Laboratory study to effect some fungicides in growth of Cladosporium fulvum (cooke) that causes leaf mold on tomatoes fungus and spores germinatios

To study the effect of some fungicides invitro on an isolate of the fungus Cladosporium fulvum(cook) that causes leaf mold on tomatoes, five fungicides were tested Flint - Topsin-M- Score and Collisand Indofil-M at concentrations between 1 - 4000 ppm. The results showed that Score and Indofil-M were the most effective fungicides inhibiting hyphal growth for the isolate even at 10ppm. Also, they inhibited completely the spores germinatios at the 100 ppm. The effects of fungicides Flint and Collis were weak on hyphal growth of the isolate and inhibited almost completely the spores germinatios at 1000 ppm. We didn,t observe clear inhibiting effects of Topsin-M on hyphal on the growth of the spores germinatios at 1000 ppm .

Description Of Spores Of Some Syrian Mosses By Using Scanning Electron Microscope

This research is the first descriptive and classifiable study of the Syrian spores of mosses in Syria and Arab world by using the technique of scanning electron microscope. Samples have been collected from several areas from Syria and their names have been defined and classified earlier. The study of nine Spieces of Spores have been completed and their shapes, different faces and the shapes of redundant which they carry and their distribution by scanning electron Microscope are done in Jena University, Germany. Their sizes have been measured and viewed in several sizes. It has been noticed clear differences in Spores, in the Shape of concavity of the frost face and in existence and relation of denseness and distribution of redundant on the faces. So, The characters of Spores can be added to other standards which are used in Classification of mosses.
