Orbit Herbicide (Oxyfluorfen 23.5% EC): Complete Guide for Farmers
Stop spending thousands on manual weeding. Protect your Onions, Tea, and Groundnuts with Orbit.
Manual weeding is becoming too expensive and labor is hard to find. Orbit (Oxyfluorfen 23.5% EC) by Insecticides (India) Ltd is the modern solution. It is a powerful contact herbicide that creates a chemical barrier on the soil surface, stopping weeds before they grow.
Best for: Controlling broadleaf weeds in Onion, Tea, Potato, Groundnut, and Rice without damaging the crop.
Why Choose This Product? Key Benefits
- ⏱️Fast Visible Results: Acts quickly upon contact. You will see weeds drying out and dying within hours of application on a sunny day.
- ?️Double Action Protection: It burns existing young weeds (contact action) and prevents new weed seeds from germinating (residual soil action).
- ⏳Massive Cost Savings: Manual weeding can cost ₹12,000 per acre. Orbit costs approximately ₹500 - ₹1,500 per acre, saving you significant money.
- ?️Strong Soil Binding: It sticks to the soil surface and does not easily leach down to damage crop roots, making it safe for bulb crops like Onion.
- ?Excellent Crop Safety: When used at the right dose and time, it is highly safe for high-value crops like Onion, Tea, and Potato.

How It Works: Mode of Action
Orbit works differently than other weed killers. It requires Sunlight to kill the weeds.
- Contact & Absorption: When sprayed, Orbit lands on the soil or weed leaves and is absorbed into the cells.
- Enzyme Blockage: It blocks a specific enzyme (PPO), causing a buildup of compounds inside the weed cell.
- Sunlight Activation: When sunlight hits the plant, these built-up compounds react explosively, destroying the cell membranes. The weed dries up and dies quickly.
Note: Because it is a contact herbicide, it does not move inside the plant. Good coverage is essential.

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 (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Onion (Pre-Emergence) | 80 - 100 ml | 200 L | 0.5 ml | - |
| Onion (Post-Emergence) | 150 - 200 ml | 200 L | 0.75 - 1 ml | - |
| Tea | 260 - 400 ml | 200 - 300 L | 1.5 - 2 ml | 15 |
| Potato / Groundnut | 170 - 340 ml | 200 L | 0.8 - 1.5 ml | - |
| Rice (Pre-Emergence) | 260 - 400 ml | 200 L | 1.5 - 2 ml | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing (Pre-Emergence): Apply within 0-3 days of sowing/transplanting. The soil must be moist for the chemical barrier to form effectively.
- Mixing: For total control in Onions, you can tank-mix Orbit with Fenoxaprop-p-ethyl (a grass killer) to handle both broadleaf and grassy weeds in one go.
- Coverage: Use a Flat Fan or Flood Jet nozzle. Do NOT use a cone nozzle. Uniform coverage of the soil surface is critical.
- Safety: Always wear PPE (gloves, mask, goggles). This product can cause severe eye irritation, so protect your eyes during mixing. Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Orbit kill grass weeds?
It is weak on established grasses. For complete control, mix it with a graminicide (grass killer) like Fenoxaprop or Quizalofop.
2. Why is sunlight important?
Orbit needs light to activate its weed-killing power. For best results, spray on a bright, sunny day. Cloudy weather may slow down the results.
3. Can I use it on dry soil?
No. For pre-emergence use, soil moisture is mandatory. If the soil is dry, irrigate the field lightly before spraying.
4. Will it damage my Onion crop?
It is safe if used at recommended doses. Avoid spraying during the "flag leaf" stage (when the onion is just emerging from the soil) to prevent scorching.
5. What happens if it rains after spraying?
Since Orbit is a contact herbicide with rapid action, it is generally rainfast after 3-4 hours. However, heavy rain immediately after application may reduce efficacy.
