“…Previous studies with mixtures of glyphosate and diverse groups of herbicides have revealed antagonism on annual and perennial weed species (Stahlman & Philips, 1979; O'Sullivan & O'Donovan, 1980a,b; Selleck & Baird, 1981). Joint action studies with sulfonylurea herbicides have involved phenoxyalkanoic acid herbicides (Mathiassen & Kudsk, 1993; Kudsk & Mathiassen, 1995; Hollaway et al. , 1996; Streibig et al.…”

The joint action of binary mixtures of the amino acid biosynthesis-inhibiting herbicides glyphosate, glufosinate-ammonium, metsulfuron-methyl and imazapyr was assessed in pot experiments applying the Additive Dose Model (ADM). Plants of Sinapis arvensis or S. alba were sprayed with seven doses of the herbicides alone and binary fixed-ratio mixtures of the four herbicides. In total, 73 binary mixtures were studied in six separate experiments. Mixtures of glyphosate and glufosinate-ammonium were less phytotoxic than predicted by ADM whether commercial formulations or technical grade products were applied. In contrast, mixtures of glyphosate and metsulfuron-methyl, glyphosate and imazapyr, glufosinate-ammonium and mets-ulfuron-methyl, glufosinate-ammonium and imazapyr, and metsulfuron-methyl and imazapyr either followed ADM or were synergistic. Synergism was observed most frequently for mixtures of glyphosate or glufosinateammonium with metsulfuron-methyl. Synergism was also more pronounced for commercial formulations of glyphosate and glufosinate-ammonium than for the corresponding technical grade formulations, implying that synergism was caused by the presence of the formulation constituents of the commercial glyphosate and glufosinate-ammonium formulations in the spray solution.

“…Strong antagonism has been demonstrated with mixtures of the dimethylamine salt of MCPA and chlorsulfuron or metsulfuron-methyl. 22 Kudsk and Mathiassen,17 however, found that mixtures of mecoprop ethylene glycol diester and tribenuron-methyl followed ADM and Hollaway et al 23 found synergistic e †ects with MCPA iso-octyl ester and sulfonylureas at and response levels. At level there ED 75 ED 90 ED 50 was a tendency for the observed values to show a somewhat similar pattern to the one observed in Fig.…”

: The assessment of mixture e †ects is usually done with isoboles which illustrate whether mixture e †ects are greater or smaller than would be expected on the basis of the individual activities of the herbicides. Under the assumption of similarity of response curves and by incorporating a function that can model the shape of isoboles, we can statistically test whether divergence from the Additive Dose Model (ADM) is signiÐcant. Two dose-response experiments with mixtures of either salt or ester formulations of MCPA and mecoprop-P and one experiment with tribenuron-methyl and mecoprop-P were analysed. Mixtures of tribenuron-methyl and a salt formulation of mecoprop-P showed antagonism. Mixtures of salt formulations of MCPA and mecoprop-P followed ADM, whilst ester formulations of the same compounds showed synergism. To get reliable estimates, the model requires mixture ratios covering the whole isobole 1998 SCI ( Pestic. Sci., 53, 21È28 (1998)

“…Besides, herbicide formulation can lead to increasing or decreasing efficacy of herbicides in a mixture rather than predicted by ADM. For example, Streibig, Kudsk and Jensen (1998) showed that mixing mecoprop-P potassium salt with MCPA dimethylamine salt made the mixture additive under the ADM, while mixing the same herbicides as esters made the mixtures synergistic under ADM. In another experiment, Hollaway, Hallam and Flynn (1996) found synergistic effects with MCPA isooctyl ester and metsulfuron-methyl at ED 75 and ED 90 response levels on oilseed rape [Brassica Table 5. Dose-response parameters of the log-logistic model for either the herbicides applied alone or fixed-ratio binary mixtures of foramsulfuron or nicosulfuron with 2,4-D plus MCPA on redroot pigweed and common lambsquarters at the 4-6-true leaf stage.…”

Interaction of binary mixture of the two sulfonylurea herbicides: foramsulfuron or nicosulfuron with 2,4-D + MCPA, was evaluated in greenhouse experiments during 2010 and 2011 applying the additive dose model. Plants of redroot pigweed, common lambsquarters, common purslane and black nightshade were sprayed with seven doses of herbicides alone and in binary fixed-ratio mixtures. In total, 35 binary mixtures were studied in 7 separate experiments at ED 90 response level. Results indicated that mixture of foramsulfuron + 2,4-D + MCPA was synergistic on redroot pigweed compared to additive interaction between nicosulfuron and 2,4-D + MCPA. Mixture of foramsulfuron + 2,4-D + MCPA was slightly antagonistic on common lambsquarters and an additive interaction was observed with both foramsulfuron and nicosulfuron + 2,4-D + MCPA on common purslane. Finally, the mixture of foramsulfuron or nicosulfuron + 2,4-D + MCPA on black nightshade was antagonistic especially in mixtures where the ratio of sulfonylurea herbicides was more than 2,4-D + MCPA. Totally, 2,4-D + MCPA in mixture with sulfonylurea herbicides especially foramsulfuron provided better control of redroot pigweed in comparison with herbicides applied alone and other herbicide mixtures on weeds.Abbreviations: 2,4-D + MCPA: ((2,4-Dichlorophenoxy) acetic acid plus (4-chloro-2-methylphenoxy) acetic acid); ADM: additive dose model; a.i.: active ingredient; ALS: acetolactate synthase; DAT: days after treatment; ED: effective dose; Foramsulfuron: (2-(N-((4,6-dimethoxypyrimidin-
