Sumil Chemicals Nasht Herbicide (Glufosinate Ammonium 13.5% SL)

Non-Selective Post-Emergence Herbicide for Broad-Spectrum Weed Control

Sumil Chemicals Nasht Herbicide (Glufosinate Ammonium 13.5% SL) is a broad-spectrum, non-selective post-emergence herbicide designed for the management of actively growing grassy weeds, broadleaf weeds and certain sedges. It is suitable for directed weed-control applications in label-recommended crops such as cotton and tea.

Nasht acts mainly through treated green weed tissues and provides relatively rapid visible weed suppression. Glufosinate Ammonium inhibits an important enzyme involved in plant nitrogen metabolism, resulting in ammonia accumulation, disruption of photosynthesis and progressive drying of susceptible weeds.

Key Features of Sumil Chemicals Nasht

• Broad-Spectrum Weed Management: Helps control a range of grassy weeds, broadleaf weeds and certain sedges.
• Non-Selective Action: Controls susceptible green vegetation contacted by the spray.
• Post-Emergence Herbicide: Applied after target weeds have emerged and are actively growing.
• Quick Visible Action: Susceptible weeds gradually show yellowing, browning and drying after treatment.
• Useful for Difficult Weeds: Helps manage persistent weeds such as Bermuda grass and nutgrass where listed on the label.
• Directed Application: Suitable for carefully directed or hooded spraying to keep the herbicide away from crop foliage.

Dosage and Application

Use the current Nasht product label as the final authority for crop-specific dose, spray volume, weed stage and application instructions.

Mode of Action

Glufosinate Ammonium inhibits the plant enzyme glutamine synthetase, which plays an important role in nitrogen metabolism.

After application to susceptible weeds, inhibition of this enzyme results in accumulation of ammonia within plant tissues. This disrupts photosynthesis and other essential physiological processes, causing growth to stop followed by chlorosis, browning and drying of treated vegetation.

Contact-Like Weed Control

Glufosinate primarily acts within green tissues that receive adequate spray coverage. Movement throughout the entire weed is limited compared with highly systemic herbicides.

For this reason, thorough and uniform coverage of target weed foliage is important for good performance.

Nasht for Grass Weed Control

Nasht can help control several difficult grassy weeds in label-recommended crops, including species such as Cynodon dactylon, Dactyloctenium aegyptium, Digitaria species and other susceptible grasses.

Application to young and actively growing weeds generally provides better results than treatment of old, mature or severely stressed weeds.

Nasht for Cyperus Rotundus

Cyperus rotundus, commonly known as nutgrass or motha, is a persistent sedge that can compete strongly with crops for nutrients, moisture and growing space.

Glufosinate Ammonium 13.5% SL has label-recommended activity against Cyperus rotundus in cotton. Good coverage of actively growing foliage is important, and repeated integrated weed-management practices may be required where underground tubers cause fresh emergence.

Nasht for Broadleaf Weeds

The product also provides activity against susceptible broadleaf weeds in label-recommended situations. Because it is a broad-spectrum non-selective herbicide, it should be directed only toward target weeds and kept away from green crop tissue.

Nasht for Cotton

In cotton, Glufosinate Ammonium 13.5% SL is used as a directed or hooded post-emergence spray against target weeds growing between crop rows.

The herbicide should not be allowed to contact green cotton leaves, tender stems or other actively growing crop tissues because non-selective herbicidal action can cause crop injury.

Nasht for Tea

In tea plantations, Nasht can be used for directed weed management against label-recommended grasses and broadleaf weeds.

Spray should be carefully targeted at weed vegetation while avoiding contact with green tea foliage, shoots and other desirable plants.

Best Time to Apply

Apply Nasht when weeds are young, emerged and actively growing. Good growing conditions generally improve herbicide uptake and weed response.

Avoid application to severely drought-stressed, dusty, old or mature weeds where possible, as such conditions may reduce performance.

How to Use Sumil Chemicals Nasht

1. Identify the crop and target weed species before spraying.
2. Confirm that the intended crop and weeds are listed on the current product label.
3. Measure the recommended quantity accurately.
4. Partially fill the spray tank with clean water.
5. Add the measured quantity of Nasht while maintaining agitation.
6. Add the remaining water and mix thoroughly.
7. Use a suitable flat-fan or other label-recommended herbicide nozzle.
8. Direct the spray uniformly over actively growing target weeds.
9. Prevent spray contact with crop foliage and other desirable vegetation.
10. Avoid excessive overlapping of spray passes.

Directed and Hooded Spray Application

Since Nasht is a non-selective herbicide, a directed or hooded spray is important when weeds are growing close to crop plants.

The spray shield helps restrict droplets to the weed area and reduces accidental contact with green crop tissue.

Application Tips

• Spray actively growing weeds.
• Ensure complete and uniform weed coverage.
• Use the crop-specific label dose.
• Use properly calibrated spraying equipment.
• Use a directed or hooded spray where crop foliage is nearby.
• Avoid spraying during strong winds.
• Avoid spray drift onto neighbouring crops.
• Do not spray immediately before expected rainfall.
• Do not exceed the recommended application rate.

Important Crop Safety Information

Nasht contains a non-selective herbicide. It can damage desirable plants when spray droplets contact actively growing green tissues.

• Do not broadcast spray over conventional cotton or tea foliage.
• Keep spray away from tender stems, leaves and shoots.
• Use shields or hoods where necessary.
• Avoid spray drift onto adjacent crops.
• Clean spraying equipment thoroughly after herbicide application.

Herbicide Stewardship

Repeated dependence on a single herbicide mode of action can increase selection pressure on weed populations. Nasht should therefore be integrated with suitable agronomic weed-management practices.

Where practical, combine chemical weed management with cultivation, mulching, crop competition, field sanitation and suitable herbicide rotation according to crop recommendations.

Safety Precautions

• Wear gloves, protective clothing, eye protection and suitable footwear during mixing and spraying.
• Avoid direct contact with skin and eyes.
• Avoid inhaling spray mist.
• Do not eat, drink or smoke while handling the herbicide.
• Wash hands and exposed skin thoroughly after application.
• Keep away from children, animals, food and animal feed.
• Prevent contamination of wells, ponds, canals and other water bodies.
• Do not allow spray drift onto non-target plants.
