The generic crop protection market is on the verge of significantly expanding over the next several years. From 2023 to 2028, there will be 19 active ingredients (AIs) that are coming off patent, according to S&P Global. This includes 11 fungicides, four herbicides, and four insecticides. Next year will be especially active in the post-patent market, with 12 AIs expected to be made available following their patent expiry. For the full list of active ingredients coming off patent, in alphabetical order, view the slideshow below.

As a result of these pesticides coming off patent, generic manufacturers face a bonanza of market opportunity and the ability to update their portfolios with new chemical technology, particularly in global markets like India.

“The fact that these molecules are going to come out of their patent period will substantially expand the offerings of Indian companies to people at home and abroad alike and may help fetch extra revenue,” said Pradip Dave, Chairman of AIMCO Pesticides Ltd. and President of the Pesticides Manufacturers & Formulators Association of India (PMFAI) in this article in 2021. “The agrochemical sector is deeply interested in the molecules that are going to be off-patented as it creates an opportunity for its own commercial development. Pesticide companies, especially in developing countries, wait for generic active ingredient molecules as it provides huge opportunities for generic manufacturers to provide agrochemicals at a reasonable affordable price for farmers to protect their yield from pests and disease.”
Generic producers constitute about 30% of the global pesticide industry, Pradip said, mainly due to an increase in the number of off-patented molecules and decline in new active ingredients, both of which favor the generic pesticides industry which has seen a faster growth as compared to the inventor or R&D-based companies recently.
An expanded generic crop protection market will also present some challenges for suppliers, says David Li, Marketing Director for SPM Biosciences and author of AgriBusiness Global’sChina Price Index.

“In China’s pesticide supply market, the red ocean of competition has turned every supplier into a “prisoner,” wrote Li in a recent column. “The productivity boundaries of the generic active ingredient (AI) (off-patent pesticide) market are being reshaped as global farmers’ willingness to pay decreases and the price of generic products gradually decreases. At the same time, the field of alternatives to generic pesticide products is also squeezing the overall value of the generic AI market.”
