Cucurbit Yellow Stunt Disorder Virus detected in Georgia on cucumber and cantaloupe

Cucurbit yellow stunt disorder virus (CYSDV) has been confirmed on cucumber and cantaloupe samples in GA.

Symptoms: Initial symptom starts with chlorotic (yellow) spotting, which gradually develops into a distinct interveinal chlorosis (yellowing). The veins of the leaf remain green but the rest of the leaf turns bright yellow giving an appearance as that of a nutrient deficient leaf.  As disease progresses, the leaves may roll upward and become brittle. Entire plant remain stunted. Fruit set can be severely affected.

Transmission: The virus is transmitted by Whitefly vector, Bemisia tabaci in a semi-persistent manner.
