Fungal plant pathogens are a group of microorganisms that show a very high versatility during their infection cycles. This versatility allows them to infect a wide variety of crops. They employ diverse strategies to infect and colonize the plants, and they also establish a complex interaction between fungus species and their hosts. Common strategies of phytopathogenic fungi include forming specialized infection structures (haustoria and appressoria, etc.). In Japan, Rahman et al. studied of the pathogenicity of Alternaria tenuissima isolates, collected from broad bean, on four broad bean cultivars. Two isolates of Alternaria tenuissima failed to produce lesions and two other isolates were less virulent. Gherbawy studied the pathogenicity of Alternaria species collected from several Egyptian crops on tomato fruits. 62% of isolates were pathogenic to wounded tomato fruit. Tuohy et al.examined the pathogenic variation of Drechslera teres f. teres and D. teres f. maculate, the causal agent of net and spot blotch disease of barley.
