⏱️
Double Action Power: Works via both Contact (direct hit) and Systemic action (absorbed by the plant) to kill pests hiding on the underside of leaves.
-
🛡️
Complete Solubility: The Soluble Powder (SP) formulation dissolves 100% in water without leaving residue, ensuring no nozzle clogging and accurate dosing.
-
⏳
Long-Lasting Protection: Once absorbed, it stays active inside the plant system, protecting new growth from pests for several days.
-
🌧️
Rain Fastness: Rapidly absorbed by leaves, making it effective even if it rains a few hours after spraying.
-
🌿
Crop Safe: Free from harsh organic solvents (like Xylene found in ECs), reducing the risk of leaf burn or phytotoxicity.

How It Works: Mode of Action
Oval works by targeting the nervous system of the insect. It is an Acetylcholinesterase (AChE) inhibitor.
- Systemic Entry: When sprayed, Acephate is absorbed by the leaves and moves upward (acropetally) through the plant's system.
- Ingestion: Sucking pests feed on the plant sap containing the chemical, and chewing pests eat the treated leaves.
- Paralysis & Elimination: The active ingredient disrupts the nerve signals in the insect, leading to paralysis, cessation of feeding, and death.
Note: It also has "Ovicidal" action, meaning it can help control insect eggs.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Jassids (Leafhoppers), Bollworms |
| Safflower | Aphids |
| Rice (Paddy) | Stem Borer, Leaf Folder, Plant Hoppers (BPH/GLH) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Using water volume based on crop canopy size is essential.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Approx. Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton (Jassids) | 156 g | 200 L | 0.75 g | 15 |
| Cotton (Bollworms) | 312 g | 200 L | 1.5 - 2 g | 15 |
| Safflower | 312 g | 200 L | 1.5 - 2 g | 15 |
| Rice | 270 - 400 g | 150 - 200 L | 1.5 - 2 g | 15 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply when pest population crosses the Economic Threshold Level (ETL). For Jassids, this is usually 2 nymphs per leaf.
- Mixing: Do NOT mix Oval with alkaline chemicals like Bordeaux mixture or Lime Sulfur, as this destroys the chemical effectiveness. It is compatible with Hexaconazole or Mancozeb.
- Coverage: Ensure thorough coverage of the plant canopy. The systemic action helps, but good coverage improves results.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray during peak bee foraging hours.
Frequently Asked Questions
1. Does Oval kill insect eggs?
Yes, Oval has ovicidal properties, meaning it can destroy eggs and early-instar larvae of pests like Bollworms.
2. Can I mix Oval with fungicides?
Yes, Oval is generally compatible with common fungicides like Hexaconazole, Mancozeb, and Carbendazim. Avoid mixing with alkaline products.
3. Is Oval safe for bees?
Acephate is toxic to bees. Avoid spraying during flowering stages or spray in the late evening when bees are not active.
4. What is the waiting period before harvest?
You should wait at least 15 days after spraying Oval before harvesting Cotton, Rice, or Safflower.
5. Why is the dose higher for Bollworms?
Chewing pests like Bollworms have a larger body mass and higher metabolism than tiny sucking pests, requiring a stronger dose (312g/acre) for effective control.
