Reaction of melon genotypes to Didymella bryoniae (Fuckel) Rehm

Determination of fungal root and stem rot agents of melons grown in Kumluca/Antalya

“…In the greenhouses, 100 randomly selected melon plants were examined among approximately 2500 plants in each greenhouse with 1 decare of land, to determine disease incidence and severity rates (%). Disease severity on melon plants was scored by using 0-4 scale modified from Santos et al (2017), where; 0: no visible symptoms, 1: <1 cm diameter soaked lesion on the plant stem or slight wilting, 2: >1 cm diameter soaked lesion on the plant stem or moderate wilting, 3: partially necrotic lesion on the plant stem, with severe wilting of the plant, and 4: complete necrosis with total…”

“…Agar pieces with pathogen mycelia taken from the growing cultures were placed on the stem of the melon seedlings near cotyledones with sterile toothpicks. Plants were kept in a moisture chamber for 72 hours and disease severity evaluations were made 7, 14 and 21 days after inoculations using a 0-4 scale (Santos et al 2017).…”

“…Fungal pathogens are especially important among the factors causing losses in melon production. Didymella bryoniae, Fusarium spp., Macrophomina phaseolina, Monosporascus cannonballus, Podosphaera xanthii, Pythium spp., Rhizoctonia solani and Verticillium dahliae are among the most common fungal pathogens isolated from melons (Reuveni et al 1982;Aegerter et al 2000;Santos et al 2017).…”
