Abstract
A new copper-based fungicide, a soluble tannate complex of picro-cupric-ammonium formate (PCAF), was evaluated for postharvest control of infections of Botrytis cinerea on rose (Rosa hybrida) flowers. Dip treatments of PCAF significantly reduced disease severity on cut rose cultivars Sonia, Royalty, and Gold Rush during storge at 2.5 C and promoted poststorage fresh weight gain (an index of flower quality). Treatment with 1,000 mg/L of PCAF reduced disease severity to 3% of that on control flowers. PCAF was phytotoxic at 4,000 mg/L. Disease control (depending on the cultivar) was comparable or greater than that achieved with 1,800 mg/L of vinclozolin. Vinclozolin formulation left visible residue on the floewrs, but PCAF did not.This publication has 3 references indexed in Scilit:
