Abstract
A new formulation of clethodim {(E,E)‐(±)‐2‐(1‐[([3‐chloro‐2‐propenyl]oxy)imino]propyl)‐5‐(2‐[ethylthio]propyl)‐3‐hydroxy‐2‐cyclohexen‐1‐one} is labeled for the control of grasses and volunteer grass crops, including glyphosate‐resistant corn. The effects of the formulation (new: 0.12 kg L −1 and current: 0.24 kg L −1 ) and adjuvants (ammonium sulfate [AMS], crop oil concentrate [COC] or both) on the absorption and translocation of the 14 C‐clethodim was determined at 1, 4, 12, 24, 48, and 72 h after treatment (HAT) in wheat under greenhouse conditions. The absorption of the 14 C‐clethodim with the 0.12 kg L −1 formulation was higher than that with the 0.24 kg L −1 formulation, especially at 24 HAT and beyond, regardless of the presence or absence of an adjuvant. The addition of an adjuvant increased the absorption of the 14 C‐clethodim with the 0.12 kg L −1 formulation at all harvest times, except at 72 HAT. However, there were no differences in the 14 C‐clethodim absorption among the adjuvants added to the 0.12 kg L −1 formulation, except at 48 and 72 HAT. Most of the 14 C‐clethodim remained in the treated leaf independent of the formulation or adjuvant. The formulation did not have an impact on the distribution of the absorbed 14 C‐clethodim; however, the presence of an adjuvant increased the movement of the 14 C‐clethodim out of the treated leaf. Most of the absorbed 14 C‐clethodim remained in the treated leaf and a negligible amount translocated to the root. These results demonstrated the improved absorption of clethodim with a formulation containing half of the active ingredient (0.12 kg L −1 ) and the inclusion of both AMS and COC.
