Webinar this THURDAY: Making the Most of Spraying in Covered Crops (including Cannabis)

As anyone growing greenhouse vegetables, floriculture or cannabis crops knows, most pesticide application information out there is NOT geared towards covered crops. To help growers improve spray coverage and product efficacy of both conventional and microbial pesticides, Niagara College’s Cannabis Program has put together a webinar of experts. Together, they have over 100 years of combined pesticide application experience (*insert joke about how old they all are here*).

The panel includes both government and industry experts, including Dr. Jason Deveau from OMAFRA, Dr. Michael Brownbridge from BioWorks, and Louis Damm from the Dram Corporation. This webinar will focus on cannabis as a model crop, but much this information is highly applicable to floriculture as well.
