The weeds are coming.
The Grains Research and Development Corporation said heavy rainfall in parts of the southern cropping region during recent weeks could be likely to promote summer weed growth, robbing cropping soils of valuable moisture and nutrients.
It said grain growers should therefore be encouraged to control weeds as soon as possible, before they became a larger problem.
Uncontrolled weeds not only reduce soil moisture and nitrogen, but could also lead to equipment blockages that impede efficient sowing operations.
Controlling summer weeds can also minimise disease and insect issues that can occur when a ‘green bridge’ of weeds and volunteer cereals is allowed to survive over summer.
To assist growers with their summer weed control efforts, the GRDC offers a number of useful resources, including the Summer Fallow Weed Management Manual, available at www.grdc.com.au/GRDC-Manual-SummerFallowWeedManagement
