Literature information indicates that Silwet® L‐77 acted as a rainfastening adjuvant and provided increased herbicidal activity on quackgrass. However, previous results on trembling aspen were inconclusive, probably due to the high dosage rate (1.

A fluorometric method to determine rainfastness, volatilization and photostability of glyphosate from glass slides, after application of vision® with two adjuvants

Autor: J. W. Leung

Publikováno v: Journal of Environmental Science and Health, Part B. 29:341-363

A fluorometric method was developed to quantify glyphosate loss from glass surfaces after exposure to the natural forest environment. The method was based on the principle of converting glyphosate into glycine, followed by the fluorogenic labeling wi

Two commercial formulations of Bacillus thuringiensis var. kurstaki (BTK), Foray® 48B and Thuricide® 48LV, were applied aerially over nine spray blocks in a hardwood forest in West Virginia in 1991. Droplet spectra and spray mass deposits were dete

Effect of adjuvants on rainfastness and herbicidal activity of glyphosate deposits on trembling aspen foliage

Autor: Barrie G.R. Webster, J. W. Leung

Publikováno v: Journal of Environmental Science and Health, Part B. 29:1169-1201

Radiolabelled end‐use mixtures of glyphosate with and without a cationic surfactant (Ethomeen® T/25) and an organosilicone surfactant (Silwet® L‐77) were applied onto trembling aspen (Populus tremuloids Michx.) leaves at the rate of 1.0 kg of A
