Injury of the heads was found to be necessary for the infection of sunflower (Helianthus annuus L.) by Rhizopus arrhizus Fischer, identified as the causal agent of a soft rot. Infection did not take place before flowering. Birds visiting the heads in search of seed were implicated in the spread of the disease. The disease was controlled by a single application of Copper 8-quinolinolate.
