Two stable mutants, one each of Trichoderma viride (TvM1) and Trichoderma harzianum (ThM1), obtained through gamma radiation were tested for their compatibility with different pesticides in order to fit them in integrated disease management for the control of fusarial wilt of chilli. Both the fungal mutants showed high compatibility carbendazim (0.1%), fipronil (0.2%), imidacloprid (0.025%) and fluchloralin (0.33%). TvM4 showed compatibility with captan (0.25%), copper oxy chloride (0.15%), phosalone (0.1%) and butachlor (0.2%) and ThM1, was compatible with mancozeb (0.125%) and phosalone (0.1%). Mancozeb (0.25%), copper oxy chloride (0.3%), dicofol (0.5%), pendimethalin (0.66%) and alachlor (0.4%) were found to be highly inhibitory to the radial growth of the mutants TvM1 and ThM1.Keywords

The present study mainly focused on the diversity of spider fauna in the agro-ecosystem of Mahabubnagar district during the Kharif and Rabi seasons of 2020-21. The sampling was collected at monthly intervals by different methods (in situ counts, net sweeping, pitfall traps and litter sampling). A total of 30 spider species were identified of which, Araneidae family is represented by 8 species belonging to four genera followed by the Salticidae family (5 species), Oxyopidae (4 species), Lycosidae and Pholcidae (3 species), Thomisidae (2 species) Gnaphosidae, Hersillidae, Sparassidae and Tetragnathidae represented by one species, respectively. The diversity indices viz., Shannon-Weiner Index (2.785- Kharif season and 2.752-Rabi season), Simpson Index (0.912-Kharif season and 0.899 Rabi season), Margalef Index (4.122- Kharif season and 4.25- Rabi season) and Pielou’s Index (0.104 Kharif season and 0.09 Rabi season) were calculated.Keywords
