Nutritional and physiological studies of Fusarium oxysporum f. sp. ciceri (Padwick) Snyder and Hansen causing wilt of chickpea

Abstract

Nutritional and physiological requirements of Fusarium oxysporum f. sp. ciceri were studied using most virulent isolate FOC-2 (Jalna). Effect of different culture media on mycelial growth of Fusarium oxysporum f. sp. ciceri showed significant differences in growth and sporulation. In vitro, culture media studied, Potato dextrose agar (89.66 mm) and Richard agar medium (85.66) produced significantly highest mean mycelial growth and sporulation. The temperature in the range of 25 0 C to 30 0 C and pH having range of 6.0 to 7.0 produce significantly highest mean mycelial growth and sporulation of the test pathogen.

Variability of Fusarium verticillioides Isolates causing Maize Post Flowering Stalk Rot with Respect to Growth Parameters on Culture Media

“…The results obtained are in confirmation to the findings of Rana et al, (2017) where F. oxysporum f. sp. cubense attained very good sporulation in Potato dextrose broth and also the results are in tune with the Thaware et al, (2016) where they found F. oxysporum f. sp. ciceri showed excellent sporulation in Potato dextrose broth.…”

Morphological aspects and effect of carbon sources in the physiology of Fusarium oxysporum f. sp. passiflorae

“…ciceri on chickpea (Thaware et al, 2016;Nath et al, 2017;Farooq et al, 2005;Khilare and Ahmed, 2011), F. oxysporum f. sp. lentis on lentil (Altaf et al, 2014), F. oxysporum f. sp.…”

“…Exhibits high degree of variability in the morphological and physiological characteristics, being considered the most widely disseminated Fusarium species that can be recovered from most soils (Leslie and Summerell, 2006), varying significantly with the environmental conditions (Kumara and Rawal, 2008) and occupying diverse ecological niches and geographic regions (Islam, 2015). Thus, different substrates can allow their growth (Godswill et al, 2015;Chougule and Andoji, 2016;Shinde and Hallale, 2016;Thaware et al, 2016;Nath et al, 2017), among them, Potatro-Dextrose-Agar, Agar Sabouraud, Carnation-Agar, Spezieller Nährstoffarmer Agar (Tapia and Amaro, 2014), glucose (dextrose), D-fructose, D-manose, D-galactose, starch, D-xylose, D-sorbose, D-mannitol, sucrose, D-lactose, D-maltose, citric acid, succinic acid, tartaric acid, D-raffinose, tannic acid, melibiose and dextrin (Shilpa et al, 2015).…”

“…Fusarium species may be differentiated based on the size and shape of macroconidia, presence and absence of microconidia and chlamydospores, colony morphology (Albores et al, 2014), mycelial growth and sporulation on different substrates (Godswill et al, 2015;Shilpa et al, 2015;Chougule and Andoji, 2016;Shinde and Hallale, 2016;Thaware et al, 2016;Nath et al, 2017).…”

Biological Management of Fusarium Wilt in Chickpea (Cicer Arietinum L.) Caused by Fusarium oxysporum f. sp. ciceris

“…It belongs to leguminosae family with widely cultivated around 50 countries about 90 per cent of cultivated area occupied by Asia, Africa, Central and South America (Jimenez-Diaz et al, 2015). India, accounts for 75% of world's chickpea production on 13.98 million ha area with production 137.3 lakh tonnes and productivity 982 kg/ha (Thaware, et al, 2016). In Tamil Nadu, chickpea was cultivated in an area of 6820 hectares with a production of 4177 tonnes and a productivity of 645 Kg / ha.…”
