Glufosinate Ammonium 13.5% SL

Glufosinate Ammonium 13.5% SL

Glufosinate Ammonium 13.5% SL is a broad-spectrum, non-selective contact herbicide derived from naturally occurring compounds produced by Streptomyces soil bacteria. Widely trusted by cotton and tea farmers across India, it offers fast, reliable control of tough annual and perennial grasses and broadleaf weeds that prove difficult to manage with other herbicides, including many weeds that have developed resistance to glyphosate.

How Glufosinate Ammonium 13.5% SL Works

This herbicide works by irreversibly inhibiting the glutamine synthetase enzyme inside weed plant cells — a unique mode of action that separates it from most other herbicides available today. When this enzyme is blocked, the plant can no longer process the toxic ammonia it naturally produces during metabolism. This ammonia rapidly builds up inside the weed’s cells, disrupting photosynthesis and breaking down cell membranes. The result is fast desiccation and death of all treated green tissue, with initial symptoms visible within just 2 to 4 days of spraying and complete weed death within 7 to 10 days.

Why Farmers Choose This Herbicide

One of the most important advantages of Glufosinate Ammonium 13.5% SL is its effectiveness against hard-to-kill weeds like Cynodon dactylon (doob grass), Cyperus rotundus (Motha), Imperata cylindrica (kans grass), and Eleusine indica that often escape or resist other herbicide treatments. Because it works through a completely different biochemical pathway compared to glyphosate and other common herbicides, it remains fully effective even against weed populations that have developed resistance to those products — making it a critical tool for resistance management in integrated weed control programs.

Unlike glyphosate, which is a fully systemic herbicide, Glufosinate Ammonium acts primarily through contact action with some limited systemic movement. This means thorough spray coverage of all weed foliage is important for best results. The product leaves no soil residual activity and does not persist in the environment, making it safe for both the soil and surrounding ecosystem. Many farmers in cotton and tea growing regions also value the speed of visible results, which appear within days rather than weeks, giving quick confirmation that the treatment is working.

Key Benefits

• Controls tough grasses and broadleaf weeds including Cynodon, Cyperus, and Imperata
• Effective against glyphosate-resistant weed populations
• Unique mode of action — valuable tool for resistance management
• Fast visible results — weed symptoms within 2 to 4 days
• No soil residual activity — safe for environment and future crops
• Derived from natural soil bacteria — lower environmental impact
• Can also provide some protection against fungal and bacterial diseases on contact

Why Crop Nutrition Matters After Weed Control

After clearing weeds and giving the crop full access to nutrients and sunlight, strong nutritional support helps maximize that advantage. Products like Humic Acid 98% Flakes improve soil health and root development during early crop growth, while Power PGR Liquid supports better flowering and fruit development as the crop matures toward harvest.

Safety Tips & Precautions

• Use only as a directed spray on target weeds — non-selective, avoid contact with crop foliage
• Spray when weeds are actively growing at 4 to 6 inch height for best results
• Minimum 6 hour rain-free period required after spraying
• Wear gloves, mask, and protective clothing while mixing and applying
• Avoid drift onto nearby crops or desirable plants
• Wash hands and skin thoroughly after use; keep away from children and animals

Storage Instructions

Store Glufosinate Ammonium 13.5% SL in a cool, dry place away from direct sunlight and moisture. Keep tightly sealed in the original container and out of reach of children and animals.
