Shanmukha Gassmarr Plus Herbicide (Glufosinate Ammonium 13.5% SL)

Shanmukha Gassmarr Plus Herbicide (Glufosinate Ammonium 13.5% SL)

Shanmukha Gassmarr Plus Herbicide is a broad-spectrum, non-selective, post-emergence contact herbicide containing Glufosinate Ammonium 13.5% SL. It is designed for management of difficult grasses, sedges and broadleaf weeds in registered crops including cotton and tea.

Gassmarr Plus works by inhibiting the enzyme glutamine synthetase in susceptible weeds. For effective control, weeds should be actively growing and receive thorough spray coverage.

Product Specifications

Technical Composition

Glufosinate Ammonium 13.5% SL

Glufosinate Ammonium is a broad-spectrum herbicide that inhibits the plant enzyme glutamine synthetase. This disrupts normal nitrogen metabolism in susceptible weeds and results in rapid injury to treated green plant tissues.

Key Features

• Broad-spectrum non-selective herbicide.
• Post-emergence contact action.
• Contains Glufosinate Ammonium 13.5% SL.
• Useful against difficult-to-control weeds.
• Controls selected grasses, sedges and broadleaf weeds.
• Recommended for cotton and tea according to the official product page.
• Works best when weeds are actively growing.
• Requires thorough coverage of weed foliage.
• Shanmukha recommends a minimum rain-free period after application.

Benefits of Shanmukha Gassmarr Plus

• Broad Weed Spectrum: Controls several important grassy, sedge and broadleaf weeds.
• Post-Emergence Control: Designed for application after target weeds have emerged and are actively growing.
• Tough Weed Management: Shanmukha specifically highlights its usefulness against hard-to-kill weeds.

Recommended Crops, Target Weeds & Dosage

Gassmarr Plus for Cotton

In cotton, Shanmukha recommends Gassmarr Plus against important weeds including Echinochloa species, Cynodon dactylon, Cyperus rotundus, Digitaria marginata and Dactyloctenium aegyptium.

Because Gassmarr Plus is non-selective and contact in action, spray should be directed carefully at the target weeds and contact with desirable green cotton tissue should be avoided unless the current product label specifically permits the application method being used.

Gassmarr Plus for Tea

In tea, Gassmarr Plus is recommended against weeds including Imperata cylindrica, Panicum repens, Borreria hispida, Digitaria sanguinalis, Commelina benghalensis, Ageratum conyzoides, Eleusine indica and Paspalum conjugatum.

Use a directed spray and avoid unwanted contact with green crop tissue because the product is a non-selective herbicide.

Mode of Action

Glufosinate Ammonium inhibits the enzyme glutamine synthetase. This interferes with essential nitrogen metabolism in susceptible weeds and leads to accumulation of toxic levels of ammonia in plant tissues.

As a contact herbicide, effective control depends heavily on adequate spray coverage of actively growing weed foliage.

Best Weed Stage for Application

Shanmukha recommends applying Gassmarr Plus when target weeds are actively growing and approximately 4–6 inches high. Treating weeds at the appropriate growth stage helps improve spray coverage and herbicidal performance.

Rain-Free Period

Maintain a minimum of approximately 6 hours without rainfall after spraying, as recommended by Shanmukha. Rainfall too soon after application may reduce herbicide performance by washing product from treated weed foliage.

How to Use Shanmukha Gassmarr Plus

1. Correctly identify the crop and target weeds.
2. Apply only after weeds have emerged and are actively growing.
3. Measure the recommended quantity according to the cultivated area.
4. Partially fill the spray tank with clean water.
5. Add the measured herbicide and mix thoroughly.
6. Add the remaining required water while maintaining agitation.
7. Apply uniformly to target weed foliage using suitable spraying equipment.
8. Avoid spray drift or direct contact with desirable green crop tissue.
9. Maintain the recommended rain-free period after application.

Application Tips

• Apply when weeds are actively growing.
• Target weeds around the recommended growth stage for better results.
• Ensure adequate and uniform spray coverage.
• Use sufficient spray volume to wet the weed foliage properly.
• Avoid application during strong winds.
• Avoid drift onto neighbouring crops and desirable vegetation.
• Do not spray immediately before expected rainfall.
• Use directed spraying where crop safety requires avoiding green plant tissue.

Important Non-Selective Herbicide Precaution

Gassmarr Plus is a non-selective herbicide. It can damage or kill desirable vegetation if the spray contacts susceptible green plant tissue. Careful directed application and drift management are therefore important.

Do not spray over non-target crops or allow spray droplets to move onto neighbouring vegetation.

Resistance Management

Repeated use of the same herbicidal mode of action can select resistant weed populations. Where repeated weed-control treatments are necessary, combine Gassmarr Plus with appropriate cultural and mechanical weed-management practices and rotate herbicide modes of action according to registered recommendations.

Safety Precautions

• Read the complete product label and leaflet before application.
• Wear suitable gloves, protective clothing, footwear and eye protection while handling and spraying.
• Avoid contact with skin and eyes.
• Avoid inhaling spray mist.
• Do not eat, drink or smoke while handling the herbicide.
• Prevent spray drift onto desirable crops and vegetation.
• Avoid contaminating ponds, streams and other water sources.
• Wash hands, exposed skin and spraying equipment after use.
• Keep the product away from children, animals, food and animal feed.

Q8. How much rain-free time is required after spraying?

The manufacturer recommends a minimum rain-free period of approximately 6 hours.

Q9. How does Glufosinate Ammonium work?

It inhibits the enzyme glutamine synthetase, disrupting nitrogen metabolism in susceptible weeds.

Q10. Can Gassmarr Plus be sprayed directly over the crop canopy?

Do not assume over-the-top crop safety because Gassmarr Plus is non-selective. Follow the current label and use directed application where required to prevent contact with desirable green crop tissue.
