Crystal Sricor Herbicide - Metribuzin 70% WP for Sugarcane, Potato, Tomato, Soybean, Wheat

Crystal Sricor is a selective herbicide from Crystal Crop Protection Limited, formulated with Metribuzin 70% WP (Wettable Powder). It belongs to the Triazinone chemical group and works as a photosynthesis inhibitor to control a wide range of narrow and broad leaf weeds, including Cyperus rotundus (nutgrass), in major crops like Sugarcane, Potato, Tomato, Soybean, and Wheat.

Weeds compete with crops for water, nutrients, sunlight, and space, leading to significant yield losses if not managed early. Crystal Sricor provides effective pre-emergence and early post-emergence control, stopping weeds before they can harm the crop. The wettable powder formulation mixes easily with water and can be applied using standard spray equipment, making it a practical choice for Indian farmers looking for reliable weed management.

Available in 100 gm, 250 gm, and 500 gm packs, Crystal Sricor offers flexibility for different farm sizes and crop requirements. The dosage ranges from 100 to 300 gm per acre, depending on the crop and growth stage, allowing farmers to tailor application for best results.

Key Benefits

• Controls a broad spectrum of narrow and broad leaf weeds, including tough weeds like Cyperus rotundus (nutgrass)
• Works as a photosynthesis inhibitor, stopping weeds from making food and causing them to die off
• Effective as both pre-emergence and early post-emergence treatment, giving flexibility in application timing
• Suitable for multiple important crops — Sugarcane, Potato, Tomato, Soybean, and Wheat — making it a versatile option for farmers growing different crops
• Wettable powder formulation mixes easily with water and applies uniformly through standard spray equipment
• Available in multiple pack sizes (100 gm, 250 gm, 500 gm) to suit small and large farms alike
• Helps reduce weed competition, leading to better crop growth and higher potential yields

How It Works

Crystal Sricor contains Metribuzin, which belongs to the Triazinone chemical group. It works by inhibiting photosynthesis in target weeds. When applied to the soil or to young weeds, Metribuzin is absorbed by the weed roots and leaves. It then moves within the weed and blocks the Photosystem II (PSII) process — a critical step in photosynthesis. Without the ability to convert sunlight into energy, the weed cannot produce food and gradually dies.

Metribuzin has both soil and foliar activity. When applied as a pre-emergence treatment, it forms a herbicide layer in the topsoil. As weed seeds germinate and their roots grow through this treated layer, they absorb the chemical and die before they can establish. When applied as an early post-emergence spray, the herbicide is absorbed by the leaves of young, actively growing weeds, stopping them quickly.

This dual mode of action — soil and foliar uptake — makes Crystal Sricor effective against a wide range of narrow leaf (grassy) and broad leaf weeds, as well as sedges like Cyperus rotundus. The speed of action depends on weed size and growing conditions, but affected weeds typically show yellowing and stunting within a few days of application, followed by complete die-off.

Recommended Dosage & Application

The dosage of Crystal Sricor depends on the crop and the crop stage. Below is the general dosage guidance:

• Dosage per Acre: 100 to 300 gm per acre (depending on crop and crop stage)
• Application Method: Spray application (wettable powder mixed with water)
• Mode of Application: Powder (mixed with water for spray)

Important: Always use the recommended dose for your specific crop. Consult the product label or a local agriculture expert for the exact dosage for your crop and local weed pressure conditions.

When to Use

Crystal Sricor can be used both as a pre-emergence and early post-emergence herbicide. The best time to apply depends on the crop and the weed growth stage:

• Pre-emergence: Apply soon after sowing or planting, before weed seeds germinate. This creates a protective barrier in the soil that stops weeds as they sprout.
• Early Post-emergence: Apply when weeds are young and actively growing (typically 2-4 leaf stage). Weeds are most vulnerable at this stage and easier to control.
• Crop Stage: The exact timing varies by crop. For example, in Potato and Tomato, application is typically done after planting but before crop emergence or at early weed stage. In Sugarcane and Soybean, timing depends on the cropping system and local practices.

Apply when soil moisture is adequate for good herbicide activation. Avoid application when heavy rain is expected within 24 hours, as this may wash away the chemical before it is absorbed.

Step by Step Usage Instructions

1. Read the label: Before using, carefully read the product label for crop-specific dosage and safety instructions.
2. Calculate the dose: Measure the correct quantity of Crystal Sricor based on your crop and field size (100-300 gm per acre as recommended).
3. Prepare the spray solution: Fill the spray tank with half the required amount of clean water. Add the measured quantity of Crystal Sricor WP powder while stirring continuously. Mix well until the powder is fully dissolved. Add the remaining water and stir again.
4. Use recommended water volume: Ensure sufficient water volume (typically 200-500 litres per acre depending on spray equipment) for uniform coverage of the soil or weed foliage.
5. Apply uniformly: Spray evenly across the entire field using a knapsack sprayer or power sprayer with a flat fan nozzle. Ensure good coverage of the soil surface (for pre-emergence) or weed foliage (for post-emergence).
6. Clean equipment: After spraying, thoroughly clean all spray equipment with water. Do not dispose of leftover spray solution or rinse water near water bodies or drainage channels.

Precautions & Safety

• Wear protective clothing, gloves, and a mask while mixing and spraying the product
• Avoid inhalation of the powder during mixing — use in a well-ventilated area
• Avoid contact with skin, eyes, and clothing. In case of contact, wash immediately with plenty of water
• Do not eat, drink, or smoke while handling or applying the product
• Keep the product away from children, pets, and livestock
• Store in a cool, dry place away from direct sunlight and moisture
• Keep away from food, feed, and drinking water containers
• Avoid spray drift to neighbouring crops, especially those sensitive to Metribuzin
• Do not apply near water bodies, ponds, or wells to prevent water contamination
• Wash hands and face thoroughly with soap and water after handling and spraying
