Arable farmers across the UK and Ireland have a new name to turn to for crop inputs, as one of the world’s biggest crop protection companies enters the market.
Rainbow says its UK launch will follow its proven pattern: country-specific actives and formulations drawn from its portfolio of over 8,600 registrations, supported by robust manufacturing controls and local technical support, a policy that has seen its presence steadily grow to more than 110 countries on five continents.
“Rainbow’s ambition for the UK is to encourage growers to re-evaluate their attitudes towards post-patent crop protection,” says Simon McMunn of AgTIgrow, Rainbow’s UK partner.
“In practice, that means prioritising quality and reliability, in turn delivering product confidence. Consistent delivery of all three elements will raise expectations of what post-patent chemistry can deliver, both in the field and to the bottom line,” he explains.
“I believe it’s an offer that will resonate with a progressive, professional and technical mindset – the typical modern UK arable producer.”
Founded in 2000, Rainbow has become China’s biggest crop protection exporter. With a fully integrated supply chain end-to-end, from R&D to delivery, Rainbow’s 10 modern, automated plants ensure both consistent quality and competitive pricing.
“With that kind of set-up, it should be no surprise to learn that it has been contract manufacturing for global agchem brands,” points out McMunn. “British farmers have probably already used products manufactured with Rainbow technology.
“Rainbow brings that same disciplined approach to its own post-patent portfolio — not as a mass-generic reseller, but with a deliberate strategy built on tightly controlled production, market-specific formulations, and a focus on performance, trust and value.”
“It produces its own portfolio to the quality one would expect from a familiar brand, but pursuing a new post-patent model.”
McMunn says more than a dozen UK registrations will be available at launch, spanning herbicides and fungicides. Every product carries full UK statutory labels, compliant packaging and local technical support. A further 12 registrations are in the pipeline for approval during 2026, a number which is expected to increase as interest grows: the company secures around 1,000 new registrations globally every year.
Rainbow’s technical support extends to more than agronomic aspects, McMunn points out. “The UK is a long-term prospect for Rainbow. That means a long-term commitment to defending re-registrations of active ingredients through both the UK and EU regulatory systems, as appropriate, providing UK farmers with assured, sustainable agronomy in the years ahead.
