Precision Weed Control – Options and Costs

 Megan Star & guest presenters

Precision weed management technologies are reshaping how Australian grain growers tackle rising input costs. Join Megan Star and guest presenters as they unpack real-world case studies evaluating the economics of adopting optical spot spray technology (OSST).

The session will explore what actually changed on farm — from chemical use and spray programs to operational efficiency — and what it meant for costs and returns. Learn how ongoing adjustments to existing platforms helped growers reduce chemical spend, improve spray efficiency, and maximise the value of their investment.
