Characterizing the Response of gdhA Transformed Tobacco to Glufosinate
… allows an increase in ammonium assimilation. Glufosinate leads to plant death by the irreversible inhibition of glutamate synthetase (GS) leading to a disruption of subsequent GS-related processes resulting in elevated ammonium and disruption of photorespiration. Therefore, it was speculated …

Composite poly(dimethoxyaniline) electrochemical nanobiosensor for glufosinate and glyphosate herbicides
… for quantitative determination of the herbicides glufosinate, glyphosate and its metabolite aminomethylphosphonic acid (AMPA). Firstly, the nanostructured poly(2,5-dimethoxyaniline) (PDMA) materials were synthesized on gold electrode by the electrochemical "template"method using …

Efficacy of glufosinate and weed control in transformed corn and soybean
Glufosinate is a postemergence herbicide that inhibits the glutamine synthetase enzyme in plants, causing an accumulation of ammonia, inhibition of photosynthesis, and ultimately plant death. The use of this herbicide has been limited to no-tillage prior to planting or in noncrop areas. Recent …

Effects of simulated drift of glyphosate, imazethapyr, glufosinate, and imazamox to non-transgenic rice
… 70 g ai/ha of imazethapyr, 493 g ai/ha of glufosinate, and 44 g ai/ha of imazamox. Herbicides were applied to rice at the 1-tiller, panicle differentiation (PD), boot, and physiological maturity growth stages. Spray volume varied proportionally to herbicide dosage and was 15 L/ha for the …

Effect of Temperature and Chemical Additives on the Efficacy of the Herbicides Glufosinate and Glyphosate in Weed Management of Liberty-Link and Roundup-Ready Soybeans
… ® soybeans are resistant to the herbicide glufosinate, because of the incorporation of a gene encoding phosphinothricin acetyl-transferase (pat), which is able to detoxify glufosinate. Roundup-Ready ® soybeans are transformed with an altered, non-sensitive form of …

Trimethylation Enhancement using Diazomethane (TrEnDi) Enhances Mass Spectrometry-Based Analysis of Glufosinate and 3-(Methylphosphinico)propionic Acid in Complex Matrices
Glufosinate is the second most commonly used herbicide worldwide; it inhibits glutamine synthetase, which results in increased ammonia levels in plants and mammals. Due to their high polarity, low volatility, small size and lack of chromophores and fluorophores, glufosinate and its breakdown …

Factors governing zoysiagrass response to herbicides applied during spring green-up
… nonselective herbicides such as glyphosate and glufosinate to control winter annual weeds. Although this weed control strategy is common in bermudagrass (Cynodon spp.), it has been less adopted in zoysiagrass due to unexplainable turf injury. Many university extension publications recommend …

Avoiding Protoporphyrinogen Oxidase Inhibiting Herbicide Selection Pressure on Common Ragweed and Palmer amaranth in Soybean
… <74%, yet controlled Palmer amaranth >96%. Glufosinate applied POST controlled Palmer amaranth and common ragweed 74-100%, regardless of PRE treatment. Flumioxazin PRE followed by fomesafen POST controlled common ragweed well; however, several non-PPO herbicide treatments or programs with …

Control and Fecundity of Palmer Amaranth (Amaranthus palmeri) and Common Ragweed (Ambrosia artemisiifolia) from Soybean Herbicides Applied at Various Growth and Development Stages
… using one SOA (mesotrione, dicamba, 2,4-D, or glufosinate alone). Seed production of 5 to 10 cm Palmer amaranth and common ragweed was reduced greater than 76% by fomesafen, auxin (dicamba and 2,4-D), or glufosinate containing treatments. Some weeds survived and set seed even when treated at …

Red rice competition and control in cultivated rice
… competitiveness with red rice and how to utilize glufosinate- and imazethapyr-resistant rice in water-seeded rice to control red rice. In the interference study, CL 121, Cocodrie, Drew, and Jasmine were seeded to obtain 95, 190, and 290 plants/sq m. Red rice density was 0 or 20 red rice plants/sq …

THE INFLUENCE OF CARRIER WATER QUALITY, COAPPLIED FOLIAR FERTILIZER, AND WATER CONDITIONING ADJUVANT ON HERBICIDE EFFICACY
… dioxygenase (HPPD); or mesotrione, glufosinate, isoxaflutole (MGI) resistant soybeans are being developed which will allow the use of mesotrione herbicide. Gaining knowledge on effect of carrier water quality will help for optimizing spray solution for herbicide application on …

Herbicide strategies for Palmer amaranth (Amaranthus palmeri) management in Illinois
… soybean. Single or multiple applications of glufosinate, or glufosinate plus residual herbicides were compared in Chapter 5 to determine the overall control of biomass and emergence of Palmer amaranth in glufosinate-resistant soybean. Results indicate that Palmer amaranth biomass reduction is …

New Herbicide Strategies for Weed Management in Pumpkin and Soybean and Potato Vine Desiccation
… set, and regulates tuber size. Saflufenacil, glufosinate, saflufenacil plus glufosinate, and carfentrazone plus glufosinate were compared to diquat applied at 43, 31, and 17% B potatoes; similar vine desiccation (14 days after treatment), skin set, and yield were noted amongst treatments. …

Herbicide resistant weeds in Missouri : sources and solutions
… the recommended field use rate of glyphosate, glufosinate, 2,4-D, dicamba, and cloransulam was applied to each population in order to determine the frequency and distribution of herbicide resistances in Missouri horseweed. A population was classified as resistant if visual control 28 days after …

Control of two perennial grasses in southern turfgrasses
… control. In nonselective studies, glyphosate, glufosinate, and sulfosate were evaluated at equivalent rates (1.12, 2.24, or 4.48 kg ha-1). At 7 WAT, knotgrass control was at 99% for glufosinate, regardless of rate applied. All rates glyphosate and glufosinate or sulfosate applied at 2.24 and …
