Effects of culture media and environmental factors on conidial germination, pycnidial production and hyphal extension of Coniothyrium minitans

Dynamics (seasonal and intra-diurnal) of air-borne fungal spore population of Doha area, Qatar

“…Both, Potatodextrose agar (PDA) and malt extract agar (MEA) produced the highest rate of conidial germination, pycnidial production and hyphal extension of Coniothyrium minitans. Hyphal extension rate on molasses-yeast agar was more dawdling, other developmental processes rate were similar to those on PDA and MEA (Mcquilken et al, 1997). A single stage / N6…”

“…Penicillium and Ulocladium were highly selective, while Penicillium showed high growth pattern on glucose, Ulocladium were recovered mainly on cellulose (Abdel-Hafez , 1984).According to Moubasher, (1993) 50% sucrose Czapek's agar provides the highest total count of fungal recoveries and the widest species spectrum in comparison with glucose and cellulose-Czapek's agar. Mcquilken et al, (1997) proved that not only temperature, pH and light affect the development on fungal growth, but also the laboratory substrata can drive the developmental process. Both, Potatodextrose agar (PDA) and malt extract agar (MEA) produced the highest rate of conidial germination, pycnidial production and hyphal extension of Coniothyrium minitans.…”

Molecular studies on intraspecific diversity and phylogenetic position of Coniothyrium minitans

“…It has been shown to control Sclerotinia sclerotiorum, a widespread soil-borne plant pathogen, in both field and glasshouse trials (Huang 1980, Whipps & Budge 1990, Budge & Whipps 1991, Budge et al 1995, Evenhuis et al 1995, McQuilken, Budge & Whipps 1997a, Gerlagh et al 1999 and currently there are two commercial products, Contans2 and KONI (Whipps & Davies 2000). There has been considerable recent interest in inoculum production, formulation and application (McQuilken, Budge & Whipps 1997b, c, Weber, Tramper & Rinzema 1999, 2000, ecology (Williams, Whipps & Cooke 1998a, b, Jones et al 1999 and physiology (Smith et al 1998, 1999, Ooijkaas et al 1999 of C. minitans.…”

A novel method to optimize culture conditions for biomass and sporulation of the entomopathogenic fungus Beauveria Bassiana IBC1201

“…Hyphal extension and pycnidial production of four isolates of Coniothyrium minitans, a fungus that parasitizes plant-pathogenic fungi, occurred over a pH range of 3-8, with optimum values between pH 4.5 and 5.6 (37). A pH range between 3 and 6 allowed active mycelia extension of the plant-pathogenic fungus Potebniamyces pyri (47).…”

“…The mycelial growth of the plant-pathogenic fungus Sphaeropsis pyriputrescens was enhanced by fluorescent light (26), and light greatly affected pycnidia formation by some Sphaeropsidales species (1,28), including Ascochyta pisi (29) and Botryodiplodia theobromae (8). Light significantly increased the pycnidial production but not the growth of four isolates of C. minitans (37).…”
