treatment.
Preparation and equipment: Water-mixed suspension applied with a knapsack
sprayer.
Why Choose This Product? Key Benefits
-
🌾 Three rice systems listed: Includes
nursery, transplanted and direct-seeded rice without assuming their schedules are interchangeable.
-

barnyard grass, jungle rice and Ischaemum rugosum.
-
🌿 Sedges and other weeds: Includes Cyperus
species and the other named weeds, extending the target list beyond grasses.

How It Works: Mode of Action
-
A growth enzyme is inhibited: Bispyribac-sodium inhibits acetolactate synthase, also called ALS, in susceptible weeds.
-
Essential amino-acid production is limited: ALS is part of the pathway that makes branched-chain amino acids needed for plant
proteins.
-
Normal weed development is disrupted: The interruption of this pathway limits growth and can lead to the death of susceptible
weeds.
This is not an instant contact-burn promise or a fixed time to visible weed death. Other herbicides may also
belong to Group 2; a different brand name alone does not establish a different resistance-management option.

field-water directions must be checked separately for the chosen use. Similar-looking weeds are not automatically
covered.
Dosage & Application Guide
Rice-System Selection & Knapsack Preparation
Select nursery, transplanted or direct-seeded rice correctly before planning treatment. Use the exact crop and
weed-stage window, product amount with its land-area unit, water quantity and harvest restrictions stated on the supplied Oriental
pack together.
Mix the measured product into the specified water, stir well and apply with a knapsack sprayer. Check the
pack’s field-water, coverage and equipment directions before starting; do not invent a drainage period, standing-water depth, spray
concentration or nozzle specification.
How to Apply: Best Practices
-
Identify the rice system: Keep nursery, transplanted and direct-seeded rice directions separate, including any nursery handling or
transplanting restrictions.
-
Match the actual weeds: Confirm the named grasses, sedges and other weeds. Use scientific identities when local names could refer
to more than one species.
-
Check crop and weed stages: Use the current pack’s positive application window. Do not borrow a calendar date or weed-leaf stage
from another bispyribac-sodium brand.
-
Measure the field and calibrate: Set product and water quantities against the labelled treated area. Neither bottle size nor tank
capacity supplies a field rate.
-
Mix and stir as directed: Prepare with water and stir well using suitable equipment, not bare hands. Apply with a knapsack sprayer
and follow its crop-specific setup instructions.
-
Protect neighbouring crops and later field work: Follow weather, drift, re-entry, harvest and further-treatment restrictions.
Resolve any nursery-transfer directions before moving treated plants.
Frequently Asked Questions
1. Can I use one schedule for all three rice systems?
No. Nursery, transplanted and direct-seeded rice are listed separately. Check the exact system’s crop stage,
weed stage, quantities and field-water instructions on the supplied pack.
2. Does Oriental cover only grasses?
No. The named targets include grasses, sedges and other weeds. It does not follow that every weed found in
rice is covered; identify the species and match the target list.
3. Can the SC formulation be sprayed directly from the bottle?
No. It is a suspension concentrate prepared with water. Use the crop-specific product and water quantities,
stir well and apply with a knapsack sprayer.
4. Can I use another bispyribac-sodium product’s timing or tank recipe?
Do not transfer another brand’s programme. Match the current Oriental directions for crop system, target,
area rate, water, timing and restrictions together.
5. Is HRAC Group 2 a toxicity rating?
No. It identifies the herbicide’s ALS-inhibiting mechanism, not a hazard colour or safety rating. Follow the
actual pack’s protective-equipment and handling instructions.
