Crystal Awsum Herbicide - Penoxsulam 2.67% W/W OD for Paddy Weed Control

Crystal Awsum is a selective post-emergence herbicide specially developed for transplanted paddy crops. It contains Penoxsulam 2.67% W/W in an Oil Dispersion (OD) formulation, which gives it excellent spreading and sticking properties on weed surfaces. This herbicide is designed to control a broad spectrum of weeds, including both grassy weeds like barnyard grass (Echinochloa) and broadleaf weeds like nutsedge (Cyperus), which are common problems in paddy fields.

Weed competition is one of the biggest reasons for yield loss in paddy farming. Crystal Awsum helps farmers manage this challenge effectively by providing broad-spectrum weed control at the right stage of crop growth. The oil dispersion formulation ensures better coverage and adhesion on weed leaves, making the herbicide more effective even in field conditions. By keeping the field weed-free during the critical growth period, this product helps the paddy crop grow healthier and produce better yields.

Crystal Awsum is manufactured by Crystal Crop Protection, a trusted name in Indian agriculture. It is available in convenient pack sizes of 200 ml, 400 ml, and 1 litre, making it suitable for small and large farms alike. The recommended dose is 400 ml per acre, applied 15 to 20 days after sowing or transplanting. This product is a practical and reliable solution for paddy farmers looking to protect their crop from weed pressure.

Key Benefits

• Broad-spectrum weed control — effectively manages both grassy weeds (Echinochloa) and broadleaf weeds (Cyperus) in one application
• Selective action — targets weeds without harming the transplanted paddy crop when used as directed
• Oil Dispersion formulation — provides better coverage, adhesion, and penetration on weed surfaces compared to conventional formulations
• Post-emergence effectiveness — works on actively growing weeds, giving farmers flexibility to apply after seeing weed emergence
• Promotes healthier crop — by reducing weed competition, the paddy crop gets more nutrients, water, and sunlight for lush green growth
• Convenient application timing — single application at 15–20 days after transplanting fits well into standard paddy farming practices
• Available in multiple pack sizes — 200 ml, 400 ml, and 1 litre options suit different farm sizes and budgets

How It Works

Crystal Awsum contains Penoxsulam, which belongs to the triazolopyrimidine sulfonamide group of herbicides. Penoxsulam works by inhibiting the enzyme acetolactate synthase (ALS), which is essential for the production of certain amino acids in plants. When weeds absorb Penoxsulam through their leaves and roots, this enzyme is blocked, stopping the weed from making the proteins it needs to grow and survive.

Because Penoxsulam is a systemic herbicide, it moves within the weed plant after absorption, reaching growing points and roots. This ensures that the entire weed plant is affected, not just the parts that were sprayed. The Oil Dispersion (OD) formulation helps the herbicide stick better to weed leaves and resist wash-off from light rain or irrigation, improving overall effectiveness.

Weeds stop growing soon after application, and visible symptoms like yellowing and wilting appear within a few days. Complete weed death usually occurs within 1 to 2 weeks, depending on weed size and growing conditions. The selective nature of Penoxsulam means it targets problem weeds in paddy while being safe for the transplanted rice crop when applied at the recommended dose and timing.

Application Method: Mix the required quantity of Crystal Awsum in sufficient water (usually 150–200 litres per acre) and spray uniformly on the weed-infested field. Ensure proper agitation of the spray solution to keep the product well-mixed. Apply as a foliar spray directly onto actively growing weeds.

When to Use

Crystal Awsum should be applied 15 to 20 days after sowing or transplanting paddy. This is the stage when most problematic weeds like Echinochloa (barnyard grass) and Cyperus (nutsedge) have emerged and are actively growing, but before they become too large and compete heavily with the crop. Applying at this early post-emergence stage gives the best control results.

The field should have sufficient moisture at the time of application for the herbicide to work effectively. Avoid application when heavy rain is expected within a few hours, as this may reduce the product's effectiveness. Apply when weeds are small and actively growing for the best results. Do not apply to crops under stress from drought, waterlogging, or pest damage.

Step by Step Usage Instructions

1. Check the field: Walk through the paddy field 15–20 days after transplanting. Look for emerged weeds like barnyard grass and nutsedge.
2. Measure the dose: Take 400 ml of Crystal Awsum for each acre of paddy field.
3. Prepare the spray solution: Fill the spray tank with half the required water (about 75–100 litres per acre). Add the measured quantity of Crystal Awsum and mix well. Add the remaining water and stir again to ensure uniform mixing.
4. Ensure proper agitation: Keep the spray solution agitated while spraying to prevent settling of the formulation.
5. Spray uniformly: Apply the mixture as a uniform foliar spray over the entire field, ensuring good coverage of weed leaves. Use a knapsack sprayer or power sprayer with a flat fan nozzle for even application.
6. Maintain field moisture: Ensure the field has adequate moisture (but not flooded) at the time of application for best results.
7. Clean equipment: After spraying, thoroughly clean all spray equipment with water to remove any residue.
