Biochar (BC) is increasingly applied in agriculture; however, due to its adsorption and degradation properties, biochar may also affect the efficacy of fumigant in amended soil. Our research is intended to study the effects of two types of biochars (BC-1 and BC-2) on the efficacy and emission of methyl isothiocyanate (MITC) in biochar amendment soil. Both types of biochars can significantly red...

ABSTRACT The choice of detection method for phytopathogens can be critically important in determining the success or failure of pest regulation systems. We present an assay for Phytophthora ramorum that uses 5' fluorogenic exonuclease (TaqMan) chemistry to detect and quantify the pathogen from diseased tissue, and include a universal primer and probe set for an internal positive control. This m...

Plant inoculation with endophytic bacteria that normally live inside the plant without harming the host is a highly promising approach for biological disease control. The mechanism of resistance induction by beneficial bacteria is poorly understood, because pathways are only partly known and systemic responses are typically not seen. The innate endophytic community structures change in response...

Previously, Colletotrichum spp. has been considered a warmer climate pathogen as these meteorological conditions are most optimal for its development. However, change is fostering the spread of plant disease and complicating ability to predict This study aims determine anthracnose development, evaluate susceptibility different strawberry cultivars detect distribution pathogens in temperate cond...

ABSTRACT A microbioassay was developed for the discovery of compounds that inhibit Phytophthora spp. This assay uses a 96-well format for high-throughput capability and a standardized method for quantitation of initial zoospore concentrations for maximum reproducibility. Zoospore suspensions were quantifiable between 0.7 and 1.5 x 10(5) zoospores per ml using percent transmittance (620 nm). Sub...
