ISO 24253-2:2015 specifies a method for field measurements to determine the quantity and distribution of spray in a field crop, treated by horizontal boom sprayers with downward directed application. It can be used for nursery trees and small size bush crops (young currants) when sprayed with boom sprayers. NOTE When interested in the spray deposition over width of the crop canopy, it is advised to use ISO 22522. ISO 24253-2:2015 allows flexibility in the arrangement of field tests, but specifies standardized measurement procedures that are useful to be able to compare the results from different field experiments or to compare with laboratory tests, such as that specified in ISO 5682-2. ISO 24253 is not intended for use in or for a regulatory framework.
Abstract
Overview
ISO 24253-2:2015 - Crop protection equipment: Spray deposition test for field crop - Part 2: Measurement in a crop specifies a standardized method for in-field measurement of spray quantity and distribution within crop canopies when treated by horizontal boom sprayers with downward directed application. The standard supports comparable field experiments and linkage with laboratory tests (e.g., ISO 5682-2), but is not intended for regulatory use. It can also be applied to nursery trees and small bush crops (young currants) sprayed with boom sprayers.
Key topics and technical requirements
- Measurement targets: deposition on top of canopy, at designated points inside the canopy, and on the ground beneath the vegetation using collectors (artificial or plant material).
- Tracers: use safe, stable tracers with high recovery (>90 %, preferably >95 %) - examples include metal ions, food dyes (tartrazine), and fluorescent dyes (sodium fluorescein).
- Collectors: artificial collectors must demonstrate good recovery and low background emission (blank readings ≤ 0.1 % of sprayed average); background coefficient of variation should be
