IPM in Mandevilla: Part 3 – Reducing Costs in Early Production.

Over the past few months, I’ve posted a series on IPM in Mandevilla – now one of our more challenging crops, thanks to Thrips parvispinus!

This week I’ll be going over strategies we’ve used at a few farms to decrease costs of IPM in Mandevilla NOW, in early production, which can creep up under weekly spray programs. I’ll also be incorporating some case studies from growers, to better illustrate what’s working in the real world.

I’ve included an updated chart for IPM of Mandevilla pests in this post that is a bit cleaner. Lastly, stay tuned for Part 4, which will cover how to save money in late production.

How To Manage Parvispinus, Oleander Aphid and Spider Mites Effectively in Mandevilla: Part 1 – Propagation.

When Thrips parvispinus first came on the scene in Ontario, our one goal was to knock back this pest any way we could. Four years later, we are suffering the effects of an all-chemical program. This includes high costs, along with insecticide resistance developing in two-spotted spider mite, which used to be managed biologically before Parvipsinus came along.

Based on OMAFA’s work with commercial farms, along with input from technical reps from biocontrol companies, we’ve come up with a more refined IPM program for Mandevilla that balances Parvispinus control while taking into consideration other pests, as well as costs.

I’ll be going over this program in detail over a 3 part series, so buckle up!
