| Abstract | ||
| This study was conducted to evaluate the efficiency of three inoculation methods (spraying the flowering inflorescence with fungal suspension, stalk injection, and soil contamination with fungal suspension) with Fusarium nygami isolates FNK2 and FNK14 on the systemic infection of sorghum and seed transmission under field condition. Results showed significant differences between inoculation methods with Fusarium nygami isolates FNK2 and FNK14 separately in systemic and seed infection with the two isolates except that of soil contamination with spore suspension of the two isolates, where no significant differences compared with control treatment. spraying the flowering inflorescence with fungal suspension was found to be more efficient than the other methods,with percentage of seed infection 48.5 and 40% in spring season, 52and 61% in fall season for two isolates respectively compared to zero infection in control treatment in both seasons.The three inoculation methods caused significant decrease in dry weight of plants , 62 - 96 g / plant, 74 -105 g / plant in spring seasons, 53-87 g / plant,64 -95 g / plant in fall for the two isolates respectively , compared with 124 g / plant and 112 g /plant in control plant for the two seasons respectively. | ||
