Disease alert from Dr. Dutta, vegetable pathologist.

Cucurbit yellow stunt disorder virus (CYSDV) has recently 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.
