Isoflex™ active Overview

FMC's newest herbicide active Isoflex™ active is coming to the UK market and is set to deliver a brand-new mode of action for the control of grassweeds and broadleaf weeds in winter cereal crops.

Isoflex™ active is the trade name of Bixlozone, a new herbicide ingredient from the isoxazolidine family discovered and developed by the FMC research and development organization. It offers growers operational flexibility and lasting control of key grass weeds, including those with developed resistance to other herbicides, as well as some broadleaf weeds.

The mode of action is totally new to the cereal herbicide market. It acts by inhibiting the ability of susceptible weeds to produce carotenoids, molecules which are vital to photosynthesis and the production of amino acids. Inhibition of carotenoids leads to the characteristic bleaching and colour-change symptoms observed in weeds treated with Isoflex™ active.

Isoflex™ active has activity on a broad range of weeds, including activity against key grassweeds such as blackgrass, ryegrass and annual meadow grass. It also provides control of a wide range of broadleaf weeds.

Trials have shown Isoflex™ to be safe in cereals, oilseed rape, potatoes, sugar beet, maize, and pulse crops.

The first product utilising Isoflex™ active to be brought to market will be for use in Winter Wheat & Winter Barley

The product is currently going through the registration process and updates will be shared in due course.

Once FMC achieves initial product registration, Isoflex™ active will first be approved for autumn applications to Winter Wheat and Winter Barley

Isoflex™ active’s mode of action is new to the UK Cereal market and will bring a novel tool to farmers armouries. Use of new chemistry, alongside existing products, can contribute to an effective resistance management strategy.

Yes, following extensive field trials and testing we are confident in Isoflex™ active ability to be very flexible and easily tank mixed or sequenced with other approved products, a key component of integrated weed management.
