like this on the conventional side as herbicide resistance continues to develop." HUNTING WEEDS Nurse and three other AAFC scientists across Canada are also studying abrasive or projectile in-crop weed control in dry beans, potatoes, grapes, and blueberries. Each researcher has a commercial sandblaster attached to an air compressor that can shoot corn grit, walnut shells, and a mix of both materials, in various sizes, at a rate of 480 kg per hectare. Coined 'weed hunting,' this method will be evaluated over the next two years in small plots where some fields will be treated with only projectile materials and others will be treated with a combination of projectiles and herbicides. "It's all about the right timing," explains Nurse, who is leading the dry bean component of the study. "We plan to shoot weeds at the same time that farmers might use a herbicide, so it fits into their regular schedule. It also lines up with when the weeds are just emerging from the soil and are most susceptible. They can absorb damage from the projectiles better when they get older." By 2024, the researchers aim to find the best projectile material and determine the ideal size and application rate for weed control of more than 80 per cent without significant yield loss or crop injury. Nurse believes abrasives could be another solution for farmers battling resistance or wanting to reduce herbicide use. l ONTARIO GRAIN FARMER 27 NOVEMBER 2022 "We found that if we apply it at the same time as we would normally apply herbicide, we get a very similar burndown, and it also provides equivalent fall weed control."
