Crystal Falon Herbicide - Chlorimuron Ethyl 25% WP for Soybean & Paddy, 15g Pack

Crystal Falon is a selective herbicide from Crystal Phosphates, formulated as Chlorimuron Ethyl 25% WP (Wettable Powder). It belongs to the Sulfonylurea chemical group and works by inhibiting the ALS enzyme in target weeds, effectively stopping their growth. This herbicide is specifically designed to control broad leaf weeds in two major crops — Soybean and Paddy (Rice).

Available in a 15-gram pack, Crystal Falon offers a practical solution for farmers dealing with stubborn broad leaf weed infestations. With a recommended dosage of 9.6 to 15 grams per acre, it provides effective weed control when applied at the right crop stage. The product is manufactured in India by Crystal, a trusted name in the agrochemical industry, and has a shelf life of 2 years when stored properly.

For soybean and paddy farmers, weed competition is a major challenge that reduces yield and increases labour costs. Crystal Falon helps tackle this problem by targeting broad leaf weeds at the root — interfering with essential enzyme activity that weeds need to grow. This makes it a reliable choice for integrated weed management programs in both kharif and rabi seasons.

Key Benefits

• Effectively controls a wide range of broad leaf weeds in Soybean and Paddy crops
• Belongs to Sulfonylurea group with ALS enzyme inhibition mode of action for targeted weed control
• Low dosage requirement — only 9.6 to 15 grams per acre, making it economical for farmers
• Wettable Powder (WP) formulation mixes easily with water for convenient spray application
• Helps reduce manual weeding labour and associated costs in large fields
• Manufactured in India by Crystal, a reliable agrochemical brand with consistent quality
• Shelf life of 2 years allows for safe storage across seasons when kept in proper conditions

How It Works

Crystal Falon contains Chlorimuron Ethyl 25% WP, an active ingredient from the Sulfonylurea chemical group. Once applied to the crop field, the herbicide is absorbed by the leaves and roots of target broad leaf weeds. It moves systemically within the weed plant and reaches the growing points.

The active ingredient works by inhibiting the ALS (Acetolactate Synthase) enzyme, which is essential for the production of branched-chain amino acids (valine, leucine, and isoleucine) in weeds. Without these amino acids, the weed plants cannot produce proteins needed for growth and development. Within a few days of application, weed growth stops completely, and the weeds gradually yellow, wilt, and die off.

Because the mode of action is enzyme-specific, Crystal Falon targets only susceptible broad leaf weeds while being safe for the main crop (Soybean and Paddy) when used at the recommended dosage. This selective action makes it a valuable tool for farmers looking to protect their crop from weed competition without damaging the crop itself.

Application Method: Mix the required quantity of Crystal Falon in sufficient water and spray uniformly over the crop field. Ensure thorough coverage of the weed foliage for best results. Use clean water for mixing.

When to Use

Crystal Falon should be applied when broad leaf weeds are in their early growth stage — typically 2 to 4 leaf stage — for maximum effectiveness. Weeds are most vulnerable at this stage, and the herbicide can stop their growth before they compete heavily with the main crop for nutrients, water, and sunlight.

In Soybean, apply the herbicide after crop emergence but before weeds become well-established. In Paddy (transplanted rice), apply within the recommended window after transplanting when weeds start emerging. Avoid application during extreme heat, heavy rainfall, or when the crop is under moisture stress, as these conditions may reduce herbicide effectiveness.

Timely application is key — delaying beyond the early weed stage may result in reduced control, as older, larger weeds are harder to manage with post-emergence herbicides.

Step by Step Usage Instructions

1. Check the field: Walk through the field and confirm that broad leaf weeds have emerged and are at early growth stage.
2. Calculate the dose: Measure 9.6 to 15 grams of Crystal Falon per acre based on weed pressure and crop stage.
3. Prepare the spray solution: Take a small amount of clean water in a bucket. Add the measured Crystal Falon powder and stir well to make a slurry. Add remaining water and mix thoroughly.
4. Fill the sprayer: Pour the mixed solution into a clean, well-functioning sprayer. Ensure the sprayer nozzle is clean and not clogged.
5. Spray uniformly: Apply the solution evenly across the field, ensuring good coverage of weed foliage. Avoid over-spraying or missing patches.
6. Clean equipment: After spraying, thoroughly rinse the sprayer and all mixing equipment with clean water. Do not dispose of rinse water near water bodies.
7. Observe the field: Monitor the field over the next 7-10 days. Weed growth should stop, and weeds will gradually yellow and die.
