Botrytis control in boysenberries
Each season, botrytis is a challenging disease to control while also complying with residue requirements for customer markets. This challenge is getting harder and was epitomised during the 2021/22 season when long periods of wet weather caused major rot issues for boysenberries. The situation has been exacerbated by the discovery of resistance to existing spray options. Field trials have been undertaken to evaluate four biopesticides for botrytis control.
