- Scout the field once a week checking for symptoms on the leaves and fruits.
- Symptoms on the fruits appear as circular dark sunken lesions with concentric rings on the immature and mature fruit.
- Lesions can also be seen on the stems and leaves as irregularly shaped brown spots with dark edges.
- Consider carrying out early control when more than one lesion is seen on any individual plant.
- Remove any diseased plants and fruits from the field and either bury or burn them.
- When using a pesticide or botanical, always wear protective clothing and follow the instructions on the product label.
- Do not use chemicals with the same mode of action year after year as this can lead to resistance.
- Always consult the most recent list of registered pesticides.
- Apply Mancozeb (Ivory 80WP, Foko 80% WP or FokoSuper 80% WP) as a protectant fungicide at a rate of 100-150g per 16-litre knapsack sprayer Protectant fungicide with a multi-site mode of action (FRAC group M3)
