Season Long Protection With Residuals
I know it may seem early to start thinking about herbicides for next year, but with harvestability fresh on your minds, now makes a great time to start planning. We know early and mid-season weed management is crucial in maximizing corn and soybean yields. Utilizing soil residuals in pre-emergent and-post emergent herbicides play a big part in the weed management solution.
Some growers had cleaner fields this year than they had in the past thanks to Liberty and Dicamba. These results are exciting but with the extra application restrictions, residuals become even more important. Both Dicamba and Liberty must be applied by R1 in soybeans and V6 in corn. On top of this, the EPA just recently announced that Dicamba can only be sprayed on soybeans within 45 days after planting. This gives weeds a lot of growing season to take hold and do some damage. This is where our residuals come into play.
Residual activity length and effectiveness from in-crop applications can vary depending on weed species, herbicide application rate, rainfall after application, weed density, tank mix partners, and crop canopy. This is why it is important to overlap residual modes of action for the best results.
Our recommended weed control strategy is to use three modes of action up front and follow up with at least two modes of action post. Having a weed control strategy in place now will help alleviate some in-season stress and set you up for cleaner fields all season long.
