Managing tomato pests and diseases is the biggest challenge for farmers in Kenya. Fortunately, with the right products and timing, you can prevent total crop loss. Below is a guide to the five most common threats and their recommended treatments.
1. Tuta Absoluta
Tuta absoluta is an extremely damaging insect pest that has recently become a severe danger to the Kenyan tomato crop. Because this pest develops resistance to chemicals rapidly, it is notoriously difficult to eradicate. However, by alternating different molecules, you can effectively manage the infestation.
Recommended Treatments for Tuta Absoluta
To stop the “pain” of Tuta Absoluta, rotate these high-performance insecticides:
- Aragon 220ZC
- Emmaron 30SC
- Fenari 120SC
- T-Kab 300WG
- Benocarb 100SC
2. Early and Late Blight
Tomato blight is a fungal disease that causes the rapid rotting of foliage and fruit. Specifically, Early Blight thrives in warm, humid conditions, while Late Blight spreads quickly in wet, misty weather. Consequently, untreated blight can result in an entire output loss in a single season.
Recommended Fungicides for Early and Late Blight
Apply these products early to protect susceptible cultivars:
- Orizole 250EC
- Masta Gold 720WG
- Kenthane 800WP
- I-Perion 50WP
- Tajiri 720WP
3. Blossom End Rot (Calcium Deficiency)
Fusarium wilt is among the most serious tomato diseases in Kenya. It is caused by a soil-borne fungus that can live indefinitely in the soil, often surviving on old tomato debris. Initially, the lower leaves will begin to yellow before the entire plant collapses.
Recommended Control of Blossom End Rot
Effective management requires targeted soil drenching to reach the root zone.
- Foscap Top 250ME
4. Sucking Pests (Aphids, Thrips, & Whiteflies)
Sucking pests—including aphids, leafhoppers, thrips, and whiteflies—consume plant sap from leaves and flowers. Moreover, their feeding causes leaf deformation and significantly decreases fruit set. Therefore, controlling these pests is vital to avoid a complete loss of plant vigor.
Recommended Insecticides For Aphids, Thrips & Whiteflies
Use these products for a fast knockdown and long-lasting protection:
- Vendex 50EC
- Aragon 220ZC
- Acetak Top 700WG
