Résumé
Since 2014, the tomato leafminer has become the most serious threat to the sustainable productivity of tomato in Kenya, causing up to 80% yield loss. Almost 98% of farmers’ crop suffer from this pest and when using pesticides as a control method, only 27% of farmers report success. Building on CABI’s expertise in biological control and integrated pest management, in this project, CABI is collaborating with Koppert, a global supplier of biological control products, to demonstrate to farmers, the benefits of biological control within an integrated approach.

Présentation
CABI has promoted the use of biological control and integrated pest management since its origin. CABI will work, collaboratively, with Koppert, a leading global supplier of biological control products, to demonstrate biocontrol within an integrated approach.

For two seasons, CABI and Koppert, together with smallholder tomato growers from Nairobi and Kajiado counties, will implement an Integrated Pest Management (IPM) approach involving the predatory mirid Macrolophus pygmaeus (MIRICAL) and the pheromone trap system (Tutasan and Pherodis) with the hope that by using this spectrum of methods, pesticide use will be reduced and yields increased. This builds on previous work conducted by Koppert and Kenyatta University to validate the use of pheromone traps for T. absoluta. Work will involve deploying the two techniques in open fields and greenhouses.

One problem encountered is the attitudes of smallholder farmers towards biocontrol in that itis perceived as being expensive, not readily available and not always as effective as synthetic pesticides. This project, will contribute to making that change, through enabling farmers to try out biological control, experience the benefits, and provide lessons and evidence for furthering the uptake of low risk pest control products. Biological control learning sites will be set-up to act as information hubs and focal points for communities to learn and be trained on biological control.
