The three-year headline sponsorship deal includes the annual IOG Industry Awards, including sponsorship of the IOG Young Groundsman of the Year, along with the Young Groundsmen's annual Conference.
The agreement follows Rigby Taylor's funding of sets of technical tools for each of the nine regional pitch advisors of the IOG-led Grounds and Natural Turf Improvement Programme, which is targeted at raising the standards of sports surfaces as well as the understanding of sports turf management practices among grassroots clubs.
Rigby Taylor's marketing director Richard Fry said: "This is an exciting opportunity to provide support to a key industry association and its membership, and is an extension to the support we've provided in the last.
"This latest sponsorship is a mark of the confidence we have in the forward-thinking strategy being adopted by the IOG and, through such sponsorship, it is our intention to provide increased support and assistance."
Geoff Webb, IOG chief executive, added: "This agreement is testament to the fact that the IOG Awards now truly represent the industry's support and commitment to recognising and rewarding best practice in sports turf management. Coupled with the proactiveness of Rigby Taylor and Top Green in also supporting up and coming young grounds staff, we are delighted to now have a firm platform to build opportunity and reward excellence."
