Grain growers in the southern cropping region are being advised that they can take action to improve weed control in wheel tracks during summer fallow spraying. 

A Weed Control in Wheel Tracks Fact Sheet, produced by the Grains Research and Development Corporation (GRDC), details measures that can reduce poor control of weeds in the sprayer’s wheel tracks and adjacent areas during summer fallow applications. 

Lack of weed control in these areas can be the result of poor spray deposition, excessive dust or a combination of the two. The Fact Sheet states that using additional wheel track nozzles for knock down herbicides (non-residual) can improve deposition and the level of control in the wheel tracks and adjacent areas. 

Generally, dust is only reduced when soil moisture is present, speed is reduced or more permanent wheel tracks are used. The Fact Sheet is now available for viewing and downloading via www.grdc.com.au/GRDC-FS-WheelTrackWeedControl.
