I have two different fields that have a foxtail and crabgrass infestation. One field is pure Alfalfa and the weeds aren't bad, but seem to be growing in number each year. The other field is a Orchard Grass/Timothy mix and has a lot of Foxtail and Crabgrass in it. I saw some posts on here about using Prowl H2O in the spring around March before things come up or are dormant. Field could be muddy in March so February would be better, if that makes sense. Is this something that I can use for both fields or do I need to do something different on each field? I have a 100 gallon 20 foot sprayer that is 3 point mounted with PTO pump that I will most likely be using, if I do something at all. Not high capcity sprayer but these 2 fields are only about 25 acres in total so not a lot to spray. Looking for suggestions on what I can do between now and next baling season to reduce weeds. My Alfalfa is Pioneer Leaf Hopper resistant seed if that matters. The OG is Diaryland.
