White bean tolerance and weed control were examined by applying halosulfuron alone or in combination with pendimethalin, dimethenamid-P, orS-metolachlor applied PRE. All herbicides applied alone or in combination caused less than 3% visible injury 1 and 4 wk after emergence (WAE). Halosulfuron applied PRE provided greater than 95% control of common lambsquarters, wild mustard, redroot pigweed, and common ragweed and less than 55% control of green foxtail at 4 and 8 WAE. Weed density and dry weight at 8 WAE paralleled the control ratings. Dry bean yields in halosulfuron plus a soil applied grass herbicide did not differ compared to the weed-free control. Green foxtail competition with halosulfuron PRE applied alone resulted in reduced white bean yield compared to the weed-free control.

“…However, the interactions between the herbicides in a mixture may vary with the active ingredient, the weed species, and even the rate of the respective herbicides in a mixture. For example, synergistic interactions have been reported with 2,4-D plus halosulfuron for common lambsquarters control ( Isaacs et al, 2006 ), and mesotrione plus glufosinate for common ragweed ( Ambrosia artemisiifolia L.) and giant foxtail ( Setaria faberi Herrm.) control ( Armel et al, 2008 ).…”

Glyphosate-resistant (GR) giant ragweed is a problematic broadleaf weed in crops including maize and soybean in the Midwestern United States. Commercialization of crops with 2,4-D or dicamba and glufosinate resistance will allow post-emergence (POST) applications of these herbicides. Therefore, information is needed on how 2,4-D/dicamba will interact with glufosinate in various rate combinations. The objectives of this study were to evaluate the interaction of glufosinate plus 2,4-D and/or dicamba for control of GR giant ragweed, and to determine their effect on GR giant ragweed density, biomass, maize injury, and yield. Field experiments were conducted in 2013 and 2014 in a field infested with GR giant ragweed in Nebraska, United States. The treatments included POST applications of glufosinate (450 or 590 g ai ha-1), 2,4-D, or dicamba at 280 or 560 g ae ha-1 applied alone and in tank-mixtures in glufosinate-resistant maize. The results showed that dicamba applied alone resulted in 56 to 62% and 73 to 83% control at 14 and 28 days after treatment (DAT), respectively, and ≥95% control at 60 DAT or at harvest compared to 17 to 30% and 57 to 73% control with 2,4-D applied alone at 280 and 560 g ai ha-1, respectively. Glufosinate tank-mixed with 2,4-D and/or dicamba consistently provided ≥89% control of GR giant ragweed, except that control with glufosinate plus 2,4-D varied from 80 to 92% at 60 DAT and at harvest. The comparison between the observed and expected control (determined by Colby’s equation) suggested an additive interaction between glufosinate and 2,4-D or dicamba for control of GR giant ragweed. Contrast analysis also indicated that GR giant ragweed control with glufosinate plus 2,4-D or dicamba was either consistently higher or comparable with individual herbicides excluding 2,4-D applied alone. Herbicide programs, excluding 2,4-D at 280 g ae ha-1, resulted in ≥80% reduction in GR giant ragweed density. Tank-mixing glufosinate with 2,4-D or dicamba showed an additive effect and will be an additional tool with two effective modes of action for the management of GR giant ragweed in maize.

“…Yield d 0.59 kg ha À1 glufosinate, and better control of common cocklebur than any rate of glufosinate. Many researchers have found that herbicides applied in combination can provide better control than applications of those herbicides alone (Hillger et al 2009;Isaacs et al 2006;Gonzini et al 1999). When glufosinate and 2,4-D combinations were applied to 15-cm plants, all rates of 2,4-D improved the control of common waterhemp compared to applications of glufosinate alone at 0.45 and 0.59 kg ha À1 (Table 6).…”

The introduction of transgenic crops with resistance to 2,4-D will provide growers with new weed management options in soybean. Field and greenhouse experiments were conducted in 2010 and 2011 to determine the influence of weed height on compatibility of glufosinate and 2,4-D in resistant soybean. Results from these experiments indicate a significant increase in the rate of glufosinate or 2,4-D is needed when applied alone in order to achieve similar levels of weed control as lower rates of glufosinate and 2,4-D combinations. Mixtures of glufosinate and 2,4-D were more effective in controlling common waterhemp, Asiatic dayflower, and barnyardgrass than either herbicide alone, and with the magnitude of difference greater as the height of common waterhemp increased. Large crabgrass control decreased when glufosinate was applied with 2,4-D compared with glufosinate alone, with the magnitude of the reduction greater as weed height increased. Sequential application of glufosinate and 2,4-D eliminated the antagonism noted with tank mixtures. Soybean yields were also reduced by approximately 3% in response to 30 to 35–cm compared to 10 to 15–cm herbicide applications because of the combination of weed interference and reduced control. Overall, results from these experiments indicate that glufosinate plus 2,4-D combinations are likely to provide increased control of problematic weeds like Asiatic dayflower and common waterhemp while providing similar grass control as herbicide programs that contain glufosinate alone.
