Objectives:
1. To determine whether a fall application of Dual Magnum controls yellow nutsedge the
following spring in onions grown on muck soil in New York.
2. To determine onion tolerance to a fall application of Dual Magnum.
If applying Dual Magnum in the fall is effective at controlling yellow nutsedge in onions and does not cause an unreasonable amount of crop injury, we would like to pursue adding this use to the label in New York for onions grown on muck.
Trials were conducted in 2007-2008, 2008-2009 and in 2009-2010.

August 14, 2024
Clarence Center, NY
We'll start this meeting off at Root Down Farm to hear late season disease management updates in peppers and cole crops, plus current best management practices to limit fungicide resistance. Potato variety recommendations and disease control questions in potatoes will be addressed.
Then we'll head to Kreher's beet field to view and discuss alternative weed control technologies. The beet field is an on-farm demonstration of various flame weeding protocols in comparison with stacked tool cultivation equipment. One or two weeding robots will be on-hand for live demonstrations and discussion of the technology's current abilities and future potential. We'll also cover industry updates and a review of late summer disease management in squash.
2.0 DEC credits will be available in categories 23, 1a, and 10.
