    Microbial seed coating was not significantly influenced germination percentage, germination index, or germination speed under laboratory conditions. Whereas, seeds coated with Trichoderma asperellum and Bacillus subtilis consistently demonstrated to improve seedling emergence and vigor in greenhouse conditions. With respect to disease suppression, coatings seeds with T. asperellum resulted to reduce both the incidence and severity of damping-off disease caused by Pythium torulosum. The lowest disease incidence (30.50%) and severity (17.43%) were observed in seedlings from T. asperellum-coated seeds. These findings highlighted the potential of antagonistic microbial coatings to promote seedling health and provided a sustainable strategy for managing soilborne diseases. This approach is offered a promising complement or alternative to chemical control methods in commercial tomato seedling production.

    The effects of the Bacillus probiotics powder, Bacillus subtilis 7 x 10<sup>6</sup> cfu g<sup>-1</sup> and Bacillus cereus 2.5 x 10<sup>7</sup> cfu g<sup>-1</sup> via dietary additional to control vibriosis disease in white shrimp culture for 14 days were evaluated. The results indicated that good recovery in shrimp fed with probiotic (T4) and the mortality reduced (86.7%), in comparison with the group without probiotics and with pathogen, Vibrio spp. (T3). In addition, it presented lower counts of Vibrio spp. than group fed without the probiotic causing a significantly reduced pathogen. Bacillus probiotics, B. subtilis and B. cereus had a better effect on hematological shown in the total haemocyte counts (THC) of the group with probiotic and with pathogen, Vibrio spp. (T4) had the highest THC every day throughout the experiment experiment followed by the group with probiotic and without pathogen (T2) respectively. Therefore, B. subtilis and B. cereus significantly enhanced the shrimps' ability to recover from Vibrio spp. infections and enhanced the quality of their cultures.
