Residue of pesticides (acetamiprid, pyribencarb, and boscalid) in an applicator after rinsing

Abstract

The residue of pesticide inside a power sprayer and a water tank were measured after washing with water. After spraying pesticides (acetamiprid, pyribencarb, and boscalid), we rinsed the applicators five or six times and analyzed cleaning solution samples with LC/MS/MS. More than 90% of the pesticide residues in the power sprayer and tank were removed after rinsing two times. There tended to be more pyribencarb and boscalid left in the apparatus compared with acetamiprid.
