Wheat growers in the UK will have a new herbicide at their disposal this spring to tackle a wide range of grass and broad-leaved weeds.
Broadway Ultra builds on the success of Broadway® Star which has been a mainstay of early-season weed control for 14 years.
Corteva Agriscience has combined pyroxsulam and mesosulfuron-methyl in the new Broadway Ultra formulation, claiming it offers arable farmers the ability to control an extensive spectrum of weeds in a single pass.
“Broadway Star has a well-earned reputation as reliable, proven chemistry but with our new Broadway Ultra product the addition of mesosulfuron brings meadow grass control into farmers’ hands too,” said Alister McRobbie, cereal herbicides category Manager.
“We see this as a significant evolution. We now have two of the most effective post-emergence grass weed active ingredients in a single formulation and this should be something of real value to growers at the start of spring herbicide campaigns.”
Corteva says growers can expect excellent levels of annual meadow grass and ryegrass control and other problematic weeds are also retained. It expects growers with traditional rotations and on lighter land – where meadow grass and broad-leaved weeds are the key issue – to benefit the most from this innovation. It will be an effective product where there are mixed populations of grass weeds too.
Broadway Ultra’s label weeds also include brome, ryegrass, tame oats, wild oats and loose silky bent as well as difficult broad-leaved weeds such as cleavers, speedwells, mayweed, charlock, bur chervil and volunteer oilseed rape.
Trials conducted by Corteva demonstrate the same level of control of ryegrass, meadow brome and annual meadow brome as mesosulfuron- and iodosulfuron-containing herbicides.
Alister added that the same “act early” principles around application timing should be followed.
“Getting on top of key problem weeds early is as important as it ever was, and the challenging autumns we have had in recent years often shift the pressure for weed control to the spring,” he said.
“Broadway Ultra can be applied from 1 January right the way through to the middle of May, but cannot be used in the autumn. It can be safely tank mixed with – or followed by – Zypar® and has a broad range of ALS joint applications on the label, including combinations with ALS herbicides.”
The wettable granule should be applied with an adjuvant at a rate of 100g per hectare and comes in a 500g pack. A 5m reducible buffer zone applies.
