FMC Marshal® Insecticide (Carbosulfan 25% EC)
The Ultimate Systemic Solution for Sucking Pests and Stem Borers.
FMC Marshal® is a trusted, broad-spectrum insecticide designed to protect your crops from tough pests. Powered by Carbosulfan, it works through a unique "double action" mechanism—killing pests on contact and through stomach ingestion. Its systemic nature allows it to penetrate the plant, eliminating hidden insects like stem borers and leaf folders that surface sprays often miss.

How It Works: Mode of Action
Marshal® operates as a cholinesterase inhibitor. It disrupts the nervous system of the insect, leading to paralysis and elimination.
- Contact & Stomach Poison: Pests die if they touch the spray or eat treated leaves.
- Systemic Translocation: The chemical is absorbed by roots and leaves, moving through the plant's vascular system to reach hidden pests like borers.
- Bio-Activation: Once inside the pest, it converts into a highly potent active form, ensuring a lethal blow to resistant insects.
Note: Because of its systemic nature, it is highly effective against sucking pests that feed on plant sap.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Paddy) | Brown Plant Hopper (BPH), Stem Borer, Green Leaf Hopper, Gall Midge |
| Cotton | Aphids, Thrips, Jassids, Whiteflies, Bollworms |
| Chili & Vegetables | Thrips, Aphids, Fruit & Shoot Borer, Diamond Back Moth (DBM) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Overdosing can burn the plant; under-dosing leads to resistance.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 400 - 500 ml | 200 Litres | 2.0 - 2.5 ml | Refer to Label |
| Rice (Paddy) | 320 - 400 ml | 200 Litres | 1.5 - 2.0 ml | Refer to Label |
| Chili / Brinjal | 400 ml | 200 Litres | 2.0 ml | Refer to Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Strictly observe PHI to ensure food safety.
How to Apply: Best Practices
- Timing: Apply when pest population reaches the Economic Threshold Level (ETL)—basically, when you see active pests.
- Mixing: Add the required quantity of Marshal® to a small amount of water, mix well, and then add to the main tank.
- Coverage: Ensure thorough coverage of the foliage, especially the undersides of leaves where aphids and thrips hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray during strong winds.
Frequently Asked Questions
1. Does Marshal® kill stem borers?
Yes. Marshal® is systemic, meaning it enters the plant stem and kills larvae (borers) that are feeding inside.
2. What is the active ingredient in FMC Marshal?
The active ingredient is Carbosulfan 25% EC. It acts as a pro-insecticide that converts to a potent form inside the pest.
3. Is it safe for honeybees?
No. Marshal® is toxic to bees. Avoid spraying during the active flowering stage of the crop to protect pollinators.
4. Can I mix Marshal with other fungicides?
Generally, yes. However, always perform a physical compatibility test (jar test) before mixing large quantities.
5. What is the antidote for accidental poisoning?
The antidote is Atropine Sulphate. In case of ingestion or severe exposure, seek immediate medical attention and show the container label to the doctor.
