The imminent removal of agrochemicals in Europe is directly affecting the strawberry sector Spain, specifically Huelva province. currently main producer country. lack efficient fumigants has led to rise soilborne diseases. Macrophomina phaseolina (the causal agent charcoal rot strawberries) generating serious problems with farmers. This work proposes optimize process anaerobic soil disinfestati...

Common root rot (CRR) caused by the soilborne pathogen Bipolaris sorokiniana (teleomorph Cochliobolus sativus) is becoming increasingly prevalent worldwide. Identification of CRR difficult and time-consuming for human assessors due to non-distinctive above-ground symptoms, with browning subcrown internodes roots most distinguishing symptom infection. disease has been recognized as a significant...

Context Rotations in rainfed farming systems of southwest Australia have shifted towards intensified cropping and it is necessary to reassess soilborne pathogens plant parasitic nematodes within this context. Aims We tested the hypothesis that these recent changes rotations agronomy altered efficacy with which reduce incidence common root nematodes. Methods tracked pathogen DNA soil severity cr...

Mbofung, G. C. Y., Fessehaie, A., Bhattacharyya, M. K., and Leandro, L. F. S. 2011. A new TaqMan real-time polymerase chain reaction assay for quantification of Fusarium virguliforme in soil. Plant Dis. 95:1420-1426. The quantification of the soilborne pathogen Fusarium virguliforme inoculum in soil is important for epidemiological studies of soybean sudden death syndrome (SDS). Classical dilut...

Phytophthora capsici is a soilborne oomycete plant pathogen that causes severe vegetable crop losses in New York (NY) state and worldwide. This difficult to manage, part due its production of long-lasting sexual spores tendency quickly evolve fungicide resistance. We single nucleotide polymorphism (SNP) genotyped 252 P. isolates, predominantly from NY, order conduct genome-wide association stud...

Stand problems consistently cause significant production losses and management problems in Arkansas rice fields. Previous research, funded by the Rice Research and Promotion Board, identified the role of environmental factors and soilborne plant pathogens in limiting rice stand establishment, and had the goal of determining the conditions where soilborne pathogens, especially Pythium species, p...

Soilborne fungal pathogens cause devastating yield losses and are highly persistent and difficult to control. During the infection process, these organisms must cope with limited availability of iron. Here we show that the bZIP protein HapX functions as a key regulator of iron homeostasis and virulence in the vascular wilt fungus Fusarium oxysporum. Deletion of hapX does not affect iron uptake ...

The efficacy of fallow and coastal bermudagrass (Cynodon dactylon) as a rotation crop for control of root-knot nematode (Meloidogyne incognita race 1) and soilborne fungi in okra (Hibiscus esculentus cv. Emerald), squash (Cucurbita pepo cv. Dixie Hybrid), and sweet corn (Zea mays cv. Merit) was evaluated in a 3-year field trial. Numbers of M. incognita in the soil and root-gall indices were gre...
