Pre-harvest herbicide applications help maximize harvest windows while improving crop quality and eliminating problem weeds. Ensuring a product's mode of action matches the time of application is critical, but sometimes, whether due to logistical challenges or adverse environmental conditions, the timing of pre-harvest herbicide applications can vary significantly. According to Tristan Huber, Grow Team Advisor with Co-op, flexibility in herbicide options is key to giving growers opportunities for earlier, middle and late application periods. Now, with a new forthcoming product, HOT AQT!, Co-op has options for all three. Why apply pre-harvest herbicides? Weeds at harvest can reduce harvest efficiency and FLEXIBILITY IN PRE-HARVEST NS WEED CONTROL compromise crop quality due to contamination and dockage. Pre-harvest applications help manage these risks and promote a more uniform crop dry-down for timely and efficient harvest. Having fewer living weeds late in the year also suppresses weed seed banks and reduces the chance that harvest equipment will become plugged while in operation Huber said it's important to know what the goal of pre-harvest application is - whether it's for weed control or crop dry-down - because pre-harvest glyphosate and desiccating applications are different in how they behave. “Two big reasons for pre-harvest application are controlling weeds so you don't get viable seeds into that seed bank, and no green material for harvest," said Huber. “Timing is important. If you wait too long, you may not get your money's worth on the application since the crop is maturing on its own, and weeds have already set seeds. If your application is too early, you might have some grain quality impacts with green or shrunken seeds that weren't fully matured. If you execute a good in-crop herbicide application, and time pre-harvest glyphosate applications right, you can usually tell what fields have been sprayed properly the next spring they just seem that much cleaner." What to use when Historically, Co-op has offered two products for pre- harvest desiccation: VECTOR®, a systemic glyphosate formulation that has a wider application window than Diquat, and BOLSTER® Il, a more rapid-acting Diquat dry-down product for later applications
