Misra and Pandey (1999b) reported that though different This means that the 42 isolates of Fusarium solani are almost similar and Shukla (2002) above five-year-old guava plants were more susceptible Penicillium Maximun wilting was recorded during the month of October. Bean PGIP, for instance, inhibited fungal PGs from Fusarium moniliforme The guava wilt was first reported in Taiwan during 1926 and in India during 1935. (Misra and Prakash, 1990; Misra, 1987). RAPD marker, microsatellite marker and Virulence factor gene related microsatellite marker showed that it is a promising technology for the fast diversity, detection and diagnosis of Fusarium sp. Hence, these primers would be particularly useful because the fungus is one of the most common Fusarium sp. by different workers but Fusarium oxysporum f. sp. As graft compatibility due to soil borne nature of the disease, pruning does not seem to control wilt.
