    Abstract

    The genus Fusarium is one of the most economically important genera of fungi and includes many pathogenic species which cause a wide range of plant diseases. The fungus can be soilborne, airborne, or carried in plant residue, and can be recovered from any part of plants. Fusarium oxysporum in one of the most variable species withim the genus. The majority of the isolates causing vascular wilts are specific strains that infect only a small number of host plants and have been differentiated fro each other using the sub specific term formae specialis (f.sp.). For example, strain causing Fusarium wilt of tomato, spinach, and sweet potato are Fusarium oxysporum f. Sp. Lycopersici, F. Oxysporum f. sp. Spinaciae; F. Oxysporum Schlecht f .sp. batatas (Wr). Snyd. Et Hans, respectively. It also causing Fusarium crown and root rot of tomato (F. Oxysporum f. Sp. Radicis-lycopersici). Recently, Fusarium sp. Was found causing wood-decay and bark necrotic on Hevea rubber. A variety of beneficial microorganisms such as Nonpathogenic F. Oxysporum Penicillium oxalicum, P. Funiculosum P. Purpurogenum, Aspergillus nidulans, A. Orchraceus, Trichoderma harzianum, T. Hamatum, Gliocladium viren, Pythium oligandrum, nonpatogenik Binucleate Rhizoctonia, Pseudomonas fluorescens, and Bukholderia cepacia, Bacillus subtilis have been demostrated their potential as biocontrol agents against various Fusarium diseases. The mechanism induced by the biocontrol agents are induced resistance by increasing hydrolyzed enzyme such as chitinase, β-1,3 glucanase, and β-1,4 glucosidase activity and the production and release of fungi tonix materials which lead to reducing the inoculums potential of pathogen in plant, the competition in the rhizosphere and infection sites, renewed or prolomged cambial activity that led to the formation of additional secondary xylem, induced the formation of structural barrier that protected the inner root tissue from FORL invasion and prevented pathogen spread.
