Agdia Inc. has developed a highly sensitive, two-step PCR assay that detects several important Pospiviroids known to cause significant damage in ornamental, citrus and solanaceous crops. Agdia’s own conventional two-step reverse transcriptase PCR (RT PCR) is ideal for testing crops subject to phytosanitary restrictions and requirements. Fast and highly reliable, the Agdia Pospiviroid PCR will screen for the following viroid infections: Potato spindle tuber viroid (PSTVd), Tomato chlorotic dwarf viroid (TCDVd), Tomato apical stunt viroid (TASVd), Tomato planta macho viroid/Mexican pepita viroid (TPMVd/MPVd), Chrysanthemum stunt viroid (CSVd), and Citrus exocortis viroid (CEVd).
