Evaluation of Biostimulants to Control Guignardia Leaf Blotch (Guignardia aesculi) of Horsechestnut and Black Spot (Diplocarpon rosae) of Roses
Biostimulants are classified as materials that are neither a fertilizer nor a pesticide, but when applied to a plant will enhance their health, growth, and protection. Manufacturers claim biostimulants have underexploited potential in providing protectant properties to plants against pathogen attack. This study evaluated the efficacy of seven commercially available biostimulants against the fol...
متن کاملA draft genome sequence of the rose black spot fungus Diplocarpon rosae reveals a high degree of genome duplication
BACKGROUND Black spot is one of the most severe and damaging diseases of garden roses. We present the draft genome sequence of its causative agent Diplocarpon rosae as a working tool to generate molecular markers and to analyze functional and structural characteristics of this fungus. RESULTS The isolate DortE4 was sequenced with 191x coverage of different read types which were assembled into...
متن کاملMining Disease-Resistance Genes in Roses: Functional and Molecular Characterization of the Rdr1 Locus
The interaction of roses with the leaf spot pathogen Diplocarpon rosae (the cause of black spot on roses) is an interesting pathosystem because it involves a long-lived woody perennial, with life history traits very different from most model plants, and a hemibiotrophic pathogen with moderate levels of gene flow. Here we present data on the molecular structure of the first monogenic dominant re...
متن کاملSpecific Mapping of Disease Resistance Genes in Tetraploid Cut Roses
Control of fungal diseases is a major constraint of cut-rose cultivation in greenhouses and in transportation around the world. Therefore, development of resistant cultivars is a promising way to reduce the use of chemicals required for controlling the diseases. Genetic analyses and breeding for resistance, however, are hampered by the high degree of heterozygosity and the polyploid nature of c...
متن کاملeffects of fertilizer treatments on components, performance components and induce resistance to wheat scab disease
fusarium head blight (fhb) disease caused by fusarium graminearum is one of the most destructive diseases of wheat that in addition to the loss of product quality and quantity is able to produce the dangerous carcinogenic toxins in human and animals. in this study, the effects of different fertilizer treatments (vermicompost, chemical fertilizer and mycorrhiza) on performance components and exp...
