GSP Pendifix Pendimethalin 30% EC Herbicide – Pre-Emergence Selective Weed Control for Wheat, Rice, Cotton & More

GSP Pendifix is a pre-emergence selective herbicide formulated with Pendimethalin 30% EC. It is designed to be applied to the soil before weeds germinate, forming a protective layer that targets weed seeds during germination. This stops early weed competition and helps crops establish themselves cleanly in the critical early growth stages.

Pendifix controls a wide range of annual grassy and broadleaf weeds including Phalaris minor, Chenopodium album, Echinochloa colona, Echinochloa crusgalli, Cyperus difformis, Amaranthus viridis, Portulaca oleracea, Trianthema spp., and many others. It is suitable for major crops such as Wheat, Rice, Cotton, Soybean, Groundnut, Sugarcane, Pulses, Oilseeds, Spices, and Vegetables. Because it acts selectively, it targets only the weeds and leaves the main crop unaffected.

Being soil-active with long residual action, Pendifix reduces the need for repeated manual weeding, saving time and labour during the early crop season. It is available as a yellow liquid in an EC (Emulsifiable Concentrate) formulation and is made in India.

Key Benefits

• Broad-spectrum weed control: Effectively manages both grassy and broadleaf weeds like Phalaris minor, Echinochloa spp., Cyperus difformis, and Amaranthus viridis in one application.
• Pre-emergence protection: Applied before weeds appear, it stops weed seeds from germinating so your crop faces less competition from the start.
• Crop safety: Selective mode of action targets only the weeds, leaving the main crop healthy and unaffected.
• Long residual action: Provides extended weed suppression during the early critical growth stages of the crop.
• Saves time and labour: Reduces or eliminates the need for manual weeding, saving significant time and effort in the field.
• Versatile across crops: Suitable for a wide range of field and horticultural crops including wheat, rice, cotton, soybean, groundnut, and sugarcane.

How It Works

Pendifix works as a pre-emergence selective herbicide. When applied to the soil surface, it forms a protective layer that acts on weed seeds as they begin to germinate. The active ingredient, Pendimethalin, inhibits cell division in the emerging roots and shoots of weeds. This stops the weeds at the earliest stage, before they can grow above the soil and compete with your crop.

Because the herbicide stays active in the soil for a long period, it continues to suppress weed emergence during the critical early weeks of crop growth. Its selective nature means it affects only the targeted weed species while leaving the main crop unharmed, giving your crop a clean, weed-free start.

Recommended Dosage & Application

Pendifix is applied to the soil before weed emergence. The dosage depends on the crop and soil type. Follow the crop-wise dosage below:

Crop	Dosage per Acre
Wheat	1300 ml (Light Soil), 1700 ml (Medium Soil), 2 L (Heavy Soil)
Rice	1.3 to 2 L
Cotton	1 to 1.7 L
Soybean	1 to 1.3 L
Sugarcane	1300 to 1700 ml
Groundnut	1300 to 1700 ml
Chilli	1300 to 1700 ml
Onion	1300 to 1700 ml

For foliar application, use 1300 to 1700 ml of Pendifix per acre. Always follow the recommended dosage and do not exceed it.

When to Use

Pendifix should be applied as a pre-emergence herbicide, meaning it must be used before weed seeds germinate. The ideal time is within 0 to 3 days after sowing, before weeds appear above the soil surface.

For best results, ensure there is adequate moisture in the soil at the time of application, as this helps activate the herbicide. After application, do not disturb the soil for at least 10 days so the protective layer remains intact and effective against emerging weeds.

Step by Step Usage Instructions

1. Prepare the field and sow the crop as per your normal practice.
2. Ensure the soil has adequate moisture before spraying.
3. Measure the correct dosage of Pendifix for your crop and acreage as per the dosage table.
4. Mix the measured quantity of Pendifix with the recommended amount of water in a clean sprayer tank.
5. Apply the spray evenly over the soil surface within 0 to 3 days after sowing, before weed emergence.
6. Do not disturb the soil for at least 10 days after application.
7. Wear protective gear such as gloves, mask, and goggles while mixing and spraying.
