Confirmation of glyphosate-resistant waterhemp (Amaranthus tuberculatus) in New York

Weed Technology
Waterhemp has become a serious management challenge for field crop growers in New York. Two putative glyphosate-resistant (GR) waterhemp populations (NY1 and NY2) were collected in 2023 from two soybean fields in Seneca County, NY. The objectives of this

Preemergence herbicides and postemergence glufosinate applications for green kyllinga (Kyllinga brevifolia) management

Weed Technology
Green kyllinga is a perennial sedge that forms dark green mats that can hinder production activities in specialty crop fields. Seeds of this species are highly viable, and seed dispersal can cause rapid increases in population density.
