Farm Progress Reports


RFR A1505


Muscatine Island Farm


This project was conducted to evaluate new and potential potato herbicides, League and Zidua, in weed management programs. Zidua (pyroxasulfone) is a BASF product now being used in crops of corn, soybeans, and wheat. Currently, Zidua is not labeled for use on potatoes but BASF is planning to expand the label to include the crop in the future. League herbicide, from Valent U.S.A. Corporation, has a supplemental label for potatoes. The active ingredient is imazosulfuron, an ALSinhibiting herbicide that is reported to have pre and postemergent activity against yellow nutsedge, purslane, and pigweeds, and postemergent activity against morning glory.
