In Saint Lucia, farmers are increasingly facing the yellow curly leaf virus as an emerging hazard, affecting their livelihoods. Pests and diseases can seriously damage farmers’ crops and reduce their yields. Farmers were getting apprehensive about continuing with tomato production in the way they did in the past, due to the increasingly high cost of chemical treatment against the virus and the uncertainty of crop yields. The integrated pest management method introduced by the project, in both open fields and in a greenhouse, showed that when exact chemical application schedules and quantities were applied and recommended crop husbandry practices were followed, the incidence of tomato curly leaf virus was reduced and crop yield, as well as quality, could be improved.
