...Richard K. Zollinger; Mark L. Bernards; Dallas E. Peterson; Bryan G. Young; Gregory K. Dahl; Joe V. Gednalski Glyphosate is a weak acid herbicide and can bind with antagonistic salts in the spray carrier. Diammonium sulfate (AMS) is commonly used as an adjuvant with glyphosate to enhance activity...

KEYWORDS: adjuvant, spray drift, drift reduction, drift control, aerosol particle size, glyphosate Introduction Regulatory bodies have become increasingly concerned with the movement...

...Richard K. Zollinger; John D. Nalewaja; Dallas E. Peterson; Bryan G. Young Glyphosate is a weak acid herbicide and can bind with calcium in the spray carrier. Diammonium sulfate is commonly used as an adjuvant with glyphosate to enhance phytotoxicity and overcome antagonistic effect...

...Dallas E. Peterson; Curtis R. Thompson Glyphosate herbicide labels generally recommend addition of ammonium sulfate (AMS) to the spray solution, which often improves weed control, especially when mixed with hard water. AMS in solution disassociates, and the sulfate binds with cations in the spray...

...Gregory Volgas; Robert E. Mack; Johnnie Roberts; Mark Wayland; Bobby Alford Glyphosate is a broad-spectrum herbicide effective on deep-rooted perennial species and on annual and biennial species of grasses, sedges, and broadleaf weeds. The solubility of glyphosate acid is relatively low in water...

...H. de Ruiter; B. Mack; R. van der Schoor; H. Jalink Fluorescence can be used to measure and visualize the activity of herbicides that inhibit the photosynthesis. Glyphosate, although not acting primarily on the photosystems, appears to increase fluorescence of plants. We investigated whether...

...Curtis M. Elsik; Howard M. Stridde; R. Scott Tann The development of many crops with glyphosate tolerance has created a large demand for glyphosate herbicide formulations. Commercial aqueous solution glyphosate formulations usually contain a surfactant along with other formulation additives...

..., especially glyphosate. With the advent of glyphosate-tolerant crops, glyphosate has become almost universal in its use. This has led to some issues with weeds hard to control with glyphosate alone. Recently a practice has developed where other herbicides and COC formulations are mixed with glyphosate...

...PM McMullan; S Thurman; G McManic; M Brigance A series of adjuvants were developed to improve herbicide performance when applied through air induction nozzles. A series of research trials were conducted in 2004 and 2005 with clethodim, foramsulfuron, and glyphosate. Efficacy of these herbicides...

...RA Downer; JK Hacker; RS Ebert Tests were conducted with a widely used herbicide (glyphosate) that is available in a range of formulations and a selection of commonly used nozzle types [XR TeeJet, extended range flat spray tip (XR), Turbo TeeJet, wide angle flat spray tip (TT), AI TeeJet, Air...

...CM Elsik; HM Stridde N-phosphonomethylglycine (glyphosate) is firmly established as the preeminent herbicide of choice in a wide range of applications for the crop protection industry. It is well known that the efficacy of glyphosate can be enhanced with the use of surfactant adjuvants. Surfactants...

...Y Lei Ether amines, ether amine alkoxylates, and their derivatives have found increased use as agricultural surfactants in the past decade. Most of the documented applications of ether amine surfactants have been limited to glyphosate formulations, where ether amine ethoxylates, oxides, and quats...

... of glyphosate was antagonistic to Select and V-10137, but V-10137 overcame most of the antagonism. These results suggest V-10137 activity is greater than commercial clethodim formulations of Select or Arrow, may not require additional oil adjuvant for grass control, is effective with glyphosate, and can...

...S Singh; M Singh Glyphosate is the most common non-selective post-emergence herbicide used under diverse conditions. The efficacy of foliar applied herbicides is greatly influenced by adjuvants, but not all adjuvants have a synergistic effect. Greenhouse experiments were conducted using weed...

...BG Young; JM Young Glyphosate was applied alone and with either ammonium sulfate (AMS) or RUSA 703 (a premix of hydroxypropyl guar and AMS). Herbicide treatments were applied at 3-h intervals starting at 6:00 am and ending at 9:00 pm. The efficacy of glyphosate was dependent on the application time...
