Abstract
The study results has shown efficiency of chemical fungicide Ticghazole in concentration (0.25 , 0.5) ml/L by increasing germination percentage that reaches (46, 49.2)% respectively compared with control treatment that was 9%, the same concentrations lead to reduce damping–off percentage from 57% in control treatment to (12,10)% in seeds that was treated with chemical fungicide in concentration (0.25 , 0.5) ml/L respectively. Experimented concentrations of bio-cidal Bacillin exhibited ability in seeds perfect from damages of pathogenic fungus by increasing seeds germination percentage to (61.9, 63.8)% when it used in concentration (0.25 , 0.5) gm/L water respectively and in the same time not occur any germination case in not treatment seeds with bio-cidal Bacillin solution , the same concentrations lead to reduce damping–off percentage to (6.0, 5.0) % respectively when it was increased to 57% in control treatment. Integration treatment between bio-cidal Bacillin and chemical fungicide Ticghazole give highest germination percentage that was 65.7% in Bacillin treatment and 51.4% in Ticghazole treatment, was damping–off percentage reduce to 5.0% in Integration treatment when it was increased to54.0% in control treatment, Integration treatment no differ significantly compared with Bacillin and Ticghazole treatments when they were using singly , study results has shown Bacillus cereus population density was 1×105cell/ gm in root growth region of Bacillin treatment and population density of same bacteria reduce to 5×106 cell/ gm in interference treatment between Bacillin and Ticghazole .
