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.

Is Grazing Sheep Beneath Solar Arrays and Opportunity for Your Future?
September 25, 2023
Mt. Morris, NY
Grazing sheep beneath utility-scale solar arrays can build wealth of present and future sheep farmers as vegetation management service providers and access to additional pasture. The Cornell Cooperative Enterprise Program (CEP) conducted a survey earlier this year completed by over 600 farmers. Farmers identified barriers to grazing sheep under solar arrays and weighed in on need for a producer-led organization to negotiate contracts on their behalf, coordinate logistics of multiple flocks, provide transport of sheep to and from the site, care for sheep while on-site, and provide supplemental mowing. Additional questions focused on processing and marketing needs.
