Product details
Officer Herbicide by Coromandel
Bispyribac sodium 20% + pyrazosulfuron ethyl 15% WDG for early post-emergence control of listed weeds in rice. Confirm the current pack dose before treatment.
Crop and stage: Rice, at the early post-emergence stage specified on the current label.
Application route: Foliar spray, not a pre-emergence or late rescue treatment.
Important dose check: The manufacturer marks its published acre dose as under correction. Confirm the supplied label first.
Why Choose This Product? Key Benefits
-
🌾Rice-focused use: Designed for the listed weeds in paddy.
-
🌱Early weed stage: The manufacturer specifies young weeds at an early post-emergence stage.
-
🍃Systemic action: Active ingredients affect growth processes within susceptible weeds.
-
🎯Specified weed coverage: Lists two Echinochloa grasses, Eclipta alba and Cyperus rotundus.
-
🔬Known mode of action: Both ingredients inhibit ALS, the enzyme involved in making essential amino acids.

How It Works: Mode of Action
Officer affects the production of amino acids needed for normal weed growth. Both active ingredients act on the same ALS enzyme pathway.
-
Treatment reaches the weed: Use the manufacturer’s foliar route at the stated young weed stage.
-
Growth processes are blocked: The ingredients inhibit ALS, reducing the weed’s ability to make essential amino acids.
-
Susceptible weeds stop developing normally: Do not assume all weeds or older growth stages will respond in the same way.
Two ingredients do not mean two different resistance groups. Avoid repeated reliance on ALS inhibitors alone and use suitable non-chemical weed-management measures.

Dosage & Application Guide
Numerical application programmes are withheld while the manufacturer’s published quantity remains under correction. A separate government formulation reference does not resolve the current Officer dose or establish a complete matching programme.
The historical generic formulation reference pairs the four listed rice weeds with product, carrier and harvest quantities. These separate references are not a confirmed current Officer programme and must not be used to replace the manufacturer’s unresolved directions.
Coromandel’s current product page explicitly marks its published acre dose as under correction. Obtain the corrected current supplied-label programme before treatment; no product, carrier, harvest or tank recipe is supplied here.
Confirm the exact product quantity, water, harvest interval, re-entry, repeat limits and rain-free period on the current pack. Public manufacturer sources give differing rainfast times, so no fixed rain-free interval is recommended here.
How to Apply: Best Practices
-
Confirm dose and stage: Resolve the complete current programme first. Coromandel specifies early post-emergence treatment of young weeds, not pre-emergence or late post-emergence use.
-
Keep weeds exposed: Use foliar spray on visible weeds in a moist field, not submerged weeds or an excessively dry field. The manufacturer describes a knapsack sprayer with flat-fan, flood-jet or cut nozzle.
-
Manage field water: Coromandel describes refilling the field after treatment and maintaining water and adequate moisture. Confirm the exact refill delay, depth and retention period as part of the corrected current programme; do not drain treated water into another field.
-
Keep treatment separate: The manufacturer does not recommend mixing Officer with other products. Follow the pack’s protective-equipment, harvest and field-entry directions.
Frequently Asked Questions
What is Officer’s composition?
Bispyribac sodium 20% + pyrazosulfuron ethyl 15% in water-dispersible granules.
When is Officer intended for use?
Early after weeds emerge, with the exact weed stage confirmed as part of the corrected current programme. It is not a pre-emergence treatment or a general late-stage rescue spray.
Why is the numerical programme withheld?
The manufacturer flags its published acre dose as under correction. A different generic formulation quantity cannot resolve that correction; obtain the complete current supplied-label programme before treatment.
Can I mix it with another pesticide?
Coromandel does not recommend mixing Officer with other products. Do not assume a tank partner is suitable.
Does it use two different resistance groups?
No. Both ingredients act through ALS inhibition in HRAC Group 2. Plan rotations by mode of action, not only by brand name.
Safety & Disclaimer
Before you use it, read the supplied label and leaflet. Use only for the stated crop, target, dose, application conditions, waiting periods and precautions. Check current local restrictions and any buyer requirements for harvested produce.
Wear the protective clothing and equipment specified on the pack. Avoid breathing dust or spray and avoid contact with skin and eyes. Do not eat, drink or smoke while handling; wash after work.
Keep the product in its original closed container, away from children, animals, food and feed. Prevent spray, spills and washings from contaminating water bodies. Do not reuse empty containers. If exposure or illness occurs, seek medical help and show the label.
