Uptake and translocation of pesticides in pepper and tomato plants.

ABSTRACT:

Background

In this study, field and greenhouse experiments were done with spray application of the insecticides acetamiprid, indoxacarb, deltamethrin, λ-cyhalothrin, spinosad, chlorantraniliprole on pepper and tomato plants. Results were interpreted with numerical modeling.

Results

Observed fruit concentration dynamics could be described overall well by modeling. After application, concentrations decreased in pepper and (slower) in tomato fruits (lower degradation and dissipation for tomato). Chemical input to individual above-ground compartments (fruit, leaf, stem, soil), arising from spray, was among the unknowns and hence estimated. Input to fruits was estimated 1-13% and 1-17% of the total applied amount; input to stem, leaf and/or soil 0-13% and 0-26% (pepper and tomato
