This study was conducted at the University of Baghdad, College Agricultural Engineering Sciences/Department Plant Protection for period 2021-2022, with aim isolating and diagnosing pathogens that cause root rot wilt disease on Catharanthus roseus in different areas conducting an integrated control pathogen using biological chemical control. The results isolation identification presence 4 types ...

Extracts from eleven different plant species such as jute (Corchorus capsularis L.), cheerota (Swertia chiraita Ham.), chatim (Alstonia scholaris L.), mander (Erythrina variegata), bael (Aegle marmelos L.), marigold (Tagetes erecta), onion (Allium cepa), garlic (Allium sativum L.), neem (Azadiracta indica), lime (Citrus aurantifolia), and turmeric (Curcuma longa L.) were tested for antibacteria...

Fungicide-resistant Alternaria alternata impede the practical control of the Alternaria diseases in crop fields. This study aimed to investigate cytological fungicide resistance mechanisms of A. alternata against dicarboximide fungicide iprodione. A. alternata isolated from cactus brown spot was cultured on potato-dextrose agar (PDA) with or without iprodione, and the fungal cultures with diffe...

The fungicidal effect of some essential oils against Alternaria solani one of the species that cause early blight of potato was evaluated under in vitro and field conditions. Effect of carnation, caraway, thyme oils and the chemical fungicide Ridomil MZ 72 at various concentrations on mycelial growth of A. solani was tested. Carnation oil had the strongest and most extensive inhibitory effect o...

Natural products obtained from plants constitute an alternative to chemically synthesized fungicides, whose improper use might have caused the development of resistant fungal strains. In present work, 40 20 native Argentinean plant species were tested against three citrus postharvest pathogens: Penicillium digitatum, italicum, and Geotrichum citri-aurantii. by classical solvent extraction metho...

Epicoccum purpurascens stain 5615 AUMC was investigated for its biocontrol activity against root rot disease caused by Pythium irregulare. E. purpurascens greenhouse pathogenicity tests using three leguminous plants indicated that the fungus was nonpathogenic under the test conditions. The germination rate of the three species of legume seeds treated with a E. purpurascens homogenate increased ...

Pectobacterium species are necrotrophic bacterial pathogens that cause soft rot diseases in potatoes and several other crops worldwide. Gene expression data identified Pectobacterium carotovorum subsp. carotovorum budB, which encodes the α-acetolactate synthase enzyme in the 2,3-butanediol pathway, as more highly expressed in potato tubers than potato stems. This pathway is of interest because ...

Magainin peptides originally identified from Xenopus laevis have cytotoxic effects against a range of prokaryotic organisms without harmful effects on higher eukaryotes. The mechanism of cytotoxicity of the peptides is by disruption of membranes, which causes osmolysis. Magainin peptides are known to inhibit the in vitro growth of many phytopathogens including Erwinia carotovora, the causative ...
