Weed control in dry beans can be a daunting task. Management decisions should be based on knowledge of weed pressure and weed species on a field specific basis. There is no one size fits all scenario with weed control in dry beans. The size of farm operations means there is a diverse mix of past…Continue readingPermit and grass herbicide tankmix partner comparison in white bean
By: Meghan Moran, Mike Cowbrough (OMAFRA) and Dr. Darren Robinson (University of Guelph-Ridgetown Campus) Group 27 herbicides, commonly referred to as “bleaching” herbicides inhibit an enzyme called HPPD (p-hydroxyphenyl pyruvate dioxygenase). Several herbicides containing Group 27 active ingredients are used pre-emergence or early post-emergence in corn. Dry beans are often grown after corn in rotation…Continue reading“Bleaching” Herbicide Carryover Injury in Dry Beans
AgTiv is a biological product (Premier Tech Agriculture, Quebec, Canada) that contains mycorrhizae (Glomus intraradices) spores. The product Myconate (Plant Health Care, Raleigh NC) contains the isoflavone formononetin. Both products have a powder formulation applied as a seed treatment, and a liquid formulation applied with a liquid fertilizer at planting. Product claims include increased plant…Continue readingMycorrhizae Products for Beans 2016-2017
Postemergence applications of Permit provide excellent control, reducing volunteer soybean plant density, plant biomass, dockage and protects yield of white beans.Continue readingVolunteer soybean control with Permit applied post-emergence in white beans
Overview Reglone is a true desiccant, used to rapidly dry down plants prior to harvest. Any green plant material contacted by Reglone will be killed. It is rapidly absorbed by foliage but has limited translocation through plants; it is a contact herbicide. There are several generic products sold in Ontario that are equivalent to Reglone.…Continue readingReglone (diquat) and Pre-Harvest Applications
Acres are limited, but dry beans are successfully grown in no-till systems in Ontario. Dry beans respond to some form of tillage in the seed zone at planting. This is largely because of their inherently small and poorly developed root system. Tillage coulters on the planting unit will provide the necessary seed-zone tillage to optimize emergence,…Continue readingNo-Till

Strip Till
Strip till systems are becoming increasingly common in Ontario dry bean production. Strip till offers the advantage of some tillage in the seed row while reducing the overall amount of tillage and leaving some residue on the soil surface. The strip tiller can be run in the fall or in the spring; some producers conduct…Continue readingStrip Till

ATS as a Herbicide Carrier
Ontario producers who want to apply sulphur in dry beans have considered using ammonium thiosulphate (ATS) as a herbicide carrier. Jar tests are a good way to evaluate mixes before putting them in the spray tank. A jar was test conducted with ATS and Dual II Magnum. In the photo below, the jar on the…Continue readingATS as a Herbicide Carrier
Introduction Azuki beans have been grown in Ontario for over two decades with an estimated 20,000 acres being grown in 2020. Acreage has continued to climb as the profitability of growing azuki beans is very attractive to growers. A better understanding of agronomic practices to produce azuki beans has spurred on growth in this niche…Continue readingVolunteer azuki bean control with Permit herbicide applied post-emergence in white beans
Although dry edible beans are legumes, they do not obtain their full nitrogen requirement through nitrogen fixation. Studies have not shown a yield benefit to inoculation with rhizobia. Ontario nitrogen research has demonstrated yield increases in some years but has not shown an economic response to pre-plant incorporated or banded nitrogen. Nitrogen applied pre-flower does…Continue readingNitrogen
