No time to waste to apply residuals

Despite exceptionally dry weather, winter wheat growers looking for first class control of grassweeds – especially bromes - should not delay residual treatments any longer advises Dow AgroSciences.

"A residual herbicide provides a foundation for effective weed control. It also allows some flexibility and choice in subsequent treatments," says Dow AgroSciences grassweed expert Stuart Jackson.

"In most parts of the country, there has now been rain which has soaked through the seedbed. And soil temperatures are still high, so grassweeds will come up thick and fast to pose a real threat to yields.

"For growers targeting sterile or great brome, we recommend a pre or peri-emergence treatment such as flufenacet or pendimethalin as soon as possible. This will be an ideal basis for a programme that then takes full advantage of Broadway Star* (pyroxsulam and florasulam) towards the end of this month or early November."

Broadway Star can be applied once the crop has reached GS11 and target weeds are actively growing with at least two true leaves. As it is contact acting it should applied with a recommended adjuvant.
