VIDEO: Deciding when to spray to wipe out weeds

Know your economic threshold before firing up the sprayer

Deciding when to spray is key to limiting the spread of weeds and capturing the best yield your crop can offer. As with nearly every aspect of crop production, weather plays a key role and the amount of precipitation in a growing season  – and the timing of your herbicide application – will go a long way in determining if it pays off.

At Crop Diagnostic School in Carman in July, Tammy Jones, weed specialist with Manitoba Agriculture, discussed the economic thresholds of weed control – offering examples such as redroot pigweed and volunteer canola in soybeans and how they impact yield loss – what factors to consider before deciding to spray, and some characteristics you should look for when trying to identify weeds.
