Godrej Richesa Pyroxasulfone 85% WG Herbicide for Wheat, Maize & Soybean

Godrej Richesa Pyroxasulfone 85% WG Herbicide

Godrej Richesa Pyroxasulfone 85% WG is a selective pre-emergence herbicide from Godrej Agrovet, designed to manage specified annual grassy and broadleaf weeds in wheat, maize and soybean. It contains Pyroxasulfone 85% in water-dispersible granule formulation, which acts primarily in the soil to control susceptible weeds during germination and emergence.

Richesa helps reduce early weed competition for sunlight, nutrients, water and growing space. Pyroxasulfone inhibits the synthesis of very-long-chain fatty acids required for normal cell growth in emerging weeds. It is particularly relevant to early weed management in wheat fields affected by susceptible Phalaris minor (Gulli Danda), subject to the approved product label.

Product Details

Key Features and Benefits

• Early Weed Control: Targets susceptible weeds during germination before they become established.
• Controls Annual Grasses: Helps manage specified grassy weeds, including Phalaris minor in wheat.
• Broadleaf Weed Management: Provides activity against certain susceptible annual broadleaf weeds.
• Residual Soil Activity: Helps suppress subsequent germination of susceptible weeds for a period determined by soil and environmental conditions.
• Reduces Crop Competition: Early weed control helps preserve water, nutrients and growing space for the crop.
• Convenient WG Formulation: Water-dispersible granules can be mixed with water for uniform spray application.

Recommended Crops and Target Weeds

1. Wheat

Pyroxasulfone 85% WG is used for managing Phalaris minor, commonly known as Gulli Danda or Little Seed Canary Grass. This weed can compete strongly with wheat during early crop development.

2. Maize

Published recommendations for the same technical formulation include susceptible weeds such as Echinochloa crus-galli, Eleusine indica and Phyllanthus niruri.

3. Soybean

Published recommendations include Echinochloa colona, Celosia argentea, Trianthema portulacastrum, Amaranthus viridis and Digera arvensis.

Important: These weed examples are derived from Indian technical-formulation references. Confirm the precise crop-weed combinations on the current Godrej Richesa label before application.

How Does Godrej Richesa Work?

Pyroxasulfone belongs to HRAC Group 15 and inhibits the formation of very-long-chain fatty acids in susceptible weeds. These fatty acids are essential for normal cell membrane development and growth.

The herbicide acts primarily on germinating weeds through their developing shoots and roots. By disrupting normal growth processes, it prevents susceptible seedlings from establishing successfully.

Richesa is mainly a soil-applied pre-emergence herbicide. It should not be expected to control large, established weeds in the same way as a conventional post-emergence foliar herbicide.

Dosage and Application Method

Manufacturer-Specific Dosage: The publicly accessible Godrej Richesa product page does not display a numerical dose. Follow the original Godrej product label and Directions for Use for the appropriate crop-specific quantity.

Technical Reference for Wheat: An ICAR-IIWBR advisory describes Pyroxasulfone 85% WG at 60 g per acre for Phalaris minor management in wheat, with specific application timings. This is a formulation-level reference and not independent confirmation of the Godrej Richesa product label.

Application Method: Apply using a calibrated agricultural sprayer with a suitable flat-fan nozzle to distribute the spray uniformly over the recommended treatment area.

Application Instructions

1. Confirm the crop, weed and application timing on the original product label.
2. Prepare a reasonably level seedbed before treatment.
3. Measure the recommended quantity using appropriate measuring equipment.
4. Mix the granules with a small quantity of clean water and stir thoroughly.
5. Add the mixture to the spray tank and fill with the remaining required water.
6. Maintain agitation to keep the spray mixture uniform.
7. Apply evenly to the soil using the recommended nozzle and spray volume.
8. Follow the labelled instructions regarding soil moisture, irrigation and subsequent cultivation.

Best Time for Application

Pyroxasulfone is generally used before susceptible weed seedlings emerge. Application timing depends on the approved crop-specific directions.

For wheat, published Indian agricultural guidance discusses application soon after sowing as well as a specified later timing before the first irrigation. These timings should not be transferred automatically to other crops or brands without checking their registered labels.

Adequate soil moisture is important for herbicide activation. Avoid spray drift, excessive runoff and application under unsuitable weather conditions.

Important Precautions

• Use only on crops and weeds approved on the current registered product label.
• Do not apply to unrelated crops or unapproved varieties.
• Follow the specified sowing depth and crop-establishment precautions.
• Avoid overlapping spray passes and excessive dosage.
• Prevent spray drift or runoff into nearby sensitive crops and water bodies.
• Wear protective gloves, suitable clothing and eye protection.
• Avoid inhaling spray mist and contact with skin or eyes.
• Do not mix with other agrochemicals without confirming compatibility and approval.
• Observe crop rotation and following-crop restrictions.
• Rotate herbicide modes of action as part of resistance management.
• Store in a dry, secure location away from children, food and animal feed.
