چکیده مقاله:
Damping-off disease caused by Phytophthora melonis is the most common disease of cucumber seedlings Cucumis sativus L.. To study the efficacy of ۸-hydroxy quinoline sulfate (Beltanol®) in control of cucumber damping-off disease, glasshouse experiments were carried out with six treatments at research stations in Tehran, Alborz, and Semnan provinces in Iran. Treatments included ۰.۳, ۰.۴, and ۰.۵ ml∙l-۱ of Beltanol as the experimental fungicide, metalaxyl+mancozeb (Rosalaxyl® WP ۷۲%; FRAC code ۳ + M۰۳) at ۲ g∙l-۱ as the standard fungicide along with inoculated and untreated and non-inoculated (healthy) controls. Cucumbers were cultivated from seed in trays, and treatments were applied twice. Once after seed sowing and second time at the ۲-leaf stage. Disease incidence was recorded at the ۴-leaf stage. Beltanol at ۰.۳ ml∙l-۱ had the least effect among fungicides, with nearly ۵۰% of treated plants showing signs of disease. Application of Beltanol at ۰.۴ and ۰.۵ ml∙l-۱ decreased disease incidence by ۵۹.۵۵ and ۶۴.۴۷% compared to the inoculated control, respectively. Rosalaxyl® performed better than Beltanol and reduced disease by ۸۳.۵۵%. However, to provide alternatives for proper fungicide rotations, Beltanol at the rate of ۰.۴ ml∙l-۱ may manage damping-off disease in cucumber.
