Branch and twig borer
Identification tip: Wilting shoots may indicate branch and twig
borer activity (if it is accompanied by a hole at the base of
Botrytis bunch rot
Identification tip: If you see wilting, look for a lesion at
the node of the shoot. Try to break or cut the shoot in the region
between the flaccid areas and the adjacent area with normal turgor.
Brown discoloration on the cut surface is evidence of Botrytis.
Identification tip: Newly emerging shoots displaying malformed
foliage, stunting, and a white powdery or dusty appearance indicate
an overwintering bud
infection by powdery mildew.
