In East Africa, the cultivation and sale of vegetables plays a vital role for the population. However, vegetable production is severely affected by infestations of plant pests and diseases. To meet this challenge without chemical pesticides, a gentle, ecological solution is being applied. Together with experts from partner organisations, vegetable farmers develop and validate biological, integrated pest controls. The most important vegetable pests are controlled with push-pull systems, beneficial insects, parasitic fungi, biopesticides and the use of resistant, indigenous vegetable varieties.
