Background
In the process of grain storage, pests are introduced in many links to damage the stored grains and bring economic loss to the grain storage. When the granary is emptied after the previous grain delivery, residual pests can be left and become sources of the pests, which are harmful to the subsequently stored grains. Therefore, the adoption of various pest control methods to kill the possible pests in the empty granary is an important aspect for ensuring the safe storage of the grains.
The hot fogging method is to make a hot fogging agent with an insecticidal effect generate high-speed airflow through a jet engine, atomize the agent by utilizing the venturi principle, and form fog drops (hot aerosol) with the diameter of 1-10 microns. The insecticide has good penetrability, can effectively exert the insecticide on places which are difficult to be reached by common treatment methods such as grain bin seam wedges and the like, thereby improving the insecticidal effect, and is commonly used in places such as forests, orchards, protected areas, underground water channels and the like.
However, the use of the hot fogging method in an empty granary is still less at present because no special insecticidal hot fogging agent formula exists. When forestry and sanitary insect control are carried out, the general hot fogging concentrate formula is prepared by using petroleum processing fractions as solvents to form the hot fogging concentrate, and after the hot fogging concentrate is used, large smell can be remained in a granary, so that bad influences such as peculiar smell and the like which influence sensory quality are easily caused on subsequently stored grains. Therefore, the hot fogging concentrate of the prior art has a problem that the smell is likely to remain.
