Glufosinate ammonium 15% SL (13.5% w/w)

Basta 15 SL is a non-selective, post emergent herbicide recommended for the control of perennial weeds in plantations like tea. The product is very versatile and effective under different climatic conditions. Since Basta 15 SL acts by contact action it is safer to the crops than other non-selective herbicides. It exhibits better efficacy against certain hard-to kill weed species which are not controlled by conventional products currently being used by tea growers.


Glutamine synthetase is the enzyme which catalyses the reaction of ammonia (NH3) and glutamic acid to form glutamine. Ammonia results from nitrate reduction, amino acid metabolism, and photorespiration. Glufosinate-ammonium inhibits the enzyme's activity. This leads to the accumulation of NH3 in the cell. As NH3 is strongly phytotoxic, the affected cells die. This is macroscopically manifested in necrotic spots and finally withering of plant.

Wilting of a treated mixed weed community may start within 24 hours in the tropics, or only after 8 days in cool continental spring or autumn temperatures.


  • Broad-spectrum: Controls broad leaf and grassy weeds
  • Safety: Being primarily contact herbicide, offers relative safety to crop when spray hood is used as compared to the non-selective systemic herbicides.
  • Superior efficacy :Controls 'hard to kill' weeds like Borreria/Fern in tea gardens and other plantation crops.
  • Flexibility:Offers versatile and efficient weed control in variety of row /plantation crops, viz., cotton, chillies, vegetables, grapes, citrus, banana etc.
  • Safe to environment: No residues in soil, water and plant.


Basta 15 SL is to be used @ 2.5 to 3.3 litre per hectare as post emergent herbicide. It is to be applied when weeds are in active vegetative growth stage/flowering stage with a spray shield to prevent drift on the tea plants.
