Evaluation of OMRI-Listed Fungicides for Anthracnose Control in Watermelon in Geneva, NY, 2024
Anthracnose, caused by the fungus Colletotrichum orbiculare, is a devastating disease affecting watermelons ( Citrullus lanatus) and other cucurbits. Disease symptoms begin as small, brown lesions that progress to oblong-shaped, reddish-brown lesions on leaves and vines and rapidly lead to defoliation. Symptoms on fruit are sunken lesions that appear salmon pink due to conidial masses. The objective of this study was to evaluate the efficacy of selected OMRI-listed fungicides for use in organic watermelon production in New York in 2024. Oso was the sole fungicide that provided control of anthracnose.
