Q1. What is Spraywise Decisions?

It is supported by Nufarm for the exclusive use of its Australian customers, agricultural retail chains and other interested users.

Q2. What can Spraywise Decisions do for me?

Spraywise Decisions predicts weather on your farm up to 14 days ahead and records last 14 days of weather. It automatically combines weather parameters to derive industry standard Delta T values as a guide to the suitability of prevailing conditions for spraying.

Q3. What features of Spraywise Decisions are unique?

Spraywise Decisions has many unique features. These include the seamless ability to assess the prevailing and recent weather conditions over your farm. Many other short term forecasting websites provide details only to the local bureau weather station. Our methods to determine climatic information between these weather stations focuses on providing users with relevant and accurate data that is otherwise unavailable.

Q4. How can I subscribe to Spraywise Decisions and what payment options do I have?

Spraywise Decisions is offered by Nufarm to all rural landholders and any other interested user across Australia on a 7 day fee-free basis. Thereafter, users will be required to remit a modest fee to obtain an ongoing subscription that needs to be renewed each year.

The annual subscription fee is set at $120 + GST per user providing access to 4 assessment locations. The fee will be indexed for inflation and may be increased based on new developments and upgrades. Alternatively, users who wish to take advantage of up to 20 assessment locations can subscribe to the Corporate level subscription type for a cost of $275 + GST for a period of 12 months.

Q8. Am I restricted to my local area of interest?

Users can zoom and pan using the Google Maps interface showing either the terrain (default) or satellite layer. You can identify map features and locate, move, edit, rename or delete movable points anywhere across Australia.

Q9. What is Delta T?

Delta T is one of the standard indicators for acceptable spray conditions. Delta T is calculated by subtracting the wet bulb temperature from the dry bulb temperature. The diagram below relates air temperature and relative humidity to values of Delta T. When applying pesticides, Delta T should ideally be between 2 and 8. Users can select either Medium or Coarse spray quality to adjust the Delta T range.

Q10. How accurate and reliable is Spraywise Decisions?

Spraywise Decisions utilises industry standard forecasting models used by leading global weather agencies to generate parameter specific predictions. The system incorporates definitive accuracy estimates by comparing predicted versus recorded values on an ongoing basis at the nearest of 270 stations for which hourly recordings are made by BOM. A “grey zone” on each meteogram with increasing width signifies that accuracy generally declines in proportion to the length of the prediction time frame.
