Dhavak - Glufosinate Ammonium 13.5% w/w SL - HPM

HPM Dhavak Herbicide: Product Overview

HPM Dhavak contains Glufosinate Ammonium 13.5% w/w in an SL formulation, equivalent to 15% w/v in the Government of India major-use entry. It is a non-selective post-emergence herbicide registered for specified weeds in tea and cotton.

Glufosinate works mainly through treated green weed tissue, so accurate coverage is important. Because Dhavak is non-selective, spray or drift can injure tea foliage, cotton plants and other desirable vegetation. Use a directed application to the target weeds and follow the current physical pack for the exact timing, equipment, re-entry period, protective clothing and all handling directions.

This page keeps the registered hectare rates and water volumes. It does not convert them into a universal pump or per-litre dose, and it does not advertise non-crop use, guaranteed performance in all weather, control of glyphosate-resistant weeds, a toxicity colour or a fixed time to visible symptoms without Dhavak-specific label evidence.

Why Choose HPM Dhavak?

• Defined Indian uses: the official major-use table lists Glufosinate Ammonium 13.5% SL for specified weeds in tea and cotton.
• Broad registered weed spectrum: the label entries cover important grasses, broadleaf weeds and sedges.
• Non-selective post-emergence action: the product targets emerged weeds through green tissue when applied as a carefully directed spray.
• Resistance-management clarity: glufosinate is HRAC/WSSA Group 10, a different mode of action from Group 9 glyphosate products.
• Practical catalogue packs: Mana Agri Mart lists 250 ml, 500 ml and 1 L variants. Choose a pack only after calculating the registered treatment area.

Technical Specifications

How Glufosinate Group 10 Works

Glufosinate inhibits glutamine synthetase in susceptible weeds. This disrupts nitrogen metabolism and causes ammonia accumulation, leading to loss of photosynthetic function and damage to treated tissue. Adequate coverage of green weed foliage is important because movement within the plant is limited compared with highly systemic herbicides.

A mode-of-action group supports resistance planning, but it does not prove that a weed population is resistant or that one product will replace another at the same dose. Avoid repeated reliance on HRAC Group 10 alone. Combine label-compliant chemical use with cultural or mechanical weed management where practical. Any separately chosen rotation product must have its own current Indian label for the crop, weed and timing.

Registered Weeds, Dose, Water Volume and PHI

PHI = pre-harvest interval. These Government of India values are per hectare. Do not replace them with a universal pump, tank or per-litre dose.

Application Guidance

• Identify the crop and weed species, then confirm both on the current physical Dhavak label before measuring the product.
• Apply as a directed post-emergence foliar spray to actively growing weeds. Prevent spray and drift from contacting tea foliage, cotton plants, nearby crops and other desirable vegetation.
• Use the registered formulation rate and water volume for the treatment area. Do not extrapolate one crop's directions to the other crop.
• Use clean water and follow the physical label for mixing order, nozzle, equipment, spray timing, maximum applications and re-entry. These Dhavak-specific details were not independently verified here.
• Avoid application when wind could cause drift or rain could wash the spray away. Keep spray, rinsate and empty containers away from ponds, aquaculture and other water bodies.
• No tank-mix or compatibility recommendation is made. Related and rotation products are standalone purchase alternatives, not co-application instructions.

Frequently Asked Questions

Which crops are registered for Dhavak here?
The verified formulation-level major-use table lists tea and cotton. This page does not advertise non-crop or additional crop uses without Dhavak-specific label confirmation.

What is the registered Dhavak dose for tea?
2.5–3.3 L formulation/ha in 375–500 L water/ha, with a 15-day PHI.

What is the registered dose for cotton?
2.5–3.0 L formulation/ha in 500 L water/ha, with a 96-day PHI.

Can Dhavak be sprayed directly over tea or cotton foliage?
No. It is non-selective. Direct the spray to the target weeds and prevent contact with desirable green tissue.

How soon will weeds show symptoms?
Speed varies with species, growth stage, coverage and weather. No universal 3–5 day promise is made; follow the current label and assess control over the label-directed period.

Can Dhavak be tank-mixed with another herbicide?
No universal compatibility or tank-mix claim is made. Apply any separately selected product only under its own current Indian label.

What is the re-entry interval?
A Dhavak-specific numeric interval was not verified from the allowed sources. Follow the current physical pack and do not publish or rely on a guessed value.

Safety and Disclaimer

Always read and follow the current HPM Dhavak label and leaflet. They are the final authority for registered crops and weeds, dose, water volume, timing, equipment, PPE, first aid, storage, re-entry, disposal and PHI. Wear every item of protective equipment stated there, avoid inhalation and skin or eye contact, and store the original container away from children, animals, food and feed.
