Abstract

Absorption of 14C-bentazon from the leaf surfaces of common cocklebur and velvetleaf was rapid and most occurred within 4 h after foliar application. Greater 14C in the epicuticular wax (ECW) did not correlate with higher radioactivity in the leaf tissue. There was significantly less ECW on the “mature” leaves of common cocklebur and “juvenile” leaves of velvetleaf. However, the “mature” leaves exhibited greater 14C absorption for both species. The use of 28% urea ammonium nitrate increased 14C-absorption when compared with crop oil concentrate and with no adjuvant.
