Knowledge, skill and being prepared to go the extra mile are what separate an average sportsman from a great one. The same holds true when herbicide-resistant weeds are in season. Dow AgroSciences recommends the following best management practices to minimize the risk of herbicide-resistant weeds developing on your farm:

Choose Your Weapon Herbicide resistance is a science. Weeds can be an easy

prey to underestimate; don’t let them sneak up on you.

• Rotate herbicides with different or multiple effective modes of action. Be sure you’re rotating herbicide groups, not just brand names • Rotate herbicide-tolerant traits and/or use herbicide-tolerant trait stacks • Consider a pre-emergence application of a residual herbicide • Set-up a rotation tracker to record crops and herbicides used in each field • Avoid a chemfallow system that relies solely on glyphosate. Try adding a residual herbicide to a burndown application to help provide better weed control throughout the fallow period • Try a fall burndown program to help control volunteer crops and winter annual weeds

Know Your Territory A seasoned hunter masters their terrain and is always a step

ahead of their game. Don’t let weeds know your fields, and your rotations, better than you do. • Don’t make your crops compete for survival. Control weeds with clean tilled fields or a burndown herbicide program prior to planting • Be sure to follow all herbicide label instructions, including correct timing, spray volumes and recommended full labeled rates • Rotate crops as much as possible (canola, fallow, soybeans, sorghum or sunflowers may be good options) • Plant certified, clean or otherwise weed-free seed and ensure all equipment is properly cleaned between fields • Use tillage and/or non-selective herbicide applications to control weed escapes post-harvest

Hunt to Kill Every good hunter knows the importance of scouting prior to opening day. These are your fields, and protecting them is your livelihood.

• Scout your fields for weeds before and after spraying • Treat every weed escape/surviving weed as if it is resistant • Know your weeds to guarantee you’re selecting the proper control methods • Do not allow mature weeds to seed; remove them with post-harvest tillage, hand removal or spot herbicide applications • Contact a local retailer, crop protection company or extension service for help with weed identification or to test your specific resistance issue

Weed resistance management practices will not be identical for every grower or in every field. It is important to use multiple practices to manage or delay resistance. Don’t be afraid to try new strategies—keeping in mind that no single approach will be completely effective on its own. Herbicide resistance is created over many years, so preventing it must be an on-going and dedicated management practice by everyone involved.
