Abstract
Dinitrophenols and their esters are used as insecticides, acaricides, ovicides, herbicides, and fungicides. Residues of these pesticide chemicals are generally determined as the parent phenol, after saponification when necessary, by methods which normally do not detect many related compounds, such as those that might form by biological or photochemical oxidation or reduction. Since the photochemistry of dinitrophenolic pesticide chemicals is poorly understood, it is important to develop the information needed to interpret the data obtained in studies on the persistence and toxicology of residues on or in food and feed. Accordingly, cl4-1abeled preparations of 2-see-butyl-W,6-dinitrophenol (dino~eb, DNBP~and its isopropyl carbonate (dinobuton, AcreX~, Dessin~ were exposed to sunlight on growing bean foliage in order to determine the nature of the persisting residues.
