PEST MANAGEMENT DECISION GUIDE: GREEN LIST
Coffee berry disease
- Only use seeds and planting material from certified, disease free sources.
- Use of resistant coffee varieties such as Ruiru 11, Batian and BM 139.
- Prune trees after harvest so to open spaces between plants, improve aeration and reduce shade as these can reduce fungal spread.
- Remove old stems as these are more susceptible to infection.
- Control weeds in the plantation and surrounding area to reduce host avalability for the fungus.
- Ensure suitable soil management practices, do not overwater the soil and appropriate application of fertilizer (follow product directions).
- Undertake regular monitoring of crops, especially during wet and cold periods.
- Symptoms of infection include:
- Brown/black spots on berries, may appear sunken in the fruit.
- Lesions on the stalks of young fruit which can cause premature dropping.
- Masses of pink spores visible to the human eye, commonly found on lesions.
- Berries may turn entirely black.
- Consider direct control actions as soon as any symptoms appear in your crop.
- Actively remove infected berries, collect and destroy by burning or burying 60 cm deep in the ground.
- Actively remove weeds and overgrowing plants to reduce shade.
- Graft resitant varieties.
