Cause The OSU Plant Clinic has found Ascochyta sp. and Pleospora sp. in association with leaf spots of skimmia. Leaves may become wet for extended periods of time in the shade, which is favorable for leaf spotting organisms. These plants are shade loving and may become chlorotic due to poor, dry soil, overexposure to the sun or mites.
Symptoms Size, shape or color have not been recorded or described.
Cultural control
- Space plants for good air circulation and to promote drying under wet conditions.
- Remove infected, dead, and dying leaves on and near plants.
Chemical control No chemicals are specially registered for this crop and none were found in the IR-4 research database. Many can be effective and legally used. Test first on a small section before applying on the whole plant to evaluate possible phytotoxicity.
