The discoloration problem of rubber wood caused by the fungi has degradation and greatly reduced its economic value, prevention control have become top priority basic research on protection modification. To determine fungal community diversity dominant groups before after wood, nine samples were subjected to ITS sequencing using Illumina high-throughput technology. results showed that detected ...

11 fungi sampled from Quercus acorns with symptoms of black rot and mummification and from necrotic twigs of Q. petraea were tested for pathogenicity towards seedlings of Q. petraea, Q. robur and Q. rubra in a field experiment. Six months after inoculation, necrosis on the main stem and the subsequent death of Q. robur and Q. petraea plants were observed after inoculation with Aureobasidium pul...

Many compounds produced by fungi have relevant pharmaceutical applications. The purpose of this study was to collect and isolate endophytic fungi from different regions of Panama and then to test their potential therapeutic activities against Leishmania donovani, Plasmodium falciparum, and Trypanosoma cruzi as well as their anticancer activities in MCF-7 cells. Of the 25 fungal isolates obtaine...

The health condition of the population of elms in the region of southern Bohemia was studied from the viewpoint of their decline, the occurrence of Dutch Elm Disease (DED) and the presence of other diseases. Of the total number of 105 elms in total 33 of them were without any symptoms of the disease or other damage. Elms regenerated quite spontaneously in the neighbourhood of mother trees and t...

The generic concept of Phyllosticta has undergone substantial changes since its establishment in 1818. The existence of conidia with a mucilaginous sheath and an apical appendage is synapomorphic for Phyllosticta species, which has been shown in recent molecular phylogenetic studies. Thus a natural classification of Phyllosticta species should emphasize above morphological characters. Many name...

A groups of novel water soluble chitosan derivatives containing 1,3,4-thiadiazole group were synthesized including 1,3,4-thiadiazole (TPCTS), 2-methyl-1,3,4-thiadiazole (MTPCTS), and 2-phenyl-1,3,4-thiadiazole (PTPCTS). Their antifungal activity against three kinds of phytopathogens was estimated by hypha measurement in vitro, and the fungicidal assessment shows that the synthesized chitosan de...

Four new chromone derivatives, phomopsichins A-D (1-4), along with a known compound, phomoxanthone A (5), were isolated from the fermentation products of mangrove endophytic fungus Phomopsis sp. 33#. Their structures were elucidated based on comprehensive spectroscopic analysis coupled with single-crystal X-ray diffraction or theoretical calculations of electronic circular dichroism (ECD). They...

MilStop fungicide was recently registered for the control of a number of leaf spot and blight diseases, as well as powdery mildew on numerous annual, herbaceous, and woody ornamentals. The active ingredient in MilStop is potassium bicarbonate. MilStop is reported to have curative activity against powdery mildew and is also labeled for the control of diseases caused by fungi such as Alternaria ,...
