Quantification of pesticide dosage and determinants of excessive pesticide use in smallholder vegetable production systems in Tanzania.

ABSTRACT: The use of pesticides for diseases and insect pest control has become a key component in smallholder vegetable production. This study therefore quantified the concentration of pesticide active ingredient per unit production land (kg a.i/ha), and drivers of increased pesticide use in smallholder vegetable production systems in Tanzania. Through field surveys and observations, data were collected from 385 farmers from Iringa, Arusha, and Kilimanjaro regions. A binary probit model was used to derive factors fostering increased pesticide use. High dose rates with increased frequency of application were evident. The concentrations of active ingredients (kg a.i/ha) were far above the world averages for fungicides (17.18 kg a.i/ha in tomato and 13.05 kg a.i/ha in onion), insecticides (5.86 kg a.i
