Show answer
Answer: (A) pesticides in agriculture
The correct answer is (A) — pesticides in agriculture.
Carbofuran, methyl parathion, phorate, and triazophos are all chemical pesticides (specifically insecticides) used in Indian agriculture.
They are highly toxic and their overuse raises concerns about:
- soil contamination
- water pollution
- health risks to farmers and consumers
They are NOT:
- food preservatives
- fruit-ripening agents
- cosmetic ingredients
Tip: If you see chemical names ending in '-furan', '-thion', '-phos' in a UPSC question, think pesticides.
These four chemicals are highly toxic pesticides that cause serious soil and water contamination in Indian agriculture.
UPSC is testing pattern recognition - chemical names ending in '-furan', '-thion', and '-phos' are typically pesticides, not food or cosmetic additives.

Toxic Pesticides in Indian Agriculture: Environmental & Health Concerns
Carbofuran, methyl parathion, phorate, triazophos are highly toxic insecticides used in Indian agriculture
These chemicals cause soil contamination, water pollution and pose serious health risks to farmers
Chemical names ending in -furan, -thion, -phos typically indicate pesticide compounds
Why These Chemicals Matter
These four chemicals represent India's most problematic pesticides — highly effective against pests but extremely toxic to humans and the environment. Their widespread use in Indian agriculture has created a pollution crisis that UPSC frequently tests.
Key Toxic Pesticides
Pesticide | Chemical Type | Primary Use | Major Concern |
|---|---|---|---|
Carbofuran | Carbamate insecticide | Soil application for root pests | Groundwater contamination |
Methyl Parathion | Organophosphate | Foliar spray on crops | Acute poisoning in farmers |
Phorate | Organophosphate | Systemic soil insecticide | Bioaccumulation in food chain |
Triazophos | Organophosphate | Contact & systemic action | Residue persistence in soil |
Environmental Impact
Soil contamination: Persist in soil for months, killing beneficial microorganisms
Water pollution: Leach into groundwater and contaminate drinking sources
Bioaccumulation: Build up in food chain, affecting birds and aquatic life
Resistance development: Overuse leads to pesticide-resistant pest strains
Question Context
UPSC tested recognition of these specific pesticides by name. The question's phrase 'viewed with apprehension' was the key hint — these chemicals are controversial due to their toxicity, not because they're used in food, cosmetics, or fruit ripening.
Trap: Options B, C, D sound plausible but these chemicals are too toxic for food/cosmetic use
Memory aid: Chemical endings -furan, -thion, -phos = pesticides, not preservatives
The word 'apprehension' indicates environmental/health concerns, pointing to agricultural chemicals
Pesticide Classification & Types
Environment pesticides
Pesticide Classification: Chemical Types & Mechanisms
Organophosphates are the most common but toxic pesticides affecting nervous system
Carbamates work similarly to organophosphates but break down faster in environment
Systemic pesticides are absorbed by plants, contact pesticides kill on direct touch
Major Pesticide Categories
Chemical Class | Mechanism | Toxicity Level | Examples | Environmental Fate |
|---|---|---|---|---|
Organophosphates | Inhibit acetylcholinesterase enzyme | Very High | Methyl parathion, Phorate, Triazophos | Moderate persistence |
Carbamates | Inhibit acetylcholinesterase (reversible) | High | Carbofuran, Carbaryl | Break down faster |
Organochlorines | Disrupt nervous system | Moderate | DDT (banned), Endosulfan | Very persistent |
Pyrethroids | Target sodium channels in nerves | Lower | Cypermethrin, Deltamethrin | Degrade quickly |
Pesticide Classification
# Pesticides
## By Target
- Insecticides
- Herbicides
- Fungicides
- Rodenticides
## By Action
- Systemic
- Contact
- Stomach poison
- Fumigants
## By Chemistry
- Organophosphates
- Carbamates
- Pyrethroids
- NeonicotinoidsDon't confuse organophosphates (pesticides) with organochlorines (mostly banned)
Systemic vs Contact: Systemic = absorbed by plant, Contact = kills on touch
Bio-pesticides (neem, Bt) are different from chemical pesticides — eco-friendly alternatives
Agricultural Pollution in India
Environment
Agricultural Pollution Crisis in India: Causes & Consequences
Punjab, Haryana, UP have highest pesticide use due to intensive Green Revolution farming
India uses banned pesticides still legal here but prohibited in manufacturing countries
Cotton and rice crops consume 60% of India's pesticides despite covering 25% of area
Root Causes
India's agricultural pollution stems from intensive farming practices adopted during the Green Revolution. Farmers use excessive pesticides due to lack of awareness, easy availability, and immediate pest control results, creating a chemical dependency cycle.
Major Pollution Sources
Pesticide overuse: 3x higher application rates than recommended doses
Chemical fertilizers: Nitrogen runoff causing eutrophication in water bodies
Crop residue burning: Stubble burning in North India creating air pollution
Plastic mulching: Non-biodegradable film polluting agricultural soil
State-wise Pesticide Consumption
State/Region | Pesticide Use Level | Main Crops | Primary Concern |
|---|---|---|---|
Punjab | Very High | Wheat, Rice | Cancer cases in Malwa region |
Maharashtra | High | Cotton, Sugarcane | Farmer suicides linked to costs |
Andhra Pradesh | High | Cotton, Chili | Groundwater contamination |
Kerala | Moderate | Spices, Coconut | Endosulfan tragedy in Kasargod |
Government Initiatives
National Mission on Sustainable Agriculture: Promoting organic farming and IPM
Pesticide ban list: Gradually banning highly toxic chemicals like Endosulfan
Paramparagat Krishi Vikas Yojana: Financial support for organic farming clusters
Green Revolution increased productivity but also created pollution — dual impact
Don't assume all agricultural chemicals are banned — many toxic ones still legal in India
IPM = Integrated Pest Management, not Indian Pest Management
Food Preservatives & Alternatives
Science And Technology preservatives processed foods
Food Preservatives: Types, Safety & Regulation
Chemical preservatives like sodium benzoate, potassium sorbate are safe for food use
Pesticide chemicals are never used as food preservatives due to extreme toxicity
FSSAI regulates food additives and sets maximum permissible limits
Why Not Pesticides
The question's incorrect options included food preservatives. Pesticides like carbofuran are never used in food because they're designed to kill living organisms and would be lethal to humans even in tiny amounts.
Common Food Preservatives
Preservative | Chemical Name | Food Use | Safety Level |
|---|---|---|---|
Sodium Benzoate | E211 | Soft drinks, pickles | GRAS (Generally Recognized as Safe) |
Potassium Sorbate | E202 | Cheese, wine, baked goods | Very safe, naturally occurring |
Calcium Propionate | E282 | Bread, dairy products | Safe, inhibits mold growth |
Sulfur Dioxide | E220 | Dried fruits, wine | Safe in limits, can cause allergies |
Natural vs Synthetic
Natural preservatives: Salt, sugar, vinegar, citric acid, vitamin E
Synthetic preservatives: More effective, longer shelf life, cost-effective
Antioxidants: BHA, BHT prevent rancidity in fats and oils
Antimicrobials: Prevent bacterial and fungal growth in processed foods
Never confuse agricultural pesticides with food preservatives — completely different safety profiles
E-numbers (E211, E202) are European codes for food additives, not pesticide codes
Natural doesn't always mean safer — botulism from improper preservation is deadly
