Current Issue April , 53 4. Transmission electron micrograph of stomata of mature grapefruit peel in cross-sectional view showing cuticle C , epidermal cells EP , stomatal pore SP , substomatal cavity SC , and fungal hyphae FH. Although Cu fungicides are not routinely mixed with silicone surfactants or urea in spray tank mixes, the behavior of Cu fungicides with and without such adjuvants could lead to insights about potential mechanisms of Cu phytotoxicity. Characterization of the spray droplet spectra and patterns of four venturi-type drift reduction nozzles. Effect of protective shields on drift and deposition characteristics of field sprayers.

Published online May The concentration of urea was equivalent to 7. Usually, adjuvants are much less expensive than formulated active ingredients and can reduce the active ingredient dose needed by an order or more of magnitude 3 , 4. Dramatic impacts of agrochemical formulants on the bee toxicity of pesticide active ingredients have been documented Helena has representatives located across the country to serve you. Synergy is designed for use with those pesticides or products whose labels recommend the addition of a methylated seed oil, crop oil concentrate, or nonionic spray adjuvant to improve coverage and penetration.

Co-occurring and synonymous records were assumed to represent combined pesticide and adjuvant products within the same tank application mix. Although Cu fungicides are not routinely mixed with silicone surfactants or urea in spray tank mixes, the behavior of Cu fungicides with and without such adjuvants could lead to insights about potential mechanisms of Cu phytotoxicity. Commercial formulations of fumagillin acid used to control Nosema and other microsporidian fungal diseases in honey bees and mammals, respectively, are actually salts of the base dicyclohexylamine.

Environ Sci Technol 48 Organosilicone surfactants can reduce the surface tension of aqueous pesticides far below that which is possible with nonsilicone surfactants, resulting in efficient wetting of even the most hydrophobic leaf surfaces. Improving water soluble agricultural formulations with amine oxides Andrew Malec, Stepan. The Leaf Surface of Major Weeds. The non-ionic spray adjuvant R synergized the acute toxicity of the insecticides spinosad 19 and imidacloprid 20 on aquatic crustaceans and, in the absence of an insecticide, reduced the growth rate of Daphnia pulex at relevant field concentrations found after application near aquatic systems
