Growers are urged to protect glyphosate’s future, as a warning has been issued following the country’s first confirmed case ...

For Italian ryegrass, early management is critical, with herbicide applications in February proving significantly more effective than those in March or April.

After Italian ryegrass with resistance to high rates of glyphosate was discovered on a Kent farm earlier this year, it was zero-till systems researchers pinpointed as particularly at risk.

“The suspect Italian ryegrass population was tested with different glyphosate products at four rates. Of concern was the fact that all products were ineffective, even at the maximum allowed rate.

Teagasc has confirmed the first case of glyphosate-resistant Italian ryegrass in Irish cropping systems. The finding marks a significant development, as glyphosate is a widely used herbicide with ...

Italian ryegrass is a problem weed on some tillage farms. New research from Teagasc has shown that an Italian ryegrass population in Ireland is resistant to the herbicide glyphosate. This is the first ...

Because Italian rye-grass shook off glyphosate at the maximum label rate, it now finds itself in the spotlight. Of course, Italian rye-grass can resist other herbicides too, with the first cases ...

Weed resistant to key herbicide found in UK Scientists say glyphosate was not effective on Italian ryegrass in multiple fields on a Kent farm.

An Italian ryegrass plant in the UK has been found to be resistant to glyphosate at the label rate. Research by ADAS and NIAB identified a single field population of Italian ryegrass which was ...

Italian ryegrass is the only weed with suspect populations in the UK. Extensive testing of black-grass and a 2023 survey of 166 brome samples found no populations with glyphosate resistance.

Italian ryegrass has been growing in several fields on a farm in Kent. Scientists have confirmed it is resistant to glyphosate, considered to be the most effective weedkiller on the market.

Paul Neve, professor of crop science, University of Copenhagen, said Italian ryegrass resistance “hasn’t exploded into a huge problem” since the first cases in Australia in the 1990s.
