insecticide is a type of chemical or natural medicine that is used to kill or control harmful insects that attack crops. Insects like aphids, caterpillars, whiteflies, beetles, and grasshoppers eat plant parts (leaves, stems, fruits) or suck their juices. This weakens the plant and reduces the harvest.

Examples of Insecticides:

  • Chlorpyrifos (used for soil insects and termites)

  • Imidacloprid (used for sucking insects like aphids and whiteflies)

  • Cypermethrin (used for chewing insects like caterpillars)

Insecticides help farmers control insect attacks in several ways:

  1. Kill Insects Quickly

  • Insecticides can kill insects either when they touch it (contact action) or when they eat the treated plant (stomach action).

  • Some insecticides are also absorbed by the plant and kill insects that suck the plant sap (systemic action).

  1. Stop Insect Growth and Reproduction

  • Some insecticides interfere with the insect's life cycle.

  • They prevent young insects (larvae) from growing into adults, and adults from laying eggs.

  • This reduces the future insect population.

  1. Repel Insects

  • Some insecticides don't kill but keep insects away from the plants.

  • This reduces feeding damage and infection.

  1. Protect Entire Fields

  • By controlling insects early, farmers can stop the spread of pest outbreaks across the whole farm.
