Dissipation of triadimefon on the solid/gas interface

The dissipation or triadimefon, as pure solid and in the Bayleton 5 commerc ial formulation, was studied under controlled and natural conditions. Volat ilization and photodegradation were shown to be the main dissipation proces ses. The volatilization results can be described by an empirical model assu ming exponential decay of the volatilization rate. The filler of the commer cial formulation is determinant for the volatilization but has little effec t on the photodegradation rates. The main photoproducts were identified and a reaction mechanism proposed. (C) 2001 Elsevier Science Ltd. All rights r eserved.
