Mikhaelmohamed_faah@yahoo.comMohamed F. A. Ahmedmohamed_faah@yahoo.com<p>This investigation's goal is to assess the effectiveness of eco-friendly treatments, <em>i.e., </em>biocide Blight stop, three natural oil extracts: black seeds, thyme and eucalyptus oils, as well as fungicide Opus 12.5% Sc in reducing powdery mildew infection on susceptible Egyptian barley varieties. These treatments were carried out under greenhouse and field experiments conducted at Giza Experimental Station, Agricultural Research Centre (ARC), during the 2020/2021 and 2021/2022 growing seasons. All eco-friendly treatments and fungicide reduced disease severity percentage, area under the disease progress curve (AUDPC) and average coefficient of infection (ACI) compared to the control treatment in the two seasons, in addition to increasing yield, total chlorophyll and carotenoids compared to the control treatment. Spraying fungicide Opus provided the most effective treatments, followed by biocide-Blight stop. On the other hand, thyme oil was recorded as having the least effectiveness in comparison to the control treatment during both seasons.</p>2023-07-01T00:00:00+00:00Copyright (c) 2023 Journal of Phytopathology and Disease Managementhttps://ppmj.net/index.php/ppmj/article/view/243Morpho-molecular identification and management of Erysiphe heraclei causing dill powdery mildew using a biocide, essential oils, and organic acids2023-11-06T21:24:52+00:00Mahmoud Hassanindr.hassanin.1978@gmail.comAbdallah Aliabdallahali@agr.aswu.edu.egHeba Yousefabdallahali@agr.aswu.edu.egMadian Mergawyabdallahali@agr.aswu.edu.eg<p>This study aimed to evaluate the efficacy of Bio-Cure F, essential oils of thyme and clove, ascorbic and salicylic acids in controlling dill powdery mildew under greenhouse conditions. The causal pathogen of powdery mildew was isolated from infected dill plants showing symptoms of the disease during a survey in Fayoum governorate, Egypt, in 2022. <em>Erysiphe heraclei</em> was morphologically characterized using a light microscope as the causal pathogen of powdery mildew in infected dill plants. The nucleotide sequence of the internal transcribed spacer (ITS) of the causal pathogen DNA was deposited in GenBank (Accession No. OP999071.1), which showed 98-100% similarity with accession numbers of <em>E. heraclei</em> isolates obtained from the NCBI database. Under greenhouse conditions, dill plants were sprayed with biocide (Bio-Cure F), elicitors (ascorbic and salicylic acids), and essential oil emulsions of clove and thyme three times after inoculation with <em>E. heraclei</em>. The results showed that Bio-Cure F was the treatment that showed the highest efficacy in reducing both disease severity and incidence percentage, followed by thyme essential oil. The highest percentages of increase in dill plant height (cm) as well as branches/plant were obtained by Bio-Cure F treatment compared to the control, followed by salicylic acid treatment. The results suggest that Bio-Cure F, salicylic acid, and thyme oil emulsion could be used to control dill powdery mildew.</p>2023-07-01T00:00:00+00:00Copyright (c) 2023 Journal of Phytopathology and Disease Managementhttps://ppmj.net/index.php/ppmj/article/view/231In vitro and in vivo antifungal activity of microalgal treatments against Alternaria brassicicola2023-08-24T06:07:18+00:00Yesim ERy_err@hotmail.com<p>Commercial preparations of three algal species (<em>Arthrospira </em><em>platensis, Chlorella vulgaris, </em>and<em> C. pyrenoidosa)</em> were evaluated according to <em>in vitro</em> (paper disc method), and <em>in vivo </em>(seed, foliar, seed+foliar treatments) assays to determine the antifungal activity against<em> Alternia brassicicola. </em>For <em>in vitro</em> assays, the extracts of <em>A. </em><em>platensis, C. pyrenoidosa, </em>and <em>C. vulgaris</em> showed the highest antifungal activity, inhibiting the growth of <em>A. brassicicola </em>at a concentration of 50 mg/ml with inhibition zones of 4.9, 4.2, and 3.9 cm, respectively. For <em>in vivo</em> assays, the microalgal suspensions were observed to have remarkable antifungal activity at increasing concentrations against <em>A. brassicicola</em> compared with control treatments. Particularly, the seed+foliar treatment of a mixture of the microalgal suspension (<em>A. </em><em>platensis+ C.vulgaris+ C. pyrenoidosa</em>) at a concentration of 15 g/l demonstrated the highest antifungal activity with an inhibition rate above 98% in cabbage (<em>Brassica oleracea</em>) and mustard (<em>Brassica</em> <em>juncea</em>). The present study confirmed that the microalgae treatments had a significant potential, as an applicable and eco-friendly tool against <em>A. brassicicola,</em> to reduce exposure and risks of chemical pesticides.</p>2023-07-01T00:00:00+00:00Copyright (c) 2023 Journal of Phytopathology and Disease Managementhttps://ppmj.net/index.php/ppmj/article/view/232Arthropod fauna and rats in organic sugarcane in Tahiti2023-05-03T06:46:59+00:00Marotea Vitracmaroteav@gmail.comTaivini Teai Teaitaivini.teai@upf.pfInes Shili-Touzii.shilitouzi@istom.frFrançois-Régis Goebelregis.goebel@cirad.fr<p>As organic sugarcane is promised to an important development in French Polynesia thank to the high-quality rum produced in this part of the world, preliminary studies on main biotic constraints were conducted on this crop between 2018 and 2021 to better apprehend their control. Visual observations at regular intervals and captures using different types of traps were carried out to collect and identify the arthropod fauna in Tahiti Island. With no surprise, stemborer insects were the most important pests of sugarcane in these different areas. We were also able to identify key predators and parasitoids that are important to preserve for natural control of these pests. Stem borers and rats are a big concern in most islands and like the other pests, we make propositions here to implement some tactics of agroecological crop protection.</p>2023-07-01T00:00:00+00:00Copyright (c) 2024 Journal of Phytopathology and Disease Management
