Weed Resistance Management Demonstration and Plot Tour

Tuesday, July 23, 2019 at 1:00pm to 3:00pm

Quinten Good's Farm - Parking at J. Martin Auctions 1036 State Route 318 Waterloo, NY 13165

Come join us on July 23 in Seneca County at Quinten Good's farm for a demonstration and walking tour of 16 different pre- and post-emergence treatments in soybean and 12 different treatments and combinations in corn.

  • Tall waterhemp and marestail are two weeds that are resistant to glyphosate and ALS herbicide modes of action in the WNY and Finger Lakes regions.
  • Each year the number of acres with resistant weed populations expands.
  • For herbicides to be an effective tool in weed management, we have to know what chemistries & application timings are most effective against these resistant weeds.

1:00 - 1:15 Update on Current Status of Waterhemp and Marestail in NY, Mike Stanyard, CCE/NWNY Team
1:15 - 1:30 Waterhemp Resistance: Results of Spray Chamber Mode of Action Study , Bryan Brown, NYS IPM Program
