molecular lab

for the world class farmer

Nucleic acid-based diagnostic techniques are the methods of detecting sequences of the Fungal/Viral/Bacterial pathogen DNA in our molecular lab, Genetics Americaâ„¢. These methods provide greater speed, specificity, sensitivity, reliability, and reproducibility of the results obtained.

Real-Time qPCR as leading diagnostic technique applies for detection, identification and quantification of pathogens present in the infected plants, propagative plant materials and post-harvest produce.

Verticillium wilt

Fungal parasites can have enormous negative consequences for crop production. Their infections represent the invasion of plant tissues by one or more species of fungi.

The AGNEMA testing laboratory is particularly active in the screening and testing of soil, plant and irrigation water specimens for the agricultural industry, commercial growers, golf courses and the public.

Fire blight (Erwinia amylovora)
Bacterial canker / Blister spot (Pseudomonas syringae)
Crown gall (Agrobacterium tumefaciens)
Bacterial Wilt (Xanthomonas campestris)

Bacteria cause significant economic losses by infecting plants. The bacterial diseases basis many symptoms like wilts, rots, galls dwarfing, cankers, leaf spots, discoloration of plants parts, etc. Like viruses, the timing of questioning symptoms by collecting samples and detecting pathogens, is crucial to control/manage disease. Molecular diagnostics of bacteria has been known as high-end method to detect and identify them.

Emerging and prevalent bacterial diseases do not have a practical cure and methods of disease management and control are limited to deterrence thus when it comes to bacterial issues, follow strategy of start clean and stay clean!

RT-qPCR testing on nematodes that transmit virus

Some nematodes transmit viruses while feeding on roots, the consequence of viral diseases evaluate much higher than their direct yield loss. 

Dagger nematodes (Xiphinema sp. - Americanum Group)

  • Cherry Raspleaf Virus
  • Tobacco Ringspot Virus
  • Tomato Ringspot Virus
  • Grape fanleaf Virus

Stubby Root nematode (Paratrichodorus sp. & Trichodorus sp.)

  • Tobacco Rattle Virus
