A new weed identification mobile app developed for the cotton industry could have wider application across a range of other crops in the broadacre farming sector.
Harvester-integrated weed seed control is now within reach of many more growers following the release of a vertical, mechanical-drive version of the popular Integrated Harrington Seed Destructor (iHSD).
Rather than relying solely on a knockdown strategy to control summer weeds, growers are increasingly introducing a pre-emergent herbicide in the fallow phase, to assist in tackling these problems.
Growers should act early and stay on top of emerging weeds during summer and autumn to optimise soil moisture and nutrient conservation and minimise the ‘green bridge’ for carry-over of pests and diseases.
With pressure on to find effective non-herbicide weed control tactics, evidence is mounting that creating stiff competition from summer crops really can be an effective weapon in the war on herbicide resistant weeds.
Recent changes to 2,4-D label instructions have re-focused attention on the need to avoid night spraying, particularly after 10pm through to after sunrise.
Researchers have designed a strategy to counter glyphosate-resistant weeds in cotton farming systems.
In the battle against herbicide resistance, stopping ryegrass seed set pre-harvest in canola is all about timing. Sometimes the timing window lines up, other times it does not.
Southern region grain growers – in areas where ground cover is sufficient – should control summer weeds at the earliest opportunity to optimise the potential for a multitude of agronomic and financial benefits.
A north west NSW farming family having difficulty controlling Johnson grass in sorghum has found the introduction of cotton as a dryland summer crop option has given them a new option for controlling Johnson grass and a range of other weeds.
