Key points

Before purchase, a number of factors should be taken into account when selecting a spraying system:

• the range of application volumes and the range of spraying speeds required;

• the crop types and fallow to be sprayed, including canopy size and stubble conditions;

• the products to be applied and the label requirements, including spray quality and downwind buffers of the products likely to be used;

• limitations of the current spraying system, as a guide to what may be useful when upgrading or replacing the sprayer; and

• the opportunity to access reliable service for the system when required.

  This module does not discuss optical spot sprayers (which are covered in Module 20). A summary table at the end of this module indicates which systems are better suited to support optical spot spray systems
