SC KS | Couple things...
1) I will agree that authority products last longer, even in our coarse textured soils. Now... the authority line up seems to hammer our stands and plant growth. The beans remain clean but crappy. By the time they grow out of it the residual is gone and pigweeds blow through the pathetic canopy.
2) imo valor works so much better HERE. Residual isn't as long, but beans don't get hammered. We put 2.5 oz of valor on pre-emerge. It is important to note that valor + dual/warrant/moa grp 15 products are harder on the young bean. Zidua, thus fierce is best group 15 combo for safety, but not perfect.
I'm thinking rup, 2,4-d, sencor burndown
Pquat, valor (2.5), classic (.33) pre plant/pre emerge
Rup, xtend, dual v2 (if label allows)
