Recommended Posts

a number of young hollies (Ilex aquifolium) that were planted this year and are partially or completely defoliated. In most cases the defoliation appears to have affected the upper half of the young trees more than the lower. There are also purple/mauve (turning brown/black) lesions present on the stem and around the buds. Could this possibly be Phytopthora ilicis

 

:thumbup: : Phytophthora leaf & twig blight caused by the oömycete P. ilicis.
