The soilborne fungus Verticillium dahliae is the major pathogen that causes the verticillium wilt disease of plants, which leads to huge economic loss worldwide. At the early stage of infection, growth of the pathogen is subject to the nutrition stress of limited nitrogen. To investigate the secreted pathogenic proteins that play indispensable roles during invasion at this stage, we compared th...

Biological control of soilborne plant pathogens using beneficial fungi, such as the mycoparasite Trichoderma harzianum, offers the prospect of environmentally benign pest control. However, biocontrol organisms have their own natural enemies; for example the fungivorous nematode Aphelenchoides saprophilus preys on T. harzianum. A trophic cascade occurs when three or more trophic levels are prese...

Ceratocystis wilt on eucalyptus, caused by Ceratocystis fimbriata, was first recognized in 1997 in the state of Bahia, Brazil, but is now known in five other states and in four other countries. C. fimbriata is a native, soilborne pathogen in some parts of Brazil but we hypothesized that genotypes of the pathogen have been moved among plantations in rooted cuttings collected from diseased trees ...

Sci., 19: 530-535 Methyl jasmonate (MeJA), which is one of the plant lipid derivatives, is considered as a signaling substance during plantmicrobe interactions. It is related to plant resistance to biotic and abiotic stress. To assess the i...

Macrophomina phaseolina (Tassi) Goid. is a soil- and seed-borne pathogen that causes charcoal rot various rots blights of more than 500 crop species. Dry root (DRR) also called as which yield loss ranged from 25-48 per cent. The necrotroph infects wide range crops. It observed mycelium M. in cotyledons, plumule radicle, the naturally infected seeds mungbean cowpea. disease symptoms are clearly ...

During the summer of 2016, severe dieback was observed on young potted Prunus lusitanica (Portugal laurel) plants in a nursery Pistoia province (Tuscany, Italy). Cylindrocarpon-like isolates were consistently recovered from diseased plant tissues. The combination morphological and molecular traits, including sequence data histone 3 β-tubulin genes (HIS3, TUB2) internal transcribed spacers (ITS)...

Anaerobic soil disinfestation (ASD) is a promising alternative to chemical fumigation for controlling soilborne plant pathogens and weeds. This study investigated the impact of brewer’s spent grain (BSG), locally available carbon source, on various weed species oomycete pathogen Pythium irregulare in ASD. Two greenhouse studies were conducted using BSG yeast at full reduced rates completely ran...
