Malton & Norton Golf Club in north Yorkshire largely eradicated the weeds following two annual applications of a powerful systemic post-emergence herbicide on fairways and semi-rough areas.
Course manager Richard Jacques sprayed the 27-hole parkland course with Praxys from Everiss after alternative treatments failed to offer long-term control, he said.
"Within three weeks the weeds were starting to die back and we saw very little recovery during the rest of last year," he said. "Although comparatively few problem weeds were evident in spring 2012, I went for total kill and applied Praxys in May.
"In the long run the product’s effectiveness means we will be saving a great deal of money through a combination of very low dose rates and the removal of the need to continually respray.
"Our location, surrounded by farmland, means we’ll never totally eradicate difficult weeds. But we will now be able to control them with certain knowledge of success and at much lower cost."
