| Abstract: | After topical application of dinobuton or dinoseb to apple fruits approximately 75% and 72% respectively of the applied material was lost after 28 days. From apples treated with dinobuton the unchanged compound was the major component present up until 8 days but at later times the amounts of polar transformation products and water-soluble compounds predominated. Only small amounts of dinoseb were found at all times. A similar pattern of results was obtained from apples treated with dinoseb. The maximum amounts of material absorbed through the fruit skin were 3% from dinobuton-treated apples and 7% from dinoseb-treated applies. |
