Acephate is an organophosphate insecticide classified under IRAC Group 1B. It inhibits the enzyme acetylcholinesterase in susceptible insects, disrupting normal nerve-function processes and helping control target pests.
| Crop | Target Pest | Recommended Dose |
|---|---|---|
| Cotton | Jassids | 156 g/acre |
| Cotton | Bollworms | 312 g/acre |
| Safflower | Aphids | 312 g/acre |
| Paddy / Rice | Yellow Stem Borer, Leaf Folder, Plant Hoppers, Green Leaf Hopper | 266–400 g/acre |
| Crop | Target Pest | Formulation Dose | Water Volume | Waiting Period |
|---|---|---|---|---|
| Cotton | Jassids | 390 g/ha | 500–1000 L/ha | 15 Days |
| Cotton | Bollworms | 780 g/ha | 500–1000 L/ha | 15 Days |
| Safflower | Aphids | 780 g/ha | 500–1000 L/ha | 15 Days |
| Paddy / Rice | Stem Borer, Leaf Folder, Plant Hoppers, Green Leaf Hopper | 666–1000 g/ha | 300–500 L/ha | 15 Days |
The acre rates listed above correspond with Coromandel's official Ortain recommendations. Water volume should be adjusted according to the registered crop recommendation and spray equipment while maintaining adequate crop coverage.
Acephate belongs to IRAC Group 1B – Organophosphate Acetylcholinesterase Inhibitors. It interferes with acetylcholinesterase activity in the insect nervous system. This disrupts normal nerve-signal regulation in susceptible insects and ultimately results in loss of normal insect function.
Coromandel describes Ortain as providing systemic, contact and ovicidal action, which makes it useful against both sucking and chewing pests included in its registered recommendations.
In cotton, Ortain is recommended for management of jassids and bollworms. The recommended dose differs according to the target pest, so farmers should select the dose based on the actual pest problem rather than using one general cotton rate.
For cotton jassids, Coromandel recommends 156 g per acre, while the recommendation for cotton bollworms is 312 g per acre.
In paddy, Coromandel Ortain is recommended against yellow stem borer, leaf folder, plant hoppers and green leaf hopper. The manufacturer recommends approximately 266–400 g per acre depending on the registered application requirement.
Uniform coverage and timely application during the appropriate pest stage are important for effective insect-management programmes.
For safflower, Ortain is recommended against aphids at approximately 312 g per acre. Apply according to the current product label and ensure adequate crop coverage.
Apply Ortain when the registered target pest is observed and the infestation reaches a level requiring chemical intervention according to local pest-management recommendations.
Early detection and timely treatment generally provide better pest management than delaying application until severe crop damage has occurred.
Coromandel states that Ortain is compatible with commonly available insecticides and fungicides except materials that are highly acidic or highly alkaline.
Even where general compatibility is indicated, a small compatibility test and individual product-label check should be carried out before preparing unfamiliar tank mixtures.
Acephate belongs to IRAC Group 1B. Repeated use of insecticides with the same mode of action can increase selection pressure for resistance in pest populations.
Where multiple insecticide applications are required, integrate Ortain with non-chemical pest-management measures and rotate with appropriately registered insecticides from different IRAC mode-of-action groups.
