Last year, Bayer announced they would be phasing out glyphosate from the homeowner market, but they would be keeping the Roundup name for future marketing. Learn some important label considerations when purchasing Roundup-branded products.
How does spring flooding impact weed seed movement and dispersal? The flooding that is occurring from spring snow melt may cause weed seeds that are on the soil surface or eroded soil to move, and possibly long distances.
Long residual pre-emergent or early post-emergent herbicides may cause stand reduction or complete failure of cover crops. Depending on efficacy of the herbicide, each situation can both affect in-season and/or post-harvest cover crop establishment.
As the spray season starts, it is always good to be aware of resources and testing facilities where you can send in possible herbicide-affected plant samples. SDSU Extension offers suggestions on how to handle possible herbicide damage situations as well as recommended labs that receive plant matter samples to test for herbicide residues.
Consider pre-harvest herbicide applications in crop ground planted with small grains that are grown for seed or forage. Dense weed populations may inhibit harvest, therefore proper control of them early in the growing season is best.
This is a quick reference guide to common herbicides and their rotation restrictions for selected crops.
Increased use of cover crops following major crops brings up questions of herbicide effects on cover crop establishment and rotation restrictions. Learn some considerations for cover crops following wheat.
