Glyphsoate and Dicamba Drift Problmes in Potatoes

The introduction of crops resistant to glyphosate and dicamba is concerning for potato growers. These herbicides can reduce yield and quality and cause problems in tubers sold for seed. The purpose of this study is to determine the effects of glyphosate plus dicamba on plant injury, marketable yield, and the effects on seed tubers planted the following year. Glyphosate in seed potato can cause a delay in emergence, multiple stems, and malformed leaves. Dicamba can cause a delay in emergence and malformed foliage. Protect potatoes by talking to neighbors, dedicating a sprayer for potatoes, planting borders, and scouting field regularly.
