Congratulations Sachin Dhanda!! All the best with new role!! WKREC Cornell CALS SDSU Extension

My two cents on #invasive grass weeds and their management in wheat. ambrook.com/research/land/… Cornell CALS Cornell Cooperative Extension

First MPS student (Max Rieley) graduated today. Congratulations Max!! I wish you all the best with your future endeavors (vice president in investment bank in Boston). Cornell CALS Cornell University


#Waterhemp is rapidly spreading invasive #pigweed in the NYS. Reported in 22 counties and most of these populations are glyphosate-resistant. We are evaluating #IWM strategies for its effective control Cornell CALS Cornell Cooperative Extension New York Corn & Soybean Growers Association Cornell AgriTech


Spring wheat trial got sprayed before rain Cornell CALS campus farm. We are testing Tolvera herbicide alone or in combinations for crop safety and broadspectrum weed control. Stay tuned! Cornell Cooperative Extension


All corn and soybean studies got planted. Great team work by graduate students Preetaman Bajwa Henrique Scatena, Midhat Tugoo & summer interns. Testing effective #IWM startegies. Cornell CALS WSSA GROW.IWM Northeastern Weed Science Society


Glyphosate-resistant marestail is a significant challenge for no-til soybean producers. We will be testing alternative burndown chemistries that can be used to control glyphosate-resistant marestails in Enlist soybean. Stat tuned !! Cornell CALS Cornell Cooperative Extension


POST applied #Tolvera (tolpyralate + bromoxynil) herbicide providing excellent control of common ragweed and common lambsquarters in spring wheat at 14 days after application Cornell CALS Cornell Cooperative Extension Corteva Agriscience


Annual rye cover crop termination with glyphosate (Roundup), glufosinate (Liberty), paraquat (Gramoxone) and quizalofop (Assure II) at 21 days after applications on a grower field. Enlist beans were planted at termination timing.Cornell CALS Cornell Cooperative Extension





Glufosinate + glyphosate tank mix causing injury on #Enlist soybeans when got sprayed in early growth stage under cool and wet conditions Cornell Cooperative Extension


Advantage of using #preemergence herbicides to control glyphosate-resistant #waterhemp in soybeans. On-farm study looking at various PRE and POST combinations for waterhemp control in central #NewYork Cornell CALS Cornell Cooperative Extension


Zap! A study by SIPS Postdocs researchers in test plots of East Coast peas, beets and spinach found that laser weeders worked as well as common herbicides, with reduced crop stunting and increased crop biomass. Krishna Ramanujan news.cornell.edu/stories/2025/0…

Attending spring cereal grains and forage field day Cornell CALS campus farm. Lot of great info on new varieties in spring/winter cereal grains by various breeding programs Cornell Cooperative Extension



Severe soybean injury from PPO inhibiting herbicide (group 14) applied with glyphosate 6 days after foliar application Cornell CALS research farm. Weed control looks excellent though.



Glyphosate-resistant #waterhemp is exploding in central #NewYork field crops this year due to wet spring and large soil seedbanks Cornell CALS Mike Hunter 🇨🇦🇺🇸 Lynn Sosnoskie 🇺🇸🇨🇦 Cornell Cooperative Extension WSSA
