DLI Data – December, 2025
Not Familiar with AFE’s Grow Pro Webinar Series? You Really Should Be!
While chatting with various growers and IPM technical reps this year, I realized some in Ontario aren’t familiar with the American Floral Endowment’s (AFE) Grow Pro Webinar Series. This is an excellent series that shares floriculture research funded by AFE, as well as other topics.
Previous webinars have focused on things like thrips and botrytis control, biostimulants, growing in reduced-peat substrates, and more.
A webinar I’ll recommend for January is one on oomycete pathogens, like Pythium and Phytophthora:
| Ruh Roh, Root Rot! Managing Oomycete Pathogens in Floriculture Production Speaker: Dr. Johanna Del Castillo, UC Davis Tuesday, January 20th at 1PM EST Oomycete pathogens remain a persistent threat in floriculture production, causing significant losses when conditions tip in their favor. In this webinar, Dr. Del Castillo will dive into the biology of Pythium and Phytophthora, how to diagnose root rot issues, and the most effective management approaches. Attendees will gain actionable strategies to improve root-zone health and reduce disease pressure in their operations. When you’re thinking “ruh roh,” it’s already too late—join us to get ahead of root rot and outsmart oomycete pathogens. |

Just when we think we have Thrips parvispinus under control, a new pest is threatening tropical ornamentals. The two-spot cotton leafhopper (Amrasca biguttula) is mainly a pest of – you guessed it, COTTON – but also attacks hibiscus. Growers in Ontario should be aware of this pest if importing hibiscus cuttings from the Southern U.S., where this pest has currently invaded.
There’s been lots of good information shared on this pest recently. Read on for a summary relevant to ornamental growers, including what to look for, effective pesticides and what actions you should take NOW.

GrowON Webinar, December 17: Worms at War – Maximizing Nematode Efficacy for Greenhouse and Nursery Crops.
As December winds down, thoughts are now turning to spring crops. This can include spring bedding crops or nursery plants coming out of their winter sleep. Both of these can bring onslaughts of pests like thrips, fungus gnats, shore flies and even weevils. Nematodes are an important natural enemy in fighting these pests, and are often the gateway into using more biocontrol. But are you using them to the best of their abilities?
Please join Greg Bryant , Technical Lead at Beneficial Insectary, for an hour-long exploration of what nematodes can do, if you treat them right.

We’ve recently mounted at daily light integral (DLI) meter at the Vineland Research and Innovation Center! As a result, the OnFloriculture blog will be making regular monthly posts detailing monthly DLI data for Vineland, Ontario.
This meter acts as a reliable record of light levels for Vineland and surrounding areas, giving growers and researchers easy access to data that may help explain crop outcomes. The information is neatly organized, allowing for quick month-to-month comparisons and a clearer understanding of light conditions throughout the growing seasons.
