“…multiflorum (Lam.) Husnot], and perennial ryegrass ( Lolium perenne L.) (Jalaludin et al, 2017). Thus, over-reliance on 2,4-D, glufosinate, or dicamba should be avoided and a diversity of herbicide chemistries must be maintained by using herbicide tank-mixtures with multiple effective modes of action, along with non-chemical weed control methods including crop rotation, tillage, competitive cultivars, weed seed destruction, and cover crops, among others (Norsworthy et al, 2012).…”

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.

“…Unlike imazamox, the absorption and translocation patterns of 14 C‐glufosinate were lower, because this herbicide has low or no mobility due to its rapid phytotoxicity in the source leaf tissue . This explain the low amounts of glufosinate absorbed and translocated in the R and S wheat plants.…”

Glutamine synthetase is a key enzyme that exists in every living organism. It is responsible for incorporating ammonium into glutamate, generating glutamine. Research on this enzyme has grown substantially over the last decades. The recent advances in the determination of its structure, through the crystallization of novel classes of glutamine synthetase with increased resolution, greatly contributed to a shift in the glutamine synthetase research from fundamental to more applied. Here, we explore the active sites of glutamine synthetases, review the structural and catalytic roles of their active sites' ions Mg 2+ s, combine the information gathered from recent computational studies dedicated to unravel their catalytic mechanisms with the hypothesis raised at the beginning of the XXI century based on experimental studies, glance at the development of competitive glutamine synthetase inhibitors, and highlight the high value of these enzymes to industry, namely in the fields of agriculture and medicine.
