ABSTRACT

The soil is the primary supply of food and energy for all living things. The soil is an inordinate source of microorganisms and they carry out one of the major duties of soil that is to start and enhance the growth of plants and crops. However, the harvests are often harmed and spoilt by plant infections in a large region that grows under ideal circumstances and during climate change. The most of the recent work has undertaken using soil bacteria to fight against plant infections. This might infer that, pathogenic fungi are the primary cause of many diseases that result in considerable output losses. The crop growers frequently employ synthetic fungicides to both avoid and treat plant diseases. The multiple available forms of fungicides have been overused and used carelessly, causing environmental damage. Therefore, there is a high growth in industries which provide agricultural goods that have been grown naturally, without the usage of chemical fertilizers or pesticides. In the present research one of the biological approaches is explored to resist the growth of fungal plant pathogen. The various soil bacterial strains were isolated from the maize crop and tested to possess antimicrobial activity against Aspergillus genus strain, which is potent plant pathogen of tomato. Aspergillus causes Black rot diseases to tomato and so the fungal sample was isolated from the rotten tomato. To observe the antifungal properties against Aspergillus the trichoderma, pseudomonas etc… bacterial strains were used. The findings of study revealed that Staphylocoocus, Streptococus and Psedomonas were capable to posses the high potential to resist and cidal activity against Aspergillus.
