Dealing with aphids

Aphids form a black sticky substance on fruits, stems and leaves making them shrink and the fruits dry up and rot.

The black substance is most probably a fungal infection, which is as a result of the insects leaving behind a very sweet substance called honey dew. The fungus then attacks the crop. There are various insecticides that you can use, some are systemic and others are contact. You can obtain them from the agrovet near you.

The most effective ones are systemic and they include Thunder and Aster Extrim 20SL. The insecticide should be followed immediately by a copper based fungicide to kill off any spores that are present on the crop.

It is also advisable to keep on monitoring the crop for any pest present to ensure timely management.
