Spotlight on technology – Snap Card App
Continuing with the theme of improving spray application (see article in this issue), the focus on this editions ‘spotlight on technology’ is an app that gives spray applicators the ability to assess the coverage they are achieving with their spray-rig. Applicators can place water sensitive paper (available from rural retailers) on their target, be it the crop, a weed or a mango leaf. They then spray the target and come back to collect the water sensitive paper. The applicator can then use the app to assess the percentage of coverage.

The user can compare different spray-rig settings to assess what is giving the best results for their current environmental conditions.
The app was developed by the Department of Agriculture and Food, Western Australia, and the University of WA’s (UWA) applied entomology program. This was supported by funding from the Council of Grain Grower Organisations and the GRDC.
