Heranba Heraquat is a non-selective contact herbicide containing Paraquat Dichloride 24% SL. It is used for controlling emerged grassy and broadleaf weeds through label-approved directed inter-row, pre-plant or other specified applications.
Heraquat is absorbed mainly through green foliage and acts rapidly on the contacted plant tissue, with some movement through the xylem. Because it is non-selective, spray contact with the green leaves, shoots, bark or other susceptible parts of the main crop can cause serious crop injury.
This product must be applied only to the crops, weeds, timings and doses stated on its current label. Never use it as an unrestricted over-the-top spray on a standing crop.

Heraquat is absorbed by the green foliage of emerged weeds. As a contact herbicide, it damages the plant tissue directly reached by the spray. Uniform foliage coverage is therefore important for satisfactory control.
Paraquat has limited movement compared with a fully systemic herbicide. Established perennial weeds may regrow from roots, rhizomes or other underground structures after the treated foliage is damaged. Repeat spot treatment should be undertaken only where permitted by the current product label.

Conversion caution: These are mathematical conversions only. The current Indian product label is the controlling recommendation and must be followed.
Paraquat is highly hazardous if swallowed and can also cause serious harm through unsafe handling. Keep the product in its original labelled container, locked away from children, food, animal feed and household articles.
If swallowed or exposure is suspected, treat it as a medical emergency. Do not wait for symptoms. Immediately contact a doctor or poison-treatment facility and carry the product container or label. Do not induce vomiting or give anything by mouth unless directed by a medical professional or the product label.
There is no specific antidote stated for paraquat poisoning; treatment is symptomatic and supportive under urgent medical supervision.
Heraquat contains Paraquat Dichloride 24% SL.
No. It is a non-selective contact herbicide and can damage any susceptible green plant tissue reached by the spray.
Generally, no. Standing-crop uses require a carefully directed inter-row spray unless the current label specifically permits another method for that crop.
It acts mainly on contacted foliage and is not a fully systemic root-killing herbicide. Established perennial weeds may regrow from underground roots, rhizomes or tubers.
The supplied recommendations include specified pre-plant minimum-tillage applications. Apply only before sowing or transplanting and strictly according to the current label.
The required quantity depends on the crop and label dose. A 500 ml pack is close to the mathematical acre equivalent of 1.25 litres per hectare, but it is not the correct dose for every crop or use.
Use a tank mixture only when the labels of all products specifically permit it. Do not prepare an unapproved mixture.
No. The attached product is manufactured by Heranba Industries Limited.
