Beginning in 2020, a screening effort to describe the distribution of herbicide resistance in the state will begin. This coming summer and fall, growers, crop consultants and allied industry personnel who suspect they have herbicide resistance are encouraged to contact SWNY Field Crops Specialist Josh Putman (jap473@cornell.edu, 716-490-5572) to arrange for weed seed collection.

Please share as we are interested to update our database and inform growers of the current resistance situation.
