TLDR
The phylloplane flora of potato leaves was examined from the time of shoot emergence through to leaf senescence and Saprophytic fungi were in general found to be more susceptible to captafol than to maneb plus fentin acetate.Abstract:
The phylloplane flora of potato leaves was examined from the time of shoot emergence through to leaf senescence. Studies on untreated leaves have been combined with others in which the plants were sprayed using one of two fungicides currently in use for late blight control. Saprophytic fungi were in general found to be more susceptible to captafol than to maneb plus fentin acetate. Bacterial numbers were apparently unaltered by the spray treatments.read more

Microbial Ecology of the Mango Phylloplane.
TL;DR: The phylloplane microbial community was qualitatively and quantitatively related to leaf age, position in the tree canopy, seasonality, and chemical spraying, and filamentous fungi and yeasts were more abundant during winter and spring, whereas bacterial population densities increased during autumn.

Prospecting the characteristics and significance of the phyllosphere microbiome
Shobit Thapa,Radha Prasanna +1 more
TL;DR: The present review aims to elucidate the mechanisms of microbial colonization and decipher the nature of spatial and temporal changes in the abundance and diversity in this niche, to illustrate the significance of the different taxonomic groups, and outline future strategies for research on the phyllosphere microbiome.

Effects of late applications of foliar fungicides on activity of micro-organisms on winter wheat flag leaves
C.H. Dickinson,B. Wallace +1 more
TL;DR: There were large increases in yeast populations on aging, green leaves and several filamentous fungi were also common on their surfaces including some which have been previously considered to be important saprophytes on dead leaves.

The growth of rust germ tubes towards stomata in relation to pH gradients
M.C. Edwards,D.J.F. Bowling +1 more
TL;DR: P pH gradients found around closed, but not open, stomata of Commelina communis and Tradescanlia virginiana suggests very strongly that uredospore germ tubes of U. viciae-fabae do indeed use pHGradients as a means of locatingStomata in broad bean rust fungus studies.

The summer air-spora at Rothamsted in 1952.
P. H. Gregory,J. M. Hirst +1 more
TL;DR: The results which should be representative of large rural areas of central and south England show that the major changes of spore concentration depend on the weather and the phenology of the local vegetation and its associated fungal flora.

Fungal colonization of pisum leaves
TL;DR: The increase in saprophyte activity was considered to be primarily a result of alterations in leaf physiology though the possibly beneficial influence of changes in various climatic factors may not be neglected.

Micro-fungi on leaves of Fagus sylvatica
Barbara M. Hogg,H.J. Hudson +1 more
TL;DR: The succession of micro-fungi on leaves of beech has been followed from the time of unfolding up to 18 months after leaf-fall and the fungi which sporulate on the leaves in a well-defined sequence have been divided into three groups.

Effects of captan on the non-parasitic microflora of apple leaves
E.C. Hislop,T.W. Cox +1 more
TL;DR: The microflora of leaves from Worcester Pearmain apple trees sprayed with captan according to normal orchard practice, and from unsprayed trees, was examined by shaking, macerating and spore-fall techniques and no conclusive data were obtained on the toxicity of captan to leaf bacteria.

Air-spora studies at Cardiff. I. Cladosporium.
TL;DR: In this paper, the Cladosporium component of the air spora has been studied over the period 1960-4 using the culture-plate and Hirst spore-trap sampling techniques.
