Which of the following is NOT a bio-pesticide that helps in reducing soil pollution?
Endosulphan
Azadirachta indica
Trichogramma
Bacillus thuringiensis
Endosulphan
Endosulphan is an organochlorine insecticide, not a bio-pesticide. Bio-pesticides are naturally occurring substances or biological agents used to control pests, whereas Endosulphan is a synthetic chemical that causes persistent soil and environmental pollution.
Endosulphan is an organochlorine insecticide, not a bio-pesticide. Bio-pesticides are naturally occurring substances or biological agents used to control pests, whereas Endosulphan is a synthetic chemical that causes persistent soil and environmental pollution.
Using Endosulphan is like using a permanent chemical spill to stop a few ants, whereas bio-pesticides are like introducing a natural predator or a biodegradable herb that solves the problem without leaving toxic garbage behind.
C9тАЛH6тАЛCl6тАЛO3тАЛS тАФ The chemical formula for the organochlorine pesticide Endosulphan.
Endosulphan acts as a neurotoxin by inhibiting the activity of gamma-aminobutyric acid (GABA) receptors and Ca2+-ATPase in the nervous system of insects. Because of its synthetic organochlorine structure, it has a long half-life in soil and exhibits high potential for bioaccumulation in the food chain.
Bio-pesticides are derived from natural materials like animals, plants, bacteria, and certain minerals.
Endosulphan is listed as a Persistent Organic Pollutant (POP) under the Stockholm Convention due to its toxicity and environmental persistence.
Azadirachta indica (Neem) contains Azadirachtin, which disrupts insect growth hormones.
Bacillus thuringiensis (Bt) produces Cry proteins that are lethal specifically to certain insect larvae.
Bio-pesticides are target-specific, causing little to no harm to non-target organisms.
They typically biodegrade quickly and do not leave harmful residues in soil or water.
Synthetic pesticides like Endosulphan are often cheaper and act faster than bio-pesticides.
Bio-pesticides may require more frequent application or specific environmental conditions to be effective.
Integrated Pest Management (IPM) programs.
Organic farming systems to maintain ecological balance.
Endosulphan has been banned in many countries worldwide under the Stockholm Convention on Persistent Organic Pollutants.
Trichogramma is a genus of minute wasps that act as parasitoids, laying eggs inside the eggs of other insects to control their population.
A is correct тАФ Endosulphan is a synthetic organochlorine chemical pesticide, not a bio-pesticide.
Always distinguish between natural biocontrol agents (living organisms) and bio-rational pesticides (natural compounds) versus synthetic, persistent chemicals like organochlorines or organophosphates.
