Aphids control is a constant requirement for Kenyan farmers growing vegetables, fruit trees, and flowers. These small, soft-bodied insects cluster on new shoots and leaf undersides to suck vital sap. This not only stunts the plant but also results in the excretion of “honeydew,” which leads to the growth of black sooty mold and the transmission of plant viruses.
Target Crops & Damage Symptoms
To achieve effective aphids control, you must identify these common signs of infestation across your crops:
Brassicas (Sukuma Wiki & Cabbage): Leaves become curled, thickened, and yellowed. You will often see dense colonies of greyish-green aphids crowded on the growing tips.
French Beans & Peas: Sucking damage causes stunted growth and distorted pods. High populations can cause the plant to wilt and die prematurely.
Fruit Trees (Citrus & Mango): Watch for distorted new leaves and the presence of ants, which “farm” the aphids for their sweet honeydew.
Tomatoes: Aphids act as carriers for mosaic viruses, which cause mottling and stunted growth even when the pest population is low.
Prevention and Aphids Control
Managing aphids requires a combination of monitoring and good field hygiene:
Monitor for Ants: If you see ants climbing your plants, it is a sign of a hidden aphid colony. The ants protect the aphids from natural predators.
Yellow Sticky Traps: Use yellow traps to catch winged adult aphids as they fly into your crop to start new colonies.
Weed Control: Remove weeds like black nightshade (Managu) and pigweed from around your fields, as they act as a “safe haven” for aphids.

Aphids Control FAQ
Q: What is the best Kenagro product for aphids control?
A: Acetak Top 700WG is the premier choice. Its systemic action ensures that even aphids hidden under curled leaves are eliminated, while also preventing the spread of viruses.
Q: Why are my plant leaves covered in black soot?
A: This is Sooty Mold growing on the honeydew produced by aphids. For effective aphids control, use Acetak 200SL to kill the pests; the mold will eventually stop spreading once the honeydew source is gone.
Q: How often should I spray for aphids?
A: Spray at the first sign of a colony. For heavy infestations, repeat the application every 7 to 10 days, ensuring you rotate between systemic and contact products like Alfatox 100EC to prevent resistance.
