ICAR, FCI sign MoU to tackle wheat and rice storage pests sustainably
Synopsis
Key Takeaways
The Indian Council of Agricultural Research (ICAR) and the Food Corporation of India (FCI) have signed a memorandum of understanding (MoU) to research alternative fumigation technologies for the safe and sustainable management of storage pests in wheat and rice, according to an official statement released on Thursday, 1 October 2026. The collaboration is backed by the Department of Food & Public Distribution (DFPD) under the Ministry of Consumer Affairs, Food & Public Distribution.
The Problem With Current Fumigation Methods
India's strategic grain reserves have long depended on aluminium phosphide (ALP) and malathion for post-harvest pest control. However, repeated and widespread use of these chemicals has produced severe consequences. According to the official statement, pest resistance frequencies have reached 72–100 per cent in key Indian states, forcing ever-escalating fumigation cycles that drive up operational costs. Beyond economics, current chemical methods reportedly pose significant respiratory hazards to workers and carry long-term ecological risks — including concerns over fumigant residues in stored grain.
What the MoU Proposes
The partnership aims to standardise the commercial use of three alternative approaches: nitrogen gas, carbon dioxide (CO2), and a synergistic combination of CO2 and phosphine. The initiative is designed to develop scientifically validated, scalable, and sustainable replacements for conventional chemical fumigation, directly addressing pest resistance, occupational exposure, and environmental impact.
Phase-I Trials: Three Parallel Tracks
Phase-I will run for two years and will be implemented by ICAR–Central Institute of Post-Harvest Engineering and Technology (CIPHET) in Ludhiana. Three major trials are planned:
First, nitrogen gas (above 99 per cent purity) fumigation will be tested for managing storage pests in wheat held in metal silos. Second, a combined carbon dioxide and phosphine treatment will be evaluated for pest control in wheat and rice stored in bags at FCI and Central Warehousing Corporation (CWC) warehouses. Third, carbon dioxide fumigation alone will be assessed for wheat and rice stored in bags enclosed in hermetic covers.
Phase-II and the Road Ahead
Following the Phase-I pilot, a one-year Phase-II multi-location trial will expand testing across varied agro-climatic zones across India. The goal is to establish region-specific Standard Operating Procedures (SOPs) that can be adopted at scale by government grain storage agencies. Notably, this is among the first structured, government-backed efforts to move India's post-harvest pest management away from chemical dependency toward controlled-atmosphere alternatives — a shift that grain storage experts have advocated for over a decade.
