Fumigation insecticide, preparation method of fumigation insecticide and disinfection and killing method adopting fumigation insecticide

Abstract

The invention relates to a fumigating insecticide, a preparation method of the fumigating insecticide and a disinfection and killing method adopting the fumigating insecticide. The fumigating insecticide is prepared from the following components in parts by weight: aluminum phosphide, cyhalothrin, chlorantraniliprole, ethanol, polyethylene glycol, phenolic resin, guar gum, calcium alginate and castor oil polyether polyol. The preparation method of the fumigating insecticide comprises the following steps: mixing and stirring all the raw materials at the temperature of 55-65 DEG C, then rapidlycondensing, and drying at the temperature of 40-50 DEG C to obtain the fumigating insecticide. The disinfecting and killing method adopting the fumigating insecticide comprises the following steps: atthe temperature of 20-25 DEG C and the humidity of 30-33RH%, putting the fumigating insecticide into a closed space at the usage amount of 6-10g / m < 3 >; the fumigating insecticide has the effect ofstably and durably releasing hydrogen phosphide, so that the effect of durably preventing and killing insects can be achieved by using a relatively small amount of fumigating insecticide, and the costof the disinfecting and killing process is saved.

Description

technical field [0001] The present application relates to the technical field of pesticides, in particular to a fumigating pesticide, a preparation method thereof and a disinfecting method using the pesticide. Background technique [0002] Tobacco leaves, as raw materials for the tobacco industry, are generally stored in warehouses for a long time, and tobacco leaves generally contain basic nutrients needed for the growth of microorganisms and insects, such as glucose, protein, organic acids, chlorophyll, nicotine, etc. Therefore, tobacco leaves In the process of long-term storage in the warehouse, pests are more likely to occur. Tobacco leaves infested by pests will be mildewed, broken, perforated, and the yield of silk will decrease. In addition, insect eggs, insect excrement, insect corpses, etc. will also pollute the tobacco leaves, affecting the quality of the tobacco leaves, and more seriously will make the tobacco leaves unusable. value. Therefore, during the storag...

Problems solved by technology

[0004] In the process of insect control and insecticide in the warehouse, if the amount of aluminum phosphide is low, the concentration of phosphine produced by the decomposition of aluminum phosphide will be low, and the concentration of phosphine will decay quickly, so it cannot play the role of insecticide for a long time. Function; if the amount of aluminum phosphide is high, the cost of insect control and insecticide will increase, resulting in waste
