Crystal Hola Herbicide - Halosulfuron Methyl 12% + Metribuzin 55% WG for Sugarcane Weed Control

Crystal Hola is a powerful broad-spectrum herbicide specifically designed for weed management in sugarcane crops. It contains a unique combination of two active ingredients: Halosulfuron Methyl 12% and Metribuzin 55% in a water-dispersible granule (WG) formulation. This dual-action herbicide provides both stomach and contact action to effectively control a wide range of weeds, including tough-to-manage sedges and grasses.

The product is particularly effective against Cyperus rotundus (nutgrass/nutsedge), a problematic weed in sugarcane that competes heavily for nutrients and reduces crop yield. Crystal Hola also controls other common weeds like Eleusine indica (goosegrass) and Dactyloctenium aegyptium (crowfoot grass). By keeping the field weed-free during the critical early growth stages, this herbicide helps sugarcane produce higher tillers and better yields. It is safe to the crop when used as per recommended dosage and timing.

Crystal Hola is available in convenient pack sizes of 200 gm, 400 gm, and 1 kg, making it suitable for both small and large sugarcane farmers. The WG formulation dissolves easily in water and is simple to apply with standard spraying equipment.

Key Benefits

• Broad-spectrum weed control – Effectively controls both broadleaf weeds and grasses, reducing the need for multiple herbicides
• Effective against nutgrass (Cyperus rotundus) – Controls this stubborn weed by acting on the nuts/tubers, preventing regrowth
• Dual mode of action – Combines stomach and contact action for more complete and reliable weed kill
• Safe to sugarcane crop – Does not harm the main crop when applied at the recommended dose and stage
• Promotes higher tillering – By reducing weed competition, the sugarcane crop produces more tillers for better yield
• Easy-to-use WG formulation – Water-dispersible granules mix easily and stay in suspension for uniform application
• Multiple pack size options – Available in 200 gm, 400 gm, and 1 kg packs to suit different farm sizes

How It Works

Crystal Hola works through a combination of two active ingredients that attack weeds in different ways. Halosulfuron Methyl is a systemic herbicide that is absorbed by the leaves and roots of weeds. It moves through the plant and stops cell division by inhibiting the ALS (acetolactate synthase) enzyme, which is essential for weed growth. This action slowly stops the weed from growing and eventually kills it.

Metribuzin works mainly through contact and some systemic action. It is absorbed by the roots and leaves and interferes with photosynthesis in the weed plants. By blocking the electron transport chain in photosystem II, it stops the weed from producing food, causing it to yellow, wilt, and die.

Together, these two active ingredients provide both immediate contact kill and longer-lasting systemic control. The combination is especially effective against Cyperus rotundus because Halosulfuron Methyl can move down to the nuts (tubers) and stop them from sprouting again, while Metribuzin provides quick knockdown of emerged weeds. This dual action ensures that both existing weeds and their underground reproductive structures are controlled, giving sugarcane a clean start for healthy growth.

Technical Specifications

Recommended Dosage & Application

Application Method: Mix the required quantity of Crystal Hola in sufficient water and spray uniformly on the weed-infested field using a knapsack sprayer or power sprayer. Ensure proper mixing for uniform suspension.

When to Use

Crystal Hola should be applied at the 3-5 leaf stage of the weeds. This is the ideal time because young weeds are most vulnerable to herbicide action and have not yet developed strong root systems or underground reproductive structures. Applying at this stage ensures maximum control with the recommended dose.

For sugarcane, the application is typically done after planting but before the crop canopy covers the ground, allowing the spray to reach the weeds effectively. The field should be free of clods and debris for uniform coverage. Avoid application when rain is expected within 4-6 hours, as this may wash off the product and reduce effectiveness.

Step by Step Usage Instructions

• Step 1: Fill the spray tank with half the required amount of clean water
• Step 2: Add the measured quantity of Crystal Hola (400 gm per acre) to the tank
• Step 3: Stir or agitate thoroughly until the granules dissolve completely
• Step 4: Add the remaining water and mix well to ensure uniform suspension
• Step 5: Spray evenly on the target weeds, ensuring good coverage of weed foliage
• Step 6: Clean the spray equipment thoroughly after use with clean water

Precautions & Safety

• Wear protective clothing, gloves, and mask while handling and spraying the herbicide
• Avoid inhalation of dust or spray mist during mixing and application
• Do not eat, drink, or smoke while handling the product
• Keep the product away from children, pets, and livestock
• Store in a cool, dry place away from direct sunlight and moisture
• Do not contaminate ponds, rivers, or water sources with the product or its container
• Wash hands and exposed skin thoroughly with soap and water after use
• Dispose of empty containers safely – do not reuse for any purpose

Side Effects & Phytotoxicity

Crystal Hola is safe to the sugarcane crop when used at the recommended dose of 400 gm per acre and applied at the correct weed stage. Overdosing or application under unfavorable conditions (extreme heat, waterlogged soil) may cause temporary crop stress. Always follow the recommended dosage and application timing to avoid any risk to the crop.

Storage

• Store in original tightly closed container in a cool, dry place
• Keep away from food, feed, and drinking water
• Protect from moisture and high temperatures
• Check the manufacturing and expiry date on the pack before purchase
