Description and Significance
Cucurbit yellow stunting disorder virus, CYSDV, can infect members of the family Cucurbitaceae, including all types of melons, summer and winter squash, pumpkins, gourds, and cucumbers [1]. CYSDV symptoms develop first in older leaves and mimic water stress. Intervenial chlorosis, a yellowing between the veins, streaks the leaves. In certain varieties, small green spots may develop on the leaves as well. As the plant’s internal transport system breaks down, it begins to drop its older leaves in attempt to preserve itself. Without enough leaves, the plant’s strength dwindles and it no longer can support or nourish its fruit. As a result, the fruits are smaller, not as sweet, and don’t ship or store as well [1]. Consequently, CYSDV has significant economic implications on national and international agriculture. However, control is difficult because there is no chemical or biological control suitable to fight the virus. Increasing water and fertilizer, and early season insecticide application (to reduce the virus’s vector population) may help, but these remedies compromise the producer’s ability to grow a sustainable crop and are incredibly costly [1].
