Soil disinfestation with steam has potential to partially replace fumigants such as methyl bromide, chloropicrin, and 1,3-dichloropropene because it is effective, safer apply, less negative impact on the environment. Here, we compared efficacy of + mustard seed meal (MSM) chloropicrin soil disinfection, plant growth, fruit yield in a strawberry ( Fragaria × ananassa ) fruiting field. The MSM wa...

Abstract Background Apple decline diseases, responsible for seedlings root and collar rot in nurseries, are an important disease. Different fungal bacterial antagonists were evaluated to control Pythium ultimum associated with this serious disease using vitro vivo greenhouse assays. Results The test of ten Aspergillus spp. Trichoderma harzianum isolates showed their efficacy reduce the radial g...

In the biocontrol strain Pseudomonas fluorescens CHA0, the Gac/Rsm signal transduction pathway positively controls the synthesis of antifungal secondary metabolites and exoenzymes. In this way, the GacS/GacA two-component system determines the expression of three small regulatory RNAs (RsmX, RsmY, and RsmZ) in a process activated by the strain's own signal molecules, which are not related to N-...

Numerous studies have demonstrated the potential of composted organic wastes not only as substitutes for peat as a growth substrate but also to stimulate plant growth and suppress soil-borne diseases. The major impediment to the use of compost as substrates or biocontrol agents has been variation in physical and chemical characteristics and disease suppression levels across and within compost t...

Pseudomonas koreensis, a new nominated Gram-negative bacterium was first reported and isolated from Korean agricultural soil (Kwon et al., 2003). CRS05-R5 (first reported as Pseudomonas sp.), which showed biocontrol ability against Sitophilus oryzae andAcidovorax avenae subsp. avenae (Liu et al., 2014), was first isolated from the rice rhizosphere in Heilongjiang province and reported in 2003 (...

Trichoderma virens (synonym, Gliocladium virens), a deuteromycete fungus, suppresses soilborne plant diseases caused by a number of fungi and is used as a biocontrol agent. Several traits that may contribute to the antagonistic interactions of T. virens with disease-causing fungi involve the production of peptide metabolites (e.g., the antibiotic gliotoxin and siderophores used for iron acquisi...
