Crystal Arsa Tea Herbicide: Product Overview

Crystal Arsa contains Glufosinate Ammonium 13.5% in an SL formulation. Crystal describes Arsa as a fast-acting, non-selective herbicide for specified weeds in tea.

Because Arsa is non-selective, apply it as a directed treatment to the target weeds. Prevent spray or drift from contacting green tea foliage, nearby crops and other desirable plants. Crystal recommends application when weeds are at the 3-5 leaf stage.

This page is limited to tea because that is the crop shown on Crystal's current Arsa product page. The current physical Crystal Arsa pack and leaflet remain the final authority for every use direction and restriction.

Why farmers choose itWhy Choose Arsa for the Verified Tea Use?
  • Defined tea use: Crystal and the Government sources support a specific tea weed-control scope.
  • Defined weed stage: Crystal recommends application at the 3-5 weed-leaf stage.
  • Official application values: the published formulation rates, water volumes and PHI are retained without creating a universal pump dose.
  • Clear non-selective warning: the content distinguishes directed weed treatment from contact with tea foliage or desirable vegetation.
  • Visible mode-of-action group: Group 10 is stated so a same-group substitute is not mistaken for a different-mode rotation.
Product scienceHow Arsa Works

Glufosinate is classified by HRAC/WSSA in Group 10 and inhibits glutamine synthetase in susceptible weeds. A mode-of-action group supports resistance-management planning, but it does not authorise an unlisted crop, weed, mixture or application timing.

Products with the same active ingredient and Group 10 classification are substitute choices, not different-mode rotation choices. Any alternative herbicide must be selected and applied separately under its own current Indian label. No tank-mix or automatic spray-sequence recommendation is made on this page.

How to applyApplication and Stewardship Guidance
  • Confirm that tea and the target weed appear on the current Arsa pack before application.
  • Target the manufacturer-stated 3-5 weed-leaf stage and use the complete crop-specific formulation rate and water-volume directions.
  • Use directed application and prevent spray or drift from contacting green tea tissue, neighbouring crops, desirable plants and water bodies.
  • Follow the current pack for equipment, mixing order, weather restrictions, maximum applications, re-entry, first aid and disposal. These Arsa-specific details were not verified in the allowed sources.
  • Do not infer tank mixing, simultaneous use or an automatic spray sequence from any Related or Upsell card.
Use with careSafety and Label Compliance
  • Read the current physical Arsa label and leaflet before opening the container. Wear every item of personal protective equipment specified there and avoid inhalation, skin contact and eye contact.
  • Keep the product secured in its original container away from children, animals, food and animal feed. Prevent drift and water contamination.
  • Do not reuse the container. Handle spills, surplus product and empty-container disposal exactly as the label and applicable local rules direct.
  • Do not add product-specific handling, exposure-response or application-restriction details that are not stated on the current physical Arsa pack.
Use with careSafety Disclaimer

Always read and follow the current Crystal Arsa label and leaflet. They are the final authority for crops, weeds, dose, water volume, timing, equipment, PPE, first aid, storage, re-entry, compatibility, disposal and PHI.
