A Practical Method for Forecasting Strawberry Anthracnose Caused by Glomerella cingulata Using an Ethanol-spray Treatment in Nara Prefecture, Japan

Abstract

An ethanol-spray treatment was evaluated as a practical method for forecasting strawberry anthracnose caused by Glomerella cingulata in Nara Prefecture, Japan. Evaluations were conducted on latent infections of the pathogen to determine the disease occurrence in commercial strawberry nurseries from 2010 to 2014. The latent infection was highest in early July and corresponded highly to disease occurrence throughout the experiments. The results showed that the ethanol-spray treatment was a reliable and useful method for forecasting anthracnose in strawberry nurseries.
