Abstract:
Powdery mildew (Erysiphaceae) is a detrimental plant disease that occurs on a variety of economically important crops. Powdery mildew consists of over 873 species of fungal pathogens that affect over 10,000 plant species. Genetic identification of powdery mildew is accomplished using the internal transcribed spacer (ITS) and large subunit (LSU) regions of the nuclear ribosomal RNA gene cluster. The ITS and LSU regions of powdery mildews can be useful in ecological, epidemiological, phylogenetic, and taxonomic investigations. However, sequencing these regions is not without its challenges. For example, powdery mildew sequences are often contaminated with plant and/or fungal DNA. Also, there tends to be a limited amount and older specimens’ DNA can fragment over time. The success of sequencing powdery mildew often depends on the primers used for running polymerase chain reaction (PCR). The primers need to be broad enough that they match the majority of powdery mildew DNA yet specific enough that they do not align with other organisms. A review of the taxonomy and phylogeny of the powdery mildews is presented with an emphasis on sequencing the ITS + LSU genomic regions. Additionally, we introduce a new nested primer protocol for sequencing powdery mildew herbarium samples that includes six new powdery mildew-specific primers. The new sequencing protocol presented allows specimens up to 130 years old to be sequenced consistently. Sequencing herbarium specimens can be extremely useful for addressing many ecological, epidemiological, phylogenetic, and taxonomic problems in multiple plant pathogenic systems including the powdery mildews.

Abstract:
This study was conducted to evaluate the susceptibility of grapevine varieties to powdery mildew. Powdery mildew is a disease caused by a fungal, Erysiphenecator, and an obligate parasite of grapevine (Vitisvinifera L.). Powdery mildew causes drastic yield losses of 50 to 70%. Commercial grapevines grown in producing countries are susceptible to powdery mildew. Use of fungicides to control the disease is expensive and not environmentally friendly. Therefore, use of grapevine resistant varieties to powdery mildew is cost-effective control method. In this study, ten varieties (Black rose, Regina, Queen of Vineyards, Alphoncelavallee, Makutupora red, Chancellor, Halilibelyji, Syrah, Ruby seedless and Makutupora white) were screened for resistance to powdery mildew, using artificial inoculation of spore suspension and dry inoculums. Infected grape leaves were sampled from the field and grounded to obtain powder which was used as dry inoculum. The spore suspension inoculum was made by mixing powder with sterilized distilled water. The inoculation was done in two blocks with concentration of 2x105 spore/ml. Disease severity was evaluated based on a scale of 0 5; 0, means immune and 5, high level of disease severity. Results showed significant difference (P<0.05) of disease among grape vine varieties evaluated. It was found that 11.1% were resistant, 33.4% tolerant and 55% susceptible to disease. Grapevine variety Chancellor showed the highest level of resistance, and Black rose the most susceptible. The study demonstrates the effectiveness of using inoculation methods in screening resistance to powdery mildew.

Abstract:
Development of powdery mildew and leaf rust epidemics was examined on three winter wheat cultivars with different predispositions to powdery mildew in three-year experiments. The progress of powdery mildew and leaf rust on the same cultivar was conditioned by its dissimilar susceptibility to the respective disease. Fit temperature played an important role at the beginning of the particular disease and during its progress. Significant differences in the disease severity of powdery mildew and leaf rust were recorded on single leaves. Disease severity of leaf rust was higher on upper leaves while disease severity of powdery mildew was higher on lower leaves.

Abstract:
Abstract Powdery mildew diseases are economically important diseases, caused by obligate biotrophic fungi of the Erysiphales. To understand the complex inheritance of resistance to the powdery mildew disease in the model plant Arabidopsis thaliana, quantitative trait loci analysis was performed using a set of recombinant inbred lines derived from a cross between the resistant accession Kashmir-1 and the susceptible accession Columbia glabrous1. We identified and mapped three independent powdery mildew quantitative disease resistance loci, which act additively to confer disease resistance. The locus with the strongest effect on resistance was mapped to a 500-kbp interval on chromosome III.

Abstract:
Control of downy (Pseudoperonospora cubensis) and powdery [(Podosphoera xanthii (Sphaerotheca fuliginea)] mildew on `Sweet Dumpling' winter squash (Cucurbita maxima) was evaluated at the University of Florida, IFAS, Indian River Research and Education Center (IRREC), in Fort Pierce, Florida during the Spring of 2005. Three foliar spray fungicide treatments were evaluated against an untreated control. Powdery and downy mildew ratings (estimated percentage of foliage damage) and marketable yields (mt/ha) were measured. Plants in the untreated plots had significantly higher powdery and downy mildew ratings. All fungicide treatments significantly reduced both mildews. There were no significant differences among treatments for marketable yield. Although the level of disease occurrence was not sufficient to reduce yields, Gavel alternated with Nova, Bravo Ultrex weekly, and Cabrio + Forum alternated with Bravo Ultrex + Manzate 75WG reduced downy mildew by ≥50%.

Abstract:
Susceptibility to diseases of economically important grapes is critical to the evaluation of germplasm recommended for commercial production and for the development of sustainable production systems. In 2018–2019, the cold-hardy grape cultivars including ‘Brianna’, ‘Crimson Pearl’, ‘Itasca’, ‘Louise Swenson’, ‘Marechal Foch’, ‘Marquette’ ‘Petite Pearl’, ‘St. Pepin’, and ‘Verona’ were evaluated on non-treated vines for susceptibility to downy mildew, powdery mildew, black rot, anthracnose, Phomopsis leaf spot and fruit rot, and Botrytis bunch rot. No cultivars were consistently disease-free, and all exhibited some degree of black rot and powdery mildew infection. Relative susceptibility to disease was not consistent across both years, but ‘Brianna’ had greater incidence of black rot and ‘Louise Swenson’ showed lower incidence of powdery mildew in both years. The relatively new cultivars ‘Crimson Pearl’ and ‘Verona’ exhibited comparatively moderate disease susceptibility overall. Growers typically manage diseases with fungicides on commercial farms, so cultivar susceptibility is just one component of a sustainable pest management and production system.

Abstract:
Abstract Two production nursery fields of flowering dogwood, Cornus florida L., seedlings with a high incidence of powdery mildew were surveyed for plants free of symptoms and signs of the disease. In greenhouse trials most of the seedlings selected in the field survey for being free of powdery mildew were found to be escapes (had no disease resistance) or to exhibit partial resistance (unacceptable low levels of resistance). In those trials, twenty seedlings, representing approximately 0.1% of the seedlings examined in the field surveys, displayed resistance to powdery mildew similar to that of C. florida ‘Cherokee Brave’. This group of disease resistant seedlings will be used to develop new cultivars of white flowering dogwood resistant to powdery mildew and to investigate the inheritance of powdery mildew resistance mechanisms in flowering dogwood.

Abstract:
The virulence of eight isolates of Sphaerotheca humuli (DC.) Burr, was examined on nine varieties of hops (Humulus lupulus L.). Genotypes determined for varieties with race specific resistance generally agreed with previous reports. Although major genes for resistance usually conferred immunity from infection the effectiveness of the gene was shown to be reduced at low temperatures, thereby allowing weak sporulation to develop. The leaf blistering response previously considered to be a consequence of Rg gene determined resistance was shown to be unrelated to the expression of this gene. Quantitative microscopical examination of isolate/variety combinations exhibiting race specific resistance revealed that incompatible fungal sporelings were restricted in the early stages of their development. The expression of the Rg, and R^ resistance genes was associated with a reduction in the frequency with which germinated spores formed haustorial initials. Histochemical and ultrastructural studies showed that the hypersensitive reaction(cell death seen as granulation) in response to epidermal cell penetration was a feature common to most interactions involving major genes for resistance. Adjacent palisade mesophyll cells 'frequently also showed signs of reaction which in severe cases resulted in cellular browning. A 1,3—glucan (probably callose) was deposited in the paramural space and lignin-like compounds appeared to accumulate in the walls and cytoplasmic contents of most reacting mesophyll cells. Callose deposition and lignification were also observed in responding epidermal cells. Infection development on partially resistant breeding lines was studied under laboratory, glasshouse and field conditions. Laboratory experiments revealed that partial resistance to S. humuli was expressed as a reduction in the number of fungal colonies established, an increase in the incubation period and reductions in both the extent and intensity of sporulation. Cellular necrosis was less obvious than in race specific resistance. Comparative studies showed that plants severely infected as seedlings in a glasshouse screen were also severely infected when adult in the hop garden. However, in overall terms there was a relatively poor correlation between the levels of sporulation on seedlings and adult plants of partially resistant breeding lines.

Abstract:
Powdery mildew of cantaloupe, caused by Sphaerotheca fuliginea, is a perennial and often devastating disease in Arizona. During 1987 and 1984 potential new fungicides were evaluated in field trials for disease control. In 1987, Bayleton, Rally and Spotless provided significant disease control. In 1984, Rally and Spotless significantly reduced development of powdery mildew, while Bayleton and Tilt were less effective. Uneven development of powdery mildew within the plot may partially explain the apparent lack of significant disease control in 1988 by Bayleton and Tilt.

Abstract:
Strawberry powdery mildew, caused by Podosphaera aphanis, has the potential to cause over 20% yield loss, particularly where strawberries are grown under cover. A holistic approach to the control of strawberry powdery mildew (P. aphanis) is important, since the disease is never absent from the crop. The new disease assessment key was developed to assess strawberry powdery mildew (the old one is for assessing red blotches on leaves, See appendix 8). The results (Chapter 3) showed that the disease is present in the crop when new plants are bought in from a propagator, with 14% of strawberry crowns were infected by P. aphanis in July 2013 and 4% of the strawberry plants had symptoms of powdery mildew in pre-assessment of plants for the 2013 Si nutrient fertigation field experiment. Control measures used in one growing season reduced the disease carry-over, thus reducing the initial inoculum in the following season. The use of a late autumn fungicide spray and a fungicide spray before the plants were covered by fleece in spring reduced the number and maturity of overwintering chasmothecia, thus contributing to a reduction in initial inoculum. The use of silicon (Si) nutrient (foliar spray and root treatment) also suppressed strawberry powdery mildew development (Chapter 4). The results of Area Under Disease Progress Curve (AUDPC) and the rate of epidemic growth curve (r) in 2012 indicated that the high concentration of Si nutrient foliar spray inhibited (r = 0.002, AUDPC = 44) the epidemic build-up of P. aphanis better than the low concentration of Si nutrient (r = 0.012, AUDPC = 51) and untreated (r = 0.018, AUDPC = 70). The Si nutrient root treatment (AUDPC = 12.8) was better in inhibiting strawberry powdery mildew development than the Si nutrient foliar spray treatment. Moreover, the high concentration of Si nutrient foliar spray resulted in fewer chasmothecia compared to the untreated. Si nutrient foliar spray and root treatments increased the concentration of Si in the plants and produced physiological changes in the plants, including wax formation on the adaxial leaf surface, greater leaf thickness and cuticle layer and increased Brix0 value in plants, which all were associated with reduced disease incidence. The integrated use of all these control strategies suppresses disease development so that control is achieved with less use of conventional fungicides.

Abstract:
Investigations were conducted under greenhouse conditions to evaluate the effects of potassium bicarbonate (PB) on powdery mildew of cucumber caused by E. cichoracearum. PB of two concentrations was applied as foliar sprays to cucumber and K content of the leaf samples was determined by AAC. In the greenhouse, PB provided significant control of powdery mildew with fungal isolates, reducing disease levels by up to 67 %. Higher disease pressure reduced the efficacy of PB on powdery mildew but did not affect the content of the K in leaves. Application of KHCO3 increased the level of K in the leaves, which was responsible for the suppression of the disease.

Abstract:
Here, we present a survey on the evaluation of broad-spectrum fungicides efficacy against cucumber powdery mildew and ascochyta leaf spot. A high efficiency of “Cidely Top 140”, DС (0.1 %) and “Luna Experience”, CS (0.06 %) against powdery mildew was determined. Biological efficacy of these fungicides was 70.9–92.4 % and 73.1–95.3 % after application in the first and second crop rotation, respectively. Plants treatment by “Cidely Top 140”, DС (0.1 %) and “Miravis”, SC (0.05 %) at early stages of ascochyta leaf spot inhibited the disease at the depressive level (2.5–4.8 %) notwithstanding the season of the crop growing.

Abstract:
The fungal agent Microsphaera alphitoides is one of the main agents responsible for degradation of oak ecosystems in Moldova. The development and spread of the oak powdery mildew in the researched areas occurred during two stages of leaves infestation (primary infestation, in spring, through ascospori and secondary infestation, in summer, through conidia), directly depended on meteorological parameters and the presence of the source of infestation. The meteorological conditions in 2018 allowed the spread of the disease in oak stands, especially during the secondary infestation, when leaf infestation with the fungus mycelium was at medium level (inside the experimental surfaces) and reached a medium to strong level of infestation on trees at the forest edge. The high susceptibility of oak trees to this disease requires development of strategies to reduce the risk of "powdery mildew".
