Phytophthora diseases have become a major impediment in the citrus production in Thailand. In this study, an isolate of Phytophthora denominated as PHY02 was proven to be causal pathogen of root rot of Pomelo (Citrus maxima) in Thailand. The isolate PHY02 was morphologically characterized and identified as Phytophthora palmivora based on molecular analysis of an internal transcribed spacer rDNA...
Abstract Phytophthora medicaginis causing root rot of chickpea ( Cicer arietinum ) is an important disease, with genetic resistance using C . × echinospermum crosses as the main disease management strategy. We evaluated pathogenic variation in P populations aim improving phenotyping methods for resistance. addressed question individual isolate aggressiveness across four different seedling‐based...
The root rots of wheat, oats, barley, and rye are among the least conspicuous diseases of cereals, but they are among the most destructive. They are caused by many species of fungi, which are widespread and live on or in seed, soil, and dead plant refuse. They attack a large number of hosts and thrive under a wide range of conditions.

Filamentous disease-causing agents (e.g., fungi and oomycetes) constitute a diverse, widely distributed group of plant pathogens that continually threaten crop production. A prominent example is Phytophthora sojae, pathogenic oomycete renders root stem rot in soybean (Glycine max). The expansion diverse/complex P. sojae pathotypes limits traditional methods disease prevention exacerbated by cli...
Abstract Microbial plant growth promoters (MPGP) are known to improve crop nutrition and root health. Here we examined the effects of individual combined inoculation chili pepper (variety Camino Real) with Rhizophagus irregularis (isolate BEG87) a commercial product Azospirillum brasilense on biocontrol against oomycete pathogen Phytophthora capsici CH11). In greenhouse pot experiment, unfertil...
