paraquat

[หˆparษ™หŒkwรคt ]

Definition

Context #1 | Noun

chemical compound

Paraquat is a highly toxic chemical used as a herbicide, primarily for the control of grass and broadleaf weeds. It is known for its effectiveness in agricultural applications, particularly for crops such as cotton and soybeans. Paraquat works by causing rapid cell death in plants, leading to their destruction. However, due to its toxicity, it poses significant health risks to humans and animals if ingested or inhaled. As a result, many countries have imposed strict regulations or bans on its use.

Synonyms

herbicide, weed killer.

Examples of usage

  • Farmers apply paraquat to control weed growth.
  • The use of paraquat is regulated in many countries.
  • Accidental exposure to paraquat can be fatal.
  • Some crops are resistant to paraquat.

Origin of 'paraquat'

The word 'paraquat' is derived from the chemical name 'paraquat dichloride,' which is a bipyridyl herbicide. The name originates from 'para-' referring to the specific configuration of molecular structure, and 'quat' short for 'quaternary ammonium compound.' Paraquat was first introduced in the 1960s and has since been extensively used in agriculture due to its rapid action against weeds. Its development marks a significant milestone in agricultural chemistry, aiming to increase crop yields by providing an effective means to eliminate unwanted plants. Despite its advantages in farming, the dangers associated with paraquat exposure have led to increased scrutiny and regulatory actions globally, with many countries recognizing the need for careful handling and use of such toxic substances.
