Kimio Herbicide (Quizalofop-p-ethyl 10% EC) by Nichino India
The Ultimate Japanese Solution for Grassy Weeds in Soybean & Cotton
Kimio is a specialized, systemic post-emergence herbicide designed to protect broadleaf crops from aggressive grassy weeds. Manufactured by Nichino India using advanced Japanese technology (Nihon Nohyaku Co., Ltd.), it targets weeds at the root to ensure they don't grow back.
Best For: Farmers facing labor shortages who need a cost-effective, high-purity solution for controlling Barnyard grass, Viper grass, and Bermuda grass in Soybean, Cotton, Groundnut, and Onion fields.
Why Choose This Product? Key Benefits
-
⏱️
Rapid Rainfastness (1 Hour): Formulated to absorb quickly. It remains effective even if it rains just 60 minutes after spraying—perfect for the Indian monsoon season.
-
🛡️
Complete Crop Safety: Highly selective formulation. It attacks the specific enzymes in grasses but leaves your broadleaf crops (Soybean, Cotton, Pulses) completely unharmed.
-
⏳
Systemic Action (Kills Roots): Translocates from the leaves down to the roots and rhizomes, ensuring difficult perennial weeds like Cynodon (Doob grass) are permanently eliminated.
-
🌧️
Superior Formulation: The 10% EC formulation uses high-grade Japanese solvents that ensure stable emulsions and consistent results, even in fluctuating temperatures.
-
🌿
High Purity Active Ingredient: Contains the high-purity 'P' isomer of Quizalofop. This ensures maximum biological activity per gram, offering better control with less chemical load.

How It Works: Mode of Action
Kimio works by targeting the plant's ability to produce lipids (fats), which are essential for cell growth.
[Image of Quizalofop-p-ethyl mode of action diagram]- Absorption: The herbicide is absorbed by the weed leaves within 1 to 4 hours of spraying.
- Translocation: It moves through the phloem (nutrient system) to the growing points, including the roots.
- Termination: It inhibits the ACCase enzyme, stopping lipid synthesis. The weed stops growing in 2 days, turns yellow in 5-7 days, and dies completely in 14-21 days.
Note: Because broadleaf crops have a different type of ACCase enzyme, they are naturally immune to Kimio.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Soybean | Barnyard grass (Echinochloa), Viper grass (Dinebra), Crabgrass (Digitaria) |
| Cotton | Barnyard grass, Goosegrass (Eleusine), Viper grass |
| Groundnut, Black Gram, Onion | Crowfoot grass (Dactyloctenium), Crabgrass, Goosegrass |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Using less water than recommended (e.g., only 2-3 pumps) significantly reduces efficacy.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Soybean | 300 - 400 ml | 150 - 200 L | 2 - 2.5 ml | 80 - 90 Days |
| Cotton | 400 ml | 150 - 200 L | 2.5 ml | - |
| Onion, Groundnut, Black Gram | 300 - 400 ml | 150 - 200 L | 2 - 2.5 ml | 7 - 15 Days (Onion) |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. *Note: Use 400ml/acre for dense infestations or perennial weeds.
How to Apply: Best Practices
- Timing: Apply when weeds are in the 2-4 leaf stage (active growth). Spraying too late (when weeds are flowering) reduces results.
- Mixing: Do NOT mix with broadleaf herbicides (like 2,4-D) as they can stop Kimio from working. Apply them 3-5 days apart.
- Coverage: Use a Flat Fan or Flood Jet nozzle. Ensure soil has sufficient moisture; avoid spraying on drought-stressed weeds.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid use near fish ponds.
Frequently Asked Questions
1. Does Kimio affect my soybean or cotton crop?
No. Kimio is highly selective. It only affects the enzymatic pathway found in grasses. Broadleaf crops like soybean, cotton, and groundnut are naturally immune to it.
2. What if it rains after spraying?
Kimio is rainfast within 1 hour. If it rains 60 minutes after you finish spraying, the product has already been absorbed and will remain effective.
3. Can I use Kimio in Paddy (Rice) fields?
Absolutely not. Rice is a grass crop. Kimio will kill rice just as it kills weeds. Use it only in broadleaf crops.
4. Can I mix it with insecticides?
Yes, Kimio is generally compatible with insecticides like Indoxacarb or Emamectin Benzoate for controlling caterpillars simultaneously.
5. How long does it take to see results?
Weeds stop growing within 2 days. Yellowing starts in 5-7 days, and complete death ("dead heart") occurs within 14-21 days.
