Burcucumber (Sicyos angulatus) is a summer annual weed resembling cultivated cucumber; the weed is becoming more problematic in agronomic crops. Former graduate student Nick Monnig makes a herbicide application to one of his research plots. MU Weed Scientists utilize GPS tracking collars to determine the effects of weed infestation on cattle grazing distribution. Currently, herbicide-resistant waterhemp fields like this are one of the most problematic weeds in the state.
