PCL Agrolife Stopper Pendimethalin 38.7% CS Herbicide

PCL Agrolife Stopper Pendimethalin 38.7% CS Herbicide

PCL Agrolife Stopper is a selective herbicide containing Pendimethalin 38.7% CS, developed for controlling susceptible annual grassy and broadleaf weeds during germination. Its soil-active formulation helps prevent weed establishment and reduces early competition between crops and weeds for nutrients, moisture and growing space.

Stopper uses a capsule suspension (CS) formulation containing Pendimethalin, a Group 3 herbicide. Pendimethalin 38.7% CS is recommended in Indian agricultural label guidance for weed management in soybean, cotton, chilli and onion. Follow the original Stopper label for product-specific crop approvals and directions.

Key Benefits of Stopper Herbicide

• Early Weed Control: Helps prevent the establishment of susceptible weeds during germination.
• Grassy Weed Management: Controls susceptible annual grasses, including certain Echinochloa and Digitaria species.
• Broadleaf Weed Management: Provides activity against susceptible broadleaf weeds such as Amaranthus and Portulaca species.
• Residual Soil Activity: Works in the treated soil layer to suppress susceptible emerging weeds.
• Reduced Crop Competition: Early weed suppression helps protect crop access to moisture, nutrients and growing space.
• Capsule Suspension Formulation: Contains Pendimethalin in a capsule suspension formulation for soil-active weed management.

How Does PCL Stopper Herbicide Work?

Pendimethalin belongs to HRAC Group 3, a class of herbicides that disrupt microtubule assembly in susceptible plants. Microtubules are essential for normal cell division and growth.

When susceptible weeds begin germinating in treated soil, Pendimethalin interferes with normal seedling development. This prevents many affected weeds from establishing successfully.

Stopper is intended for early-stage weed management. It does not provide reliable control of well-established weeds or perennial weeds. Correct application timing and soil conditions are important for effective results.

Recommended Crops and Target Weeds

Indian government label information for Pendimethalin 38.7% CS identifies the following crop and weed combinations. Confirm that each use appears on the current PCL Stopper label before application.

Dosage and Application Guidance

Indian government label information for Pendimethalin 38.7% CS provides a formulation dosage of 1500–1750 ml per hectare, approximately 607–708 ml per acre, with 500 litres of water per hectare for specified applications in soybean, cotton, chilli and onion.

Product-Specific Verification: These are formulation-level reference rates, not independently confirmed PCL Stopper label directions. Confirm the correct crop, application rate, timing and water volume from the original Stopper container or leaflet before use.

Application Method: Pendimethalin 38.7% CS is used for early-stage soil-active weed control. Apply only at the crop stage and under the soil conditions specified on the registered product label.

Uniform application over the intended soil area is important. Avoid disturbing the treated soil layer unnecessarily, and follow all instructions concerning irrigation, soil moisture and subsequent crop operations.

When Should You Use Stopper?

Stopper is intended for use before susceptible weeds become established, following the crop-specific application timing on the original label.

Because Pendimethalin primarily acts during germination and early seedling development, it should not be selected as a general post-emergence treatment for fully grown weeds.

Frequently Asked Questions

1. What is PCL Stopper Herbicide used for?

Stopper is a Pendimethalin 38.7% CS herbicide used for managing susceptible annual grassy and broadleaf weeds during germination.

2. What is the composition of Stopper?

PCL Stopper contains Pendimethalin 38.7% CS in a capsule suspension formulation.

3. What is the dosage of Pendimethalin 38.7% CS per acre?

Indian government label guidance specifies approximately 607–708 ml per acre for certain approved crop uses. Follow the current PCL Stopper label for its exact dosage.

4. Can Stopper control grassy and broadleaf weeds?

Yes. Pendimethalin controls susceptible annual grassy and broadleaf weeds during their germination stage.

5. Does Stopper kill already-grown weeds?

Pendimethalin mainly acts on germinating weeds and is not intended for controlling established weeds.

6. What is the difference between Pendimethalin 38.7% CS and 30% EC?

Both contain Pendimethalin, but they have different concentrations and formulations. The 38.7% CS formulation uses capsule suspension technology, while 30% EC is an emulsifiable concentrate. Their application rates must not be interchanged.

Note: Follow the original registered PCL Stopper label for approved crops, target weeds, dosage, application timing, waiting periods and safety precautions. Avoid spray drift and contamination of water bodies. Incorrect herbicide use may damage crops or result in poor weed control.
