Weed Science, 1988
Greenhouse studies were conducted to determine the influence of glyphosate [N-(phosphonomethyl)glycine] and surfactant concentration on Canada thistle [Cirsium arvense(L.) Scop. # CIRAR] control. Five, 10, and 30% (v/v) solutions of the commercial formulation of glyphosate (356 g ae/L glyphosate and 178 g ai/L MON 0818) applied in 2-μl droplets to ...

Annals of Applied Biology, 1985
SUMMARYFlax cv. Hera was grown in pots at a density of 2000 plants/m2. At various stages of maturity plants were either sprayed with glyphosate (Roundup, Monsanto plc) at a rate equivalent to 1.4 kg a.e./ha or the uppermost leaves of the main stem were treated with 14C‐glyphosate. Uniform desiccation to greater than 80% DM within 5 wk was obtained with

Influence of glyphosate on uptake and translocation of calcium ion in soybean seedlings
Weed Research, 1983SummaryCalcium ion in hydroponic solution with glyphosate [N‐phosphonomethyl (glycine)] did not significantly influence the efficacy of the herbicide in reducing growth of soybean (Glycine max) seedlings. Data from atomic absorption spectroscopy studies revealed that glyphosate reduced Ca2+ uptake and translocation, whether supplied alone or with other

Glyphosate efficacy, absorption, and translocation in pitted morningglory (Ipomoea lacunosa)
Weed Science, 2005Abstract Greenhouse and laboratory studies were conducted to examine the effects of site of plant exposure to glyphosate spray on efficacy, absorption, and translocation in pitted morningglory. Absorption of 14C-glyphosate in four-leaf pitted morningglory gradually increased with time from 19% at 1 h after treatment (HAT) to 44% at 192 HAT.

Droplet size affects glyphosate retention, absorption, and translocation in corn
Weed Science, 2003Abstract The effect of droplet size on retention, absorption, and translocation of 14C-glyphosate was studied in glyphosate-resistant corn. Fine, medium, and coarse spray droplets were studied using a track-sprayer equipped with commercially available nozzles.

Glyphosate herbicide was applied to red maple, sweetgum, and loblolly pine seedlings at the end of the second growing season to evaluate the effects of application timing and water stress on glyphosate absorption, translocation, and efficacy.

Penetration, Translocation, and Toxicity of Glyphosate in Bermudagrass (Cynodon dactylon)
Weed Science, 1977A 3.6 g/L solution of glyphosate [N-(phosphonomethyl)glycine] applied to selected parts of bermudagrass [Cynodon dactylon (L.) Pers.] shoots did not kill the entire plant. However, phototoxicity increased as more parts of the plant were treated. No differences were observed when solutions of 3.6 and 5.4 g/L glyphosate were applied at 94 and 373 L/ha ...

Translocation and Absorption of Glyphosate in Flowering Sicklepod (Senna obtusifolia)
Weed Science, 2008Sicklepod is a competitive and prolific weed that emerges throughout the crop season. Glyphosate applications to flowering sicklepod greatly reduce seed production, but there is limited information on glyphosate translocation in flowering weeds. Therefore, a laboratory study was conducted to document the absorption and translocation of14C-glyhosate in ...
