Fil Industries Filquat is a highly effective contact herbicide formulated with Paraquat Dichloride 24% SL, known for its rapid desiccation action on green plant tissue. It is widely used for controlling emerged weeds in field crops, orchards, plantation systems, and non-cropped areas where quick weed clearance is required.

Filquat works by rapidly disrupting the photosynthetic system of plants, leading to immediate cell membrane damage and dehydration of weed foliage. Since it is a contact herbicide, it acts only on the green parts it touches, delivering visible results within hours of application under active growth conditions.

It is an important tool in pre-plant and inter-row weed management programs, helping farmers maintain clean field conditions, reduce crop-weed competition, and improve nutrient availability for the main crop.

Technical Details

Product Type:
Non-Selective Contact Herbicide

Technical Composition:
Paraquat Dichloride 24% SL

Formulation:
Soluble Liquid (SL)

---

Mode of Action

Paraquat acts by interfering with the photosystem I electron transport chain, generating reactive oxygen species that rapidly destroy cell membranes, leading to desiccation and death of green plant tissues.

---

Mode of Entry

Contact action only (no translocation within plant system)

---

Recommendations (Crops | Target Weeds | Dosage | Dilution)

Orchards | Annual grasses & broadleaf weeds | As per label | 1–2 L/ha in 200–300 L water

Plantations | Mixed weed flora | As per label | 1–2 L/ha

Non-crop areas | General weed control | As per label | Field spray dilution

Pre-plant applications | Existing weed burn-down | As per label | Uniform foliar spray

---

PHI & REI (Safety Intervals)

PHI (Pre-Harvest Interval):
Not applicable (used for weed control; avoid application on standing edible crop foliage)

REI (Re-Entry Interval):
24–48 hours after application or once sprayed surface is completely dry

---

Application Method

Apply as a post-emergence foliar spray on actively growing weeds using a knapsack or boom sprayer. Ensure uniform coverage of weed foliage for effective burn-down action. Avoid spray drift onto desirable crops due to non-selective nature.
