Symptom-Based Panel

Yellowing Panel

About this product

The Yellowing Pathogen Panel™ is designed to test for pathogens associated with persistent yellowing and stalled growth when nutrient adjustments fail to correct symptoms, including chlorosis, vein clearing, and growth stagnation. This multiplex qPCR pathogen panel assay screens for Lettuce Chlorosis Virus (LCV), Beet Curly Top Virus (BCTV), and Hop Latent Viroid (HLVd) in a single test, reducing guesswork, cost, and diagnostic time.

  • Lettuce Chlorosis Virus
  • Beet Curly Top Virus
  • Hop Latent Viroid

The Yellowing Pathogen Panel™ is a multiplex molecular diagnostic assay developed to investigate infectious contributors to persistent chlorosis, vein clearing, and stalled growth that cannot be resolved through nutrition or environmental adjustment alone. These symptoms are frequently misattributed to nutrient deficiencies, leading to repeated feeding changes while underlying infections remain unaddressed.

This panel simultaneously detects:

  • Lettuce Chlorosis Virus (LCV), a viral pathogen associated with widespread yellowing and reduced photosynthetic capacity.
  • Beet Curly Top Virus (BCTV), which can cause chlorosis alongside deformation and stunting.
  • Hop Latent Viroid (HLVd), linked to reduced vigor, impaired growth, and chronic performance decline.

Using sensitive and specific qPCR technology, this panel provides reliable detection from a single sample with quick turnaround times. The Yellowing Pathogen Panel™ helps distinguish infectious causes of yellowing from nutritional or environmental issues, enabling informed, targeted corrective action.

Frequently Asked Questions

Everything you need to know to test your plants with us.

What are Plant Pathogen Panels™?

Plant Pathogen Panels™ are signal-based diagnostic panels designed around what growers actually observe in the crop.

Why are the panels signal-based instead of pathogen-based?

Growers see plant signals, not pathogens. Signal-based panels convert those observations into actionable answers.

How does a Plant Pathogen Panel™ work?

Send a sample, we decode the signal, and deliver clarity for a flat $18 panel.

What is included in each Plant Pathogen Panel™?

Each panel includes the three most relevant pathogen RT-qPCR tests for that signal.

What is the General Decline Pathogen Panel™?

Used when plants show overall decline without a clear cause.

What is the Wilting Pathogen Panel™?

Designed for plants that wilt despite adequate irrigation and environmental control.

What is the Leaf Deformation Pathogen Panel™?

Used when leaves twist, curl, or develop abnormal shapes.

What is the Mosaic Pathogen Panel™?

Designed for mosaic patterns, mottling, or irregular leaf coloration.

What is the Yellowing Pathogen Panel™?

Used when plants yellow without an obvious nutrient deficiency. Includes HLVd, Pythium, and Fusarium.

What is the Leafspot Pathogen Panel™?

Designed for leaves showing spots, lesions, or localized necrosis.

What is the Flower Failure Pathogen Panel™?

Used when flowers fail to develop properly or abort prematurely.
