Shapat - Sodium Acifluorfen 16.5% + Clodinafop-Propargyl 8% EC - Parijat
Shapat Soybean Herbicide by Parijat
Sodium Acifluorfen 16.5% + Clodinafop-Propargyl 8% EC for listed grass and broadleaf weeds in
soybean.
Crop and target: Soybean, with a specific mixed list of grasses and broadleaf
weeds.
Treatment window: 15–25 days after sowing, when weeds are at the 2–4-leaf stage;
only one use in a crop.
Application safeguards: Sufficient soil moisture, a knapsack sprayer with flat-fan
or flood-jet nozzle, and uniform coverage without overlap.
Why Choose This Product? Key Benefits
-
🌿 Mixed grass and broadleaf scope: The
soybean target list includes grasses and broadleaf weeds, rather than only one weed group.
-
🧩 Two different herbicide mechanisms: Acifluorfen and clodinafop-propargyl affect different biochemical processes in susceptible weeds.
-
🌱 Defined post-emergence window: Crop age
and weed leaf stage are considered together, instead of treating any emerged weed as suitable.
-
🚿 No spreader or booster required: The
product directions do not require either addition; an extra additive is not automatically beneficial or permitted.

How It Works: Mode of Action
-
Acifluorfen affects the PPO pathway: Group 14 activity disrupts a plant pigment-production pathway, leading to damage to
susceptible weed-cell membranes.
-
Clodinafop interrupts fatty-acid production: Group 1 activity inhibits ACCase, an enzyme needed for the fatty acids that support
grass-weed growth and new cell structures.
-
Membrane injury and growth disruption combine: The two actions contribute to decline of susceptible weeds, explaining the mixed
grass-and-broadleaf purpose.
Two mechanisms do not guarantee control of resistant or unlisted weeds, an exact kill time or freedom from crop
injury. Consider both HRAC groups and the one-use-per-crop restriction when planning weed management.

Identify the weeds in the soybean field before treatment. Genus-level entries do not establish control of every
species, and this soybean list is not permission to spray another crop or neighbouring vegetation.
Dosage & Application Guide
Soybean at 15–25 Days & Weeds at 2–4 Leaves
Apply as a post-emergence foliar spray 15–25 days after sowing, when weeds are at the 2–4-leaf stage, within
the complete soybean pack directions. Both conditions matter. Use only once in a crop, with sufficient soil moisture and a knapsack
sprayer fitted with a flat-fan or flood-jet nozzle.
Before measuring, confirm the product amount, treated area, water and harvest interval together. Mix the
specified product into a bucket half-filled with water, mix well, then add the remaining specified water. Spray uniformly without
overlap. No spreader or booster is required; do not add another product unless both current labels permit the combination for the crop
and use.
How to Apply: Best Practices
-
Identify the weeds and soybean stage: Match the listed weeds and check both 15–25 days after sowing and the weeds’ 2–4-leaf stage.
Do not extend the window to older weeds by increasing the quantity.
-
Plan one treatment in the crop: The stated limit is one use per crop. Record the application and do not turn surviving weeds or
crop symptoms into an automatic repeat.
-
Check soil moisture and weather: Ensure sufficient soil moisture and do not spray in foggy conditions. Follow the pack’s wind
restrictions and avoid conditions that could carry spray into adjoining crops.
-
Prepare the stated spray setup: Use a knapsack sprayer with a flat-fan or flood-jet nozzle. Inspect and calibrate it for the
treated area rather than assuming a fixed area per tank.
-
Mix and place evenly: Add the measured product to a bucket half-filled with water, mix well, then add the remaining specified
water. Use suitable mixing equipment, not bare hands. Spray in the wind direction without overlap while preventing drift into adjoining
crop fields.
-
Assess crop response and later work: Leaf bronzing can occur after treatment, but do not assume every crop symptom is harmless or
certain to recover. Seek qualified advice if concerned, and follow harvest, re-entry and following-crop restrictions.
Frequently Asked Questions
1. What does the application window mean?
Use 15–25 days after sowing when the weeds are at the 2–4-leaf stage. These are paired crop-age and
weed-stage conditions, not two independent options. Follow the complete soybean directions before treatment.
2. Can I spray again if weeds survive?
The stated restriction is only one use in a crop. Check weed identity, timing and coverage and seek
crop-specific advice rather than repeating Shapat or increasing the quantity.
3. Does Shapat need a spreader or booster?
No spreader or booster is required in the product directions. Do not add one merely to intensify treatment.
Any proposed combination must be permitted by both current labels for the crop and use.
4. What if soybean leaves become bronze?
Leaf bronzing is a described crop response, but that does not prove that every injury is harmless or will
recover. Do not increase the rate or repeat treatment in response; check the pack and seek qualified advice about the symptoms.
5. What spray equipment and field conditions matter?
Use a knapsack sprayer with a flat-fan or flood-jet nozzle, sufficient soil moisture and uniform coverage
without overlap. Avoid foggy weather, spray in the wind direction within the pack’s weather restrictions, and keep drift out of
adjoining crops.
Safety & Disclaimer
Before you use it: Read the current Shapat label and leaflet before use, including the full soybean
quantity and harvest directions, protective equipment, weather, re-entry, first-aid, storage and disposal precautions. Keep the
stated stage window and one-use-per-crop restriction.
Wear the stated gloves, apron, mask and other required equipment. Do not mix with bare hands; avoid mouth,
eye and skin contact and inhaling spray mist, fog or vapour. Do not eat, drink, smoke or chew while handling or spraying, and wash
thoroughly afterwards. Maintain soil moisture, avoid foggy weather and prevent overlap and drift into adjoining
crops.
Store in the original labelled container away from water, fire, food, feed, children and animals. Prevent
contamination of water sources. Seek medical help after exposure or illness and take the pack or label; no specific antidote is
known, and a clinician should provide symptomatic treatment. No universal crop-safety, rainfastness, following-crop safety or
recovery guarantee is implied.
