An in-depth analysis of pesticide consumption patterns and farmer perceptions in Rajasthan's agricultural sector
When Ramesh Singh (name changed), a cotton farmer from Tijara Tehsil in Alwar, Rajasthan, begins his day spraying crops, he carries more than just pesticide tanks on his back. He carries an invisible risk—one that manifests in the recurring headaches he dismisses as part of the job, the skin irritations he considers normal, and the long-term health consequences he rarely considers. Like thousands of farmers across India, Ramesh navigates a daily paradox: using chemicals to secure his harvest while potentially compromising his wellbeing.
Recent studies have confirmed what health experts long suspected: pesticides don't just remain on crops. Research analyzing urine samples found that people who consume produce with higher pesticide levels show significantly elevated pesticide concentrations in their bodies 1 . This revelation connects agricultural practices directly to human health in ways we're only beginning to understand.
In this intricate web of food production, security, and safety, a comprehensive 2019 study conducted in the agricultural region of Tijara Tehsil, Alwar, offers unprecedented insights into why farmers choose certain pesticides, how they use them, and what this means for all of us—from those who grow our food to those who consume it 2 .

Farmers balance crop protection with personal health risks
To understand the reality of pesticide use in Indian agriculture, researchers from MDS University conducted an in-depth investigation in 2019, surveying 500 farmers across Tijara Tehsil in Alwar District, Rajasthan . The study employed a multi-faceted approach including structured questionnaires, face-to-face interviews, focus group discussions, and direct field observations 2 .
This comprehensive methodology allowed researchers to move beyond mere consumption statistics to capture the human dimension of pesticide use—the perceptions, knowledge gaps, and practical realities that shape farmer behavior. The research focused particularly on understanding consumption patterns across different crop types and assessing farmers' awareness of safe handling practices.

Consumption patterns and safety awareness
The findings revealed a clear preference pattern in pesticide use among Alwar farmers. The consumption breakdown showed that insecticides dominated the agricultural landscape, accounting for a substantial 61.11% of all pesticide usage . Herbicides represented 22.22% of the market share, while fungicides accounted for 11.11% .
Among these insecticides, organophosphates emerged as the most frequently used class, followed by newer chemical groups like neonicotinoids and pyrethroids . This trend is particularly concerning as organophosphates have been associated with various health issues in scientific literature, including potential neurological effects 1 .
| Pesticide Type | Percentage Usage | Most Common Classes |
|---|---|---|
| Insecticides | 61.11% | Organophosphates, Neonicotinoids, Pyrethroids |
| Herbicides | 22.22% | Not Specified in Study |
| Fungicides | 11.11% | Not Specified in Study |
| Others | 5.56% | Various |
The variation in pesticide application across different crops proved particularly revealing. The research identified a clear hierarchy of pesticide dependence:
This gradient reflects the economic value and pest vulnerability associated with each crop, with high-value commercial crops like cotton receiving the most intensive chemical protection.
| Crop Type | Percentage of Farmers Using Pesticides | Application Intensity |
|---|---|---|
| Cotton | 93.27% | Very High |
| Vegetables | 87.2% | High |
| Wheat | 66.4% | Medium |
| Millet | 52.6% | Low to Medium |
| Mustard | 12.6% | Low |
Perhaps the most alarming findings from the Alwar study related to farmer behavior and safety practices during pesticide application. Despite handling potentially dangerous chemicals, safety measures were largely neglected by the majority of farmers .
The researchers observed numerous potentially dangerous practices, including farmers smoking and chewing tobacco while spraying pesticides . These activities significantly increase the risk of accidental ingestion and exposure through hand-to-mouth transfer.
Even more concerning was the finding that only 19.4% of farmers utilized protective measures during application 2 . This means approximately 4 out of 5 farmers applied potentially hazardous chemicals without adequate protection, exposing themselves to acute and chronic health risks.
The consequences of these unsafe practices manifested in tangible health outcomes. Nearly half of the respondents (49.8%) reported experiencing immediate health hazards after pesticide application 2 . These acute symptoms likely represent just the visible tip of the iceberg, as pesticide exposure has been linked to far more serious chronic conditions.
The scientific literature connects pesticide exposure to various health issues, including premature births, congenital malformations, spontaneous abortions, and genetic damage in humans 1 . Additional studies have associated pesticides with lower sperm concentrations, heart disease, cancer, and other disorders 1 .
Children are particularly vulnerable to pesticide impacts, with exposure during pregnancy potentially leading to increased risk of birth defects, low birth weight, and fetal death 1 . Childhood exposure has been linked to attention and learning problems, as well as cancer 1 .
One of the most perplexing findings from the Alwar study was the disconnect between knowledge and action. The research revealed that 78.2% of farmers had basic knowledge of safe pesticide handling 2 . Despite this awareness, most continued risky application practices.
This gap between knowledge and practice stems from multiple factors, including the perceived inconvenience of protective equipment, cultural norms, and economic considerations regarding the cost of safety gear. Additionally, there's often a misplaced sense of invulnerability or familiarity bred from years of working with these chemicals without immediately visible consequences.
The implications extend far beyond human health. The study found that 72.8% of farmers discarded pesticide containers directly in their fields 2 . This improper disposal method leads to soil contamination and potential leaching into groundwater systems, creating environmental hazards that persist long after application.
This practice contributes to the broader issue of pesticide persistence in ecosystems, where these chemicals can impact non-target species, including beneficial insects, soil microorganisms, and local wildlife.
As pesticide use continues to be integral to global food production, science offers increasingly sophisticated approaches to mitigate its risks:
Modern analytical methods have become crucial for tracking pesticide contamination. As one study noted, "Liquid chromatographic diode array−mass spectrometric method developed for general screening of pesticide products and quantitative determination" helps identify unexpected contaminants in pesticide formulations 4 . Such methods are vital for ensuring that farmers use products without dangerous impurities.
Research into bio-pesticides—derived from natural materials like plants, bacteria, fungi, or minerals—offers promising alternatives. Recent volatility studies focus on understanding how these eco-friendly options vaporize and disperse after application, enabling the development of formulations that minimize environmental drift 7 .
Innovations like microencapsulation (sealing bioactive agents within protective coatings) and controlled-release carriers can significantly reduce volatilization, while strategic application timing during lower temperatures can cut evaporation rates by 35-60% 7 .
Organizations like the US Environmental Protection Agency (EPA) continuously update safety benchmarks for pesticide compounds. As of September 2025, the EPA maintains 782 chemicals in its Aquatic Life Benchmarks table, regularly adding new pesticides and their degradates for monitoring 5 . Such regulatory oversight is crucial for establishing science-based safety standards.
While scientific advances continue, several practical approaches can immediately reduce risks:
Research shows that properly washing produce can significantly reduce pesticide exposure. The USDA tests that measure pesticide levels use produce washed for 15-20 seconds under running water, mimicking optimal consumer behavior 1 .
"The data we use to estimate pesticide levels comes from washed produce," reminds Alexis Temkin, lead author of the pesticide exposure study. "If you don't wash your produce at home, your exposure would be expected to be higher" 1 .
Consumers can refer to the "Clean Fifteen" and "Dirty Dozen" lists published annually, which identify produce with the least and most pesticide contamination 1 . For instance, recent testing found pineapple to be the least contaminated produce, while spinach contained the highest pesticide levels by weight 1 .

The Alwar study holds a critical lesson that extends far beyond Rajasthan's agricultural lands: there are no completely safe chemicals, only safer ways to use them . As we move forward, the intersection of regulatory oversight, scientific innovation, and farmer education will be crucial for developing sustainable agricultural practices that protect both food security and human health.
The transformation begins with recognizing that the farmer spraying crops in a remote Indian village is connected to the consumer purchasing vegetables in a distant city—and that protecting the health of one ultimately safeguards the wellbeing of both.
