The major diseases affecting chilli productions are Anthracnose, Phytopthora, Leaf blight, Fusarium wilt, bacterial wilt, damping-off and root rot etc. Among these, Fusarium wilt caused by the Fusarium oxysporum has emerged as a serious problem in recent year. In this investigation, to study the mycorrhizal population dynamics and wilt intensity in chilli growing areas of state, the survey was undertaken during crop season 2017-18 in Hisar, Fatehabad and Mohindergarh districts. Two to three field from each village and total ten fields were observed from each district. The mycorrhizal per cent colonization in roots and number of sporocarp in soil was maximum in Mahendragarh (13.4 per cent mycorrhizal colonization and 83 sporocarps/ 100g soil) followed by Fatehabad district (7.5 per cent mycorrhizal colonization and 63.3 sporocarps/ 100g soil) and minimum in Hisar district (4.7 per cent mycorrhizal colonization and 39.4 sporocarps/ 100g soil). The maximum wilt intensity was recorded from the Fatehabad district (7.9 per cent), followed by Mahendragarh (7.3 per cent) and minimum from Hisar (5.2 per cent). Glomus spp. was prevalent in all the districts surveyed.
