Plant viruses are significant threats to cucurbit production in Jordan, with symptoms observed during surveys in September 2022 indicating infections correlated with high whitefly populations.
A total of 80 leaf samples from various cucurbits were analyzed, revealing the presence of multiple viruses, including the squash vein yellowing virus, across symptomatic samples without detection in asymptomatic ones.
Molecular approaches confirmed the presence of several RNA and DNA viruses, but none were found in healthy samples, highlighting the impact of these pathogens on cucurbit crops.
