The pesticides used to control pests and diseases are also implicated in ecological, environmental and human health hazards. To reduce the deleterious effects of these agrochemicals, certain antagonistic microorganisms have been characterised from rhizosphere of different crop plants that suppress various plant diseases and thus, minimise the use of pesticides. The application of these specific...

Certain strains of root-colonizing fluorescent Pseudomonas spp. produce phenazines, a class of antifungal metabolites that can provide protection against various soilborne root pathogens. Despite the fact that the phenazine biosynthetic locus is highly conserved among fluorescent Pseudomonas spp., individual strains differ in the range of phenazine compounds they produce. This study focuses on ...

Soilborne plant diseases are a major constraint to crop production worldwide. Effective and economical management of these is dependent on the ability accurately detect diagnose their signs and/or symptoms prior widespread development in crop. Sensor-based technologies promising tools for automated disease detection, but research still needed optimize validate methods detection specific disease...

In many Arkansas cotton fields, factors such as inefficient tillage operations, extremely dry weather and traffic pressure may result in a compacted soil layer or hardpan. Soil compaction dramatically increases soil strength and can restrict cotton root penetration, leading to suppressed cotton height and lint yield (Taylor and Earl Burnett, 1963). This problem may be exacerbated by soilborne p...

Abstract Pesticides are the necessary agrochemicals used in agricultural practice for prevention of crops from pests and diseases. may have direct effects on non-target organisms, particularly these saprobic symbiotic soilborne fungi. Dark septate endophytes (DSE) endophytic fungi that colonize living plant roots without causing a negative impact. DSE might function as mutualistic taking part n...

Various cultural practices, including the use of cover and rotational crops, composts, tillage systems, and others have been promoted as management options for enhancing soil quality and health. All cultural practices are known to directly or indirectly affect populations of soilborne pathogens and the severity of their resultant root diseases. Soil biology is a major component and contributes ...

Bacillus amyloliquefaciens SQR9 exhibited predominantly antagonistic activities against a broad range of soilborne pathogens. The fungi-induced SQR9 extracts possess stronger antifungal activities compared with SQR9 monoculture extracts. To investigate how SQR9 fine-tunes lipopeptides (LPs) and a siderophore bacillibactin production to control different fungal pathogens, LPs and bacillibactin p...
