Gayab Herbicide by Coromandel
A selective atrazine 50% WP herbicide for the listed weeds in maize and sugarcane, with crop-specific early application directions.

Where it fits: Listed grassy and broadleaf weeds in maize and sugarcane.
Timing matters: Coromandel describes application immediately after maize planting or sowing, and pre-emergence use in sugarcane.
Why Choose This Product? Key Benefits
-
🌽Maize weed-control option: The manufacturer lists a specific maize weed spectrum and an early application window.
-
🌱Sugarcane pre-emergence use: Provides a labelled-use option to consider before weed emergence when the current pack covers the treatment.
-
🌾Grass and broadleaf scope: The listed weeds include several grasses and broadleaf species, with different sets for each crop.
-
🧪Defined formulation: Contains atrazine 50% WP rather than a multi-ingredient herbicide mixture.
-
🔬Clear mode-of-action group: HRAC Group 5 identifies atrazine’s photosystem-II action for resistance planning.

How It Works: Mode of Action
Gayab’s active ingredient atrazine inhibits photosynthesis in susceptible weeds. This interferes with the process plants use to turn light into usable chemical energy.
-
Photosystem II is targeted: Atrazine acts at a specific binding site in the photosystem-II complex.
-
Photosynthesis is disrupted: The normal light-driven electron-transfer process is interrupted.
-
Weed growth is affected: Disruption of photosynthesis prevents susceptible weeds from maintaining normal growth. The effect depends on the weed and labelled treatment conditions.
Selectivity does not mean every crop or weed responds the same way. Use appropriate weed-management practices and do not rely on repeated Group 5 herbicide treatments alone.

These are crop-specific weed lists, not a recommendation for every weed or for all crops. Do not move maize directions into sugarcane or extend the product to an unlisted crop.
Dosage & Application Guide
Numerical application programmes are withheld because manufacturer quantities and separate formulation references do not establish complete current Gayab directions, including matching carrier, equipment, soil and moisture conditions and harvest requirements. The manufacturer’s crop-specific early application guidance is retained below.
Historical generic product-and-water references do not establish a complete current Gayab programme. Their harvest intervals are unstated, not zero. The manufacturer booklet also limits the authority of its recommendations and is not the supplied current label.
No numerical product, carrier or tank recipe is supplied here. Confirm the complete matching current-label programme rather than combining rounded manufacturer and generic quantities. A missing numeric waiting period does not mean immediate harvest.
Coromandel describes blanket application immediately after planting or sowing maize, and pre-emergence application in sugarcane. Confirm the corresponding current label directions, including soil and moisture conditions, equipment, repeat limits, following-crop restrictions and re-entry precautions. Do not use a different atrazine mixture’s programme.
How to Apply: Best Practices
-
Confirm the crop and weeds: Match the intended maize or sugarcane use and the weed species to the supplied Gayab label.
-
Keep the crop timing separate: For maize, the manufacturer describes blanket application immediately after planting or sowing; for sugarcane, pre-emergence application. Follow the current pack’s full conditions for that use.
-
Use the label’s mixing and equipment: Follow the WP mixing sequence, water and application-equipment directions. Add another herbicide or adjuvant only when the relevant labels permit the combination.
-
Protect nearby crops and water: Prevent drift and runoff, follow equipment-cleaning and crop-rotation directions, and check current local restrictions and harvest requirements before treatment.
Frequently Asked Questions
What does Gayab contain?
Gayab contains atrazine 50% WP, a selective triazine herbicide in HRAC Group 5.
Which crops does Coromandel list for Gayab?
Maize and sugarcane. Each has its own weed list, product range and timing directions.
Is the application timing identical in both crops?
No. Coromandel describes blanket application immediately after maize planting or sowing, and pre-emergence application in sugarcane. Confirm the current pack’s full directions.
Does “not stated” mean I can harvest immediately?
No. The qualified formulation reference supplies no numeric harvest interval for these rows. Confirm the applicable label and local requirements before treatment.
Can I infer a tank dose from a partial quantity reference?
No separate per-litre or tank rate is given here. Use the current label’s complete product, water, method and area directions rather than deriving a tank rate from partial references.
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.
