Embodiment 1

[0021] Tobacco pests described below will be described using tobacco beetles and tobacco meal borers as examples.

[0022] A control method for tobacco pests, comprising the following steps:

[0023] (1) Pharmaceutical preparation: dissolving insect sex pheromone 7-hydroxy-4,6-dimethyl-4-nonen-3-one in methanol at a mass ratio of 1:1000 to obtain insect sex pheromone solution; according to the mass ratio of insect pheromone and inert powder being 1:1000, the insect pheromone solution is atomized and sprayed onto the inert powder, stirred, dried, pulverized, and passed through a 200-mesh sieve to obtain an insecticidal powder;

[0024] (2) Spray pesticides and kill insects: Use a duster to spray the above-mentioned insecticide powder. Before starting the powder spraying, you must close all the doors and windows of the warehouse to avoid the loss of the pesticide;

[0025] The amount of spraying is determined according to the following formula: spraying amount = unit spraying a...

Embodiment 2

[0028] The difference with embodiment 1 is:

[0029] A control method for tobacco pests, comprising the following steps:

[0030] (1) Drug preparation: dissolving insect sex pheromone (4S,6S,7S)-7-hydroxy-4,6-dimethyl-3-nonanone in ethylene glycol at a mass ratio of 10:1000 , to obtain the insect pheromone solution; then according to the ratio of insect pheromone and inert powder mass ratio of 1:2000, the insect pheromone solution is atomized and sprayed on the inert powder, stirred, dried, pulverized, and passed through a 300-mesh sieve Then get the insecticide powder;

[0031] (2) Spray insecticide: Use a duster to spray the above-mentioned insecticide powder. Before starting the powder spraying, all the doors and windows of the warehouse must be closed to avoid the loss of the agent; the unit spraying amount of Tobacco A is 0.5g / m 2 , the unit application rate of tobacco powder borer is 0.3g / m 2 .

[0032] Others are with embodiment 1.

Embodiment 3

[0034] The difference with embodiment 1 is:

[0035] A control method for tobacco pests, comprising the following steps:

[0036](1) Drug preparation: mix the insect sex pheromone 4,6-dimethyl-nonane-3,7-dione and 4,6-dimethyl-nonane-3,7-diol Dissolve in a mixed solvent of ethylene glycol and ethyl acetate at a ratio of 20:1000 to obtain an insect sex pheromone solution; then, according to the mass ratio of insect sex pheromone and inert powder as 1:3000, the insect sex pheromone The solution is atomized and sprayed onto the inert powder, stirred, dried, pulverized, and passed through a 400-mesh sieve to obtain an insecticidal powder;

[0037] (2) Spray insecticide: Use a duster to spray the above-mentioned insecticide powder. Before starting the powder spraying, all the doors and windows of the warehouse must be closed to avoid the loss of the agent; among them, the unit application rate of Tobacco A is 1.5g / m 2 , the unit application rate of tobacco powder borer is 1g / m 2...

Abstract

The invention provides pesticide powder, a preparation method and a control method of tobacco pests. The pesticide powder is prepared from insect sex pheromone, inert dust and solvent. The mass ratio of insect sex pheromone to inert dust is 1:(1000-5000). The invention further provides the preparation method of the pesticide powder and the control method of tobacco pests. By means of the pesticide powder, the preparation method and the control method, the pest killing rate can be greatly increased, adult male pests can not find female pests for coupling in a directed mode, and the population density of pests is controlled within the economic threshold range.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to an insecticidal powder, a preparation method and a method for preventing and controlling tobacco pests. Background technique [0002] Tobacco pests belong to the Coleoptera Elephidae family, which originated in the Americas and are worldwide pests of stored goods. They are distributed in all provinces (regions) except Ningxia and Qinghai in China. Tobacco pests have a wide range of harm, and can harm tobacco, tea, cereals, beans, dried dates, oilseeds, animal and plant specimens, leather, rattan and bamboo products during storage. The worm likes to eat the tobacco leaves that are aging, and is one of the most serious pests during the storage of tobacco. It can enter the interior of the cigarette with the processed tobacco, eat the tobacco, eat through the cigarette paper, and overflow the surface of the cigarette holder and the paper. , seriously affecting the availability ...
