“…The rate of uptake was slower in sensitive field bean than in wild oat (Avena fatua L.) (Holloway and Edgerton 1992). In contrast, tolerant oat (Avena sativa L.) had faster uptake than sensitive soybean but levels were equal by 24 h after application (Hall et al 1982). Similar uptake levels were observed between tomato (Solanum lycopersicum Mill.)…”

Since its discovery and initial commercialization in the 1940s, 2,4-D has been an important tool for weed control in a wide variety of crop and noncrop uses. Work studying its chemistry, physiology, mode of action, toxicology, environmental behavior, and efficacy has not only helped elucidate the characteristics of 2,4-D but also provided basic methods that have been used to investigate the properties of hundreds of herbicides that followed it. Much of the information published by researchers over 60 yr ago is still pertinent to understanding the performance of 2,4-D today. Further, new studies continue to be published, especially regarding the mechanisms of 2,4-D action at the molecular level. New uses for 2,4-D, sometimes enabled by biotechnology, continue to be developed. This review strives to provide an overall understanding of 2,4-D activity in plants, plant sensitivity to 2,4-D, toxicological impacts, and current and future uses.

“…Olson and Nalewaja (1982) studied the effect of MCPA on 14 C‐diclofop methyl uptake and translocation and found that the antagonistic effect of MCPA reduced diclofop‐methyl uptake, de‐esterification, and translocation. However, there are other studies that showed no antagonism between these two herbicides (Hall et al . 1982; Kelly & Chapman 1995).…”

Field and greenhouse experiments were conducted in 2004 and 2005 to study weed control and the response of winter wheat to tank mixtures of 2,4-D plus MCPA with clodinafop propargyl. The field experiments were conducted at Yazd and Oroumieh, Iran, with factorial combinations of 2,4-D plus MCPA at 0, 975, and 1300 g ai ha -1 and with clodinafop propargyl at 0, 64, 80, 96, and 112 g ai ha -1 in four replications. The greenhouse experiments further evaluated the effect of these tank mixtures on weed control, where each herbicide mixture was considered as one treatment and the experiment was established in a randomized complete block design with four replications. In the field experiments, the herbicides were applied at wheat tillering, while in the greenhouse experiments they were applied at the beginning of the tillering stage and at the four-leaf stage of the grass and broadleaf weeds, respectively.The results indicated antagonistic effects between 2,4-D plus MCPA and clodinafop propargyl. The best tank mixture with regard to weed control efficacy was 2,4-D plus MCPA at 975 g ai ha -1 with clodinafop propargyl at 96 g ai ha -1 . The wheat grain yield was also increased by the tank mixture of clodinafop propargyl with 2,4-D plus MCPA. Generally, to inhibit clodinafop propargyl efficacy reduction due to tank-mixing with 2,4-D plus MCPA, it is recommended that the application dose of 64 g ai ha -1 should be increased to 96 g ai ha -1 .

“…There are reports that the chlorophenoxy herbicides 2,4-D and MCPA cause decreased uptake, de-esterification and/or translocation of diclofop-methyl and it has been proposed that one or a combination of these effects is the cause of antagonism (Qureshi & Vanden Born, 1979;Olson & Nalewaja, 1982). However, there are also reports that these processes are unaffected by chlorophenoxy herbicides (Hall, Edgington & Switzer. 1982b;Hill, Todd & Stobbe, 1980;Kafiz et al, 1989).…”

“…It has been proposed that chlorophenoxyherbicides such as 2,4-D and MCPA and the benzoic herbicide dicamba cause antagonism of diclofop-methyl activity due to their auxin-like properties (Shimabukuro etal., 1978;Hall et al, 1982b;Shimabukuro, Hoerauf & Walsh, 1986;Fitzsimons, Barnwell & Cobb, 1988). There is good evidence that auxin-induced growth is in part mediated through H* efflux into cell walls (Taiz, 1984).…”

Summary: Avena saliva cv. Amuri and A. fatua were sprayed with diclofop methyl (1.0 kg a.i. ha−1) alone and in combination with 2,4‐D (1.1 kg a.i. ha−1), bentazone (1.0 kg a.i. ha−1), chlorsulfuron (15 g a.i. ha−1) or dicamba (0.3 kg a.i. ha−1). Effects of the herbicides on leaf extension rate during the first 8 to 10 days after spraying and subsequent growth (dry weight) after 57–75 days were determined by comparison with unsprayed plants. Diclofop‐methyl applied alone did not cause a decrease in leaf extension rate of A. saliva or A. fatua until at least 4 days after spraying. All broadleaf weed herbicides in combination with diclofop‐methyl caused a decrease in leaf extension rate of both species within 2 days of spraying. Ten days after spraying, leaf extension rates for plants sprayed with a broadleaf weed herbicide plus diclofopmethyl (all combinations) were lower than for unsprayed plants but greater than for plants sprayed with diclofop‐methyl alone. With the exception of A. fatua sprayed with bentazone, long‐term growth of plants sprayed with a broadleaf weed herbicide plus diclofop‐methyl (all combinations) was lower than for unsprayed plants but greater than for plants sprayed with diclofop‐methyl alone. Bentazone applied with diclofop‐methyl caused a substantial decrease in leaf extension rate of A. fatua within 24 h of spraying but at harvest, dry weight of plants from this treatment was similar to or less than that for plants sprayed with diclofop‐methyl alone. Application of diclofop‐methyl with bentazone at a rate of 0.3 kg a.i. ha−1 also caused a reduction in leaf extension rate of A. fatua within one day of spraying. At this rate of bentazone, dry weight of plants at harvest was intermediate to that of unsprayed plants and those sprayed with diclofop‐methyl alone. It is proposed that decreased leaf expansion rate during the first few days afte spraying is the cause of broadleaf weed herbicide antagonism of diclofop‐methyl.
