Farmers are paying way more for fertilizer these days, but that is not the case for crop protection products, says an industry official.
“Almost all the products you can purchase today have come off patent in the last 15 years,” Rob McClinton, head of North America for Fuhua Chemical, told delegates attending FBN’s recent Farmer2Farmer VII conference.
Fuhua is the second biggest glyphosate manufacturer in the world behind Bayer.
WHY IT MATTERS: Farmers are dealing with mostly rising input costs.
McClinton said the 25 top selling active ingredients in the world are all off patent. The last few products remaining on patent are coming off by the end of the decade.
That means more competition and lower prices for those products, he said.
For instance, up until last year, only FMC manufactured chlorantraniliprole, a popular insecticide. As of today, 23 companies in China are either manufacturing the product or gearing up to do so.
“That ultimately means prices at the farmgate come down,” he said.
Prothioconazole is one of the biggest active ingredients in the world. The fungicide, marketed as Proline by Bayer Crop Science in Canada, is now manufactured by eight companies.
Bayer was selling that product for almost US$500 per gallon until its patent expired in 2023. FBN is now selling it for $190 per gallon.

“Think of what that means for the economics of your farm,” said McClinton.
He doesn’t fault the big-five chemical companies for charging a premium while they had a monopoly because it takes an average of $300 million and 10 to 12 years to bring a new active ingredient to market.
Chemical companies in flux
That is why no new active ingredients have been brought to market this decade. The next one is supposed to arrive in 2029.
John Appel, vice-president of category management at FBN, said the crop protection business is in the midst of an industry shakeup.
Corteva has split itself in two. The crop protection side of the business is now an independent company called New Corteva, while the seed business has become SpinCo.
BASF Agricultural Solutions and Bayer Crop Science are pivoting from commodity chemistry toward biologicals, digital agriculture and high-value formulations.
BASF has a minority initial public offering planned for 2027. BASF will remain the majority shareholder in the company post-IPO.
Bayer is closing its Frankfurt production facility by the end of 2028 after a 161-year history at the site.
FMC’s board is considering a possible sale of the $3.47 billion business.
“They have really struggled with earnings and revenue over the past year,” said Appel.
McClinton said manufacturers of generics are also experiencing financial problems. Hebang, which is one of the largest in China, posted revenues of $8 billion for the first three quarters of 2025 but only $13 million in profit.
“Can you imagine a business that big where you’re making that little money?” he said.
That is because more than 700 manufacturers are producing active ingredients in China. The competition is fierce.
