“…Envirosol products such as Permigas, Pestigas and Insectigas are commercially available for the control of insect pests in domestic, commercial and industrial buildings. For the export cut flower and asparagus industries, Floragas and Hortigas were developed as postharvest fumigants (Carpenter 1987;Carpenter and Stocker 1992). Phosphine, a fumigant for stored grain, is being developed by BOC Gases Australia (Karunaratne et al 1997;R.…”

Envirosol technology, which uses carbon dioxide to deliver pesticides as aerosol droplets into enclosed spaces, is being developed to deliver fungicides into greenhouses. Three experimental aerosol formulations for the control of powdery mildew in cucumbers, and grey mould in tomatoes, were evaluated in two separate trials. The high pressure aerosol formulations were sprayed into the greenhouse through an automated application system with spray nozzles strategically placed in the greenhouse. Severity of powdery mildew in cucumbers was reduced by 65%, and incidence of grey mould on tomatoes was reduced by 68% when treated with these formulations.
