Arrow Insecticide (Thiamethoxam 25% WG) – Expert Sucking Pest Control
The "Gold Standard" systemic solution for Rice, Cotton, and Vegetables.
Arrow (Thiamethoxam 25% WG) is a broad-spectrum insecticide designed to protect your crops from damaging sucking pests like Aphids, Jassids, and Brown Plant Hoppers (BPH). Unlike older sprays, Arrow is rapidly absorbed by the plant, traveling through the leaves and roots to build a defense from the inside out.
The "Vigor Effect": Beyond just killing pests, Arrow helps your crop withstand stress, resulting in greener leaves, stronger roots, and better yields.
Why Choose This Product? Key Benefits
-
⏱️
Rapid "Stop-Feed" Action: Pests stop damaging your crop almost immediately after contact or ingestion, preventing further yield loss and virus transmission.
-
🛡️
Dual-Action Armor: It works Systemically (moves up from roots/stem) and Translaminarly (penetrates leaf layers) to kill pests hiding on the undersides of leaves.
-
⏳
Long-Lasting Protection: One application provides protection for weeks, covering new shoot growth that emerges after spraying.
-
🌧️
Rainfast in 2-3 Hours: Quickly absorbed into the plant system, making it resistant to wash-off from rain or irrigation shortly after application.
-
🌿
Phytotonic "Vigor" Effect: Promotes lush greening, improves photosynthesis, and helps plants survive drought and heat stress.

How It Works: Mode of Action
Arrow works by targeting the nervous system of insects. It mimics a natural neurotransmitter but cannot be broken down by the insect's enzymes.
- Uptake: When sprayed, the active ingredient (Thiamethoxam) is absorbed by leaves and roots, entering the plant's sap stream.
- Ingestion: Sucking pests like Aphids and Hoppers pierce the plant to drink sap and ingest the poison.
- Elimination: The chemical permanently blocks nerve signals, causing hyperexcitability and paralysis. The pest stops feeding instantly and dies within 24-48 hours.
Note: Because it moves inside the plant, it effectively kills pests hiding inside curled leaves or at the base of the stem.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Paddy) | Brown Plant Hopper (BPH), Green Leaf Hopper (GLH), Stem Borer |
| Cotton | Jassids, Whiteflies, Aphids, Thrips |
| Vegetables (Okra, Tomato) | Whiteflies, Jassids, Fruit Borer (suppression) |
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 (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice | 40g - 80g | 200 L | 0.2g - 0.4g | 14 Days |
| Cotton | 40g - 80g | 200 L | 0.2g - 0.4g | 21 Days |
| Vegetables (Tomato/Okra) | 40g - 80g | 200 L | 0.2g - 0.4g | 5 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply as soon as you see pests crossing the Economic Threshold Level (e.g., 5-10 hoppers per hill in Rice).
- Mixing: Premix the granules in a small mug of water to form a smooth slurry before adding it to the main spray tank. Do NOT mix with alkaline solutions (like Bordeaux mixture).
- Coverage: Use a "Hollow Cone" nozzle for the best results. Ensure the spray penetrates the canopy to reach the base of the stems (critical for BPH in Rice).
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray during active bee-foraging hours (spray in late evening).
Frequently Asked Questions
1. Is Arrow safe for honeybees?
No, Arrow is toxic to bees. To protect pollinators, apply only in the late evening when bees are not active, especially on flowering crops like Mustard or Mango.
2. Can I mix Arrow with other chemicals?
Yes, it is generally compatible with most neutral insecticides and fungicides (like NPK 19:19:19 or Hexaconazole). Do not mix with highly alkaline products like Lime Sulphur.
3. What is the "Vigor Effect"?
Thiamethoxam stimulates root development and increases chlorophyll. This makes plants look greener and helps them tolerate drought better, even if pest pressure is low.
4. How long does the protection last?
For foliar sprays, protection typically lasts 14 to 21 days. Soil drench applications in crops like Potato can last up to 40-60 days.
5. Is it rainfast?
Yes, Arrow is considered rainfast within 2 to 3 hours after application. Once absorbed by the leaf, rain will not wash it away.
