What is

Glufosinate is a broad-spectrum, non-selective contact herbicide that is used to control a wide range of weeds after the crop emerges or for total vegetation control.


does it work?

Glufosinate is a natural compound isolated from two species of Streptomyces fungi. It inhibits the activity of an enzyme, glutamine synthase (GS), which is necessary for the production of glutamine and for ammonia detoxification.

  • In plants, glutamate combines with ammonia (NH3), with the help of an enzyme glutamine synthase (GS), to form the essential plant amino acid, glutamine.
  • Glufosinate, a glutamate look-alike, binds irreversibly to the enzyme glutamine synthase (GS), blocking the formation of glutamine, the essential amino acid. This prevents ammonia detoxification.
  • The free ammonia (NH3) quickly builds up to toxic levels because it is no longer being used up in glutamine synthase and the weed can no longer survive. Thus, the compound functions as an active herbicide.


UPL Glufosinate?


Segments/ usages of Glufosinate


Pre-planting / Directed post-planting application in numerous crops as per country regulatory approvals.

UPL Glufosinate can be very efficiently used as pre-sowing burn down in various field crops with no worry of side-effects on subsequent crop. Glufosinate can be used very efficiently in minimum till or no-till cropping system.

Vines & Orchards:

UPL Glufosinate can be used very safely in vines and orchards where the vines and trees have stems which are completely lignified. Caution is advised during usage in young trees and vines so as to minimize the drift as well as direct exposure on the crop.

Over the Top treatment:

Over the top treatment with UPL Glufosinate can be used only in crops genetically modified for in-built resistance to Glufosinate.


Tank mix with residual Herbicides:

Glufosinate can be tank mixed very well with various residual herbicides.
For example: UPI Tricor




for use


  1. Non Selective Herbicides, only directed spray – on weeds, avoid drift on the host crop as much as possible.
  2. Use 'Over the top' application for GA tolerant crops only.
  3. Use recommended dose based on time and type of weeds.
  4. Use clean water for spray.
  5. Use flat fan / flood jet nozzle.
  6. Use only when weeds are in an actively growing stage;
    4-6 inches high.
  7. There has to be minimum 6 hours rain free period after spraying.
  8. Clean sprayer tank, hose and nozzle before and after use.
  9. Follow all precautions while handling Agrochemicals.


  1. Do not spray /allow drift on main crop.
  2. Do not use muddy / saline water for spray.
  3. Do not use hollow cone nozzle and avoid power sprayer for spraying.
  4. Do not recommend spray in water-stressed condition.
  5. No tall claims on duration or spectrum of control are being made by us.
  6. Spraying before emergence of weeds is not recommended.
