- Innovative weed control strategies using older and new chemistries to address palmer amaranth, horseweed (marestail), ragweed, waterhemp and glyphosate resistant kochia, pre/burn-down and/or post emerge. Including, any future newly registered desiccant active ingredients.
- Weed species shifts, due to resistance/tolerance to common modes of action need to be considered for burn-down uses, as well as existing post systems like Clearfield®and Express®Sun. This priority could include burn-down product safe planting interval definition for all effective herbicides, including older products like 2,4-D, as well as preservation and MOA resistance management for the post-emerge Group #1 grass products. Group #1 additive strategies might include pre-plant, pre (and/or) early post application of non-group #1 MOA’s. Foxtail, brome species and non-Group #1 wild oat options need to be better defined and demonstrated for sunflower producers.
- Interest in innovative weed control techniques related to existing labels and to test experimental or new-to-market herbicides and use of weed seed free cover crops for potential sunflower application. More research may need a fall applied timing data & demonstration focus, vs. current spring season only weed control, to reduce spring emerging populations. Fall herbicide timings, both residual products and burn-down chemistry, might enhance control compared to standard spring/summer only, strategies.
