Perennial sow thistle has increased in economic importance and has become a serious weed problem for muck onion growers in the Western region on New York. In this project, we investigated fall chemical burn down strategies to manage this weed, as well as the use of a synthetic auxin growth regulator type herbicide, trade name Stinger to manage this weed in-season within an onion crop. Crop tolerance to Stinger was also studied.
Following is the FINAL report and the first of 3 complimentary power point presentation files.
