Persistence of fungicide Euparen on strawberry and/or in some canned products of strawberry.

There was studied the persistence of Euparen(dichlofluanid) on strawberry and in some canned products of strawberry, respectively. The rate of decrease of dichlofluanid residues on the leaves of strawberry is proceeding according to the first-order reaction kinetics in the initial 21 days. The content of dichlofluanid residues on strawberry treated twice with fungicide varies from 0.5 to 1.0 ppm, for strawberry sprayed three times from 1.0 to 2.0 ppm, respectively. The significant decay of dichlofluanid residues occurs during the technological procedures applied. The sensoric analysis of strawberry has proved the negative influence of the third spray of fungicide in the initial days. No significance differences between strawberry treated with fungicide and control has been found in flavor and taste of the canned products investigated.
