How good is your weed identification? If you had to answer if a weed was a “late flushing” weed or a winter annual, could you answer? While no weed specialist expects every farmer to be a weed expert, knowing a few specific details about your enemy is actually quite helpful in the war on resistance.
What’s more, when you add your weed biology understanding to your crop management strategy you end up with a full arsenal for the fight ahead — integrated weed management. IWM is a big, long title that can seem really overwhelming, but it doesn’t have to be. As Mike Cowbrough, weed specialist with the Ontario Ministry of Agriculture, Food and Rural Affairs, discusses with Bernard Tobin in this fourth episode of When Weeds Won’t Die, understanding the life cycle of problem weeds means that you can nip the spread of weeds in the bud…sometimes literally.
From why crop rotation is such a key part of weed control and resistance management, to the one season you may be overlooking as a key time for weed control, and on to controlling the weed seed bank and seed set, Cowbrough runs through six steps critical to integrated weed management and the war on herbicide resistant weeds.
