1. Weed Mapping

2. Weed Mapping
•What is it?
•Why?
•What are the benefits?

3. What is it?
•A biomass image using NDVI
•It is a great tool for identifying high density
weed areas
•These areas can then be treated in isolation
•Even more benefit in large scale paddocks and
or farms

4. NDVI Capture via Greenseeker

5. Weed Areas via Greenseeker

6. Weed Areas via Satellite

7. Why?
•So what? we know there are weeds in the
paddock.
•However weed spectrum is never even across a
paddock
•Target high density areas differently
•Higher sowing rate
•More robust pre emergent package
•It’s a numbers game

8. Weed Areas via Greenseeker

9. Weed Areas – Prescription Spray

11. Weed Areas – Prescription Spray

12. What are the benefits?
•222 hectares
•31 hectares high pressure
•191 hectares low pressure
•Blanket of Sakura = $8658
•Prescription Pre Emergent Package (Trifluralin as blanket
and Sakura in high pressure = $3873
Saving of $4785
