Cercospora leaf spot is have by a fungal pathogen of the Cercospora mintage , accord to the Clemson Public Service Activities .

Development

Also attacking other host like barberries , azalea and magnolias , gray mold disease overwinters on plant tissue and spreads sporadically on wind and water from septic hosts to levelheaded hosts . In damp conditions with a temperature range of 32 to 84 degrees Fahrenheit , fungi germinates and infects privet after enter through wound or natural openings in flora surfaces . Anthracnose disease set on twigs and leaves after overwintering in plant detritus and spreading sporadically on piss and wind until landing on maturate host plant life .
