FINISH™ (60 g cyclanilide + 480 g ethephon ai's per liter) has been tested for the promotion of earlier, concentrated boll opening and defoliation over the past four years in all major cotton growing countries. More than a hundred trials were laid out outside of the United States in a broad variety of conditions. The results obtained show that FINISH™, at equivalent ai. rates ensured as good or often better boll opening than PREP^®; and as good or often better defoliation than the best defoliants (Merphos, Thidiazuron) whether these were used alone or in tank mixture with Prep^®;. FINISH™ also provided a good inhibition of juvenile regrowth and its boll opening/defoliant efficacy was only slightly decreased at lower temperatures.

Typical examples from the mentioned trial work are presented in this paper.
