Application Considerations for in-Crop herbicide use

  • Knowledge of a product’s translocation and formulation type is important for selecting nozzles and application volumes.

  • Evenness of deposit is important for poorly or slowly translocated products.

  • Crop growth stage, canopy size and stubble load should in uence decisions about nozzle selection, application volume and sprayer operating parameters.

  • Robust rates of products and appropriate water rates are often more important for achieving control than the nozzle type, but, correct nozzle type can widen the spray window, improve deposition and reduce drift risk.

  • Travel speed and boom height can affect control and drift potential.

  • Appropriate conditions for spraying are always important.
