Dissipation behavior of pesticides applied in multiple treatments in apples

Abstract

The main objective of this work addresses kinetic studies on the dissipation of 12 pesticides applied in single recommended doseand double dose treatments in apples, considering 6kinetic models which determine the statistical parameters describingpesticide behavior, including their half-lives. The half-lives of pesticides in apples at BBCH (Biologische Bundesanstalt, Bundessortenamt and CHemical industry) scale 76-79 resultedfrom the linear regression equations considering single dose treatments were between 0.01 days (for λ-cyhalothrin) and 74.90 days (for myclobutanil).Data on the rate of dissipation and half-lives of pesticides in various plant compartments are particularly significant for pesticide monitoring and human health impacts and risk assessment.
