During the growing season, SDSU Extension provides weekly production recommendations.
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.
When controlling grassland weeds, the mindset of row crop weed control may be put into practice too often. In most cases, broadcast control of weeds in grasslands is rarely necessary. Most often, spot treatment can be used more effectively to manage the noxious and invading weeds.

With the rise of herbicide-resistant weeds, the use of an adjuvants is also on the rise and may be necessary to help control resistant weeds.
Crop damage could occur if sprayer clean-out is overlooked or not properly conducted. It is critical to always follow the procedure specified on the herbicide or commercial cleaner label to completely remove herbicide residue from the sprayer system.
Producers need to plan in advance on how to deal with bare fields that contain an overabundance of weeds. Weeds in these fields have deposited significant amount of seeds on the soil surface, which can easily germinate when adequate moisture and temperature are available.
