The state of Virginia has an active program of identification of boxwood blight. Does Maryland have a similar program If so, how do I contact it?
Montgomery County Maryland
Here is our page on boxwood diseases, including boxwood blight. https://extension.umd.edu/hgic/topics/boxwood-culture-and-diseases-including-boxwood-blight It is not too hard to identify boxwood blight yourself, but you can take photos and send it in here for identification, too. Our plant pathologist will take a look at it. Send in close ups of leaves, stems and also the whole plant.
Leaves infected with blight quickly drop, which is different from other diseases they get.
