IIL Hachiman Herbicide - Quizalofop 7.5% + Imazethapyr 15% EC for Soybean, Groundnut & Pulses

Product Overview

IIL Hachiman is a broad-spectrum, post-emergence herbicide from Insecticides India Limited (IIL) that combines two powerful active ingredients — Quizalofop Ethyl 7.5% and Imazethapyr 15% in an Emulsifiable Concentrate (EC) formulation. This dual-action herbicide is designed to control both grassy weeds and broadleaf weeds in one single spray, making weed management simpler and more effective for farmers.

IIL Hachiman is recommended for use in Soybean, Groundnut, Pulses (Chickpea, Lentil, Green Gram, Black Gram), and Oilseeds (Mustard, Sunflower). It works by being absorbed through the leaves and roots of weeds, moving systemically within the plant to stop growth at the source. The product provides long-lasting control, reduces weed competition for nutrients and water, and helps improve crop yield. With a rainfast period of just 2–3 hours, it offers reliable performance even in variable weather conditions.

This herbicide is a practical choice for farmers looking for a selective, crop-safe solution that tackles multiple weed types without damaging the main crop. Available in pack sizes of 175 ml, 500 ml, and 1 litre, it suits both small and large farms.

Key Benefits

• Dual weed control in one spray: Controls both grassy weeds and broadleaf weeds simultaneously, saving time and labour.
• Systemic action for complete kill: Absorbed through leaves and roots, the herbicide moves inside the weed to stop growth from within.
• Long-lasting residual effect: Provides extended weed protection and reduces the need for repeated applications.
• Crop-safe and selective: Highly selective to recommended crops like soybean, groundnut, and pulses — no crop damage when used as directed.
• Rainfast in 2–3 hours: Quick rainfastness means less worry about unexpected rain after spraying.
• Reduces weed resistance: Dual mode of action (ACCase inhibitor + ALS inhibitor) helps delay the development of weed resistance.
• Improves crop yield: By eliminating weed competition, crops get more nutrients, water, and sunlight for better growth and higher yields.

How It Works

IIL Hachiman contains two active ingredients that work through different mechanisms to control a wide range of weeds. Quizalofop Ethyl (7.5%) is a selective post-emergence herbicide that belongs to the ACCase inhibitor group. It targets grassy weeds by blocking the enzyme responsible for fatty acid synthesis (lipid biosynthesis). Without fatty acids, the weed's cell membranes cannot form properly, leading to growth inhibition and eventual death of the weed.

Imazethapyr (15%) belongs to the ALS inhibitor group. It works by blocking the acetolactate synthase (ALS) enzyme, which is essential for the production of certain amino acids (valine, leucine, and isoleucine) in broadleaf weeds. Without these amino acids, protein synthesis stops, and the weed cells cannot divide or grow, leading to plant death.

Both ingredients are systemic in nature — they are absorbed through the leaves and roots of weeds and move through the plant's vascular system (xylem and phloem). They accumulate in the meristematic regions (growing points) where they disrupt growth processes. This dual-action systemic approach ensures that weeds are controlled from the inside out, providing thorough and lasting results.

Application Method: Use a knapsack sprayer fitted with a flat-fan nozzle for uniform coverage. Apply as a foliar spray when weeds are in the early growth stage (2–4 leaf stage). Ensure good soil moisture at the time of application for best results.

When to Use

IIL Hachiman is a post-emergence herbicide and should be applied 15–20 days after sowing the crop. This is the ideal time when weeds are in their early growth stage (2–4 leaf stage) and are most vulnerable to the herbicide. The product is effective during both Kharif and Rabi seasons, making it a versatile option for year-round weed management.

For best results, apply when weeds are actively growing and there is adequate soil moisture. Avoid spraying on wet crops or when rain is expected within 2–3 hours, although the formulation becomes rainfast within that window. Early application ensures that weeds are controlled before they can compete heavily with the crop for nutrients, water, and sunlight.

Step by Step Usage Instructions

1. Check the stage: Ensure the crop is 15–20 days old and weeds are in the 2–4 leaf stage (early growth).
2. Prepare the spray solution: Fill the spray tank with half the required water. Add the measured quantity of IIL Hachiman (175–200 ml per acre) and mix well. Add the remaining water and stir again to ensure a uniform solution.
3. Use proper equipment: Use a knapsack sprayer with a flat-fan nozzle for even and uniform coverage over the crop and weeds.
4. Spray evenly: Apply the solution as a foliar spray, ensuring all weed foliage is thoroughly covered. Do not over-spray or allow runoff.
5. Check soil moisture: For best results, ensure the field has adequate moisture at the time of spraying.
6. Post-application care: Do not disturb the field for at least 2–3 hours after spraying. The product becomes rainfast within this period.
7. Clean equipment: After spraying, thoroughly clean all spray equipment with water. Do not dispose of leftover solution or rinse water near water bodies.

Compatibility

IIL Hachiman can be tank-mixed with most commonly used insecticides and fungicides after performing a jar test to check compatibility. Avoid mixing with strong alkaline or acidic chemicals. Always mix only the quantity needed for one spray and use the solution immediately. When in doubt about compatibility with a specific product, consult the product label or your local agri-dealer.

Precautions & Safety

• Personal Protective Equipment (PPE): Wear gloves, goggles, and a mask while handling and spraying the herbicide.
• During spraying: Avoid inhalation of spray mist. Do not eat, drink, or smoke while handling or spraying.
• After spraying: Wash hands and exposed skin thoroughly with soap and water.
• Storage: Store in original containers in a cool, dry, and ventilated place away from direct sunlight. Keep out of reach of children and animals.
• Environmental safety: Do not spray near water bodies, ponds, or wells to prevent contamination. Avoid drift onto non-target crops or sensitive areas.
• Disposal: Dispose of empty containers safely as per local regulations. Do not reuse containers for any other purpose.
• Emergency: In case of skin contact, wash immediately with soap and water. If swallowed, seek medical attention immediately and show the product label to the doctor.

Side Effects & Phytotoxicity

When used as per recommended dosage and application guidelines, IIL Hachiman is selective and safe for the recommended crops (Soybean, Groundnut, Pulses, Oilseeds). However, spraying on wet crops, during extreme weather, or at higher-than-recommended doses may cause temporary stress or leaf burn. Always follow the recommended dosage and timing to avoid any risk of phytotoxicity.
