While attending the OFA meetings in Ohio in July 2013, I had the opportunity to hear three greenhouses growers talk about how they are adopting biological control at their operations. It was rather refreshing since we have been trying to get greenhouse growers to adopt more biological control since the mid 1990s. The cost of chemicals has skyrocketed, pest resistance is becoming more troublesome, and the restrictions have made chemical applications less attractive to many growers. I am relaying the successes of these greenhouse operations and biological control use by Maryland operations so more growers will begin to consider a biological approach to help control insects and diseases in greenhouses.
