IIL Pendamil Herbicide - Pendimethalin 30% EC for Pre-Emergence Weed Control in Rice, Wheat, Cotton & Soybean

IIL Pendamil is a selective pre-emergence herbicide marketed by Insecticides (India) Limited (IIL), containing Pendimethalin 30% EC. It is recommended for controlling susceptible annual grasses and broadleaf weeds in wheat, transplanted rice, cotton and soybean.

Sprayed on the soil right after sowing, Pendamil stops weeds before they come up, so the crop gets a clean start. It inhibits microtubule assembly and cell division in germinating weed seedlings, preventing normal root and shoot development. This reduces early weed competition and supports better crop establishment.

IIL Pendamil price starts at Rs. 255 for 500 ml, and the 1 litre pack is Rs. 470 against an MRP of Rs. 700. Below you will find the Pendamil dose per acre for wheat, crop-wise dosage, target weeds, pendimethalin 30 EC price and application instructions.

What is IIL Pendamil Used For?

IIL Pendamil is a Pendimethalin 30% EC pre-emergence herbicide used for controlling susceptible annual grasses and broadleaf weeds in wheat, transplanted rice, cotton and soybean.

For detailed information about pendimethalin, its chemical properties, mode of action and general agricultural uses, read our Pendimethalin Technical Guide.

Key Benefits of IIL Pendamil

• Pre-emergence control: acts on weed seeds as they germinate, before weeds appear above the soil
• Residual protection: keeps working in the treated soil layer during the early weed-competition window, typically the first 30 to 45 days after sowing
• Grasses and broadleaf weeds: controls susceptible annual grasses and broadleaf weeds, including Phalaris minor (Gulli Danda) in wheat
• Lower weeding cost: reduces the need for early hand weeding
• Better use of water and nutrients: the crop faces less early competition
• Suitable for key crops: wheat, transplanted rice, cotton and soybean
• Easy to apply: uses a standard knapsack or battery sprayer with a flat-fan or flood-jet nozzle

Weeds Controlled by IIL Pendamil

The manufacturer provides crop-specific weed recommendations. Target weeds vary by crop.

1. Weeds Controlled in Wheat

2. Weeds Controlled in Transplanted Rice

3. Weeds Controlled in Cotton and Soybean

The manufacturer's leaflet lists the same target weeds for both crops:

Weed-control performance depends on weed species, soil conditions, application timing and spray coverage. Pendamil is intended for pre-emergence weed management and should not be considered a post-emergence herbicide for established weeds.

How Does Pendamil Work?

Pendamil works in three short steps:

1. Spray on the soil after sowing. The EC liquid mixes with water and forms a treated layer on the top of the soil.
2. Weed seeds germinate in the treated layer. Their young roots and shoots absorb the pendimethalin.
3. Cell division stops. Pendimethalin inhibits microtubule assembly, so germinating weed seedlings cannot develop normal roots and shoots and fail to establish. Crop seeds are sown deeper, below the treated layer.

Pendamil does not control weeds that have already emerged. Apply it before weed germination, on moist soil, for best results.

IIL Pendamil Dosage – Dose per Acre, per Litre and per 15-Litre Pump

The recommended dose of IIL Pendamil (Pendimethalin 30% EC) depends on the crop and, in wheat, the soil type. The label dose is given per hectare; one hectare is about 2.47 acres.

Pendamil Dose per Acre for Wheat

Pendamil Dose per Litre and per 15-Litre Tank

These are approximate conversions based on about 200 litres of water per acre.

Important: These tank quantities are calculated examples, not separate manufacturer-specified tank doses. The total product quantity per acre must stay within the recommended crop and soil-specific rate. The manufacturer specifies 500–700 litres of water per hectare, equivalent to roughly 202–283 litres per acre. Adjust the tank calculation to your actual water volume and the area covered.

When to apply: immediately after wheat sowing, as a pre-emergence treatment, before weeds emerge.

All acre-wise quantities are approximate conversions from the manufacturer's hectare-wise recommendations (1 hectare = 2.471 acres). Follow the approved product label for the actual application rate.

When to Apply IIL Pendamil

Apply before susceptible weeds emerge. If weeds are already above the soil, Pendamil will not control them well.

Step-by-Step Usage Instructions

1. Prepare the field. Keep the soil level and free from large clods. Clods can leave gaps in the treated layer. The field should be weed-free at the time of spraying.
2. Check soil moisture. Pendimethalin is a soil-applied herbicide, so adequate soil moisture is important. Avoid treating completely dry soil without following the label's irrigation instructions.
3. Wear protective gear. Use gloves, a mask, goggles and full-sleeve clothing while measuring, mixing and spraying.
4. Mix the spray solution. Add the required dose of Pendamil to clean water and stir well. Use 500–700 litres of water per hectare (about 200–280 litres per acre).
5. Spray uniformly. Use a flat-fan or flood-jet nozzle and cover the whole soil surface without gaps.
6. Walk backward while spraying. This keeps your footprints from disturbing the treated soil.
7. Do not disturb the soil afterwards. Avoid ploughing, harrowing or other operations on the treated surface. Disturbing it can reduce the uniformity of weed control.
8. Clean the equipment. Wash all spray gear thoroughly with clean water after use.

Recommended Sprayers

• Knapsack sprayer
• Foot sprayer
• Compression knapsack sprayer
• Battery-operated compression knapsack sprayer

Tank Mixing and Compatibility

Do not assume that Pendamil is compatible with every herbicide, insecticide, fungicide or fertilizer. Before mixing, check the approved product label or get compatibility guidance from Insecticides (India) Limited. Do a small jar test first, mix only what you need for immediate use, and avoid unverified tank mixtures.
