US agriculture is doing it tough with American farmers finding it hard to turn a profit in an era of low commodity prices and high costs, despite a system of support well beyond that available to Australian growers.
First-time Western Australian grower users of the Integrated Harrington Seed Destructor (iHSD) are looking forward to adopting the latest developments with the technology for the upcoming grain harvest, as well as further improving their weed control, chemical use and soil nutrition through reduced burning.
Now is the time to take pre-emptive action to reduce the incidence of glyphosate resistance in weeds, recognising the need to implement management practices that help protect the efficacy of glyphosate in farming systems.
As dry conditions continue to impact on crops in many regions of Australia, affected growers will be faced with difficult decisions that will have long lasting effects on the weed seed bank.
Shielded spraying and zero row spacings are helping a Victorian farmer keep on top of the weed burden.
A survey has revealed 43 per cent of Australian grain growers are currently practising harvest weed seed control (HWSC) and this is set to double within the next five years.
Dry season agronomy is difficult. In affected areas there is a reasonable chance that pre-emergent herbicides applied at or before seeding will not work as well as they usually would, even when it does rain.
The lack of autumn rains in areas like the Eyre Peninsula in South Australia and no follow-up rain for dry sown crops in some Western Australian districts means there will be many crops with variable establishment and variable growth rates, making weed control more challenging.
The Harrington Seed Destructor, chaff carts and narrow windrow burn techniques are all equally as effective as one another at reducing the weed seed burden.
Growers should seriously consider the value of pasture and fodder crops to regain control of herbicide resistant weeds.
