Explanation:

  • Endosulfan is a synthetic pesticide and is NOT a bio-pesticide. It is an organochlorine compound that has been widely used as an agricultural insecticide but is highly toxic and persistent in the environment, leading to significant soil pollution and health concerns. Due to its harmful effects, it has been banned or restricted in many countries.

  • Bacillus thuringiensis (Bt): This is a bacterium that produces toxins harmful to certain insects. It is widely used as a bio-pesticide because it targets specific pests without causing harm to other organisms or the environment.

  • Trichogramma: These are parasitic wasps that lay their eggs in the eggs of pest insects. They are used as a biological control agent to reduce the population of harmful pests.

  • Azadirachta indica: Commonly known as neem, this plant produces natural compounds that act as bio-pesticides. Neem-based products are used to manage a variety of pests in an environmentally friendly way.
