PI Bunker is a selective pre-emergence herbicide that controls major grasses, broadleaf weeds, and sedges. Bunker herbicide works by inhibiting root and shoot development of susceptible weeds, helping reduce early crop-weed competition. PI Bunker is suitable for wheat, transplanted rice, cotton, and soybean crops. Bunker PI herbicide forms a thin layer on the soil surface after application. This helps prevent weed seeds from germinating and supports cleaner crop establishment. Bunker herbicide performs best when applied at the recommended stage with adequate soil moisture.
Key Features and Benefits of PI Bunker Herbicide:
Broad-Spectrum Control: Bunker herbicide controls important grassy, broadleaf, and sedge weeds.
Pre-Emergence Action: PI Bunker is applied before weeds emerge, which helps to stop the development of the weeds.
Root and Shoot Inhibition: Bunker PI herbicide interferes with root and shoot growth of susceptible weeds.
Residual Activity: Bunker herbicide provides residual weed suppression after application, which means it lasts for a longer period.
Better Crop Growth: Bunker herbicide reduces early weed competition for nutrients, moisture, and sunlight.
Bunker Herbicide Uses:
Bunker herbicide uses include controlling important annual grassy, broadleaf, and sedge weeds in major field crops.
Grassy Weeds: Phalaris minor, Echinochloa colona, Echinochloa crus-galli, Eleusine indica
Broadleaf Weeds: Chenopodium album, Amaranthus viridis, Portulaca oleracea, Trianthema spp.
Sedge Weeds: Cyperus difformis, Cyperus spp.
Bunker Herbicide Dose:
Apply PI Bunker as a pre-emergence treatment with sufficient water and proper soil moisture. The application rate varies with crop and soil type.
Crop | Target Weeds | Dose / Acre | Per Litre | Per 15L Pump |
|---|
Wheat | Phalaris minor, Chenopodium album, Melilotus alba and other annual weeds | 1.34–2.02 L | 4.8–7.3 ml | 72–109 ml |
Rice | Echinochloa colona, Echinochloa crus-galli, Fimbristylis miliacea, Cyperus difformis and others | 1.34–2.02 L | 4.8–7.3 ml | 72–109 ml |
Cotton | Echinochloa spp., Amaranthus viridis, Eleusine indica, Trianthema spp. and others | 1.01–1.69 L | 3.6–6 ml | 54–90 ml |
Soybean | Echinochloa spp., Amaranthus viridis, Portulaca oleracea, Eleusine indica and others | 1.01–1.34 L | 3.6–4.8 ml | 54–72 ml |
General Dose: Use Bunker PI herbicide according to the crop-specific rate, soil type, and recommended water volume. The rates above are converted from the manufacturer's hectare-based recommendations.
How to Use PI Bunker:
Prepare a fine, level seedbed before application.
Measure the required quantity of PI Bunker according to the crop and soil type.
Fill the spray tank partly with clean water.
Add the measured Bunker herbicide while mixing continuously.
Add the remaining water and mix thoroughly.
Spray uniformly over the soil surface.
Use a suitable flat-fan nozzle for even distribution.
Maintain adequate soil moisture after application.
For transplanted rice, maintain the recommended standing water conditions after treatment.
Best Time to Apply:
Apply Bunker PI herbicide before weed emergence. In wheat, application is recommended immediately after sowing. For transplanted rice, apply before weeds emerge while maintaining a uniform puddled field. Cotton can be treated before planting or as a pre-emergence application according to the recommended method.
Timely application of Bunker herbicide helps prevent weeds from becoming established and competing strongly with the crop.
Frequency of Application and Compatibility:
Frequency of Application: PI Bunker is generally used as a single pre-emergence treatment during the early weed-management stage.
Application: Apply Bunker herbicide uniformly across the soil surface using a suitable sprayer.
Soil Moisture: Adequate soil moisture is important for proper performance of Bunker PI herbicide.
Compatibility: Avoid indiscriminate tank mixing. Conduct a jar test before combining PI Bunker with other herbicides or agricultural inputs.
Safety Precautions and Handling:
Wear gloves, protective clothing, eye protection, and a suitable mask while handling and spraying.
Avoid direct contact with the concentrate and spray solution.
Do not eat, drink, or smoke during mixing and application.
Avoid inhaling spray mist.
Spray in the direction of the wind.
Wash hands and exposed skin thoroughly after use.
Keep children and animals away from treated areas.
Prevent contamination of ponds, canals, wells, and other water sources.
Do not use the product in areas where aquaculture is practised along with rice cultivation.
