Abstract
Fungicides were applied to severely cankered Loring peach [Prunus persica] trees during leaf fall and in early spring to prevent infection of 1 yr old scaffold shoots by L. cincta and L. persoonii. Benomyl and captafol reduced the disease, but captan, dichlone, dichloran, ferbam and S were ineffective. Bordeaux mixture and dinitro-o-cresol were phytotoxic and increased the severity of the disease. Optimum timing of fungicide application was during and immediately after leaf fall. Late summer use of benomyl gave slight control, but spring applications of captafol were ineffective. Fungicide programs were effective for only 1 season. Captafol was equally effective when applied by airblast sprayer in either 850 or 2270 l/ha of spray and comparable to dilute sprays of 5110 l/ha. L. persoonii was the minor pathogen and was almost as well controlled by benomyl and captafol as was L. cincta. Shoot infection can be controlled most economically as a secondary effect of the summer application of benomyl against Monilinia fructicola, and particularly from the application of captafol during or immediately after leaf fall for the control of Taphrina deformans.
