  • Other pests and diseases: ask before you treat

    The source also lists chemical treatments for black-headed caterpillar, eriophyid mite, basal stem rot, bud rot and stem bleeding, including root feeding and crown sprays. Some require not harvesting nuts for a period after treatment. Choose any treatment only with your local Horticulture or Agriculture Officer.
