The nation of Sudan has been spending huge sums of money importing chemical crop protection. But it seems like local farmers have found a natural alternative: Basil (Ocimum basilicum).
Crop farmers in the extensive rain-fed farmlands of the Aldali and Almazmoom regions have discovered that basil, which grows wild within their farms, can be used to repel malaria-carrying mosquitoes. The farmers simply burn dry basil plants to create incense that drives away the pests. The farmers have equally used the incense thus obtained to repel other pests that destroy their crops.
This discovery has inspired scientific researchers to concoct pesticides from this plant. In collaboration with a US research institute and with funding from Saudi and Egyptian companies, researchers have extracted basil seed oil and with certain additions, have managed to produce an effective mosquito repellent.
