2023 Survey of Most Common and Troublesome Weeds in Grass Crops, Pasture, and Turf |
Introduction
Thank you for participating in the National and Regional Weed Science Societies survey of the most common and troublesome weeds in the U.S. and Canada. Your expertise is important and will be invaluable in highlighting weed species trends over time.
We would like you to list the five most common and troublesome weeds for as many of the grass crops as you feel comfortable with. This year, we will be surveying weeds in:
1) Corn
2) Rice
3) Sorghum
4) Spring Cereal Grains
5) Winter Cereal Grains
6) Pastures, Rangeland, Other hay
7) Turf
Common weeds refer to those weeds you most frequently see.

Common weeds refer to those weeds you most frequently see.
Troublesome weeds are those that are most difficult to control (but may not be widespread).
When listing your weeds, please be as specific as possible, i.e. use the Latin name according to the Weed Science Society of America's Composite List of Weeds: http://wssa.net/weed/composite-list-of-weeds/

Please feel free to complete the survey multiple times for the same crop category if there are different weed populations for crops in that category.
