On-Farm Trials Reveal Significant but Uncertain Control of by and Potassium Bicarbonate in Organic Grapevines.

, a fungal pathogen that causes gray mold on grapes, can decrease yield, substantially reduce wine quality, and therefore cause significant economic losses. In a context of increasing awareness of environmental and human health, biopesticides are a potential alternative to synthetic chemical treatments to produce grapes and wine in compliance with high food standards. However, the effectiveness of biopesticides is not well known and more research is needed to help winegrowers assess their ability to control wine diseases.

Microbial Antagonism Toward Bunch Rot of Grapes in Multiple Field Tests Using One Strain and Formulated Biological Control Products.

bunch rot (BBR), caused by the necrotrophic fungus , is a major disease of wine and table grapes worldwide. Due to negative effects of pesticides on the environment and human health, alternative control strategies against BBR, such as biological control agents (BCAs), are required to produce high-quality grapes and wines with high standards of food safety. However, few biological control products against BBR are available, and their efficacy is sometimes variable.
