dc.description.abstractGuava (Psidium guavajava L.) is an important fruit crop of subtropical countries, which is grown in almost all the states of India. It‟s cultivation is affected by many diseases, among which wilt complex disease caused by Fusarium species and Meloidogyne enterolobii is the most destructive disease. In the survey conducted during 2019, among five districts, the average per cent wilt incidence was recorded maximum in Bagalkote district (16.5%) followed by Kolar (10.7%), Koppal (10.33) and Dharwad (6.46%) whereas minimum wilt incidence was observed in Ramanagara (1.16%). The average root and soil nematode population was recorded maximum in Bagalkote (336 and 195.75) whereas, minimum root and soil nematode population was recorded in Ramanagara (24.75 and 14.75). The Fusarium species was isolated, purified and characterized based on cultural characters. The prevailing root knot nematode species was characterized based on the perineal pattern. Interaction between fungi and nematode on guava seedlings were studied under pot condition, which revealed that inoculation of Meloidogyne enterolobii two weeks prior to inoculation of Fusarium species showed early wilting symptoms and adversely affected the plant growth parameters. In vitro studies recorded that tebuconazole 250EC at 0.025%, COC 50%WP at 0.1% and (Mancozeb63%+Carbendazim75%) WP at 0.3% were found effective and among the bio agents Trichoderma harzianum and T. asperellum were found effective against Fusarium species. Under field condition, the combined application of Trichoderma harzianum (100g/plant) + Neem cake (250g/plant) + Nimitz (40g/plant) + Mancozeb 63%+ Carbendazim 12% (0.2%) + Paecilomyces lilacinus (25g/plant) were found effective in managing the wilt complex disease of guava, which recorded the least per cent wilt incidence of 4.33 with high fruit yield (15 kg) and B:C ratio (2.16).
