Capacidad de retención y depósito de fitosanitarios sobre la superficie de manzanas (Malus doméstica Brokh) = Retention capacity and phytosanitary deposits on apple surface (Malus domestica, Borkh)
Colodner, Adrian Dario; Magdalena, Jorge Carlos (Asociación Iberoamericana de Tecnología Postcosecha, 2013)El proceso de formación del depósito sobre las superficies vegetales está directamente relacionado con la capacidad de retención de las mismas y la concentración del producto en el líquido pulverizado. El depósito ... -
Cortina de aire para la aplicación de agroquímicos en fruticultura. Evaluación de sistemas de generación y transporte = Air curtain for agrochemical applications in fruit orchards. Evaluation of generation and transport systems
Behmer, Sergio; Mignone, César; Magdalena, Jorge Carlos; Benitez Piccini, Jose Edgardo; Di Prinzio, Alcides (Facultades de Agronomía, Ingeniería Agrícola y Ciencias Veterinarias, Campus Chillán, Universidad de Concepción, 2014)Las aplicaciones de agroquímicos en huertos frutales conducidos en espalderas que se realizan con pulverizadores de flujo divergente son desuniformes y presentan altas pérdidas de producto. La cortina de aire que generan ... -
Effect of concentration, application volume and addition of a surfactant on response to benzyladenine as thinning agent in 'Williams' pears
Curetti, Mariela; Rodriguez, Rodolfo Oscar; Magdalena, Jorge Carlos; Rodriguez, Andrea Betiana (ISHS, 2011-10)Benzyladenine (BA) is an effective thinning agent for Williams pear, the most important cultivar in Argentina. The aims of this research were: to find the minimum effective BA rate for increasing fruit size in Williams ... -
Effect of pressure on the quality of pesticide application in orchards
Di Prinzio, Alcides; Behmer, Sergio; Magdalena, Jorge Carlos; Chersicla, Germán (Instituto de Investigaciones Agropecuarias (INIA), Chile, 2010)Only part of the active ingredient used in agrochemical applications in orchards is retained on the trees. The product that is not retained is lost as sedimentation in the soil and as drift, the latter being a major source ... -
Effects of volume rate and spray pressure of an air-assisted sprayer on pesticide distribution and drift on pear prees
Magdalena, Jorge Carlos; Benitez Piccini, Jose Edgardo; Di Prinzio, Alcides Pascual; Behmer, Sergio Néstor; Villarroel, Luis Santiago; Gabbanelli, Matias Sebastian; Daga, Gabriel Antonino (ISHS, 2011-10)Pear orchards in Argentina are predominantly sprayed with an axial fan airblast sprayer. In this system, the forced air jet transports the spray droplets to the plant surface. The droplets are produced by an hydraulic ... -
Evaluation of low-drift nozzles in agrochemical applications in orchards
Behmer, Sergio; Di Prinzio, Alcides; Striebeck, Guillermina; Magdalena, Jorge Carlos (Instituto de Investigaciones Agropecuarias (INIA), Chile, 2010)Fruit production demands several phytosanitary treatments per year. The efficiency of these treatments is affected by product loss because of drift, a situation that is aggravated by frequent high winds and the presence ...
