In India, the use of carbofuran, methyl parathion, phorate and triazophos is viewed with apprehension. These chemicals are used as

Result
Your answer: β€”  Β·  Correct: A
Explanation

The correct answer is option A because carbofuran, along with other similar formulations, are being used as pesticides (PPC) in India[2], and bans for methyl parathion, phorate and triazophos have been announced by the Central Government in 2018 and 2020[5]. The apprehension mentioned in the question stems from the fact that pesticides are noted contaminants and are defined as harmful to human health[2]. Additionally, Methyl Parathion formulations are banned for use on fruits and vegetables[7], indicating their classification as agricultural pesticides. The fact that carbofuran remains among the nine pesticides banned in Kerala but still in use nationally with no plans for regulatory action[8] further underscores the concern around these chemicals as agricultural pesticides rather than food preservatives, fruit-ripening agents, or cosmetic ingredients.

The gas caused internal haemorrhage, lung failure and death. Worst affected were the inhabitants of the villages and slums in the neighbouring areas of the factory.”
Why relevant

Describes a catastrophic release from a pesticide plant (methyl isocyanate), highlighting that pesticide chemicals and their manufacture are regulated and associated with toxicity incidents.

How to extend

Use this to reinforce that pesticide-related chemicals are treated as hazardous industrial compounds rather than cosmetic emollients; follow up by checking regulatory/prohibited ingredient lists for cosmetics in India.

Pattern takeaway: UPSC follows a 'Chemicals in News' pattern: List of 3-4 obscure names -> Identify the application. (e.g., Triclosan -> Toiletries; Cas9 -> Gene Editing). The context 'viewed with apprehension' is a massive hint pointing towards toxicity/regulation.
How you should have studied
  1. [THE VERDICT]: Sitter. If you have read any standard chapter on 'Environmental Pollution' or 'Agriculture', Carbofuran and Phorate are frequently cited examples of hazardous agrochemicals.
  2. [THE CONCEPTUAL TRIGGER]: Agriculture > Inputs > Plant Protection. Specifically, the theme of 'Negative Impacts of Green Revolution' and pesticide toxicity (Organophosphates/Carbamates).
  3. [THE HORIZONTAL EXPANSION]: Memorize the 'Dirty Dozen' and recent news-makers: Endosulfan (Supreme Court ban), Monocrotophos (highly toxic), Glyphosate (herbicide controversy), Diclofenac (vultures), and Malathion (locust control). Know the difference between Insecticides, Herbicides, and Rodenticides.
  4. [THE STRATEGIC METACOGNITION]: When you see a list of complex chemical names in UPSC, apply the 'One-Match Rule'. Do not panic if you don't know 'Triazophos'. If you know 'Carbofuran' is a pesticide, the entire list must be pesticides. Study lists of banned items by category, not individually.

πŸ‘‰ Purpose of food processing includes preservation
πŸ’‘ The insight

Food processing is explicitly used to preserve food items and extend availability, which is the functional role of preservatives in processed foods.

Core concept for food industry and supply-chain questions: explains why preservatives (or preservation methods) are used, connects to food safety regulation (FSSAI) and export promotion, and aids answering questions on processed-food policy and storage technologies.

πŸ‘‰ Pesticide bans and regulated agrochemicals in India
πŸ’‘ The insight

Knowledge of which agrochemicals are banned is directly relevant to evaluating claims about their use as fruit-ripening agents.

High-yield for environment and agriculture topics: helps answer questions on public health, regulatory frameworks, and banned substances. Connects to policy, trade restrictions, and food safety debates; enables elimination-style reasoning in MCQs about permitted versus prohibited chemicals.

πŸŒ‘ The Hidden Trap

Since they asked about Insecticides here, the next logical target is Herbicides (Weedicides). Watch out for 'Glyphosate', 'Atrazine', and 'Butachlor'. Also, check the 'Stockholm Convention' list of Persistent Organic Pollutants (POPs) like Mirex and Heptachlor.

⚑ Elimination Cheat Code

The 'Suffix Hack': Chemical names ending in '-phos' (Phorate, Triazophos) usually indicate Organophosphates (Phosphorus-based). Names ending in '-furan' or '-thion' are typical of synthetic agrochemicals. Conversely, food preservatives usually have friendly names like 'Benzoates', 'Sorbates', or 'Sulphites'. If the names sound like chemical warfare agents, mark 'Pesticides'.

πŸ”— Mains Connection

Connect this to GS-3 (Agriculture & Food Security) and GS-2 (Health). Excessive pesticide use leads to 'Cancer Trains' (Punjab case study) and rejection of Indian export consignments (Basmati rice issues due to Tricyclazole residues). This justifies the push for Organic Farming (PKVY).
