SANCHEZ, P et al. Eficacia de haloxifop-r-metil con distintos coadyuvantes. FAVE. Secc. Cienc. agrar. [online]. 2018, vol.17, n.2, pp.63-69. ISSN 1666-7719.

In Argentina, thirteen biotypes of glyphosate-resistant weeds have been confirmed, eight of these are grasses. To control grassy weeds herbicides such as haloxifop-R-methyl with the addition of mineral oil is recommended. Other additives to replace the mineral oil are currently offered in the market with equal or greater efficacy and lower costs. The aim of this work was to evaluate the efficacy of haloxifop-R-methyl with different adjuvants (mineral oils, ethoxylated nonylphenol, methyl esters of vegetable oil, ethoxylated linear alcohol and oxo polyoxyethylenated alcohol), applied in oats 40 days after sowing. Efficacy was determined by senescence and dry weight of the plants. The best herbicide action of haloxifop-R-methyl was with the use of mineral oil as an additive.
