Abstract Fusarium wilt of sesame is one of the main, destructive diseases of this crop in most countries and Egypt. Fussarium oxysporum f. sp. sesami is the causal pathogenic fungus. The interrelation ship between the causal organism and sesame rhizosphere was studied. Agricultural practices, i.e., date of sowing, varietal susceptibility, fertilizer and fungicidal treatment were investigated to minimize disease incidence. First June is the best dates of sowing reduced percentage of infection, disease severity and gave higher yield of sesame seeds. Half recommended dose or NPK gave a less percentage of infection, disease severity and gave higher yield. Normal recommended dose of micro elements gave a less percentage of infection, disease severity and gave higher yield. 62.5 kg feddan agriculture sulphur added to the soil before sowing reduced the percentage of infection, disease severity and gave a higher yield of sesame seed. Biocontrol agents bacteria (Bacillus spp.), Fungi (Aspergillus spp. and Trichoderms spp) and Streptomyces spp. were studied by using petri-dish streptomyces. |
