Bayer’s New Total Herbicide

Bayer’s New Total Herbicide: A new pre and early post-emergence total herbicide, for controlling annual and perennial weeds, has been released by Bayer into the Irish market, and is now available to purchase.

Pistol® Flex brings a new active ingredient, to the market for broad spectrum control over a wide range of uses including treatments applied to open soil, gravel surfaces, fence lines, industrial areas and railway ballast.

Greg Collins, of the Bayer Turf Solutions Team, explains that the herbicide’s dual active formulation contains 360g/kg diflufenican and 10g/kg iodosulfuron-methyl-sodium.

“This gives a two-pronged approach to weed control, targeting germinating seedlings through residual action, and the leaves on contact.

“The product provides excellent control for even the hardest to tackle weeds and is also compatible for use under a variety of tree and shrub species.”

Resistance management

Greg adds that using Pistol® Flex can help amenity contractors to minimise resistance as part of an integrated vegetation management (IVM) programme.

“The combined active ingredients give a dual mode of action and therefore reduce the chance of resistance occurring.

Flexible applications

“The herbicide can be used flexibly, as a standalone application on bare ground for pre-emergence stages. Alternatively, after the two leaf post emergence stage it can be mixed with glyphosate to enhance performance.

“And due to this robust performance in different environments, the product offers good residual control for three to four months, which may save the operator returning for repeated applications,” says Greg.

Pistol® Flex is available to purchase from Unichem and Sprayclear Environmental and is supplied in convenient 10g sachets to easily add into a knapsack or 500g packs for those that need to treat a larger area.
