001] The invention relates to an insecticide, in particular to a solid insecticide used in combination with natural plant insecticides and chemical insecticides. Background technique [0002] Chinese patent application 03117571.6 discloses "an electric heating sheet mosquito-repellent incense and its preparation method". Various components are evenly mixed to make a dripping solution for electric heating mosquito coils, which is dropped into the base paper sheet. Each piece of electric heating mosquito-repellent incense contains 10mg~100mg of pyrethrins, and the single-sided evaporation area of ​​the base paper of each electric heating mosquito-repellent incense is 5cm 2 ~10cm 2 , and then sealed and packaged with aluminum foil composite film, after quality inspection, the required electric heating sheet mosquito coils can be obtained. However, there are problems that the use of pure natural pyrethrins as insecticidal components decomposes quickly in the...
