Charcoal rot is an important disease for sunflower plants, a crucial oil crop in Egypt and globally. Field experiments were conducted in Ismailia Governorate, Egypt during the 2020 and 2021 growing seasons in soil naturally infested with Macrophomina phaseolina to study the effect of water source and irrigation systems on charcoal rot development on sunflower plants. River Nil (non-sodic containing 0.84 meq sodium/ L), deep-well (sodic containing 59 meq sodium/L), and surface and drip irrigation were used. The incidence of charcoal rot was increased under well water and drip irrigation more than river water or surface irrigation. Infection increased from 27.5 to 27.3% with river water via surface irrigation to 37.4 and 38.2% with well water via drip irrigation in the first and second seasons respectively. Nitrogen concentration in sunflower leaves was not influenced by water source or irrigation system, while P and K decreased from15.1, 15.4, 24.3 and 24 mg/ gm with river water to13.1, 13.5, 13.3 and 14.3 mg/ gm with well water when surface irrigation used in the first and second season. Seed yield and oil concentration decreased from 43.1 to 44.7 kg seed/ plot; and 57.4 and 47.5% seed oil with river water to 37.4 and 35.8 kg seed/ plot; and 43.6 and 38.2% seed oil with well water via surface irrigation in first and second season.Well water increased sodium accumulation in the soil compared to river water from 1.49 to 1.74 kg/ hectare. Irrigation system did not affect sodium content when river water used, while with well water, drip irrigation increased sodium content more than surface irrigation. Consequently, water quality and irrigation systems affect sunflower plants’ growth, charcoal rot incidence, and may increase sodium accumulation in soil.</div>","PeriodicalId":8598,"journal":{"name":"Australasian Plant Pathology","volume":"54 1","pages":"73 - 80"},"PeriodicalIF":0.9,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the increase in cucumber cultivation areas in recent years, soil-borne plant disease such as Pythium spp. and Fusarium wilt (FW) have caused significant economic losses for producers. Filamentous Trichoderma fungi and gamma radiation are well known for their ability to stimulate many plant-pathogen fungal interactions, plant defense mechanisms against these fungi (antagonistic, competitive, etc.), and plant growth. This study aims to examine the effects of Trichoderma spp. (Trichoderma harzianum and Trichoderma virens), which are among the sustainable practices against F. oxysporum f. sp. cucumerinum and P. aphanidermatum pathogens, and the effects of gamma rays (0, 50, 100, 150, 200, and 250 Gy), which are used as a reliable method for changing physiological and biochemical processes in plants and investigating their interactions with pathogens. The results revealed that the interaction between gamma rays and Trichoderma species increased the fresh and dry weights and shoot and root length values of the cucumber plants and decreased the disease severity. When Trichoderma harzianum (%51-%78 impact) and Trichoderma virens (%40-%67 impact) were compared, their effects on plant growth and disease severity were determined to vary according to parameters and gamma doses. These results indicate that gamma mutations may improve the biocontrol properties of T. harzianum and T. virens. According to the results of this study, gamma rays can be used in sustainable agricultural practices together with Trichoderma spp. as a bioformulation against pathogens that cause wilt and root rot in cucumber [F. oxysporum f. sp. cucumerinum (72%) and P. aphanidermatum (66%)] against.</div>","PeriodicalId":8598,"journal":{"name":"Australasian Plant Pathology","volume":"54 1","pages":"45 - 62"},"PeriodicalIF":0.9,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the excessive use of these products causes decline of their efficacy and environmental pollution issues. Then, aiming to seek for alternatives on the control of ASR, the efficiency of using copper (Cu) in the form sparingly soluble microparticulate oxide (CuO) on protecting against the disease was compared to soluble sulfate (CuSO4.5H2O, CuS). The inoculation with urediniospores of Phakopsora pachyrhizi was performed 5 days after the spray with solutions containing 0.5 g L− 1 of Cu for either sources or deionized water as a control (CT). Disease symptoms severity was assessed until 30 days after inoculation, when leaf tissue was sampled for studying mesophyll integrity. Further, in vitro tests were conducted to assess the impact of CuO and CuS on the germination of urediniospores; and, a complementary experiment evaluated the concentration of Cu in the sprayed leaves as function of the source. Results revealed that both tested compounds were capable of completely inhibiting urediniospores germination in vitro. However, CuO had greater efficiency to delay the onset of ASR symptoms and to reduce their severity, most likely because the treated leaves maintained greater Cu concentration than those receiving CuS. Moreover, Cu-sprayed leaves of inoculated soybean, regardless of the source, exhibited improved structural organization of the mesophyll compared to the CT. These findings suggest the potential of using CuO as an alternative to CuS for disease management programs with the aid of Cu-based products. Therefore, to refine the recommendations of sparingly soluble Cu sources, further studies remain crucial to reveal the mechanisms by which the protection against the disease is achieved.</div>","PeriodicalId":8598,"journal":{"name":"Australasian Plant Pathology","volume":"54 1","pages":"25 - 31"},"PeriodicalIF":0.9,"publicationDate":"2024-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study characterised blackleg disease progression from leaf lesion appearance to crown canker development. Leaf lesion severity at four crop growth stages and crown canker severity were empirically associated in crops planted at different times. The biotrophic growth rate of L. maculans in planta was determined at temperatures between 12 and 28 °C. Data from 24 Australian field experiments on spring B. napus cultivars were analysed to relate infection timing relative to crop growth stage and site conditions to crown canker severity at maturity. Despite variations in lesions across seasons and planting times, no significant relationship was found between lesion severity or incidence and crown canker severity. Crown canker severity increased significantly when younger plants were infected. The average in planta hyphal growth rate of L. maculans was 0.13 mm/°C-day. The analyses of biotrophic hyphal growth alongside the timing of infection were used to identify the onset of crown canker development. Simulations showed that thermal time and plant available water accounted for 61% and 36% of the variance in crown canker severity for moderately susceptible and moderately resistant genotypes, respectively. Blackleg crown canker severity is a nuanced interplay between time of infection relative to crop growth stage, genetic resistance, temperature, and moisture. Disease-crop models incorporating these factors could be used to explore how, for example, sowing time, level of host genetic resistance or extreme weather conditions affect disease infection and crop yield.</div>","PeriodicalId":8598,"journal":{"name":"Australasian Plant Pathology","volume":"54 1","pages":"13 - 24"},"PeriodicalIF":0.9,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13313-024-01013-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BRR of cotton was reported for the first time in northern New South Wales (NSW), Australia in 1990. Now, the disease is widespread across cotton growing regions in NSW. Much research has focused exclusively on control management; however, relatively little work has been conducted to understand the BRR pathogen population for their temporal and spatial distributions. A total of 294 B. rouxiae isolates that were freshly collected across NSW over five cropping seasons (2017–2022) were assessed for their genetic diversity based on sequences of the nuclear ribosomal DNA internal transcribed spacer, mini-chromosome maintenance complex component 7, translation elongation factor 1-alpha and RNA polymerase II second largest subunit. Additionally, these isolates were subjected to a specific duplex PCR assay for mating type determinations. Multiple sequence alignments revealed that the prevailing cotton-B. rouxiae was 100% identical; however, the population can be divided into two subgroups based on the presence of mating idiomorphs. The MAT1-1 type was predominant and accounted for 62.2% of the population. A total of 25/77 fields were confirmed to harbour both MAT1-1 and MAT1-2 isolates. However, we failed observe sexual structures in crossing experiments. Based on the sequence uniformity of the cotton-B. rouxiae population, we suggest that the pathogen has spread from one field to another.
