Botrytis bunch rot control in South-West France vineyards using a novel bacterial biological control agent and two biocontrol registered products
Résumé
Highlights
•Two biocontrol products, commercialised against Botrytis cinerea, were tested during three growing seasons. Both achieved disease reductions, although highly variable. The product based on potassium bicarbonate showed better performance than the one based on Aureobasidium pullulans
•The field application of the INRA bacterial strain Bacillus ginsenghiumi S38 during two seasons showed promising efficacy results
