Flufenacet and mesosulfuron set for range extensions (press release)

Cambridge, 31st, October, 2013

Existing active substances will form the backbone of weed control products over the next five years, according to Bayer CropScience, while the search for new modes of action continues.

Speaking as one of the sponsors of CropTec - the new arable technical event -  Chris Cooksley, the company’s marketing manager, told delegates about the company’s quest for new herbicides to control black-grass.

“Bayer CropScience alone will spend £4.2bn on R&D in the next five years,” he said.  “Unfortunately the number of companies investing in R&D has reduced in recent years, but Bayer CropScience is still actively searching for the next Atlantis WG.”

“Discovery rates of potential new active substances remain good and, there are some promising actives in the early stages of development,” he says.

But, he pointed out, it can take up to ten years and £300m to bring a new active substance to market. “Right now, it is too early to tell if the ones we’re looking at will pass the myriad of tests required to make them a commercially viable proposition.

”With no new modes of action on the horizon, it seems highly unlikely that we will see a new revolutionary product in the next five years. So where next?

“In the UK, Bayer CropScience has plans to launch beneficial line extensions to the flufenacet and mesosulfuron ranges,” said Mr Cooksley. “They will be very useful tools to add to our armoury, but they are not new modes of action. They will not be the game-changer that Atlantis WG (mesosulfuron and iodosulfuron) was ten years ago,” he cautions.

That’s why, Mr Cooksley emphasised, cultural controls - ploughing, stale seedbeds, delayed drilling, crop rotation - and well-planned programmes of stacked residual herbicides, must form the backbone of grass-weed control both now and in the future.”

Mr Cooksley said this would hold true even in the event GM technology is approved in the UK.

“GM is the nirvana many have in their minds but while total-herbicide tolerance would seem a perfect solution, we know glyphosate resistance is a real threat and there isn’t consensus within Europe to introduce the technology. 

“Even GM needs support in the form of cultural controls,” he added. “So we might as well start honing our skills now.”

Those skills must also include learning more about black-grass biology, resistance and control, he warned.

“Most UK distributors are now looking beyond chemical controls. Agrii, Agrovista, Frontier and Hutchinsons are amongst those investing in long-term projects that consider everything from variety choice and cultivations to root exudates and companion crops.”

“And then there’s precision farming, aerial weed mapping, remote sensing and application, natural chemical usage...the list goes on.

“What’s important is while new modes of action are some way away, as an industry we must cultivate our collective knowledge and the will to work around the problem. It’s the only way in which we’ll develop solutions that keeps farming profitable for many years to come.”
