Fungicides for Control of Anthracnose on Annual Bluegrass Greens
Summary: In a replicated field trial at San Diego Country Club, Chula Vista, CA, monthly applications of Heritage at 0.2 and 0.4 oz/1000 sq ft and Lynx at 1.5 oz/1000 sq ft provided excellent protection against anthracnose (Colletotrichum graminicola) attack on annual bluegrass greens when compared to Bayleton at 4.0 oz/1000 sq ft or the non-treated control plots. Less than acceptable performance of Bayleton may have been due to the monthly application interval (as opposed to a biweekly application interval).
