Abstract

There was no antagonism between dalapon (2,2-dichloropropionic acid) or TCA (trichloroacetic acid) and BAS 9052 {2 - [1 -(ethoxyimino)butyl] - 5 - [2 -(ethylthio) -propyl] -3-hydroxy-2-cyclohexen-1-one} at 0.3 kg/ha for control of volunteer barley (Hordeum vulgare L. ‘Bonanza’) and wheat (Triticum aestivum L. ‘Neepawa’) in flax (Linum usitatissimum L. ‘Dufferin’). However, MCPA {[(4-chloro-o - tolyl)oxy] acetic acid} amine at 0.2 to 0.6 kg/ha had an antagonistic effect on BAS 9052, especially at 0.1 kg/ha, for control of wild oat (Avena fatua L.). BAS 9052 at 0.3 kg/ha overcame this antagonistic effect of MCPA. Field results confirmed that wild oat control with BAS 9052 at 0.3 kg/ha was not reduced by the mixtures with each of four broadleaf weed herbicides at 0.6 kg/ha. The mixtures gave excellent control of grass and broadleaf weeds. Flax seed yields were five times that of the unsprayed check and were equal to the yield of the handweeded treatment.
