Fungicides and insecticides like Ridomil, Omex foliar and Agrinate are recommended to rid off the tubers from the notorious insects like Thrips, Whiteflies and Aphids. Together they cost approximately Sh4800. However plant extracts like Neem and garlic have also been used and proven effective. They are sprayed on attacked plant parts.

Harvesting can be done as from 90 after sowing. The onions are ready for harvest when the leaves collapse. The necks are twisted and its leaves bent over and left to dry for 10 to 12 days or less depending on whether conditions.
The crop is pulled out by hand and kept for some days in the field with bulbs covered with leaves. This is called windowing/curing process. Leaves are then cut off and the mature bulbs stored. Incase of
wholesale production farmers can get a ready market at Wakulima market with the current statistics indicating that the market is heavily under supplied with the highly preferred red onions.
