Farmers of the Sugar River, a farmer-led watershed protection group, recently held a workshop featuring proper use of sprayers and nozzles. The event also addressed the residual effect of herbicides impeding fall cover-crop establishment.

Demonstrations featuring different surfactants, oils and adjuvants helped farmers understand the ways in which the inputs differed and how they could be used together. A spray table enabled farmers to see differences in droplet size and dispersion from various nozzles, even with the same volume of water being used. Farmers were advised to run water through their sprayer systems to ensure nozzles and hoses are operating correctly before incorporating herbicide. Considering and possibly adjusting herbicide programs is critical to ensuring cover-crop establishment in the fall, according to the speakers.

Farmers of the Sugar River is working to encourage other farmers to adopt conservation practices such as no-till and cover crops, to reduce sedimentation in streams and rivers. The farmer group hosts events to educate producers on how to adopt such practices. The workshop was held near Monroe, Wisconsin. Representatives from Helena, BASF, Corteva and Midstate Equipment provided presentations.
