The grapevine trunk diseases (GTD) Botryosphaeria dieback and esca threaten the sustainability of industry worldwide. This study aimed to evaluate compare efficacy various liquid (pyraclostrobin + boscalid thiophanate methyl) paste (paste tebuconazole) formulation fungicide treatments as well biological control agents (Trichoderma atroviride SC1 T. I-1237), for their potential prevent infection...

samples were collected from soil and as well from phyllosphere of rice plant and subjected to dilution plate technique on rbsf trichoderma selective medium. a total of 202 trichoderma isolates were obtained from rice fields at different geographical locations distributed all over mazandaran province. single spore isolates were obtained and genomic dna extracted from all the isolates using dna e...

The antagonistic potential of seven species native Trichoderma against Rhizoctonia solani f.sp. sasakii were evaluated in dual culture method which includes T. asperellum (KU933476), koningiopsis (KU904460), Hypocrea lixii (KX0113223), harzianum (KU933471), ovalisporum (KU904456), (KU904458), atroviridae (KU933472). Among them showed highest inhibition percentage (78.09%), followed by (70.95%),...

The antagonistic potentialities of seven species native Trichoderma viz., T. atroviride, koningiopsis, ovalisporum, Hypocrea lixii, harzianum, asperellum and harzianum were evaluated in vitro against Cochliobolus heterostrophus causing maydis leaf blight maize. current study dual culture assay, revealed the percentages mycelial growth inhibition C. by atroviridae, asperellu 80.4%, 83.80%, 82.85...

Plants are constantly exposed to microbes, for this reason they have evolved sophisticated strategies to perceive and identify biotic interactions. Thus, plants have large collections of so-called resistance (R) proteins that recognize specific microbe factors as signals of invasion. One of these proteins is codified by the Arabidopsis thaliana HR4 gene in the Col-0 ecotype that is homologous t...

Abstract Background Early blight disease of tomato caused by pathogenic fungi Alternaria solani is the most significant and common throughout world as well in Kingdom Saudi Arabia. The aim this study was to isolate identify native Trichoderma species from Jeddah region Arabia; evaluate their antagonistic potential against A. ; influence early severity greenhouse open field. Results present focu...

Xylotrophic fungi are well known by their ability to excrete enzymes into environment. These have important biotechnological potential and some of them produce industrial enzymes. Besides, xylotrophic fungal species recently attracted a lot attention among researchers as source antibacterial drugs. Aim. To analyze the effect carbon in culture medium, conditions deep cultivation on mycelium yiel...
