This may be leftover from infections last year. Please remove by pruning or cutting out infected shoots, branches or limbs. This should be done with sterilized pruning equipment. Sanitize equipment between each cut with alcohol, bleach or heat. If using bleach you must oil any metal parts afterwards. Cut at least 12 inches below lowest part of infected plant part. Sanitize your tools and hands between each time you cut. Remove infected plant parts and put immediately into plastic and do not compost it.
|Infected tissue is black and new growth often dies in hooked growth pattern as can be seen in front of my finger.|
