Getting ^ring Crop Off to a GoodStart

摘要

Overall, 2017 was a pretty good year for Ontario's spring flower crops in terms of pests. Insects like western flower thrips were fairly low (no heavy fly-ins like in 2016) and more severe diseases were scarce. Here are some tips for how we can keep 2018 going in the same direction.Start Clean - and Keep it Clean: Unlike 2016, we hardly saw any black root rot (Thiekviopsis), even in highly susceptible crops like calibrachoa last year. Part of this might be attributable to greater awareness of this disease. Growers who had dealt with this before adopted more stringent sanitation practices, and applied prophylactic fungicide drenches. Going into 2018, Fusarium seems like it may be more of a problemthat could extend into the spring.
