The factor of gray mold, within so many economically-important vegetables, cause some important losses of productivity. This factor is especially encountered in productivity areas, which have insufficient ventilaton, in foggy and dewy places at flowering times, and in depots. That gray mold factor is able to survive for a long time in soil and large hostplant range of the factor make difficult to control this factor. Inadequacy of cultural precautions and the negative impacts of chemicals, which are used for struggling verbal diseases, on human health and nature, especially the fact that pathogens create endurance against chemicals; in spite of these, the situation that there is no effective and adequate method of struggling with disease of gray mold, turn the studies of alternative methods that also involves biological strrugle into prior subjects. In this study, it is used 12 bio-agent bacteria strains (2x Bacillus megaterium, 2x Bacillus pumilis, 2x Bacillus subtilis, 2x Pantoea agglomerans, 1x Pseudomonas fluorescens, 1x Paenibacillus polymxa, 1x Bacilius thuringiensis, 1x Bacilius cereus). These strains are defined in some previous studies according to oil acid esters, which are isolated by the under or upper parts of the soil’s wild or cultivated plants. This study is performed under an in vitro and conrolled setting, aiming to determine the impact of these bio-agents on B. cinerea, which cause the losses of productivity of eggplant seedlings. Five bacteria strains, which give the best results under in vitro setting, have been chosen for stem practices and; effectiveness of these bacterias have been measured under controlled setting.
In this study, it is determined that one strain – which pertain to Pseudomonas chlororaphis supsp. aurofaciens, and one Bacillus amyloliquefaciens strain are also effective in vitro setting to struggle with B.cinerea. As a result, it is determined that the most two effective bacteria strains can be used as a biocontrol agent for controlling the B.cinerea in eggplant farming.
