Guava (Psidium guajava L.) is an important fruit crop of subtropical countries and cultivated extensively throughout India, it is grown almost in all the states. Bihar has the largest area (24.7 thousand ha.) under guava cultivation followed by Uttar Pradesh (18.5 thousand ha.) and Maharastra (14.8 thousand ha.). Various pathogens have been reported from the wilt affected plants from guava orchards of Aligarh district, prominent among them is fungi Fusarium oxysporum f. sp. Psidii. In the present study, some biocontrol agents T. harzianum, T. virens, A. niger and P. flourescens were evaluated for their antifungal activity against guava wilt fungus (Fusarium oxysporum f. sp.
