How It Works: Mode of Action
Cosayr works through a unique method called Ryanodine Receptor Activation. Here is the simple three-step process of how it eliminates threats:
- Ingestion & Absorption: The insect eats the treated leaves or absorbs the chemical through its skin.
- Muscle Paralysis: The active ingredient specifically targets the insect's calcium channels, causing its muscles to contract uncontrollably until it is completely paralyzed.
- Starvation & Death: Because they are paralyzed, pests stop feeding instantly and die from starvation and dehydration within 1 to 3 days.

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Paddy) | 60 | 150 - 250 | 0.3 - 0.4 | 35 - 40 |
| Sugarcane | 150 | 200 - 400+ | ~0.4 - 0.7 | Refer to label |
| Vegetables (Tomato, Cabbage) | 60 - 100 | 150 - 250 | 0.3 - 0.4 | 1 Day |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply precisely when pest eggs are hatching or when early-stage larvae are first spotted. Early interception prevents damage entirely.
- Mixing: Fill your spray tank halfway with water, add the required dose of Cosayr while stirring, and use a non-ionic surfactant for the best spread across leaves.
- Coverage: Ensure complete and even coverage of the entire plant canopy. The solution needs to reach the undersides of leaves where pests often hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Cosayr safe for honeybees?
Yes! Cosayr is highly selective and practically harmless to foraging pollinators like honeybees, making it an excellent choice during blooming seasons.
2. Can I use it if I grow silkworms nearby?
No. Cosayr is extremely deadly to silkworms. You must never spray it on or let it drift near mulberry plantations.
3. How soon can workers return to the field after spraying?
The Restricted Entry Interval (REI) is very short—just 12 hours, or simply once the spray liquid has completely dried on the crop.
4. What happens if it rains after I spray?
If Cosayr is given at least 2 hours to dry on the plant, it becomes highly rainfast and will not wash off during heavy rain or irrigation.
5. How often can I spray Cosayr in one season?
To prevent pests from becoming resistant, you should apply it a maximum of two times within a 30-day window. Always rotate with different chemical classes afterward.
