Impact of two nano-pesticide formulations in combating the two-spotted spider mite, Tetranychus urticae Koch, and their residues in cucumber fruits, Cucumis sativus L

Scientific Reports
Nano-pesticides aim to improve the efficacy and safety of conventional pesticides, but as they are still in the early stages of development, data about their environmental fate is insufficient.
