Allergic dermatitis from a new pesticide

In four patients suffering from allergic contact eczema, the risk of sensitization to a new residue-leaving fungicide (Plondrel) used in spraying roses is considered. Two patients, however, were probably also sensitized to materials from the roses themselves. By gas-liquid chromatography the amount of the fungicide, especially in the leaves of roses, appeared to be rather high. The role of pesticides has to be considered when sensitizing agents of plant dermatitis are investigated.
