ITHACA, N.Y. — The Field Crop Weed Identification and Control Series kicks off in February of 2022. Webinars will run into March, and cover a range of issues concerning weed management and identification. More information about individual events and webinars can be found below.
February 2, 2022, Broadleaf Weed identification for crop production 12-1 pm (virtual) Bryan Brown NYSIPM.
Many of our most problematic weeds are broadleaf weeds. The best way to control them varies depending on the species, so it is imperative that weeds are identified correctly. In this session we’ll go over some of the key distinguishing characteristics of the most problematic broadleaf weeds in NY field crops. For each species, we’ll discuss some of the biology that makes it weedy and look for potential “Achilles heals” that can be exploited for management. We’ll also review best practices for using smartphone weed ID apps.

February 16, 2022, Grass Weed identification for crop production 12-1pm (virtual) Caroline Marschner, Ext. Assoc. Weed Ecology, Cornell
Identifying grass and grass-like weeds can be challenging but, is necessary for good weed management. During this program we will discuss what traits to look for when identifying grasses, go over some of the common crop grass weeds, and share some resources for grass weed management.

February 23, 2022, Weed management in corn 12-1pm (virtual) Jeff Miller, Resource Educator, CCE Oneida County.
Weed control is an integral part of corn production. Cultural and chemical control methods should be incorporated in an integrated approach to control weeds. Cultural practices like crop rotation, tillage, and cover crops will be discussed. Herbicide families (site of action) efficacy, timing of application will be discussed for annual grasses and broadleaf weeds, perennial grasses, perennial broad leaf weeds and herbicide resistant weeds.

March 2, 2022, Weed management in Soybeans 12-1pm (virtual) Mike Hunter, Regional field crop specialist, CCE North Country Regional Ag Team
Implementing integrated weed management practices in soybean production will be the focus of this presentation. Mike Hunter will share results from three years of on-farm soybean herbicides trials in New York State. He will provide the current status of herbicide resistant weeds in New York, and discuss effective herbicide resistant weed control strategies and how to manage resistant weeds on your farm.

March 9, 2022, Weed management in hay and pasture 12-1pm (virtual) Janice Degni, Team Leader and Field crops specialist, CCE SCNY regional team
Weed Control for Hay Crops and Pastures
This session will provide a review of cultural and chemical weed control practices for clear alfalfa or grass, mixed stands, and pasture. It will include practices that give the hay species a competitive edge over weeds and herbicide options for different weed scenarios. Common difficult to control weeds in pasture will be covered as well as improvement of older hay stands with weed invasions.

March 16, 2022, Alternative weed control and weed seed management 12-1pm (virtual) Lynn Sosnoskie, Asst. Prof. of weed ecology and specialty crop systems, Cornell
Weeds are a significant threat to crop production due to 1) competitive interactions that limit yield potential, 2) physical interference that reduces harvest efficiency, and 3) serving as an alternate host for pests and pathogens. The evolution of herbicide resistant weeds (in particular marestail/horseweed/Canada fleabane, Palmer amaranth, waterhemp) further complicates weed control efforts by limiting the utility of commonly applied chemical tools. This talk will focus on the current state of herbicide resistance in NY and the future of chemical weed control. Novel weed management strategies, such as harvest weed seed control (HWSC) and electrical weeding will be discussed and recent research updates provided. Best management practices for suppressing unwanted vegetation, including combine and equipment clean-out to limit seed spread, will also be presented.
