THIS summer has been an exceptional period of good weather that includes rain and milder temperatures that have exacerbated the growth of weeds.
The New South Wales Department of Primary Industry says growers who experienced rainfall over summer can protect their future profits by making weed control a priority ahead of planting in autumn.
Summer weed management will ensure any soil moisture and nutrients can be conserved for the coming season, while also minimising ‘green bridge’ for carry-over of pests and diseases.
Research advocates spraying summer weeds when they are young and actively growing as the most effective way to kill them and protect potential crop profitability.
Timely spraying of weeds prompted by wet conditions this summer will protect soil water, nutrients and future crop profit.
Weed management is estimated to cost Australian grain growers approximately $3.3 billion every year. This figure does not take into account ongoing costs from yield and nutrition losses.
