Résumé en langage clair

Cucumber green mottle mosaic virus (CGMMV) is an increasing threat to global Cucurbitaceae crop production. Mechanical transmission is responsible for the quick spread of the virus throughout the commercial greenhouse environment. This may occur in the handling of plants, leaf-to-leaf contact, plant wounds made with cutting tools, farm equipment, chewing insects such as the cucumber leaf beetle, and pollinators such as honeybees. A few infected plants in a cucumber greenhouse can lead to infection of the entire crop, causing losses in cucumber production ranging from five per cent to 20 per cent at the end of the cropping cycle. High infection in the crop may force growers to terminate production in the early stages and hence reduce the overall profitability of their operations. In addition, infection may not be limited to the current crop but may also affect subsequent crops due to the long-term persistence of the virus on contaminated crop residues, greenhouse hard surfaces and soil or soil-less greenhouse substrates. To help determine potential solutions, a research team led by Dr. Oualid Ellouz developed a management program that utilizes rigorous sanitization and tolerant cucumber varieties to decrease the impact of CGMMV in commercial greenhouse cucumber production.
