“…In the two successive seasons 2020 and 2021 compared to control treatment, Blight stop was the best treatment in increasing activity of PO (1.97 and 1.99), PPO (0.23 and 0.25) and total phenol (3.43 and 3.45) more than other treatments, while humic acid was the lowest effective one compared with untreated plants. The obtained results are in agreement with those obtained by El-Mslmany et al (2020) who insured that the application of biological control effects on powdery mildew of mango plants in addition to increasing its chemical content (Kaur et. al., 2018).…”

“…On the contrary, humic acid showed the least efficacy (52.41 and 75.43%) in controlling the disease. The field results can be interpreted according to both the effect of biotic factors which produce growth regulators and the chemical effect of antioxidants (Kaur et. al., 2018), which play a clear role in improving plant physiology, metabolism and induce systemic resistance (ISR) (Nofal and Haggag, 2006) .…”

This investigation was conducted in a private organic farm in Wadi El-Malak district, Ismailia Governorate, Egypt, to evaluate some biocontrol agents i.e. Trichoderma album, T. harzianum, T. viride , biocides i.e. Blight stop (T. harzianum), Bio Zeid (T. album) and natural compound i.e. humic acid and micronic sulfur treatments in the controlling powdery mildew disease of mango cv. Keitt during the two successive seasons in 2021 and 2022. All treatments proved effective in decreasing the Incidence and severity of powdery mildew disease caused by Oidium mangiferae and increased productivity, yield components, quality, chemical components, and enzyme activity of mango cv. Keitt compared to untreated plants. Mango cv. Keitt which was treated with blight stop at the rate of 1: 50 caused the highest decrease in disease incidence, severity (71.01 and 92.10%) and recorded also, the highest increase in yield being 35.5 Kg/tree; fruit quality "total soluble solids (TSS), being 19.50 and 20.46%, total acidity, being 0.71 and 0.73%, ascorbic acid being 54.68 and 54.77 mg/100g FW and total sugar, being 14.60 and 14.70%"; biochemical analysis i.e. total chlorophyll (4.71 mg/100 g FW), total carotenoids (6.77 mg/100 g FW and total protein (3.38%); total phenol content and the enzyme activities of peroxidase (PO) and polyphenol oxidase (PPO) during both growing seasons, followed by T. harzianum isolate. On the contrary, humic acid showed the least effective treatment. No clear significant differences were noticed between the other treatments in comparison with untreated plants.

Fungi Parasitizing Powdery Mildew Fungi: Ampelomyces Strains as Biocontrol Agents against Powdery Mildews

Among the mycoparasites, Ampelomyces strains are studied in detail, particularly regarding their use as biocontrol agents (BCAs) of powdery mildew (PM) fungi, including their potential to replace conventional agrochemicals. Ampelomyces strains are characterized morphologically; their ribosomal DNA internal transcribed spacer (rDNA-ITS) regions and actin gene (ACT) fragments were sequenced and their mycoparasitic activity was analyzed. In the interaction between Ampelomyces strains and PM fungi, the spores of the mycoparasites germinate on plant leaves, and their hyphae then penetrate the hyphae of PM fungi. Ampelomyces hyphae continue their growth internally, initiating the atrophy of PM conidiophores and eventually their complete collapse. Following the successful destruction of PM hyphae by Ampelomyces, the mycoparasite produces new intracellular pycnidia in PM conidiophores. The progeny spores released by mature pycnidia become the sources of subsequent infections of intact PM hyphae. As a result, the number of Ampelomyces-inoculated PM colonies gradually declines, and the conidial release of PM colonies is inhibited after the first treatment. Almost all conidiophores of 5- and 10-day-old Ampelomyces-inoculated PM colonies undergo complete atrophy or collapse. Methodological advances and in-depth analyses of the Ampelomyces–PM interaction were recently published. In this review, we summarize the genetic and phylogenetic diversity, the timing of mycoparasitism and pycnidiogenesis, the results of quantitative and visual analyses using electrostatic and digital microscopy technologies, the PM biocontrol potential of Ampelomyces, and the potential commercialization of the mycoparasites. The information provided herein can support further biocontrol and ecological studies of Ampelomyces mycoparasites.
