PRODUCT INTRODUCTION
description
Tribufos is a colorless to pale yellow liquid with a skunk-like odor; it is used only as a defoliant (a chemical that removes leaves) for cotton plants. Removing the leaves keeps certain pests that may be found on the leaves from damaging the cotton before it is picked.
