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.

Payment options vary according to the identity of individual users of SprayWise Decisions. Potential users fall into two distinct groups.

  1. Users that are existing members of the Nufarm Top Cropper program will have the option of using loyalty points or a combination of points and payment towards their annual subscription.
  2. Users that are not members of the Nufarm Top Cropper program are welcome but will be required to remit an annual subscription fee to maintain access.

The initial annual subscription fee is set at $120 + GST per user. The fee will be indexed for inflation and may be increased, but only after a significant amount of additional functionality has been added.

Q5. What should I do if I forget or want to change my username or password?

If you know your username, use the Retrieve Password option at the log-on page to retrieve your password, or by using the Change Password option within the My Profile options.

If you have forgotten your user name, select Register Now and re-enter your details. The system will remind you of your user name if your re-entered details exactly match Registration Information in the SprayWise Decisions database. If you are unsuccessful, contact SprayWise Decisions (see Question 10).

Q6. How does SprayWise Decisions know what locality is of most interest to me?

The Suburb/Town details in your registration information will automatically assign you a fixed primary point of interest at the centre of the relevant Postcode and set the default extent of the map and satellite imagery viewer to a buffered distance around the nearest relevant Local Government Area (LGA).

Q7. How many individual points can I register?

Each subscriber can locate, move, edit, rename or delete 3 additional points for which to obtain weather forecasts and spray condition predictions. Corporate subscribers are permitted to register up to a total of 20 individual points of interest.

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

Users can zoom and pan map themes and satellite imagery, identify map overlay features and locate, move, edit, rename or delete movable points anywhere across Australia.

Q9. What is Delta T?

Delta T is becoming 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. Delta T Calculation
