Effect of pressure on the quality of pesticide application in orchards
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 of environmental pollution. Unfavorable atmospheric conditions affect the u...

| description | 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 of environmental pollution. Unfavorable atmospheric conditions affect the uniformity of distribution and increase product loss. This can be mitigated by the utilization of larger drops. The objective of the present work was to evaluate the effect of service pressure on distribution in the trees and product loss by using a conventional hydro pneumatic sprayer. A fluorescent tracer was applied on fruit trees by an airblast sprayer, with two treatments: high pressure (1800 kPa) and low pressure (500 kPa). Samples were collected from the trees, in columns and from the soil. The results indicated that there were no differences between the two treatments in the total quantity of deposits recovered from leaves. There was one third less drift with the low-pressure than with the high-pressure treatment, whereas deposits on the soil were similar with the two treatments, with the low-pressure treatment presenting a higher concentration of deposits in the proximity of the treated row. In conclusion, the use of sprayer systems that operate with low pressure is a valid alternative to reduce environmental pollution because it tends to loss to the area where the treatment is being applied, without affecting deposits on the trees. |

Durante la aplicación de agroquímicos se retiene sobre los árboles sólo una parte del ingrediente activo utilizado. El producto no retenido se pierde como sedimentación en el suelo y como deriva, constituyéndose esta última en la mayor causa potencial de contaminación ambiental. Las condiciones atmosféricas desfavorables afectan la uniformidad de la distribución e incrementan las pérdidas de producto; éstas pueden ser mitigadas con la utilización de gotas de mayor tamaño. El objetivo del presente trabajo fue evaluar el efecto de la presión de servicio sobre la distribución en el árbol y las pérdidas de producto utilizando un pulverizador hidroneumático convencional. Se aplicó fluoresceína sobre frutales conducidos en espalderas con un pulverizador hidroneumático, en dos tratamientos: alta presión (1800 kPa) y baja presión (500 kPa) y se recolectaron muestras en los árboles, en columnas, y en el suelo. No hubo diferencias en la cantidad total de depósitos recuperados sobre las hojas de los árboles entre ambos tratamientos. La deriva fue tres veces menor en el tratamiento de baja presión, mientras que los depósitos en el suelo fueron similares entre tratamientos presentando el tratamiento de baja presión una mayor concentración de los depósitos en la proximidad de la fila tratada. La utilización de sistemas de pulverización que operen con baja presión se constituye en una alternativa válida para reducir la contaminación del ambiente, ya que tiende a delimitar el alcance de las pérdidas al área donde se realiza el tratamiento, sin afectar la cantidad de depósitos sobre el árbol.
