The Effects of Solutes, Polymers and Their Mixtures on Mold Conidia Germination
Water activity (Aw) was long held to be the primary predictor of microbial activity in food systems. Recently, it was shown that different components present in food systems also influenced microbial growth and the minimum Aw at which microbial activity occurred. Thus, water activity alone is not a …

Effects of Quorum Quenchers on Aspergillus fumigatus Conidia Aggregation, Adhesion to Surfaces, and Biofilm Formation
… the mentioned antimicrobial agents. A. fumigatus conidia were exposed to the agents and the subsequent changes in the conidial viability, biofilm biomass production, total and EPS-related protein/ polysaccharide/ and nucleic acid were studied. The effect of AMB was weaker than the other agents on …

Environmental-Stress Tolerant Formulations of Metarhizium anisopliae var. acridum for Control of African Desert Locust (Schistocerca gregaria)
… infectivity to Schistocerca americana. Aerial conidia, submerged conidia, and blastospores produced in a high-osmolality liquid medium all had high desiccation tolerance relative to blastospores produced in Adamek's media. Blastospores produced in high osmolality medium were the most infective …

Studies on the physiology of conidial germination by Aspergillus flavus
… to 100%) germination of washed, Tween 20-treated conidia of Aspergillus flavus over a range of conidial densities. No exogenous carbon-independent germination was observed for settling tower-deposited dry conidia. At equivalent carbon, an amino acid mixture supported higher germination of washed …

Immunocytochemical studies of fungal cell surface molecules and the vicia faba-Botrytis interaction
… MAbs bound to fibrillar matrices associated with conidia, germ-tubes and hyphae of B. cinerea and B. fabae grown on agar, glass slides (conidia inoculated in aqueous glucose) and V. faba leaves. These matrices provided firm attachment of sporelings to glass and leaf surfaces. Antibody-binding was …

Mammalian Sporothrix infections in southern Africa : researches on their development, dynamics and control
… moist wood to produce triangular and pigmented conidia, similar to those seen in the gold mine isolates. Pigmented conidia proved to be more viable than unpigmented ones, and pigment production was found to be potentially present in all conidium types. The larger numbers of conidia produced in …

Preliminary evaluation of the rice blast fungus (Magnaporthe grisea) as a potential bioherbicide control agent for crabgrass (Digitaria sanguinalis) infestations of tall fescue (Festuca arundinacea Schreb. cv. Fawn) turf
… concentrations of 5 x 105 to 1 x 106 conidia/mI had no significant difference in effect on mean biomass reduction of treated crabgrass. All produced tissue death and loss of vigor in treated crabgrass, but no plant death. In one trial, a spore concentration of 2 x 106 conidia/ml …

Characterization and Genetic Analysis of The Morphological Mutant <em>Crisp-5</em> of <em>Neurospora crassa</em>
… has a reduced mycelium containing clusters of conidia formed by highly branched conidiophores carried on short aerial hyphae. The mutant <em>cr-5</em> conidiates early and profusely.</p> <p>The time and percent germination of wild type 74A and <em>cr-5</em> conidia were determined. Conidia of …

The analysis of gene transcripts associated with conidiation in the insect pathogenic fungus, Metarhizium anisopliae /
Conidia of the insect pathogenic fungus, Metarhizium anisopliae play an important role in pathogenicity because they are the infective propagules that adhere to the surface of the insect, then germinate and give rise to hyphal penetration of the insect cuticle. Conidia are produced in the final …

Aureobasidium Microstictum (Bubak) Cooke, The Casual Agent of Leaf Streak of Daylily (Hemerocallis L.), and Its Involvement in Spring Sickness of Daylily
… control of Leaf Streak.Regarding to the size of conidia, and shape of fungal structures including, hyphae, conidiophores, and conidia of eight isolates of A. microstictum and one isolate of C. hemerocalli were compared. C. hemerocalligenerally had the same morphological features as A. …

Survival and chemical control of Cylindrocladium spp. inciting root rot of black walnut seedlings
… of microsclerotia. Direct observation of washed conidia of C. scoparium on rewetted, non-sterile soils at 26 C indicated that peak germination (33-58%) occurred after 24 h incubation. Peak germination on continually moist soils was somewhat lower (18-26%) than on rewetted soils. Conidia did not …

Studies on Potential of Resistance Development By Monilinia Fructicola to Selected Fungicides and Isolation of Uv Induced Cga 64251 Resistant Colonies
UV irradiated conidia of Monilinia fructicola were screened for resistance to 5 μg/ml benomyl, 20 μg/ml vinclozolin, 60 μg/ml captan, 4 μg/ml CGA 64251 and 24 μg/ml fenapronil. No isolates resistant to benomyl, vinclozolin, captan or fenapronil were found. From about 1.2 x 10⁶ conidia 137 colonies …
