Zumba Herbicide (Fomesafen 11.1% + Fluazifop-P-butyl 11.1% SL)
The Ultimate "Dual-Action" Weed Specialist for Soybean & Groundnut.
Weeds compete with your crop for sunlight, water, and nutrients, potentially reducing yields by 30% to 80% if left unchecked. Zumba is a technologically advanced, ready-mix post-emergence herbicide designed to solve this problem.
Zumba combines two powerful active ingredients—Fomesafen and Fluazifop-P-butyl—to deliver complete control over both grassy and broadleaf weeds in a single spray. Manufactured by Krishi Rasayan Exports Pvt. Ltd. (KREPL), it ensures your crop stays weed-free during the critical growth period.
Why Choose This Product? Key Benefits
-
⏱️
Fast Visual Results:
Experience rapid action. Weeds stop growing almost immediately, with visible drying and control appearing within days. -
🛡️
Dual-Action Power:
Why buy two products? Zumba controls tough grasses (like Echinochloa) and stubborn broadleaves (like Trianthema) simultaneously. -
⏳
Excellent Rainfastness:
Perfect for the monsoon season. Zumba becomes rainfast in just 1 hour, ensuring your money isn't washed away by sudden showers. -
🌧️
Advanced Formulation:
The Soluble Liquid (SL) technology ensures easy mixing, high tank stability, and superior spreading on waxy weed leaves for maximum absorption. -
🌿
Proven Yield Protection:
Field trials show that timely application of Zumba can deliver yields comparable to manual weeding, but at a fraction of the cost (approx. ₹1200 vs ₹4500+ for labor).

How It Works: Mode of Action
Zumba attacks weeds through two distinct physiological pathways, making it difficult for weeds to survive.
- Stops Grass Growth (Fluazifop-P-butyl): It is absorbed by leaves and moves systemically to the roots and growing points. It inhibits the enzyme Acetyl-CoA Carboxylase (ACCase), stopping the production of lipids needed for cell membranes. The grass rots from the center ("dead heart").
- Burns Broadleaves (Fomesafen): This contact-action component inhibits the Protoporphyrinogen Oxidase (PPO) enzyme. When exposed to sunlight, this causes a buildup of reactive compounds (like singlet oxygen, $^1O_2$) that rupture cell membranes, drying out the weed leaves rapidly.
- Selectivity: Soybean and Groundnut plants can metabolize these chemicals quickly, keeping the crop safe while the weeds perish.
Note: This dual mechanism helps in managing weed resistance when used as part of an integrated program.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Soybean |
Grasses: Echinochloa colona (Jungle Rice), Digitaria sp. (Crabgrass), Eleusine indica (Goosegrass) Broadleaves: Trianthema sp. (Carpet Weed), Digera arvensis, Commelina benghalensis |
| Groundnut |
Grasses: Dactyloctenium aegyptium, Chloris barbata Broadleaves: Amaranthus viridis, Phyllanthus niruri, Cleome viscosa |
| Sedges | Offers suppression of sedges like Cyperus rotundus (Purple Nutsedge), helping the crop canopy close over them. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Never under-dose water volume.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Soybean | 400 ml | 200 Liters | 2 ml | 71 |
| Groundnut | 400 ml | 200 Liters | 2 ml | 82 |
| Knapsack Sprayer (15L) | - | - | 30 ml / Tank | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply when weeds are young and actively growing, ideally at the 2 to 4 leaf stage (approx. 15-20 days after sowing). Spraying late on mature weeds reduces effectiveness.
- Mixing: Fill the spray tank half with water, add the required dose of Zumba, mix well, and then add the remaining water. No extra surfactant (stickers) is usually needed as Zumba is pre-loaded with adjuvants.
- Coverage: Use a Flat Fan or Flood Jet nozzle. Ensure you use 200 Liters of water per acre. Good coverage is vital for the contact action of Fomesafen.
- Safety: Always wear PPE (gloves, mask, goggles). Fomesafen can be a skin irritant. Wash hands thoroughly after use.
Frequently Asked Questions
1. My crop leaves turned bronze/speckled after spraying. Is the crop dying?
No, do not panic. This "bronzing" is a temporary reaction to Fomesafen, especially in hot/humid weather. The new leaves will emerge green and healthy within 7-10 days. Yield is not affected.
2. Can I apply Zumba if it might rain soon?
Yes, Zumba is highly rainfast. It requires only 1 hour of dry weather after application to be effective.
3. Can I mix other chemicals (insecticides) with Zumba?
It is generally recommended to apply herbicides separately to avoid reducing efficacy or increasing crop injury (phytotoxicity).
4. Does Zumba control nutsedge (Motha)?
Zumba suppresses yellow and purple nutsedge effectively (approx. 43% control) if sprayed early, allowing the crop to overtake the weed. It may not completely kill the root system of mature sedges.
5. Will this affect my next crop (Rabi season)?
When used at the recommended dose (400ml/acre), Zumba degrades sufficiently in the soil. Standard rotations like Wheat or Mustard in the Rabi season are generally safe.
Safety & Disclaimer
Always read and follow the instructions on the official product label. The information provided here is for guidance only. Use personal protective equipment (PPE) during application. Avoid spraying near water bodies as Fluazifop-P-butyl is toxic to aquatic life.
