Onset and more severity were recorded in villages situated on Krishna River Bank and are considered as hot spots of disease. Deposition of uredospores on slide kept in aeroscope commenced 6 to 9 days before onset of disease. Fluctuations in uredospore deposition were observed. More uredospores were trapped between 75 to 90 DAS and rust severity was maximum at this stage. Autoregression model of seventh order was found to be accurate for prediction of uredospores load in atmosphere. Logistic model and linear environmental model were appropriate for predicting rust epidemics. Uredospores survived for 12 to 15 days in infected host debris. Disease prevailed on soybean throughout the year with difference in severity. Cowpea, pea, greengram, horsegram, redgram and frenchbean were found to be collateral hosts. Onset of rust was delayed on early sown crop and severity increased with delayed sowing in kharif. Drastic reduction in yield and seed weight was recorded with delayed sowing. Among the varieties PK-1029 recorded the least severity with all the sowing periods. Among germplasms S-22, WC-12 and 92-10 performed better in yield with resistant reaction. Among varieties PK-1162, PK-1029, JS-80-21 and PK-1024 showed moderately resistant reaction with good yield. Three and two sprays of hexaconazole (0.1%) were required to manage rust on a susceptible {JS-335) and a moderately resistant (PK- 1029) varieties respectively. Yield loss of 81.94 and 65.73 per cent due to rust was observed with JS-335 and PK-1029 respectively. Yield loss model could be developed by using AUDPC as input variable. Severity at 75 and 85 DAS was highly significant and positively correlated with yield loss in JS-335 and PK-1029 respectively."ThesisItem Open Access ETIOLOGY AND MANAGEMENT OF FOOT ROT OF BLACK PEPPER (Piper nigrum L.)(University of Agricultural Sciences, Dharwad, 1998) JAHAGIRDAR, SHAMARAO; SIDDARAMAIAH, A LABSTRACT NOT AVAILABLEThesisItem Open Access STUDIES ON THE INFLUENCE OF CERTAIN EXOGENOUSLY APPLIED SUBSTANCES ON PEPPER VEIN BANDING VIRUS TRANSMISSION, MULTIPLICATION AND SYMPTOMS IN BELL PEPPER (CAPSICUM ANNUUM L.)(University of Agricultural Science, Dharwad, 1996) NACARAJU, N; REDDY, H RABSTRACT NOT AVAILABLEThesisItem Open Access EPIDEMIOLOGY AND CONTROL OF ANTHRACNOSE DISEASES OF COFFEE INCITED BY Colletotrichum gloeosporioides (PENZ.)
