Mealybugs, which have long plagued tropical plants, are now appearing in a wider variety of crops, from chrysanthemums to poinsettia. On Wednesday, February 11th, please join Dr. Raymond Cloyd of Kansas State University, for an hour-long exploration of mealybugs and their management.

As several greenhouses (both vegetable and ornamental) have undergone random inspections in 2025, it’s good to be aware of this federal program, and what an inspection could look like.
In this hour long session, Ryan Munroe of NVK Nurseries will share practical tips for monitoring plant health and explain how media properties can influence irrigation, pH, and rooting.

Welcome to the Vineland DLI report for December, 2025!
In December, Vineland received 33% less light than in November, 2025.
Read on for the detailed data report and more information about our DLI data collection project.
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.
Continue reading “In Case You Missed It: Two-Spot Cotton Leafhopper – a New Pest of Hibiscus.”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.
