FMC Marshal Insecticide (Carbosulfan 25% EC) | Systemic Pest Control
The trusted solution for sucking pests and borers in Rice, Cotton, and Vegetables.
FMC Marshal® is a powerful, broad-spectrum insecticide formulated with Carbosulfan 25% EC. It is designed to provide complete protection against hard-to-kill pests like Brown Plant Hoppers (BPH), Aphids, and Stem Borers.
Unlike ordinary sprays, Marshal works through a unique "Pro-Insecticide" technology. Once applied, it penetrates the plant system and converts into a potent active agent, ensuring that pests hiding inside stems or under leaves are eliminated effectively.
Why Choose This Product? Key Benefits
- ⏱️Double Action Power: Works as both a contact poison (kills on touch) and a stomach poison (kills when eaten), ensuring no pest escapes.
- ?️Systemic Protection: Absorbed by roots and leaves, it moves through the plant's vascular system to kill hidden pests like stem borers.
- ⏳Long-Lasting Control: Stays active within the plant system, providing extended protection against re-infestation of sucking pests.
- ?️Superior Formulation: The high-quality EC formulation ensures better leaf coverage and rain-fastness compared to generic alternatives.
- ?Multi-Crop Versatility: Effective across a wide range of crops including Paddy (Rice), Cotton, Brinjal, Chili, and Cumin.

How It Works: Mode of Action
Marshal attacks the insect's nervous system. It acts as a cholinesterase inhibitor, leading to rapid paralysis and elimination of the pest.
- Rapid Absorption: Upon spraying, the active ingredient Carbosulfan is quickly absorbed by plant tissues and translocated to stems and leaves.
- Metabolic Activation: Once ingested by the pest, the chemical undergoes a metabolic conversion inside the insect, becoming highly potent.
- Nerve Paralysis: It blocks the transmission of nerve signals, causing the insect to stop feeding immediately and die shortly after.
Note: Because it moves inside the plant, it effectively kills sucking pests that hide on the underside of leaves where sprays can't reach.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Brown Plant Hopper (BPH), Green Leaf Hopper, Stem Borer |
| Cotton | Aphids, Thrips, Jassids, Bollworms |
| Vegetables (Chili / Brinjal) | Shoot & Fruit Borer, Aphids, Thrips |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Overdosing may damage crops.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy (Rice) | 320 - 400 ml | 200 L | 2 ml | 14 |
| Cotton | 400 - 500 ml | 200 L | 2 - 2.5 ml | 21 |
| Chili / Brinjal | 350 - 400 ml | 200 L | 2 ml | 7 - 10 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray when pest population crosses the Economic Threshold Level (ETL). Avoid spraying during peak flowering to protect bees.
- Mixing: Fill the spray tank with half water, add the required dose of Marshal, mix well, and fill the remaining water.
- Coverage: Ensure thorough coverage of the foliage. For rice, ensure the spray reaches the base of the stem for BPH control.
- Safety: Always wear PPE (gloves, mask, goggles). This product is toxic by inhalation and ingestion. Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Marshal effective against Brown Plant Hopper (BPH)?
Yes, Marshal is highly effective against BPH in paddy due to its systemic action which reaches the stem base where hoppers feed.
2. Can I use Marshal on export-quality grapes?
No. Residue requirements for export crops are very strict. It is recommended to consult the latest APEDA guidelines before using it on export crops.
3. How soon does it work?
You will see results within 24 hours as the contact action starts immediately, followed by the systemic action.
4. Is it safe for fish?
No. Carbosulfan is toxic to aquatic life. Do not use in fields where fish farming is practiced or near water bodies.
5. What is the difference between Granules and EC?
EC (Liquid) is for foliar spray on leaves. Granules (6% G) are for soil application in standing water (mostly for Rice stem borer). This page describes the Liquid EC.
