Ryegrass control needed to boost promising season

With the season looking promising for growers in the Dubbo area, they’re being encouraged to get in early to treat grass weeds that are part and parcel with good growing conditions.

“With at least 80 per cent of the growers I work with, things are coming along really well,” says local Dubbo agronomist, Dave Strahorn from Delta Agribusiness.

“Cereal yields average between 2 to 5 tonne per hectare, and at the moment we’d expect this year’s yield to be at the higher end of that spectrum.”

“The biggest issue we have is that we are seeing early germination of some grass weeds, mainly ryegrass which is an annual problem for both wheat and barley.”

Dave says he is advising clients to treat ryegrass with the pre-emergent herbicide BOXER GOLD®, which also offers split application for in-furrow control.”

“We know that with BOXER GOLD we can target them with a single application or split appliction where needed. You can also use it with mixing partners to get better weed control, including other pre-emergent herbicides and non-selective herbicides like glysophate and GRAMOXONE® 360.”

Curban grower, Gary Weston, says he will use BOXER GOLD on his barley paddocks this year, mixing it in-tank with trifuralin.

Gary says BOXER GOLD works well with his cropping strategy, where he sows his cereals a bit deeper, at 40 to 50 mm.

“Sowing at that level helps avoid having seed in the top profile which dries out just as the crop is emerging.”

“This strategy works well with pre-emergent treatments as well as allowing us to keep the germinating seed well away from the chemical,” says Gary.

“Some years we may have to use a follow-up post-emergent spray to control any escapes that germinate under a clod - but each time we get the pre-emergent right, we usually negate the need for a mop-up spray,” he says.

BOXER GOLD, from Syngenta, is the industry leading pre-emergent treatment of Annual Ryegrass in Australia.

It offers flexible application with seven-day incorporation, residual control and no plant-back restrictions, so rotational crop strategies can be fully utilised.

“Seven days to incorporate is excellent as growers are under the pump and that offers real flexibility,” says Dave.

“No plant-back restrictions add to that. Sakura*’s plant-back to grazing oats and Lucerne are just too long, especially now that livestock are back on the agenda in the area.”

“It does a fantastic job on Annual Ryegrass when we are having post-emergent resistance issues, so I recommend it regardless of resistance issues if we know Annual Ryegrass is there.”
