NY Herbicide Resistance Survey

With the recent documentation of evolved herbicide resistance in New York, including Palmer amaranth (glyphosate, ALS-inhibitors), waterhemp (glyphosate, ALS-inhibitors), horseweed (glyphosate, ALS-inhibitors, paraquat), lambsquarters (bentazon), Cornell wants to better understand the current "state of the state" with respect to herbicide performance and failure. Specifically, we are surveying growers/land managers/crop consultants/extension specialists/industry personnel, across cropped (e.g. agronomic, vegetable, fruit), ornamental/horticultural (e.g. Christmas tree farms, golf courses), and non-cropped (e.g. industrial, roadsides) systems in NY to describe the distribution of herbicide resistance in the state. This survey is VERY SHORT and should be QUICK to answer. It is also COMPLETELY ANONYMOUS. Your responses will help Cornell weed scientists plan future research and extension projects. Please access the survey using the link below:

New Publication on Growing Pawpaws

Are you a fan of pawpaws? These custardy fruits can be hard to come across, so this guide provides information on how to grow your own pawpaw from seed, and how to care for grafted seedlings. Pdf on growing now available.​|crops|unusual_fruit|crop*50

New Weed Management Technology Survey

Want to move away from herbicide reliance? Are you using novel technologies to manage weeds? We want to know about it to inform our weed science research. A team of weed scientists from University of California Davis, Oregon State University, and Cornell University are asking berry, tree fruit, tree nut, and vine crop growers to take 5 to 10 minutes and answer this short and anonymous survey.
