For the most part, late spring and early summer this year has been reasonable, weather-wise. So goes the weather, so goes the turfgrass. So far, the turfgrass submissions to the Plant Diagnostic Laboratory have been slow and steady… until last week, that is. Golf turf suddenly realized it was summer and the party started with some dollar spot.
Golf Turf Disease of the Week: Anthracnose Basal Crown Rot
Surprise, surprise! Our old friend anthracnose basal crown rot just came home to roost! An unexpected influx of putting green samples diagnosed with anthracnose were submitted to Rutgers Plant Diagnostic Lab this week.
The Emperor has No Clothes
Have you noticed in the landscape that the sycamores, and to a lesser degree, the plane trees are devoid of leaves? Anthracnose of Platanus species is a well known disease in our area. The disease causes leaf and shoot blight, twig cankers, and branch dieback, and has been particularly severe this spring.
Blister in the Sun
Leaf blister on maple? You say no way, leaf blister only gets on oak… A foliar disease that looks very much like anthracnose has appeared on area red maples in the last few days.
