Biocontrol thriving in Canadian floriculture greenhouses:There's been growth in both the number of biocontrol users and the extent of biocontrol use.

摘要

It has been four years since we last surveyed floriculture growers, and in that time, there have been some big changes in the way Canadian growers are using biocontrol. Our most recent survey, conducted over the spring and summer of 2018, received responses from 47 ornamental greenhouse growers. Primarily from Ontario, operations ranged from less than 5,000 m2 to 100,000 m2. Respondents represent approximately 24 per cent of the ornamental greenhouse acreage in the province. We received responses from wholesale, retail and propagation growers, who produce a total of 43 different kinds of primary crops.
