  gained popularity due to their ability to reduce
  surface tension and provide excellent wetting
  properties. They are often used in combination
  with other surfactants to achieve specific
  outcomes.
• Modes of Action
• Aqueous adjuvants work through several
  mechanisms to enhance the effectiveness of
  agrochemicals
• Wetting and Spreading - Aqueous adjuvants
  reduce the surface tension of the spray
  solution, allowing it to spread uniformly
  across plant surfaces. This facilitates
  better contact between the agrochemical and
  the plant, increasing absorption and
  efficacy.
• Penetration - Some adjuvants help
  agrochemicals penetrate plant tissues more
  effectively, ensuring that they reach their
  target sites, such as the phloem or xylem,
  where they can have the desired impact.
• Drift Control - Aqueous adjuvants can reduce
  spray droplet drift, which is crucial for
  minimizing off-target effects and
  environmental contamination. They improve
  the cohesiveness of spray droplets, keeping them
  on target.
• Rainfastness - Adjuvants can enhance the
  rainfastness of agrochemicals, preventing them
  from being washed away by rain shortly after
  application.
