Fluorine Substitution Affects Decarboxylation of 2,4-Dichlorophenoxyacetic Acid in Apple.
Marked differences exist in the rate at which 2,4-dichlorophenoxyacetic acid (2,4-D) is broken down by different plant species and varieties. This activity has been measured by collecting carbon dioxide from leaves treated with carboxyl-C(14) labeled compounds. The substitution of fluorine for chlorine in the 4-position of 2,4-D inhibits this decarboxylation in leaves which are able to break down 2,4-D rapidly.
