Application Details • Research indicates Poa annua germinates most rapidly when soil temperatures and rainfall average ≤ 66°F and 0.5” for a period of seven days (Taylor et al, 2021). • Ideal timing for first granular application varies by location and individual site conditions. Make split applications at 4-to-6-week intervals. • Build your own liquid mix by combining Tower herbicide plus a residual preemergent herbicide and a postemergent herbicide from the list of options below. Make one application between Oct 15th and Dec 1st.
