Know which looper species this is? Are you SURE? If not, keep reading, as some species could get your shipments detained at the border. Photo: Steve Hatch, Bugwood.org.
With spring crops behind us and summer approaching, most of you are probably concentrating on the Big 3: thrips, aphids and whitefly. But recent alerts put out by the United States Department of Agriculture (USDA), bring a new emphasis to caterpillar control. Read on to understand what’s happening, how to control occasional pests like cabbage looper, and avoid potential issues at the border.
Botrytis spots on Primula petals.
With the intense period of rain we just had, and with MORE rain coming on Friday, it’s time to think about Botrytis control and prevention. One of the most common and destructive diseases of greenhouse crops, outbreaks usually follow periods of cool, damp, cloudy weather. Unfortunately, I can’t order up more sun for you, but I CAN suggest some management tactics.

Spring is here, and we know you’re busy! Here’s a quick but very important refresher on fertilizer injector maintenance. Ensure they’re working properly on a regular basis to avoid extra headaches.
How do I know if my injector is working properly?
Hopefully damage to foliage wasn’t your first sign things were a little off! Some things to remember:
- The dilution ratio needed for each application should be known and adjusted as needed.
- Remember that tracing dye in water-soluble fertilizers should never be used as an indicator of the actual strength of a fertilizer mixture.
- If you are using multiple products or chemistries ensure they are compatible for tank mixing before running them through the injector.
- If deviations greater than 5% from the expected setting occur, contact an irrigation specialist for assistance or repair. (But first, double check that math!)
Fertilizer injectors come in all shapes and sizes in the greenhouse.
There are two common methods to check if your injector is working as expected. Regular calibration is needed to ensure that an injector is operating properly. You should complete both methods listed here to ensure accuracy. Continue reading
Do you have a strategy to help mitigate pests coming into your facility, like dipping cuttings upon receipt?
The CFIA has recently released the Floriculture Sector Biosecurity Guide. Despite it’s imposing name, this is an excellent “road map” to help protect your facility from unwanted pests. The Guide offers biosecurity strategies from the time plants come in the front door ’till they’re out in the compost bin.
Don’t have a facility-wide Pest Management Program in place? This guide can provide the framework. (Why start from scratch?). Already have a strategy to mitigate risks from pests at your farm? Compare YOUR plan with the Floriculture Guide to see if you’ve overlooked anything.
