Crystal Amora Herbicide - Quizalofop Ethyl 3% + Fomesafen 12% SC for Soybean & Groundnut

Crystal Amora is a selective post-emergence herbicide from Crystal Crop Protection, specially formulated to control both grassy weeds and broadleaf weeds in soybean and groundnut crops. It contains two powerful active ingredients — Quizalofop Ethyl 3% and Fomesafen 12% — in a Suspension Concentrate (SC) formulation. This dual-action herbicide works through two different modes of action: Quizalofop Ethyl acts as an ACCase inhibitor that disrupts lipid synthesis in grassy weeds, while Fomesafen inhibits the PPO enzyme causing rapid cell membrane damage in broadleaf weeds. Together, they provide broad-spectrum weed control in a single spray.

Crystal Amora is a post-emergent herbicide, meaning it is applied after the crop has emerged and weeds are actively growing. It combines systemic action (for grass control) and contact action (for broadleaf control), ensuring thorough weed elimination. The product is quickly absorbed by weeds, with visible effects appearing within 3–5 days of application. It is rainfast within 2 hours, making it reliable even in unpredictable weather. Crystal Amora is safe for the main crop and does not cause any harm or shock when used as per recommended dosage. It also offers residual protection that helps prevent weed regrowth, leading to cleaner fields and better crop yields.

Key Benefits

• Broad-spectrum weed control — Eliminates both grassy weeds and broadleaf weeds in one application, saving time and labour.
• Fast visible results — Weeds start showing symptoms within 3–5 days of spraying, with complete control in 10–15 days.
• Dual mode of action — Combines systemic (ACCase inhibition) and contact (PPO inhibition) action for thorough weed kill.
• Rainfast in 2 hours — Resistant to wash-off after 2 hours of application, reducing risk from unexpected rain.
• Selective and crop-safe — Targets weeds without harming soybean and groundnut crops when used at recommended dosage.
• Long-lasting residual effect — Provides extended protection against weed regrowth, keeping fields cleaner for longer.
• Higher crop yield — By reducing weed competition, the crop gets more nutrients, water, and sunlight, leading to better productivity.

How It Works

Crystal Amora works through two complementary modes of action to control different types of weeds effectively.

Quizalofop Ethyl (3%) is a systemic herbicide that is absorbed by the leaves and stems of grassy weeds. It moves through the plant and inhibits the ACCase enzyme, which is essential for lipid (fat) synthesis in grass plants. Without lipids, the cell membranes of the weed break down, and the weed stops growing. Within a few days, the grassy weeds turn yellow, then brown, and eventually die. This action is selective — it only affects grassy weeds and does not harm broadleaf crops like soybean and groundnut.

Fomesafen (12%) works as a contact herbicide against broadleaf weeds. It is absorbed by the foliage and inhibits the protoporphyrinogen oxidase (PPO) enzyme. This disruption causes rapid cell membrane damage, leading to weed desiccation (drying up) and death. The effects are visible quickly, often within 3–5 days. Fomesafen also has some residual activity in the soil, providing continued protection against germinating broadleaf weeds.

Together, these two active ingredients provide a powerful combination: Quizalofop Ethyl moves systemically through grassy weeds to kill them from within, while Fomesafen acts on contact to rapidly desiccate broadleaf weeds. This dual approach ensures comprehensive weed management in a single spray application.

Recommended Dosage & Application

Crop	Target Weeds	Dosage (per acre)	Water Volume	Time of Application
Soybean	Grassy & Broadleaf Weeds	600 ml	200–250 litres per hectare (approx. 80–100 litres per acre)	2–4 weed leaf stage (post-emergence)
Groundnut	Grassy & Broadleaf Weeds	600 ml	200–250 litres per hectare (approx. 80–100 litres per acre)	2–4 weed leaf stage (post-emergence)

Method of Application: Foliar spray using a knapsack sprayer fitted with a flat-fan nozzle. Apply uniformly over the target weeds. Ensure thorough coverage for best results.

Note: Some sources also mention a dosage range of 800–1000 ml per hectare (which equals approximately 320–400 ml per acre). Always follow the specific dosage mentioned on the product label for your region and crop.

When to Use

Crystal Amora should be applied as a post-emergence treatment when weeds are in their early growth stages — specifically at the 2–4 leaf stage. At this stage, weeds are young, actively growing, and most susceptible to herbicide action. Applying early ensures maximum absorption and effectiveness of both active ingredients.

The ideal time to spray is when the crop is well-established but weeds have just emerged and are small. Avoid spraying when weeds are mature or have already flowered, as control may be reduced. Apply during calm weather conditions — avoid spraying during high winds or when rain is expected within 2 hours of application. The product is rainfast after 2 hours, so light rain after this period will not reduce effectiveness.

For best results, spray when the weather is dry and sunny, as this helps the herbicide dry on weed foliage and improves absorption. Early morning or late afternoon spraying is recommended to avoid heat stress and ensure good coverage.

Step by Step Usage Instructions

1. Prepare the spray solution: Fill the spray tank with half the required amount of clean water. Add the measured quantity of Crystal Amora (600 ml per acre) and mix well. Add the remaining water and stir thoroughly to ensure uniform mixing.
2. Check the weather: Ensure no rain is expected for at least 2 hours after spraying. Avoid spraying during strong winds or extreme heat.
3. Wear protective gear: Put on gloves, goggles, and a mask before handling the herbicide and during spraying.
4. Spray uniformly: Use a knapsack sprayer with a flat-fan nozzle. Apply the solution evenly over the target weeds, ensuring complete coverage of weed foliage. Avoid spraying directly on the crop canopy more than necessary.
5. Clean equipment: After spraying, wash the sprayer thoroughly with clean water to remove any herbicide residue. Do not dispose of wash water near water bodies or drinking water sources.
6. Post-application care: Do not enter the sprayed field until the spray solution has dried completely. Wash hands, face, and any exposed skin with soap and water after handling.

Compatibility

Crystal Amora is compatible with most commonly used herbicides and fertilizers. However, before mixing with any other product, conduct a small jar test to check for physical compatibility — mix small quantities of both products in a jar and observe for any settling, clumping, or separation. Do not mix with highly alkaline substances. Always follow the mixing order: wettable powders first, then SC formulations, then liquids, and adjuvants last.

Precautions & Safety

• Personal protection: Wear gloves, goggles, and a mask while handling and spraying the herbicide.
• Avoid drift: Do not spray during high winds. Prevent spray drift to nearby sensitive crops, water bodies, or non-target areas.
• Weather conditions: Do not spray during rain or when rain is expected within 2 hours. Avoid spraying in extreme heat or direct sunlight.
• Storage: Store the product in a cool, dry place away from food, feed, and drinking water. Keep out of reach of children and animals.
• Hygiene: Wash hands and face thoroughly with soap and water after handling. Do not eat, drink, or smoke while spraying.
• Equipment cleaning: Wash spray equipment thoroughly after use to avoid contamination of other crops or chemicals.

PHI / REI & Storage

• Pre-Harvest Interval (PHI): Maintain a minimum of 60 days between the last application and harvest for soybean. Follow label instructions for groundnut.
• Storage: Store in a cool, dry, and shaded area away from direct sunlight and moisture. Keep the container tightly sealed when not in use.
• Shelf Life: Use within the expiry period mentioned on the product label.
