How to use aerosols in greenhouses

Finally, the aerosols at the greenhouse outlet were all lit and the people left the site to seal the greenhouse overnight. The next morning, all the vents in the greenhouse were opened, and sufficient ventilation allowed people to enter the shed.

Fourth, use the dose. According to the size of the greenhouse space, the occurrence of pests and diseases and the effective content of aerosol agents.
