Silver Tip

Special fire blight spray. Where fire blight was severe last year, applying a copper spray at silver tip will aid in reducing the amount of bacteria available for infection later in the spring and summer. Do not apply copper to apples after 1/4-inch green leaf stage or when drying conditions are slow, as severe injury can occur. Copper and its residue have many compatibility problems with other pesticides. Refer to Part II: Diseases, Pests, and Natural Enemies.
