Dhanuka Craze is a selective pre-emergence herbicide containing Pretilachlor 50% EC. It is registered for early weed control in transplanted rice and is applied before weed emergence, within 0–3 days after transplanting.
Registered use: Transplanted rice only, against specified annual grasses, sedges and broadleaf weeds. Follow the current physical product label for the exact field rate, water volume, application method and safety precautions.
Important: Craze is not a post-emergence rescue herbicide. Do not assume use in direct-seeded rice or any crop not listed on the current label.
Item description
Dhanuka Craze Pretilachlor 50% EC Herbicide
Craze by Dhanuka is a selective pre-emergence herbicide containing Pretilachlor 50% EC for weed control in transplanted rice.
It is used before weeds emerge, within 0–3 days after rice transplantation. The registered spectrum includes specified annual grasses, sedges and broadleaf weeds that compete with young rice plants during crop establishment. Correct timing is essential: Craze is designed to act on germinating weeds and is not a post-emergence rescue treatment for weeds that are already established.
Key Benefits for Transplanted Rice
- Early-season weed management: Intended for application before weed emergence during the first 0–3 days after transplanting.
- Registered multi-weed spectrum: Covers specified grasses, sedges and broadleaf weeds listed on the Indian major-use table.
- Selective rice use: Designed for transplanted rice when the physical label rate, timing and field directions are followed.
- Group 15 mode of action: Pretilachlor inhibits very-long-chain fatty acid synthesis in susceptible germinating weeds.
- EC formulation: An emulsifiable concentrate intended to be measured and applied exactly according to the current product label.

How Craze Works
Pretilachlor belongs to HRAC/WSSA Group 15. It is absorbed mainly by the emerging shoot tissues of germinating weeds and interferes with the synthesis of very-long-chain fatty acids needed for early growth. Susceptible weeds are controlled as they germinate and attempt to emerge. Because the herbicide targets this early stage, delayed application after weeds have emerged may not provide the intended result.
Registered Weeds in Transplanted Rice
| Weed Group | Registered Species |
|---|---|
| Grasses | Echinochloa crusgalli, Echinochloa colonum, Leptochloa chinensis, Panicum repens |
| Sedges | Cyperus difformis, Cyperus iria, Fimbristylis miliacea |
| Broadleaf Weeds | Eclipta alba, Ludwigia parviflora, Monochoria vaginalis |
Registered Dose, Water Volume and PHI
| Crop | Timing | Product Rate | Water Volume | PHI |
|---|---|---|---|---|
| Transplanted Rice | Pre-emergence; within 0–3 days after transplanting | 1.0–1.5 L/ha; 400–600 ml/acre | 500–700 L/ha; 200–280 L/acre | 75–90 days |
PHI means pre-harvest interval. The current physical pack label is the final authority for the selected pack, field and application equipment.
Application Guidance
- Crop system: Use only in transplanted rice where the current physical label permits use.
- Timing: Apply before weed emergence, within 0–3 days after transplanting. Do not treat this as a post-emergence rescue herbicide.
- Measurement: Measure the label rate accurately and apply uniformly with label-directed equipment.
- Mixing: Do not add another herbicide, insecticide, fungicide, fertilizer or adjuvant unless the current Craze label specifically permits that mixture.
- Drift and water protection: Prevent drift, runoff and contamination of irrigation channels, ponds and other water bodies.
Frequently Asked Questions
1. Which crop is Craze registered for?
The verified Indian major-use row is for transplanted rice. Do not assume the same use in direct-seeded or nursery rice.
2. When should Craze be applied?
Dhanuka specifies pre-emergence application within 0–3 days after transplanting, before the target weeds emerge.
3. Will Craze control weeds that are already visible?
It is not positioned as a post-emergence rescue herbicide. Select a label-approved option based on the crop, weed species and weed stage.
4. What is the registered rate?
The Indian table lists 1.0–1.5 L/ha in 500–700 L water/ha, with a 75–90 day PHI. Dhanuka states 400–600 ml/acre in 200–280 L water/acre.
5. Can Craze be tank-mixed with another product?
Do not rely on generic compatibility claims. Use a mixture only when the current physical Craze label explicitly permits it and follow qualified local agronomic guidance.
Safety and Label Compliance
Read the current physical label and leaflet before use. Wear the label-specified personal protective equipment, avoid skin and eye contact, do not eat, drink or smoke while handling the product, and wash thoroughly after application.
