Embodiment 1

[0016] The repellent is prepared, calculated by weight percentage: the active ingredient of the natural repellent is 1.0%, wherein the azadirachtin is 35%, and the natural pyrethrin is 65%. Remix ethanol 20%, C 12 h 24 79%, after uniform mixing and stirring, it was kept in the dark for 5 minutes to obtain the repellent of group A.

Embodiment 2

[0018] Repeat Example 1, with the following differences: adjust the mass percentages of natural pyrethrins and azadirachtin to 60% and 40% respectively, keep the other ingredients constant, mix and stir evenly, and keep still for 5 minutes in the dark to obtain group B repellent.

Embodiment 3

[0020] Repeat Example 1, the following difference is arranged: the active ingredient of natural repellent is 1.2%, wherein azadirachtin 35%, natural pyrethrin 65%. Ethanol 20%, C 12 h 24 78.8%, uniformly mixed and stirred, and kept in the dark for 5 minutes to obtain the C group repellent.

Abstract

The invention discloses a special-purpose repellant for tobacco insect and an application method thereof. The repellant is prepared by uniformly mixing 1.0-1.5% of effective ingredient, 20-30% of ethanol and 68.5-79% of 1-dodecene C12H24. The effective ingredient comprises 35-40% of nimbin and 60-65% of natural pyrethrin. The method comprises the following steps: adding the repellant in a heater, continuously heating under 114-121 DEG C, and then repelling cigarette beetle, ephestia elutella, mosquito, fly, cockroach, bug and spider in a workshop in short time. The special-purpose repellant has the advantages of high insecticidal activity, wide effect scope, less usage amount and no harm on human body. Due to fast repelling speed and short decomposition time, repellant resistance is difficult for insects. The repellant is decomposed to H2O and CO2 in air finally, and can not left in production environment. In the invention, ethanol and carbon 12 can be taken as a synergist, and the repellant has good thermostability.

Description

technical field [0001] The invention belongs to the technical field of removing and killing tobacco pests, and in particular relates to a special repellent for tobacco pests. At the same time, the present invention also relates to a method for using the repellent. Background technique [0002] Common pests in cigarette production workshops and storage warehouses mainly include tobacco beetles, tobacco powder borers, flies, mosquitoes, spiders and cockroaches. Whether these pests bite the tobacco leaves, or the dead bodies and excrement of the pests, they will pollute the tobacco leaves and pose a threat to the sensory quality of cigarettes. Existing deworming products mainly include chemical insecticides and cinnamaldehyde repellents. The traditional chemical insecticides are mainly Liexizhen, which will cause serious drug residue problems during the killing process, which will not only affect the quality of tobacco leaves, but also cause toxic and side effects to the staf...
