Verimark® Insecticide (Cyantraniliprole 20% SC)
The Ultimate "Root-Zone Vaccine" for Visibly Vigorous Plants
Verimark® by FMC is a revolutionary soil-applied insecticide designed to protect your crops right from the start. Unlike traditional sprays that only cover leaves, Verimark acts like a vaccine for your plants. Applied to the root zone (via drench or drip), it is absorbed by the roots and moves upward, protecting the tender new growth that pests love to attack.
Best For: Farmers seeking to prevent viral diseases (Leaf Curl) and establish a strong, healthy crop stand in the first critical 30 days.
Why Choose This Product? Key Benefits
- ⏱️Rapid Feeding Cessation: Pests stop eating within minutes of contact. This instant paralysis prevents them from damaging your crop or transmitting deadly viruses.
- ?️Virus Vector Defense: By stopping sucking pests (Whitefly, Thrips) immediately, it breaks the "Green Bridge," drastically reducing the spread of Leaf Curl Virus and Spotted Wilt Virus.
- ⏳Long-Lasting Systemic Action: Moves from the roots to the shoots (Xylem mobile), providing extended protection for up to 3-4 weeks during the critical seedling stage.
- ?️Rainfast Reliability: Because the medicine is inside the plant (absorbed by roots), heavy rains cannot wash it off, unlike foliar sprays.
- ?Visibly Vigorous Plants (VVP): Plants waste less energy fighting stress and pests. The result is greener crops, better root development, and higher marketable yields.

How It Works: Mode of Action
Verimark uses a unique mechanism to stop pests that have become resistant to older chemicals.
- Root Absorption: Applied to the soil, the active ingredient (Cyazypyr®) is drunk by the roots and transported up the plant's water pipes (xylem). [Image of plant xylem transport system]
- Calcium Dump: When an insect ingests the plant juice, the chemical binds to its muscle receptors and forces all stored calcium to be released at once.
- Immediate Paralysis: Without calcium, muscles cannot contract. The insect becomes paralyzed, stops feeding instantly, and dies shortly after.
This works on both chewing pests (caterpillars) and sucking pests (whiteflies/aphids).
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Tomato & Chilli (Peppers) | Whitefly (Vector for Leaf Curl), Thrips, Aphids, Fruit Borer, Leafminer |
| Cucurbits (Cucumber, Melon, Gourd) | Red Pumpkin Beetle, Fruit Fly (suppression), Aphids, Leafminer |
| Onion & Cotton | Onion Maggot, Thrips, Jassids, Whitefly (CLCuV vector) |
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) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Tomato / Chilli / Brinjal | 285 ml | 200 L | ~ 1.5 ml | Refer to Leaflet |
| Cucurbits / Okra | 455 ml | 200 L | ~ 2.25 ml | Refer to Leaflet |
| Onion | 455 ml | 200 L | ~ 2.25 ml | Refer to Leaflet |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Best applied early! Use as a Nursery Tray Drench (3 days before transplanting) or a Soil Drench (10-14 days after transplanting).
- Mixing: Ensure soil moisture is good before application. The solution works best at a neutral to slightly acidic pH (5-6).
- Coverage: For drenching, pour the solution at the base of the plant near the root zone. For drip, inject in the middle of the irrigation cycle.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I spray Verimark on the leaves?
No. Verimark is formulated for root uptake only. Spraying on leaves will result in poor performance. For foliar sprays, use products like Benevia®.
2. What is the difference between Verimark and Coragen?
Coragen is mainly for chewing pests (caterpillars) and is usually sprayed. Verimark controls both sucking and chewing pests and is applied to the soil for systemic action.
3. How does it help with Virus control?
It doesn't kill the virus directly, but it kills the insects (vectors) that carry the virus. By stopping them from feeding instantly, the virus cannot enter the plant.
4. Can I use Verimark in the nursery?
Yes! The "Tray Drench" method 3 days before transplanting is the most efficient and cost-effective way to use Verimark.
5. Is it safe for beneficial insects?
Since it is applied to the soil and not sprayed in the air, it is much safer for bees and beneficial insects compared to foliar sprays.
