leaves.
Why Choose This Product? Key Benefits
-
🌱 Early weed control: Treats the listed
weeds after emergence while they are small.
-
🌾 Rice programme: Targets listed sedges and
broadleaf weeds in transplanted rice, with weed-specific stage checks.
-
🫘 Soybean use: Targets the listed broadleaf
weeds and purple nutsedge in soybean.
-
🍃 Contact activity: Acts on the weed foliage
reached by the spray, making coverage important.
-
🔆 Stops photosynthesis: Bentazone blocks a
key energy-producing process in susceptible weeds.

How It Works: Mode of Action
Basagran is a selective contact herbicide. Bentazone inhibits
photosystem II in susceptible weeds.
-
Contact the foliage: Spray reaches the exposed leaves of the target weeds.
-
Block photosynthesis: Bentazone interrupts electron transport in photosystem II.
-
Stop weed growth: Loss of normal energy production leads to growth arrest and death of susceptible weeds.
Coverage and weed stage matter. Do not treat this as an
all-purpose grass herbicide or assume that every weed species is controlled.

Dosage & Application Guide
The complete rows below apply only to these broadleaf targets: soybean, Acalypha indica and Commelina
benghalensis; transplanted rice, Ludwigia spp. and Eclipta alba. They do not provide a complete sedge-treatment schedule or a
direct-seeded-rice programme.

Sedge references, not a complete schedule: For soybean purple nutsedge (Cyperus rotundus), the
manufacturer’s overview gives 800 ml/acre and 200 L water/acre. A separate soybean water reference is 500 L/ha (approximately 202
L/acre); do not silently substitute it into that overview. For transplanted-rice variable flatsedge (Cyperus difformis), the leaflet
references are 2,000 ml/ha (approximately 809 ml/acre) and 500 L/ha (approximately 202 L/acre). Retain the crop harvest safeguards: 62
days for soybean and 71 days for transplanted rice. These facts do not complete a sedge-treatment schedule. Obtain the supplied pack’s
exact weed-stage instructions before treatment; do not assume that a 2–3-inch height and a 2–3-leaf stage are
interchangeable.
Acre figures are approximate conversions of the original leaflet hectare quantities. The manufacturer’s
overview separately states 800 ml/acre in 200 L/acre; do not combine or silently substitute these rounded references. Use the complete
directions on the supplied pack for your crop and target. No fixed per-litre or tank dose is supplied.
PHI is the minimum time from the final treatment to harvest. Harvest, worker re-entry and repeat-treatment
restrictions are separate; do not assume a missing interval is zero. Measure the area rather than improvising a pump
recipe.
How to Apply: Best Practices
-
Weed stage: For the broadleaf targets named above, apply early post-emergence at 2–3 leaves. Obtain the supplied pack’s separate
sedge-stage directions before treating sedges.
-
Rice water management: Drain standing water so weed foliage is exposed. BASF directs re-irrigation of rice 24–48 hours after
treatment.
-
Sprayer and coverage: Use a knapsack sprayer fitted with a flat-fan nozzle. Cover weed foliage thoroughly with the required water
volume.
-
Mixing partners: Do not add another herbicide, pesticide, fertilizer or adjuvant unless both current product labels permit the
specific combination for the crop and method.
-
Harvest: Leave at least 62 days before soybean harvest and 71 days before transplanted-rice harvest.
Do not substitute another brand, concentration or overseas directions. Follow the pack’s weather precautions
and rain-free period; do not assume a fixed rainfast interval. Record the crop, field, date and product amount, and observe all
harvest, worker-entry and repeat restrictions before the next operation.
Frequently Asked Questions
When should Basagran be applied?
For the named broadleaf targets, apply early post-emergence at 2–3 leaves. Sedge treatment requires the
supplied pack’s separate stage instructions; do not substitute height for leaf count.
Must standing water be removed from rice?
Yes. Expose weed leaves for contact and thorough coverage. BASF directs re-irrigation after 24–48 hours.
Does Basagran control every grass weed?
No blanket grass-control claim is made here. Use it for the specific crop and weed targets listed, and
follow the supplied label.
What are the harvest intervals?
The BASF leaflet specifies 62 days for soybean and 71 days for transplanted rice.
Can I use the same dose for a 15-litre tank?
A fixed tank dose is not supplied. Use the product quantity for the measured area and enough of the
specified water to cover the weed foliage.

follow supplied disposal directions.
Remove contaminated clothing immediately. After skin contact, wash thoroughly with soap and plenty of
