Exogenous dsRNA trigger RNAi in Venturia inaequalis resulting in down regulation of target genes and growth reduction.

Background: Venturia inaequalis is an apple scab causing fungal pathogen. It is a highly contagious and destructive pathogen which rapidly spreads infection in the surrounding orchards if not managed. The management and control of disease require multiple fungicides to be sprayed at different development stages of the apple.
