Corteva announces arrival of new Broadway^® Ultra grass weed herbicide for spring 2025

Wheat growers in the UK will have a new herbicide at their disposal next 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, offering arable farmers the ability to control an extensive spectrum of weeds in a single pass.

Managing herbicide resistance in broad-leaved weeds

Herbicide resistance in broad-leaved weeds is relatively rare when compared to resistance in grass weeds such as blackgrass or ryegrass, but incidence is on the increase and there is concern that it may now be found in further species. Our latest article by Corteva’s Field Technical Manager, Hugh Guinan, delves into the rise of resistance in some of the most affected weeds like poppy, chickweed, and mayweed. Learn about the development of resistance, early detection signs, and effective management strategies to combat this issue.

Here are our tips to avoid broadleaf-weed resistance and get the most out of your herbicides:

Target weeds when small and actively growing. For weeds such as ALS poppy, control should start in the autumn with pendimethalin or cinmethylin and follow up in the spring with an alternative mode of action such as Arylex (found in Pixxaro^® or Zypar^®).
If you are applying complicated, multi-way tank mixes, don’t be tempted to split out the herbicides if there are too many products in the tank. Keep the herbicides together.
Minimise the use of ALS herbicides in the rest of the rotation, only use them where you really need them.
Maintain good spray records and always investigate cases of poor weed control.
Consider spraying off patches of poorly controlled weeds before seed set if you suspect resistance. This will avoid seed return and problems later down the line.
Collect seed or tissue samples and get them tested if resistance is suspected.

Corteva’s top tips for OSR growers this December

Grab some fresh winter air and chase those pigeons off your crop!
If you haven’t applied your propyzamide already, remember that the cut-off for Astrokerb^® & Kerb^® Flo 500 applications is the end of January.
Do your final stewardship checks before applying propyzamide.
Needing extra broad-leaved weed control? Belkar^® can be applied until the end of December. You can tank mix Belkar with Astrokerb or Kerb Flo 500.
Calibrate your fertiliser spreader ready for applications of N and Sulphur.
Spring will be here before you know it. As your crop opens up, review the broad-leaved weed pressure. Order Korvetto^® ready for the use period, for the ultimate spring clean.
