FMC Verimark® Insecticide (Cyantraniliprole 20% SC)
The Ultimate "Vaccine" for Crops: Premium Soil-Applied Systemic Protection against Sucking and Chewing Pests.
FMC Verimark® is a revolutionary soil-applied insecticide powered by the active ingredient Cyantraniliprole (Cyazypyr®). Unlike traditional sprays that only cover the leaves, Verimark is designed to be absorbed by the roots. It travels up through the plant's vascular system, creating a "protected zone" from the inside out.
Best for: Protecting high-value crops like Tomato, Chilli, and Cotton during the critical early stages (seedling to vegetative). It ensures "Visibly Vigorous Plants" (VVP) by stopping pests before they transmit deadly viruses.

-
⏱️
Stops Feeding Instantly: Pests stop eating within minutes of ingestion. This "Rapid Feeding Cessation" prevents them from transmitting viruses like Leaf Curl.
-
🛡️
Systemic Root-to-Shoot Defense: Applied to the soil (drip or drench), it moves upward to protect new growth and tender leaves where pests attack first.
-
⏳
Visibly Vigorous Plants (VVP): By saving the plant's energy from stress and repair, Verimark leads to better root establishment, earlier flowering, and higher yields.
-
🌧️
Rainfast & Durable: Because the medicine is inside the plant tissue, it cannot be washed away by rain or irrigation.
-
🌿
Green Label Safety: Classified as a "Green Label" product in India, it offers low toxicity to humans and is safe for applicators when used correctly.

How It Works: Mode of Action
Verimark targets the insect's muscle system with precision. It acts as a Ryanodine Receptor (RyR) modulator.
- Uptake: The active ingredient is absorbed by plant roots and moves up to the leaves.
- Calcium Depletion: When a pest feeds, the chemical binds to their muscle receptors, forcing an uncontrolled release of Calcium ($Ca^{2+}$).
- Paralysis: This depletes the insect's calcium stores, causing immediate muscle paralysis. The insect stops feeding and dies, unable to damage the crop further.
Note: This mechanism works on both sucking pests (like Whitefly) and chewing pests (like Caterpillars).
Target Crops & Pests
[Image of whitefly damage on tomato leaf]| Crop | Target Pest(s) |
|---|---|
| Tomato & Chilli (Peppers) | Whitefly (ToLCV Vector), Aphids, Thrips, Fruit Borer (Helicoverpa), Leafminer |
| Cucurbits (Cucumber, Melon, Gourd) | Whitefly, Red Pumpkin Beetle, Aphids, Leafminer, Melonworm |
| Cotton & Onion | Whitefly, Jassids, Thrips, Onion Maggot |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Verimark is strictly for Soil Application (Drench or Drip), not foliar spray.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Method | PHI (Days) |
|---|---|---|---|---|
| Tomato & Chilli | 280 - 300 ml | 200 L (Drench) | Soil Drench / Drip | 3-5 |
| Cucurbits / Melons | 450 ml | 200 L | Soil Drench | 3-5 |
| Onion | 450 ml | Variable | Drench / Drip | 7 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Dose calculation based on 700-1125 ml/hectare recommendations.
How to Apply: Best Practices
- Timing: For best results, apply early (seedling stage). Tray drench 3 days before transplanting, or soil drench 10-14 days after transplanting (DAT).
- Mixing: Ensure the water pH is between 4 and 6. Shake the bottle well before measuring.
- Coverage: The soil should be moist before application to help the roots absorb the chemical effectively. If using drip, inject in the middle 1/3 of the cycle.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I use Verimark as a foliar spray on leaves?
No. Verimark is specifically formulated for soil application (roots). For foliar spraying, you should use FMC Benevia®.
2. What is the difference between Coragen and Verimark?
Coragen controls mostly caterpillars (Lepidoptera). Verimark controls a broader spectrum, including tough sucking pests like Whiteflies and Thrips, along with caterpillars.
3. How many times can I apply Verimark in one season?
Do not apply more than once per crop season. This helps prevent pests from developing resistance to the chemical.
4. Does Verimark kill earthworms?
Verimark has low toxicity to earthworms and soil microorganisms when used at recommended doses, making it compatible with sustainable farming.
5. Is it rainfast?
Yes. Since Verimark is absorbed into the plant system via roots, it is highly rainfast once uptake has occurred.
