The advancement of eco-friendly techniques for creating nanoparticles is a crucial step in the progress of nanotechnology as a dependable, environmentally sustainable method for producing a large variety of biocompatible materials and nanomaterials, including metal/metal oxide nanomaterials and nanocomposites. Therefore, green synthesis is viewed a...

Controlling the hazard of sclerotia produced by the Sclerotinia sclerotiorum is very complex, and it is urgent to adopt an effective method that is harmonious environmentally to control the disease. Among the six isolates isolated from the rhizosphere of lettuce, the isolate HZA84 demonstrated a high activity in its antagonism towards Sclerotinia s...

Verticillium dahliae is a soilborne fungal pathogen that causes vascular wilt diseases in a wide range of economically important crops, including eggplant. Trichoderma spp. are effective biological control agents that suppress a wide range of plant pathogens through a variety of mechanisms, including mycoparasitism. However, the molecular mechanism...

To control the disease caused by Sclerotinia sclerotiorum, a total of 15 isolates of the Trichoderma species was screened for the biosynthesis of silver nanoparticles (AgNPs). Among them, the highest yield occurred in the synthesis of AgNPs using a cell-free aqueous filtrate of T.virens HZA14 producing gliotoxin. The synthetic AgNPs were charactere...

Bacterial brown stripe disease caused by Acidovorax oryzae is a major threat to crop yields, and the current reliance on pesticides for control is unsustainable due to environmental pollution and resistance. To address this, bacterial-based ligands have been explored as a potential treatment solution. In this study, we developed a protein–protein i...

These authors contributed equally to this work. Abstract: The environmental impact of industrial development has been well-documented. The use of physical and chemical methods in industrial development has negative consequences for the environment, raising concerns about the sustainability of this approach. There is a growing need for advanced tech...

Ralstonia solanacearum is the most destructive pathogen, causing bacterial wilt disease of eggplant. The present study aimed to develop green synthesis and characterization of silver chloride nanoparticles (AgCl-NPs) by using a native bacterial strain and subsequent evaluation of their antibacterial activity against R. solanacearum. Here, a total o...

A new species of Trichoderma and gliotoxin role: A new observation in enhancing biocontrol potential of T. virens against Phytophthora capsici on chili pepper

The Bipolaris australiensis was isolated and identified for the first time from the palm infected leaves with spotted disease in Misan province- Iraq. The responsibility of a fungus as causing the disease was confirmed by the results of the pathogenicity test in vitro. To control of this pathogen, three kinds of strategies followed to inhibit radia...

Phytophthora capsici is a phytopathogen causing a destructive pepper blight. To control this disease, 77 isolates of Trichoderma spp. were isolated from rhizosphere soil and 15 isolates showed high antagonistic activity. Based on the analysis of the rDNA internal transcribed spacers (ITS), translation elongation factor 1-α (TEF1) and RNA polymerase...

Bacterial wilt of eggplant is the most destructive disease caused by Ralstonia solanacearum throughout the world. Eleven bacterial strains with high antagonistic activity were obtained from 245 rhizobacteria. Based on analysis of morphology, 16S rRNA sequences, fatty acid profiles, gyrA and rpoB genes, they were identified as Pseudomonas putida (IM...

The current study was conducted in date palm groves in Misan Governorate, Iraq, where the fungus Bipolaris australiensis was isolated as a cause of palm leaf spot disease. The results of the pathogencity test showed the ability of the fungus to cause the disease, while the use of Swift Sc pesticide (Carbendazim 50%) in the laboratory showed that th...

The percentage of purity in the treatment of burnt cane harvested in the time period of 24 hours hours of transportation to 76.52% while it decreased by significantly Differences...

The Present work studied the biological agent T. viride (T.V) and antifungal activity of the aqueous extract plant(PE) obtained from rough Cocklebur X. strumarium L. against the R. solani (R.S) caused by damping-off on Okra in the PDA and greenhouse. That T. viride has antagonistic activity against R. solani were attain 100% in the PDA. All tested...
