MacDonald , Rebecca L. Articles by Syvertsen, J. Effects of fungicide and adjuvant sprays on nesting behavior in two managed solitary bees, Osmia lignaria and Megachile rotundata. Pestic Sci 38 2—3: Characterization of trisiloxane surfactants from agrochemical adjuvants and pollinator-related matrices using liquid chromatography coupled to mass spectrometry.
Spray Adjuvants and Surfactants
Paraquat and glyphosate, representing contact and translocated herbicides, respectively, provided similar grass species control for all nozzle types, regardless of spray volume. January applications were also included since their foliar residues may pose toxicity risks for newly arriving bee colonies. Amine Garlon 3A formulations of triclopyr combined with Silwet , and the commercial triclopyr ester formulation, Garlon 4, were applied using a Radiarc sprayer equipped with 0. Macrostructure forming surfactants useful as spray drift control agent in pesticide spraying applications Jinxia Susan Sun, Akzo Nobel. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Published online May Basic principles of selection of adjuvants Tharwat Tadros, Independent Consultant. Organosilicone surfactants are good stand alone pesticides, toxic to bees, and are also present in drug and personal care products, particularly shampoos, and thus represent an important component of the chemical landscape to which pollinators and humans are exposed. Biochemical effects of nonylphenol polyethoxylate adjuvant, Diquat herbicide and their mixture on the three-spined stickleback Gasterosteus aculeatus L. The most common adjuvant is a surfactant. Whereas increasing product concentration improves adhesion, the lowest contact phytotoxicity result would be from lowering product concentration.
Droplet spectra and wind tunnel evaluations of air-induction and pre-orifice nozzles. To take full advantage of the properties of organosilicones, the antagonistic co-formulants of Garlon 3A needed to be removed or replaced, the best surfactant formulation identified, and a cost-effective concentration of the surfactant s needed to be found. Foam Cutter reduces waste from pesticide spillage and saves tank fill-up time. Aircover Nonionic Organosilicone Surfactant, Winfield. Ironically, increasing fungicide load in pollen has been associated with increased probability of fungal Nosema infection in exposed bees Chromobacterium subtsugae strain PRAA - The adhesion and retention studies also evaluated the influence of leaf angle.
