Phil has fixed a spray boom on the back of his ute, which allows spraying of the rows from the comfort of the ute. We worked from the northernmost steel monitoring post, back and forth across all rows to the fence, except the very last row. The spray mix used was glyphosate and simazine with a wetting agent.
It’s great to have the flexibility to spray opportunistically whenever the weather is suitable instead of being dependent on the whims of contractors.
