Preliminary Study on the Control of Cucumber Green Mottle Mosaic Virus in Commercial Greenhouses Using Agricultural Disinfectants and Resistant Cucumber Varieties
Cucumber green mottle mosaic virus (CGMMV) is a re-emerging threat to greenhouse cucumber and other <i>Cucurbitaceae</i> crop production worldwide. This seed-borne virus can easily spread from a contaminated seeds to seedlings and to adjacent plants through mechanical contact of the foli...

The varieties ‘Jawell’, ‘RZ 22-551′, ‘Sunniwell’, ‘Bonbon’ and ‘Dee Lite’ were the most tolerant to CGMMV. They showed a high CGMMV infection level without compromising yield. These results proved the need for new productive cucumber varieties with CGMMV resistance.
