This preventive technique improves efficacy of BOTH biocontrol and pesticide programs for Bemisia, since it lowers your starting pest pressure.
If you’re still unsure of how or when to apply cutting dips, check out the rest of this post.

Here in Canada, we’ve been talking for years about research on the highly effective method of dipping your poinsettia cuttings in low-risk pesticides to reduce starting whitefly populations.
Thanks to Dr. Rose Buitenhuis (VRIC), Cary Gates (FCO) and BioWorks, the label for BotaniGard WP has now officially been expanded to include dip applications. This now adds to our arsenal (see below for more dip products).
Read on for the current BotaniGard label and how dipping can help improve your Bemisia whitefly program this year, whether you’re using pesticides or biocontrol.

In 2017, I had an interaction with a grower where their long-standing biocontrol program for thrips suddenly seemed to be failing. After a (too long) investigation by myself, the grower, and consultants, we found out the horrible truth: their predatory mites were being MURDERED (Duh dun DUHNNN!)… By improper storage.
This post focuses on all the ways YOU might also be guilty of mite murder, and how to make sure your mites are still alive and kicking in those little sachets.
Ever needed just to quickly look up a rate for a particular pesticide, or see if it’s compatible with your bio program, only to get lost on Google or get frustrated by the numerous tables in Pub 370? Well, me too.
Read on for resources to make accessing pesticide information quicker and easier for Ontario’s floriculture sector.
These include a new mobile app for ALL registered pesticides, as well as a downloadable spreadsheet you can tailor to your needs.

NOTE: This is a re-post because it now comes with an awesome new video of how to monitor you mite sachets!
Recently, I had an interaction with a grower where their long-standing biocontrol program for thrips suddenly seemed to be failing. After a (too long) investigation by myself, the grower, and several consultants, we found out the horrible truth: their predatory mite were being MURDERED (Duh dun DUHNNN!)… By improper storage.
This post focuses on whether YOU might also be guilty of mite murder. (And yes, I’ve stooped to the level of click-bait titles).
Special thanks to Graeme Murphy (BioLogical Consulting) Dave Neal (Koppert), Rose Buitenhuis (Vineland Research and Innovation Centre) and especially Ronald Valentin (BioWorks) for all their knowledge that went into this post!
