Comparing Biocontrol to Pesticides for Bemisia Whitefly Control in Poinsettia

P1020349

T’is poinsettia sticking season once again, and the question always comes down to the same thing: do I use chemicals to control Bemisia whitefly and hope it works this year? Or do I switch to biological control?  Here we show some head to head comparisons that can help you decide.

An in-depth discussion of this topic was also captured by MSU’s “Bug Bites” last year, and I’ve included the video below.

Now that poinsettias are safely tucked into their prop trays and the threat of Erwinia (Pectobacterium) is almost over, it’s time to think about other poinsettia issues.

Root rots, nutritional issues, environmental stress and PGR mistakes can all be costly in this high-value crop.

Read on for common pitfalls and how to avoid them, and for some great video resources on poinsettia production.

Poinsettia Problems: Your Monthly Scouting Guide, 2021

This post on poinsettia problems was contributed to by Drs. Chevonne Dayboll and Sarah Jandricic.

When poinsettias get problems,  they always seem to hit hard and fast. Things like whitefly, Lewis mite, root rots, and nutritional issues can all quickly derail a quality crop. This is why scouting might be more important in this crop than any other.

Here’s a month by month guide on what you should be looking for to prevent small problems from becoming big issues.

They’re HEEERRE! Japanese Beetles Are In Flight.

Japanese Beetles Have Started To Emerge

Posted on June 25, 2021 by Jen Llewellyn

Japanese Beetle (Popillia japonica) adults are starting to take flight in southern Ontario!  They have been spotted in Hamilton and Toronto this week.

Look for these shiny green and copper beetles feeding on grape leaves, roses and many other trees and shrubs. Where possible, homeowners can knock adults into a bucket of soapy water (to smother them).  Several insecticides are registered for the adults in greenhouses and nurseries, including BeetleGONE.

European chafer (Amphimallon majale) adults are also starting to emerge. Look for medium brown scarab beetle swarming blooming Linden trees (e.g. Tilia cordata).  Historically we see them around Canada day in the Guelph area.

And don’t forget about our little friends, the Rose Chafers (Macrodactylus subspinosus), pictured aboveThey are also out in full force. These scarab beetles feed on the flowers, fruit and foliage of several ornamentals.  The larval stage feeds on roots of grasses and weeds (usually a sod nursery pest). Like most scarab beetles, females are more likely to lay their eggs in sandy soils and will avoid egg laying in clay soils.  Insecticides for the grub stage of other scarab beetles will also reduce larvae of rose chafer.

Preventative applications of Intercept and Acelepryn are registered for white grubs in nursery and greenhouse production and the application period begins now. (Above photo: European chafer larval feeding damage).

Reminder: Using Temporary Help Agencies and Employment Standards Webinar June 22

The first installment of OMAFRA and MLTSD’s monthly webinar series is scheduled for Tuesday, June 22, 12 – 1pm ET. These webinars will occur on the 3rd Tuesday of each month at noon.

Next week’s webinar is: Using Temporary Help Agencies and Employment Standards Webinar

When faced with a labour shortage, many employers in the agriculture sector turn to a temporary help agency (THA) for assistance. But did you know clients of agencies have legal obligations when using a THA? Before speaking with an agency, clients of agencies should find out what their responsibilities are under the ESA.

However, the cooler spring means pupation may take longer. So what does that mean for timing of control products?

This post answers those questions and provides current infographics for JB control for those exporting to non-JB areas.
