Pseudomonas spp., promising biocontrol agents against pre and post-harvest Fusarium wilt disease in Cucumis MELO L. Fruits

The enrichment of plant rhizosphere microorganisms as Fluorescent Pseudomonas is a strategy that enhances the vegetables production and control pre and post - harvest diseases. Three Pseudomonas spp., (P. fluorescence, P. putida, P. aeruginosa) and their combination are used as biofertilizer to increase the production of Cantaloupe and as biocontrol agents to control cantaloupe wilt disease caused by Fusarium oxysporum in field and after storage in comparing with Bravo 500 fungicide and blank control. All the treatments increased the plant parameters and decreased the disease incidence and severity% before and after storage. P. fluorescence increased the plant height, leaves no., dry weight, shoots no., fruits diameter and sugars content before and after storage. It also decreased disease incidence% in field and after storage. P. aeruginosa increased fruits weight after storage, chlorophyll a and fungus inhibition.
