Metolachlor Rapid Test Kit for Tobacco, Corn, Soybean & Crops | Pre-LC-MS/MS Residue Screening

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

The Metolachlor Rapid Test Kit is designed for fast on-site screening of metolachlor residues in tobacco, corn/maize, soybean and other agricultural commodities.

It is especially suitable for tobacco raw material QC, agricultural raw material intake inspection, crop residue screening and pre-LC-MS/MS risk control.

For tobacco companies, processors and agricultural QC teams, the real challenge is often not testing itself, but discovering a high-risk batch too late — after collection, blending, storage, processing or shipment.

This rapid screening solution helps users identify potential metolachlor residue risks earlier, so that high-risk batches can be separated, further confirmed, or prevented from entering downstream production.

Similar rapid screening workflows have already been applied in large-scale tobacco and agricultural screening environments by professional international users, where consistency, practical operation and reliable screening performance are critical.

Main Testing Matrices

Tobacco Applications — Priority Use Scenario

Metolachlor screening is especially valuable in tobacco-related quality control, including:

* Fresh tobacco leaves

* Cured tobacco leaves

* Tobacco raw material batches

* Blended tobacco samples

* Tobacco processing materials

Best suited for:

* Tobacco companies

* Tobacco raw material suppliers

* Leaf purchasing centers

* Tobacco processing plants

* Third-party QC laboratories

* Large agricultural screening programs

For tobacco, rapid screening helps identify potential residue risk before raw materials enter blending, storage or processing stages.

⸻

Core Field Crop Applications

Metolachlor is closely associated with large-scale agricultural crop systems. The kit can also support screening in important field crop matrices, including:

* Corn / Maize

* Sweet corn

* Soybean

* Peanut

* Cottonseed

* Sugar beet

* Sugarcane

These crops represent stronger commercial application potential because they are linked to large planting areas, raw material trade, feed supply chains and food processing industries.

⸻

Vegetable & High-Value Crop Applications

For selected applications, metolachlor screening may also be used in:

* Tomato

* Carrot

* Cucumber

* Melon crops

* Celery

* Radish

* Beans

* Leafy vegetables

These matrices are suitable for users who need targeted residue screening before laboratory confirmation.

⸻

Key Application Scenarios

1. Tobacco Raw Material Screening

For fresh tobacco leaves, cured leaves and tobacco raw material batches.

Helps tobacco companies and suppliers screen residue risk before purchasing, blending, storage or processing, reducing the possibility of high-risk materials entering production.

This is the most important positioning for Metolachlor rapid screening, especially for customers with strict internal residue control requirements.

⸻

2. Corn & Soybean Raw Material Intake

For corn/maize, soybean, soybean meal and related crop materials.

Helps grain processors, feed mills and agricultural trading companies screen incoming raw materials before warehouse acceptance or production use.

This is suitable for high-volume agricultural supply chains where fast batch-level decisions are needed.

⸻

3. Agricultural Residue Risk Control

For peanut, cottonseed, sugar beet, sugarcane and selected vegetables.

Helps QC teams identify potentially high-risk batches before sending samples for laboratory confirmation, improving daily screening efficiency and reducing unnecessary laboratory workload.

⸻

4. Pre-LC-MS/MS Screening

For laboratories, tobacco QC teams and agricultural processors handling many samples.

Rapid screening can help users first separate low-risk and high-risk samples, so confirmatory LC-MS/MS or GC-MS/MS testing can be used more efficiently.

The kit is not intended to replace laboratory confirmation. It is designed as a front-end risk control tool before laboratory testing.

⸻

Why Metolachlor Rapid Screening Matters

Metolachlor residue control is often handled through laboratory multi-residue methods. However, in real production and supply-chain management, laboratory testing alone may not be fast enough for daily batch decisions.

Rapid screening helps users:

* Detect residue risk earlier

* Improve tobacco raw material control

* Reduce delayed discovery after blending or processing

* Support faster intake decisions for corn and soybean

* Reduce unnecessary laboratory workload

* Build a more practical residue monitoring workflow

For professional users, this kit is not just a simple strip. It is a practical pre-LC-MS/MS screening tool for tobacco QC, agricultural raw material control and routine residue risk management.

Laboratory-Backed Screening Solution

We are not only a rapid test strip supplier.

Our strength lies in an integrated system covering:

* In-house R&D

* Large-scale manufacturing

* Colloidal gold rapid screening technology

* Independent laboratory verification

With our own laboratories equipped with LC-MS/MS and GC-MS/MS systems, we can evaluate how rapid screening results align with laboratory reference methods in validated applications.

This does not mean the rapid test replaces laboratory instruments. It means our rapid screening products are supported by laboratory-backed verification, matrix evaluation and long-term optimization.

This capability helps customers gain more confidence when using rapid screening as a front-end risk control tool.

Brand Trust & Real-World Validation

Proven in Professional Tobacco & Agricultural Screening Environments

Metolachlor screening requires more than a low-cost strip. Professional users care about whether the method can work consistently in real samples, real workflows and real production pressure.

Similar rapid screening workflows have already been applied in large-scale tobacco and agricultural screening environments by international corporate users, where operational practicality, screening reliability and result consistency are essential.

With 20+ years of rapid test manufacturing expertise, in-house R&D, large-scale production and laboratory-backed verification capability, we provide more than a product.

We provide a practical residue screening solution for tobacco companies, agricultural processors, QC laboratories and professional users who need reliable front-end risk control before laboratory confirmation.

READ RESULTS WITH NAKED EYES

NEGATIVE:

The Test Line (T) is the same as or darker than the Control Line(C). It is negative.

POSITIVE:

The Test Line (T) is lighter than the Control Line(C),or there is no Test Line. It is positive.

INVALID:Reference Line Fails to appear

Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for an invalid result.

Review the procedure and repeat the test with a new test kit. Stop using the test kit immediately if the problem

is not solved and contact your local distributor.
