Yield losses typically reach around 55% when weeds are not properly managed in edible beans. To minimize any yield losses from weed competition in edible beans they should be kept weed free from emergence to first flower. Research by the University of Guelph (Ridgetown campus) has demonstrated that weed control is maximized in edible beans when a…Continue readingBasic Principles of Weed Control for Dry Beans

Group 15 (Dual, Frontier) Injury
Group 15 active ingredients commonly used for weed control in Ontario dry beans include S-metolachlor (Dual II Magnum) and dimethenamid-P (Frontier Max). Occasionally these products cause injury; injury is influenced by herbicide application rate and timing, soil crusting, seeding depth, weather conditions, and market class. Symptoms Herbicide is primarily absorbed through the elongating epicotyl/hypocotyl. Plants…Continue readingGroup 15 (Dual, Frontier) Injury
Currently, 2,4-D ester is not registered for pre-plant or pre-emergence application in dry bean. The results from this study found that at the proper application timing 2,4-D ester can be used safely in dry bean for the control of glyphosate-resistant Canada fleabane. Recommended timing is 14 days pre-plant at the current soybean label rate of 320 ml/ac.Continue readingPre-plant and Pre-emergence use of 2,4-D ester in Dry Bean
Introduction Determining the best weed control program for white bean producers can be challenging. Weed pressure, weed species composition, herbicide application timing, application rate and, of course, cost are all factors to consider. There are a number of products available to growers that provide differing levels of control across a range of weed species. Background…Continue readingPermit and Treflan Tank-mix Evaluation in White Bean
