PEST MANAGEMENT DECISION GUIDE: GREEN AND YELLOW LIST
Anthracnose on pepper (Colletotrichum acutatum)
Prevention
- When planting use certified seed or disease free seedlings.
- The seeds can be treated to reduce the chance of disease by soaking in hot water (50°C) for 30 minutes before planting.
- If the disease is present in the field, pepper should be rotated with crops other than tomatoes, eggplants or potatoes for at least three years.
- If irrigation is used only water in the morning so the plant can dry before nightfall.

Monitoring
- 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.
Direct Control
- 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)

Restriction
- WHO Class III (Slightly hazardous)
Timing: apply when the plants start to flower or when conditions are favourable for the disease (wet and warm). Spray maximum of 3 times per season PHI: A pre-harvest interval of 14 days should be observed. REI: Avoid entry into the field 2 days after application.

How do I prevent Fusarium wilt,verticillium wilt and bacteria wilt of tomatoes.
To prevent either bacteria, verticillium or fusarium wilt, please consider the following,
1. solarisation of nursery bed before planting to effectively reduce the bacteria or fungi population.
2. remove and burn plant debris after harvest to reduce inoculum pressure in the soil.
3. plant on raised beds or ridges to improve drainage.
4. reduce injury to crop roots as wounds are entry points of wilt pathogen.
5. avoid planting on land with history of wilt disease.6
6. practice long crop rotation for 4-6 years with cereals or legumes (maize, millet, sorghum or cowpea)
7. sterilize garden or farm tools after working in infected soils with fire.
8. extract seeds from healthy fruits.

My dad is a vegetable farmer (egg plant, okra and pepper). Pest and disease control is becoming a problem. Even when he applies pesticides and disease control chemicals, the disease does not go but hides and spring up later as well as the pests. What can he do to stop this?
Thank you Bernard.
Several factors could be the cause. Consider these points to help control the incidence of diseases and pest on your Dad’s vegetables.
- use certified and disease free seeds
- practice crop rotation and land rotation if possible
- uproot and burn affected plants
- scout regularly to detect diseases and pest around the farm.
