PI Industries makes and sells crop-protection chemicals for farmers and also manufactures advanced chemicals for drug companies under contract.
PI Industries is an Indian company that does two related jobs. The first is making agrochemicals — the sprays and treatments farmers use to protect crops from insects, weeds, and disease. The second is contract manufacturing for the pharmaceutical and specialty-chemical industry: global drug and chemical companies hand PI their recipes, and PI builds the molecules at its own plants and ships them out. So it sits in an unusual spot, serving both the farm and the factory.
The agrochemical side is the older, steadier heart of the business. PI sells to farmers mainly in India, and a big part of its edge comes from the sales force and dealer network that put its brands in front of growers everywhere. It spends on helping farmers understand what to use and when, which builds loyalty and keeps its products on shelves across the country. That reach is hard for rivals to copy quickly. The contract-manufacturing side is the growth engine. Big global chemical and drug companies increasingly don't want to build every plant themselves, and they don't want to risk their secret formulas with just anyone. PI wins this work because it can run complex chemistry to tight quality and environmental standards and keep customers' formulas confidential. These long-term supply deals tend to be sticky — once a customer trusts you with a key molecule, switching is a hassle. The company puts its cash back into expansion. It builds new plants and adds capacity to chase the contract-manufacturing pipeline, and it has spent on acquisitions to widen its chemical reach. For investors, the appeal is the combination: a cash-generating domestic agrochemical business that funds a faster-growing, higher-value export business. The main risks are the ones that come with the sector — weather and farm economics in India, plus global pricing and demand swings in specialty chemicals.
In 1946, a small company called Mewar Oil & General Mills was set up with a simple goal: help India change how it farmed. It made and sold crop-protection chemicals under the VEGFRU brand, and over the following decades it built a countrywide network of dealers and put up its first plant to make the chemicals themselves.
By 1992 the company had been called Pesticide India for a few years, but now it took the name it still wears today: PI Industries. That same year it opened a new factory at Panoli in Gujarat, giving it the identity and the capacity it would need for what came next.
In early January 1993, PI's shares began trading on the Bombay Stock Exchange. This mattered for a simple reason: a growing maker of chemicals needs money, and public markets gave the company a way to raise it from ordinary investors.
Then came a step that looked small at the time. In 1996, PI started making chemicals for other companies, mostly global ones, under what it called Custom Synthesis & Manufacturing — essentially being the hired hands of the chemical world. This export business would grow into one of the company's biggest engines, though few could have guessed it then.
By 2010 the company had a choice to make about who it wanted to be. It sold off its polymer compounding business, a reminder that spreading across many chemical products can leave a company stretched. From here, PI pointed itself squarely at agri-sciences and custom synthesis.
In mid-June 2011, PI listed its shares on the National Stock Exchange as well. That gave it a wider pool of investors and made its stock easier to buy and sell, a small but useful sign of a company now playing on a bigger stage.
PI knew Indian farming and the country's rules inside out, and in 2016 it turned that knowledge into a partnership. It formed a joint venture called Solinnos Agro Sciences with Mitsui Chemicals Agro of Japan to handle the paperwork and registrations needed to bring Japanese agrochemicals into India — Mitsui holding the majority and PI's subsidiary the rest.
The following year PI kept building its domestic brand through global friends. It formed an equal joint venture called PI Kumiai with Japan's Kumiai Chemical to make and sell a rice weedkiller in India, and it also teamed up with BASF to market that company's crop protection products for rice, maize, fruits and vegetables.
In 2024 PI bought PREtec, a move into biopesticides — pest control built on natural, eco-friendly ingredients. This let PI mix biology with its long chemical experience, and it gave the company a cushion against the hard swings of the traditional agrochemical market.
In 2025, Prashant Hegde, the CEO of PI's AgChem Brands, stepped down in November for personal reasons. Jagresh Rana, already the global head of the AgChem business and of biologicals, was named to look after the role as well.
Then the bottom seemed to fall out. After weak quarterly results in 2026, PI's shares crashed more than 16 percent to a 52-week low and were down by more than half over the year. The numbers behind the panic were ugly: profit fell about 70 percent, sales slipped, margins shrank sharply, and exports of agrochemicals were down nearly a fifth under pricing pressure.
The crash forced a bigger question: could PI stop being the hired hand and start owning the ideas? The company is now betting on innovation-led growth, moving away from cost-plus contract manufacturing toward its own research and beyond agriculture. It points to a long research investment of about 200 million dollars with dozens of molecules in development, led by its own insecticide Pioxaniliprole, and it has already launched a home-grown molecule in India — making it the country's first agrochemical innovator with a proven discovery platform. It is also reaching into pharma, specialty chemicals and electronics.
And a quick note: this is PI Industries, not any of the other chemical firms with similar-sounding names out there. It's a genuinely Indian success story in an industry most people never think about, quietly making the chemicals that keep crops alive and drug factories running.

Three customers supply about 68% of PI Industries' contract-drug and farm-chemical manufacturing revenue
PI Industries makes advanced chemicals under long contracts for drug and farm-chemical companies, and this business is the part of the company with the steadiest, most predictable earnings. An estimated 68% of that contract revenue comes from just three multinational accounts. If one of those customers stalls a project or lets a patent expire, the order book feels it later, often before management says anything about it. Source: BIC Research, data from 2026
