Adaca - Pyroxasulfone 85% w/w WG - ADAMA

ADAMA Adaca Pyroxasulfone 85% WG Herbicide

ADAMA Adaca is a selective pre-emergence herbicide containing Pyroxasulfone 85% WG. It is registered in India for specified weeds in wheat, maize and soybean. The former “Adasa” spelling and paddy claim on this listing were incorrect; the product pack and ADAMA India identify the trade name as Adaca.

Adaca belongs to HRAC/WSSA Group 15 (legacy K3), the inhibitors of very-long-chain fatty-acid synthesis. Correct soil condition, placement and application timing are important for pre-emergence activity. Follow the current product label as the final authority.

Why Choose Adaca?

• Pre-emergence timing: Designed to manage listed weeds before they establish and compete strongly with the crop.
• Labelled for three crops: Registered directions cover wheat, maize and soybean with crop-specific weed lists.
• Wheat focus: ADAMA specifically positions Adaca for management of resistant Phalaris minor in wheat.
• Clear mode-of-action group: HRAC Group 15 identification supports informed resistance-management planning.
• Concentrated WG formulation: Water-dispersible granules allow precise measurement; the current listing contains a 60 g pack.

Technical Specifications

How It Works

1. Pyroxasulfone is absorbed mainly by emerging weed roots and moves upward in the xylem.
2. It inhibits synthesis of very-long-chain fatty acids needed for normal cell and shoot development.
3. Susceptible seedlings fail to develop normally, helping prevent the listed weeds from establishing.

This mechanism does not make Adaca suitable for every weed or crop. Apply only at the label-approved timing and on the listed crops.

Registered Crops, Weeds and Application Guide

Use the supplied label as the final authority. Rates below are per hectare. Do not convert them to a per-litre or per-acre dose without an approved basis.

PHI means pre-harvest interval: the minimum waiting period between application and harvest.

Application Best Practices

• Timing: Apply at the pre-emergence stage stated on the supplied label. It is not a rescue treatment for large, established weeds.
• Seedbed and soil: Prepare and treat the field according to label directions; soil condition and placement influence pre-emergence performance.
• Measurement: Use calibrated weighing and spraying equipment. Do not estimate the gram quantity.
• Coverage: Use the prescribed water volume and maintain even application without overlaps or gaps.
• Crop safety: Do not apply to paddy or any unlisted crop, and do not change timing, dose or placement.

Resistance Management

• Adaca is HRAC Group 15. Repeated reliance on one mode of action can select resistant weeds.
• Use cultural and mechanical weed-management practices where practical.
• Plan rotations with effective herbicides from a different HRAC group only when labels and local recommendations allow.
• Do not treat another Group 15 product as a resistance-rotation partner.
