Data from: First Report of Squash vein yellowing virus in Watermelon in Guatemala

    Watermelon (*Citrullus lanatus*) and other cucurbits are important crops grown in Guatemala for local consumption and export. Four samplings of crowns, peduncles, and/or leaves of symptomatic plants were made in March and April 2015. Total RNA was extracted from symptomatic plant tissue and tested by RT-PCR for SqVYV, CYSDV, PRSV, and/or begomoviruses. This is the first report of SqVYV infecting watermelon in Central America.
