Scab prevention: accelerating leaf decomposition to reduce ascospores

Preventive measures for scab in organic apple and pear orchards focus on reducing overwintering ascospores by accelerating leaf decomposition. Strategies include promoting earthworm activity, using leaf collection nets, and mechanical leaf collection. These methods target the disease reservoir to lower infection pressure in subsequent seasons. Features insights from Gerjan Brouwer (Delphy) and organic grower Pieter Jans Jansonius.
