Q&A Home

Jack from Abilene, Tx. writes,

Will Revolver Selective Herbicide work in temperatures varying between 25-50 degrees?

Will it be effective on poa annua now, or should I wait? I don't want poa annua to get established.


According to the manufacturer  "For best results to control mature weeds, apply in spring or through fall when the daily average temperature is above 70 degrees." When the plants are not actively growing or they have gone dormant, selective herbicides like Revolver are not very effective.
