Unauthorized HTBt cotton now occupies 30% of India's cotton acreage, with an illicit market value of up to ₹880 crore. This shift is cutting into sales for legitimate seed companies and bypassing biosafety regulations as farmers choose cheaper weed control methods. Investors should watch for potential regulatory crackdowns and the impact on revenue for formal seed manufacturers.
Illegal herbicide-tolerant Bt (HTBt) cotton has expanded to nearly 30% of India's cotton cultivation area, creating a significant disruption for the regulated seed industry. According to the South Asia Biotechnology Centre, this informal sector is now valued between ₹820 crore and ₹880 crore, as farmers increasingly bypass government-approved seed supply chains to manage rising agricultural costs.
The primary driver for this shift is economic. Farmers are choosing these unauthorized seeds to avoid the high expense of manual labor required for weeding. Using glyphosate—the herbicide associated with these seeds—costs roughly ₹750 to ₹850 per acre, compared to over ₹12,000 for manual weeding. This cost advantage has led to a major migration of acreage, particularly in states like Maharashtra, Telangana, and Andhra Pradesh, where adoption rates in some districts have crossed 70%.
For the legitimate seed industry, this surge in illegal trade is a major problem. Sales of authorized Bollgard-II seeds have dropped by over 22% since 2022. Because these unauthorized seeds often contain unapproved traits like the CP4EPSPS herbicide-tolerance gene and the Vip3A insect-resistance gene, they operate entirely outside the biosafety testing framework managed by the government. This creates two distinct risks for formal seed companies: a direct loss of market share and the potential for stricter regulatory clampdowns or policy changes that could further disrupt the legal market.
The rising dependence on glyphosate is also a key factor, with annual consumption in cotton farming jumping 26% to over 35,000 KL. This trend highlights the ongoing struggle between formal seed manufacturers and the informal, cheaper alternatives that are currently capturing the market. Investors following the agriculture and seed sector should track whether the government introduces new regulatory actions to curb this black market, how established companies attempt to recover lost market share, and whether shifts in farm labor costs change the economic incentive for farmers to move back to authorized, compliant seeds.
