Abstract

Benzoylprop-ethyl (ethyl-N-benzoyl-N (3,4-dichlorophenyl)-2-amino-propionate) at 1.1 to 5.5 kg/ha gave good control of wild oats (Avena fatua L.) resulting in significantly higher yields of wheat (Triticum aestivum L. cv. Manitou and Neepawa). Late herbicide application (4-leaf growth stage of wild oats) provided better wild oat control and slightly better wheat yields than early application (1.5-leaf stage) in 1969 but not in 1970. Of the three herbicide formulations evaluated, the FX 2182 liquid formulation gave slightly higher wheat yields. Benzoylprop-ethyl at 1.4 kg/ha in mixture with TCA (sodium salt of trichloroacetic acid) at 0.56 kg/ha was less effective in controlling wild oats than benzoylprop-ethyl alone, but wheat yields were unaffected. However, addition of the amine salt of 2,4-D ((2,4-dichlorophenoxy) acetic acid) or MCPA ([(4-chloro-o-tolyl) oxy] acetic acid) at 0.56 kg/ha to benzoylprop-ethyl/TCA mixtures significantly reduced the efficiency of benzoylprop-ethyl for wild oat control and reduced wheat tolerance resulting in lower yields.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
