| Abstract | ||||
| Seeds of fifteen sugar beet (Beta vulgaris L.) cultivars were collected in 2018 and 2019 in Egypt and screened for their seed-borne mycoflora using deep-freezing blotter method. Among those fungi recovered from sugar beet seeds, a plant pathogen Fusarium moniliforme was the most dominant. Thus, it was tested for its pathogenicity and transmission against sugar beet plants. Green chemicals (antioxidants) and biological control agents were used for suppressing F. moniliforme in comparison with Fludioxonil/Mefenoxam (MaximXL 3.5% FS®; a chemical fungicide), Potassium silicate at concentrations (4, 6, 8, 10 and 12 ml/L), Nicotinic acid at concentrations (1, 5, 10, 15 and 20 mM/L), Trichoderma harzianum, T. hamatum and Bacillus subtilis were tested against F. moniliforme in vitro, in the greenhouse and in the field. The results assured that nicotinic acid at 5 mM/L, T. harzianum and T. hamatum and potassium silicate at 12 ml/L were the best treatments compared with the Maxim® fungicide (control). But nicotinic acid at 5 mM/L was the most effective among all treatments. | ||||
