UK wheat growers will have access to a new herbicide from Corteva Agriscience next spring, said to handle a wide range of grass and broad-leaved weeds.
Broadway Ultra is the latest generation of spray, building on the company’s Broadway Star which has been available for 14 years.
It combines pyroxsulam and mesosulfuron-methyl for broad-spectrum control in a single pass, according to the company.
“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 states that the new formulation offers excellent levels of annual meadow grass control, as well as in ryegrass and other problematic weeds. Those with traditional rotations, working on lighter land, are likely to see the most benefit.
The label also shows control of brome, tame oats, wild oats and loose silky bent, as well as broad-leaves such as cleavers, speedwells, mayweed, charlock, bur chervil and volunteer oilseed rape.
“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 shifts the pressure for weed control to the spring,” Alister 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 Corteva ALS herbicides and those of other manufacturers.”
The 500g wettable granule pack should be applied with an adjuvant, at a rate of 100g per hectare. A 5m reducible buffer zone also applies.
Alister concluded: “We are really pleased to be able to bring this product to the market in the spring and will have good availability of the product for growers who want to experience the new formulation on their farms.”
