“…Horseweed counts from sunrise applications (34%) were not different from sunset or midday applications (4% and 75%, respectively); however, sunset applications were more efficacious than applications at midday. Although the majority of application TOD research has indicated that POST herbicide control is generally greater when the herbicide is applied in the middle portion of the day (Doran and Andersen 1976; Martinson et al 2002; Miller et al 2003; Peterson and Al-Khatib 1999; Stewart et al 2009; Stopps et al 2013), some research suggests that this conclusion may not be accurate for all herbicides (Fadayomi and Warren 1977; Lee and Oliver 1982; William and Warren 1975). William and Warren (1975) found that nitrofen was more efficacious on purple nutsedge ( Cyperus rotundus L.) when applied at night rather than during the day, and Fadayomi and Warren (1977) later determined that this increase in efficacy resulted from an increase in herbicide absorption.…”

Effect of Time of Day of Application of 2,4-D, Dicamba, Glufosinate, Paraquat, and Saflufenacil on Horseweed (Conyza canadensis) Control

A study to evaluate the effect of application time of day (TOD) on the efficacy of five burndown herbicides was conducted in Alabama and Tennessee. Treatments of 2,4-D, dicamba, glufosinate, paraquat, and saflufenacil were applied at sunrise, midday, or sunset to a native population of horseweed and analyzed separately. Control of glyphosate-resistant (GR) horseweed with 2,4-D, dicamba, glufosinate, and saflufenacil was greatest from the midday application. Percentage of living horseweed counts for all of these herbicides followed a similar pattern. Control from paraquat was lowest at the midday timing and greatest from the sunset application with surviving horseweed plant populations reflecting those control ratings. Application TOD significantly affected all of the herbicides in this research. Applications of 2,4-D, dicamba, glufosinate, and saflufenacil are more efficacious when applied during the middle portion of the day, while paraquat is more efficacious when applied at sunset for maximum horseweed control.

“…Oxyfluorfen reduces the content of chloroplasts in the cells of the assimilation parenchyma of leaves, and this has an adverse effect on the biochemical and physiological processes in plants (2,4,7,8,9,16,17). The photosynthesis, transpiration, and gas exchange disruptions are expressed in delayed plant growth and development, and frequently, this is a contributing factor to plant death (1,3,5,6,10,11,12,13,14,15,17).…”

“…Protox-inhibiting herbicides are absorbed by root (soil-applied) and leaf tissue (foliar-applied), but have limited translocation (Fadayomi and Warren 1977;Ritter and Coble 1981a;Unland et al 1999). Ritter and Coble (1981b) showed that translocation of acifluorfen is also dependent on temperature and relative humidity.…”

Rapid Assay Evaluation of Plant Response to Protoporphyrinogen Oxidase (Protox)-Inhibiting Herbicides

Protoporphyrinogen oxidase (protox)-inhibiting herbicides damage cell membranes, resulting in electrolyte leakage. A whole-plant dose-response study and a rapid assay that measured electrolyte leakage was used to determine the response of wild mustard, soybean, and protox inhibitor–susceptible and protox inhibitor–resistant common waterhemp to increasing doses of three protox inhibitors: acifluorfen, fomesafen, and sulfentrazone. For the dose-response study, whole plants were treated with the three protox-inhibitor herbicides. Electroconductivity assay 1 consisted of cutting discs from leaf tissue and submerging them in an incubation medium containing concentrations of acifluorfen, fomesafen, or sulfentrazone. In electroconductivity assay 2, the entire leaf was treated with solutions containing acifluorfen, fomesafen, or sulfentrazone. The whole-plant dose-response study showed increasing visible injury with increasing herbicide rates for all species and all herbicides. The order of visible injury was wild mustard > susceptible common waterhemp > resistant common waterhemp > soybean. In assay 1, electrolyte leakage from leaf discs treated with acifluorfen or fomesafen increased with increasing herbicide concentrations, and was similar for all species. In contrast, electrolyte leakage from leaf discs treated with sulfentrazone did not increase with increasing herbicide concentrations for any species. In assay 2, only wild mustard leaf discs increased in electrolyte leakage with increasing herbicide rates of acifluorfen, fomesafen, and sulfentrazone and followed the regression curves established by the whole-plant dose-response study. However, assay 2 was not able to distinguish between susceptible wild mustard and tolerant soybean, or between susceptible and resistant waterhemp.
