An on-farm trial comparing different brands, types and colours of sticky traps done by OMAFA. This is a guest post written by Jessie deHaan (M.Sc.; Research Technician, Biological Crop Protection at Vineland Research and Innovation Centre). Now that it’s halfway through spring bedding plant season, you may be considering changing some of your current IPM or production practices for next year that just aren’t working as well as they could. Conducting on-farm trials is an easy way to evaluate how well a new product, process or technology will work in your operation. Before making any large-scale changes, it is important to test things on a small scale first . Read on to learn how you would go implementing a small on-farm trial to get you results that are meaningful. The Basics of On-Farm Trials Because this is a long post, we’ve put in this table of contents so you can quickly refer back to a section if you’re setting up your own trial in the future!

Last week, I posted an updated IPM plan for Mandevilla that balances Thrips parvispinus (“Parvi”) control while taking into consideration other pests , as well as costs . The last post covered propagation in detail , including biocontrols and chemicals. This week I’ll be going over the best way to balance control of Thrips parvispinus (“Parvi”) and two-spotted spider mite (TSSM) in production. I’ll provide a working Parvi spray program that gives you high-quality plants by sale, but also makes sure spider mites don’t walk away with your crop (or your wallet!).
