To evaluate residual control of common sowthistle in fallow
In this situation all treatments containing Valor (alone or in mixture), Voraxor, Tordon 75-D, Terbyne Xtreme and an experimental Group 14 herbicide all provided good levels of residual common sowthistle control (90-100%), up to ~55 days after application with ~290 mm of rainfall.
Valor, and the experimental Group 14 herbicide provided longer residual control under the high rainfall conditions but did not effectively control an emergence that occurred ~80 days after application following >330 mm of rainfall. Balance and Dual Gold provided poor levels of weed suppression under the high rainfall conditions.
