Paraquat Rapid Test Kit for Wheat, Corn, Soybean and Grain Screening

Not just a rapid test supplier — a long-term, globally proven food safety partner.

Fast screening for paraquat residues in grain, cereals, pulses, oilseeds and related agricultural commodities.

The Paraquat Rapid Test Kit provides a fast, simple and reliable front-end screening solution for grain processors, grain traders, feed manufacturers, food producers, exporters, laboratories, distributors, inspection authorities and quality control teams seeking to identify paraquat residue risks before laboratory confirmation, shipment or production use.

Suitable for incoming material inspection, supplier verification, export risk control, grain receiving, storage monitoring and food safety monitoring applications.

Product Principle & Result Interpretation

This rapid test kit is based on immunochromatographic assay technology and is designed for rapid qualitative screening of paraquat residues in applicable grain and agricultural matrices.

Results can be interpreted visually for routine front-end screening. Optional quantitative analysis is available for users requiring objective result interpretation, numerical result management, digital records and traceable QC workflow management.

The test is suitable for high-frequency screening in grain receiving stations, feed mills, food processing facilities, export preparation and laboratory pre-screening applications.

Why Screen for Paraquat Residues?

Paraquat is one of the most closely monitored herbicide residues in international agricultural trade.

Many importing countries, buyers and food companies maintain strict requirements regarding paraquat residues due to regulatory restrictions, food safety concerns and supplier qualification programs.

Grain processors, exporters, laboratories and inspection authorities routinely screen for paraquat residues to support:

• Export compliance management

• High-risk batch identification

• Supplier verification

• Grain receiving control

• Buyer specification compliance

• Feed safety management

• Food safety monitoring

• Shipment risk control

• Brand reputation protection

The detection of paraquat residues after shipment, buyer inspection or market release may result in shipment rejection, delayed clearance, buyer claims and significant financial losses.

Front-end rapid screening helps identify high-risk batches earlier and supports faster risk-control decisions before products enter storage, processing or international trade channels.
