Amenity contractors can take back control from the weeds

Herbicide resistance is an increasing issue for the UK turf and amenity sector. Bayer’s new broad-spectrum residual herbicide is already showing effectiveness, keeping weeds at bay for up to four months

Resistance issues and product losses continue to place pressure on amenity contractors, but Bayer’s new residual pre-emergence herbicide helps to tackle this ongoing problem. Bayer national account manager Lewis Blois says: “We are always working hard to bring new innovative formulations and sustainable solutions to the amenity sector. Our new pre-emergence herbicide will help contractors to continue to successfully manage weeds at a time when many products are being lost from the market.

“Valdor® Flex [MAPP:19033] contains a new and unique formulation,” Blois continues. “The pre-emergence herbicide contains two active ingredients that prevent the emergence of a broad spectrum of weeds for up to four months, reducing the frequency of traditional herbicide applications. The product provides excellent residual control for even the hardest to manage weeds on a wide range of surfaces, including open soil, gravel, and industrial areas,” he adds.

Resistance management
Blois explains that because of the combination of active ingredients, Valdor® Flex acts as a valuable tool for resistance management within the weed control sector. “The herbicide provides good control of numerous weeds, while the two active ingredients, diflufenican and iodosulfuronmethyl-sodium, help to minimise the risk of resistance with two different modes of action.”

Flexible applications
“Valdor® Flex can be used as a stand-alone application on bare ground before weed emergence. Alternatively, if weeds are present it can be mixed with RoundUp® or fatty acids, which provides the initial knockdown, while Valdor® Flex provides residual control preventing subsequent weeds emerging for up to four months,” Blois continues.

Blois says the correct amount of product should be mixed to cover the given spray area for that day. But, he explains Valdor® Flex is stable in water for at least 24 hours, so if for some reason there is any spray solution left in the tank it can be used the following day. “It’s easy to mix in a knapsack or tractor-mounted sprayer with very little dust given off, providing improved operator safety,” he says.

“Valdor® Flex is also available in a range of pack sizes. The 10g sachets are the ideal dose to be mixed in a knapsack sprayer with 10 litres of water. For contractors requiring larger quantities, the 500g bottle may be more cost-effective to use in a tractor-mounted sprayer.”

Demonstrable effectiveness
Hortech operations manager John Shufflebotham says: “We trialled Valdor® Flex on a couple of our utility sites. It was applied with glyphosate as we already had some weed growth because of the time of the season and wanted residual control to help prevent more weeds emerging.

“We found the combination worked effectively, knocking down weeds while helping to stop the emergence of new weeds for several weeks. As a result of this prolonged effectiveness, we were able to reduce the amount of herbicide used on follow-up treatments, saving us time and money.

“Valdor Flex® was easy to use, and the Bayer Amenity Solutions Team were very supportive during the trial. They were always at the end of the phone to offer advice when needed. With limited herbicides on the market, it’s great to have a new product to add to our armoury which allows us to rotate active ingredients helping to reduce the risk of resistance,” adds Shufflebotham.
