Potato viruses of 7 commercial cultivars grown in field Primorsky Krai of Russia
Овощи России, 2022 Scientific relevance. Plant viruses cause a significant economic loss to potato production, especially if plants are infected at early growth stages and infections are mixed. Viral diseases reduce both yield and quality of harvested crops.

Matching methods to produce maps for pest risk analysis to resources [PDF]
, 2013 Decision support systems (DSSs) for pest risk mapping are invaluable for guiding pest risk analysts seeking to add maps to pest risk analyses (PRAs). Maps can help identify the area of potential establishment, the area at highest risk and the endangered ...
