The Science For Success team put several commercial seed treatments to the test across a variety of field conditions to see how they perform in the real world. Check out the results in our new Whiteboard Series video! ow.ly/oBWr50VQ7pI

"Given the uniformity of the response across these 46 sites, there is no evidence that foliar fertilizers increase soybean yield in the absence of visual symptoms of nutrient deficiency.” Insights regarding these trial sites can be found here: resources.ipmcenters.org/view/resource.…

Alfalfa: scouting for potato leafhoppers and weevils. Good news, not finding any - only catching 🐌 snails and slugs in the sweep net to date.

Alfalfa Update (East ON):First potato leafhoppers caught this past week—~0.4 per sweep in 14" high 2nd cut alfalfa, well below threshold … for now. With this heat, populations can double in a week or less. New seedings are most at risk. More info: tinyurl.com/mrjr7a3x

Soybean aphids are showing up at detection levels across much of Eastern Ontario, currently on the newest trifoliates. The presence of ants or lady beetles on plants can be a sign of aphid activity.

Alfalfa Leafhopper Update (East ON): Populations have jumped—1+ per sweep in new seedings and second cut. Hopper burn appearing. Harvesting in the next week should knock them back. Then, be sure to scout regrowth 5–7 days after harvest to assess hopper pressure. #ONalfalfa #IPM

Leafhopper scouting just got easier — one jumped through the car window as I drove by an alfalfa field. My type of scouting!

Soybeans in 30" rows: Canopy closure at Winchester Research Station—May 5 beans at 58% vs May 28 at 32% (Canopeo). Even early planting misses a lot of sunlight during the longest days. Dry spring (½ normal May–June rainfall) not helping either. Pics tell the story. #OntAg

Soybean aphid populations are building across much of Eastern ON but remain low—typically 1–20 aphids on the top trifoliate of every few plants. A few fields had higher numbers in small pockets, likely from early local overwintering populations.

Soybeans & nitrogen? Multi-year Illinois trials show small, inconsistent yield bumps from N. “… yield responses to N decreased as the untreated control yield increased (Figure 1) …”. Details here: tinyurl.com/2s49t39t . Similar story in recent ON trials. #OnAg

A bit of a scorcher in Eastern Ontario today. Even the squirrels have gone full stretch mode in the shade and calling it a day!

Western Bean Cutworm update: First moths caught in pheromone trap at Winchester Research Station, putting peak flight around August 7. If an insecticide is needed, the spray window is typically 4–7 days after peak to target larvae before they enter the ear. #OntAg

Soybean Aphid Update – Eastern Ontario: Populations have more than doubled in the past 5 days and are still rising. Aphid levels vary widely—many fields are seeing 25–150 aphids/plant, but a few fields have already hit control thresholds. #Soybeans #OntAg

Western Bean Cutworm update:Trap counts at Winchester remain low. Based on previous years, peak flight is expected around Aug 7–10. Since WBC prefers pre- to early-tassel corn for egg-laying, later-planted fields are at greatest risk this year.

True Armyworm Update – Eastern Ontario: Not quite an alert, but a good time to check fields. Localized feeding reported in Dundas & Renfrew (Paul Sullivan). Mike Hunter notes significant outbreaks in Jefferson & Lewis counties, NY. More info: rb.gy/yp175s

Soybean Aphid Update – Eastern Ontario: Populations continue to vary widely and are starting their disappearing act. Aphids are moving from the top trifoliate into the lower canopy, and dwarf forms are showing up—both making accurate counts more challenging.
