Weed control in wheel tracks

Numerous factors influence poor weed control in the wheel tracks of the sprayer. This can include poor spray deposition and excessive dust.

Using additional wheel-track nozzles for knockdown 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 'Weed control in wheel tracks' fact sheet covers these topics to help spray operators improve weed control in wheel tracks during summer fallow spraying.
