Herbicide Resistance Update on Marestail
Joshua Putman, Field Crops and Forage Specialist
Southwest New York Dairy, Livestock and Field Crops Program
Horticulture Weed Scientist, Dr. Lynn Sosnoskie, has been conducting some interesting research over the past few months. Extension specialists from all around the state collected and submitted weed specimens last fall for herbicide-resistance testing to better understand the best management practices for these weeds in field crops. We now have preliminary results from the first screening on horseweed aka marestail. Thirty populations have been tested so far and, it appears, that 27 out of 30 have resistance to the field-use rate of glyphosate (Roundup). Testing will continue with different chemistries so that we can provide growers with proper control measures. Join us next week for the Field Crop Series where we will cover topics on weeds, diseases, and insects in further detail.
