Poster: Evaluation of Commercially Available Varieties of Yellow Squash and Zucchini for Tolerance to Cucurbit Leaf Crumple Virus in Georgia. Presented at the 2018 ASHS Conference by Timothy Coolong, Bhabesh Dutta, Alton Sparks and Rajagopalbabu Srinivasan. This was the first documented screening for this disease. Although some varieties of yellow squash performed better than others, yields were too low for them to be recommended when high levels of the disease are present. View the poster to learn more about the performance of yellow squash and zucchini varieties. View the poster.
