Imazethapyr 10% SL

Imazethapyr 10% SL

Imazethapyr 10% SL is a selective, systemic herbicide from the imidazolinone chemical group, trusted by soybean, groundnut, and pulse farmers across India for reliable broad-spectrum weed control from a single, well-timed early post-emergence application. Proven by ICAR research to increase legume crop yields by up to 25% when applied correctly, it is one of the most effective and cost-efficient weed management tools available for leguminous crop farmers.

How Imazethapyr 10% SL Works

This herbicide works by inhibiting the enzyme Acetohydroxyacid Synthase (AHAS), also known as Acetolactate Synthase (ALS), which is essential for the biosynthesis of branched-chain amino acids — specifically valine, leucine, and isoleucine — inside plant cells. Without these amino acids, the weed cannot synthesize the proteins it needs for cell growth and division. The active ingredient is absorbed through both leaf surfaces and root systems and then translocated throughout the entire plant via both the xylem and phloem, accumulating in the meristematic growing regions where it disrupts DNA synthesis and stops new growth completely. Weeds stop growing within hours of application, and complete weed death typically follows within 7 to 14 days.

Why Farmers Choose This Herbicide

One of the most appreciated qualities of Imazethapyr 10% SL is its truly broad-spectrum activity, effectively controlling annual grasses, broadleaf weeds, and sedges all in one spray. This means farmers managing mixed weed populations — a very common situation in soybean and groundnut fields across India — don’t need to apply multiple herbicides for different weed types, saving both time and input cost per application.

This herbicide also offers valuable residual soil activity, meaning it continues to control newly germinating weeds for a period after the initial spray, not just the weeds already present at the time of application. This extended protection gives the crop a longer weed-free window from a single spray, reducing the overall number of herbicide applications needed across the season. Farmers may notice a temporary “Yellow Flash” on crop leaves after spraying — this is a normal, temporary response that fully resolves within 10 to 14 days without any yield loss, and is simply a sign that the product has been absorbed and is active. Because Imazethapyr 10% SL has some soil residual activity, farmers should follow proper crop rotation guidelines and avoid planting sensitive crops like mustard or vegetables in the immediately following season — wheat, gram, or chickpea are safer rotation options.

Key Benefits

• Controls annual grasses, broadleaf weeds, and sedges in one spray
• Proven to increase legume yields by up to 25% when applied correctly
• Absorbed through both roots and leaves for complete weed control
• Residual soil activity extends weed-free protection after spraying
• Reduces manual weeding costs by up to 80% per season
• Single application covers the critical early weed-competition window
• Cost-effective due to low application rate and broad-spectrum coverage

Why Crop Nutrition Matters Alongside Weed Control

With weeds removed and the crop given full access to soil nutrients and water, proper nutritional support helps the crop take full advantage of that weed-free window. Products like Humic Acid 98% Flakes help build stronger roots and improve soil nutrient availability during early establishment, while Power PGR Liquid supports better flowering and pod or fruit development as the crop moves toward harvest.

Safety Tips & Precautions

• Apply early post-emergence when weeds are at the 1 to 2 leaf stage, or 7 to 14 days after sowing, for best results
• Add a non-ionic surfactant (NIS) at 0.25% to 0.5% to improve absorption on waxy-leaf weed species
• Do not mix with fungicides or insecticides unless specifically recommended on the product label
• Do not apply if heavy rain is expected within 4 hours of spraying
• Follow crop rotation guidelines — avoid planting mustard or vegetables in the immediately following season
• Wear gloves, goggles, mask, and protective clothing while mixing and spraying
• Avoid direct contact with skin and eyes during application
• Use a flat-fan or flood jet nozzle sprayer for even, uniform coverage
• Wash hands and exposed skin thoroughly with soap after spraying
• Keep away from children, animals, and food or feed storage areas

Storage Instructions

Store Imazethapyr 10% SL in a cool, dry place away from direct sunlight and moisture. Keep the container tightly sealed and out of reach of children and animals.
