Presented by Breanne Tidemann, Agriculture and Agri-Food Canada, Lacombe, Alta., at the Herbicide Resistance Summit, Feb 27-28, Saskatoon.In order for harvest weed seed control (HWSC) to be effective, weed seeds still have to be retained on the plant at the time of harvest. If they’ve already dropped to the soil,…
Implementing a winter canola-soybean double crop can be a potential way to overcome challenges in soybean and canola production in Ontario, according to OMAFRA's latest CropTalk newsletter.Eric Page, research scientist in weed ecology, and Sydney Meloche, weed science technician, at AAFC Harrow Research and Development Center have conducted planting trials…
Early weed control has many benefits as weeds compete with crops for nutrients, water, and light. “Research on weeds germinating before the crop emerges as compared to crop emerging before the weeds shows a very significant drop in yield loss when the crop emerges prior to the weeds,” says Harry…
Herbicides have become very important for weed control. However, frequent and repeated use of the same herbicide groups has gradually resulted in development of herbicide-resistant weeds to the point that resistance has become a very serious problem for many Prairie farmers. When herbicide resistance is a relatively minor problem, growers…
Weed control is one of the main challenges for flax growers, and is even more challenging under organic production systems. Because flax is a poor competitor with weeds, yield losses can be significant when weeds are present. Cultural and mechanical control options can be effective techniques for weed suppression and…
Grows more than two inches per day. Produces over one million seeds per plant. Grows 10 feet tall. Resistant to at least four different herbicide groups in the U.S. No wonder 200 American weed scientists in 2017 ranked Palmer amaranth the most troublesome weed in broadleaf crops, fruits and vegetables.
Over the past several years, Neil Harker, research scientist with Agriculture and Agri-Food Canada (AAFC) in Lacombe, Alta., has been investigating integrated weed management systems (IWM), with a focus on wild oat management and control. An early study, Test 42, compared ways of managing wild oat using crop rotation (barley-canola-barley-peas…
Dr. Peter Sikkema and Dr. Darren Robinson, weed scientists at the University of Guelph, will be hosting an intensive course on herbicide activity (mode-of-action, selectivity, efficacy, crop injury) and weed identification in London, Ont., this coming fall.
