Edible Bean School: Weed control strategies for top yields

When it comes to weed control, getting it right is key for edible bean success.

University of Guelph research shows, on average, weed interference can cause yield losses up to 56 per cent compared to 50 per cent in corn and 36 per cent in soybeans. When comparing edible beans and soybeans, U of G weed scientist Dr. Peter Sikkema notes that edible beans emerge just as quickly as soybeans, but they do not grow as rapidly or close the canopy as fast as soybeans, leaving them more sensitive to weed interference and greater yield losses.

On this episode of the RealAgriculture Edible Bean School, host Bernard Tobin and his guests focus on weed control strategies growers can take to the field for the 2021 season. Sikkema offers tips for growers in Ontario, while Manitoba Agriculture weed specialist Kim Brown-Livingston discusses how weed control strategies can differ in Western Canada and why.

Sikkema kicks off the episode by pointing out how market classes can impact weed control strategy and how products and rates have to be adjusted when growers are managing different classes — Adzuki versus white versus cranberry, for example. He also discusses the importance of weed control timing and rate and why he feels a two-pass weed control system offers the best value for growers.

Brown-Livingston notes that western growers do not have the range of weed control products available to Ontario growers, but they continue to do a good job with their weed control. She emphasizes the need for growers to start clean and stay clean and also reviews weed control considerations growers need to be aware of as many head into very dry planting conditions this spring.
