Observations

University of Adelaide, Professor of weed management Chris Preston gave the following recommendations for spraying weeds at a recent Dried Fruits Australia Crop walk in November.

• Expensive treatments work but don’t need to be used all the time. They can be used strategically to stop seed set particularly with ryegrass.
• Consider a cover crop in the interrow to compete with weeds that will help to reduce the build up of weed seeds in the system.
• Small weeds are easier to manage than large weeds – spray early to target small weeds even if it means one more control may be required. This will help with long term weed management.
• Get your application right – make sure water rates are not too high so as not to dilute the surfactant that is sprayed with glyphosate as diluting the surfactant will give a poorer result.
• If you can’t reduce the water rate consider increasing the surfactant in the mix to improve the efficacy of glyphosate.
