abstract pythium aphanidermatum is one of the most important agent of root and foot rot of cucumber, particularly in the warm humid climate. induction of host resistance by microorganisms or by the synthetic compounds is recently considered as one of the biological control method of disease. trichoderma harzianum bi is a good candidate for induction of resistance in plant against diseases. the ...

Rhizoctonia solani causes economically important root and hypocotyl diseases in common bean throughout the world. Root health is a vital factor in plant development and root diseases would negatively influence water and nutrient uptake as well as cause direct stand reduction and root rot damage to the crop. An efficient common bean screening method to evaluate damping-off and early root/ hypoco...

Subterranean clover (Trifolium subterraneum) is a critical pasture legume in Mediterranean regions of southern Australia and elsewhere, including Mediterranean-type climatic regions in Africa, Asia, Australia, Europe, North America, and South America. Pythium damping-off and root disease caused by Pythium irregulare is a significant threat to subterranean clover in Australia and a study was con...

Alfalfa Fusarium Root Rot (AFRR) is a serious soil-borne disease with complex pathogenicity. Diseased samples suspected of AFRR were collected from Hohhot, Ordos, Hulunbeier, Chifeng, and Bayannur in Inner Mongolia, China, leading to 317 isolates. The isolates identified as acuminatum, F. solani, equiseti, incarnatum, oxysporum, avenaceum, verticillioides, proliferatum, falciforme, tricinctum, ...

Citrus is one of the most important fruit crops cultivated in South Africa. Internationally, citrus dry root rot a common disease major production areas. Several abiotic and biotic factors are involved development, which Neocosmospora species agents. The diversity associated with symptoms trees Africa was evaluated using morphological molecular analyses. Multi-locus analysis conducted, based on...

The most destructive root rot pathogen of Norway spruce (Picea abies) in Finland is Heterobasidion parviporum. After primary infection, this spreads from tree to through contacts and eventually causes high levels stem rot. Locus PaLAR3 has been associated with resistance spruce, higher against H. parviporum noted when trees have allele PaLAR3B instead the more common PaLAR3A. In study we tested...
