Botrytis cinerea causes the major grapevine disease botrytis bunch rot. This disease is traditionally controlled through cultural practices to create conditions that are unfavourable to the disease combined with fungicide applications. The use of fungicides, particularly at the end of the growing season, is facing barriers due to concerns about chemical residues and resistance of the pathogen to fungicides. The use of biological options to control unwanted pathogens is an emerging alternative. This webinar will explore the challenges of using biologicals in viticulture, with a panel of experts from the companies supplying products discussing how to get the most out of them.
