Twenty sorghum seed samples were collected in 2015 from sorghum fields in southern region of Saudi Arabia and investigated for seed-borne fungi. Thirteen fungal genera and twenty-one fungal species were recorded on sorghum seeds using agar plate...
The Sclerotium tuber rot fungus (Sclerotium rolfsii Sacc.) represents a serious problem for Jerusalem artichoke (JA) tubers during storage periods. The aim of this study was to investigate an alternative preservation method using a natural essential...
White mold, caused by Sclerotinia sclerotiorum (Lib.) de Bary, is the most globally significant disease of Jerusalem Artichoke (JA) causing considerable losses during storage periods. The aim of this study was to evaluate the use of a natural...
Antagonistic actinomycete strains isolated from the environment are valuable tools for an eco-friendly, healthy, and safe control of phytopathogenic fungi. We have evaluated the culture filtrate of Streptomyces griseorubens E44G, an actinomycete...
Stem canker and black scurf of potato, caused by Rhizoctonia solani, can be serious diseases causing an economically significant damage. Biocontrol activity of Bacillus subtilis ATCC 11774 against the Rhizoctonia diseases of potato was investigated...
The antifungal activity of Streptomyces griseorubens E44G against Rhizoctonia solani, the causal agent of root rot disease of corn, was investigated. The mycelial growth of R. solani was inhibited by S. griseorubens E44G, indicating that it has an...
ABSTRACT Under field production phase, wilt, stalk and tuber rots diseases lead to considerable decline in Jerusalem artichoke (JA) yield and quality, and subsequently reduce storability of tubers. This study aimed to test and prepare suitable...
ABSTRACT
Rust-infected wheat leaves caused by Puccinia triticina Eriks. were collected throughout the survey of nurseries at Tag El-Ezz Agricultural Research Station, Dakahlia Governorate, Egypt, in order to evaluate and test the efficiency of leaf...
Five pathogenic fungi (Alternaria alternata, Bipolaris sorokiniana, B. spicifera,
Fusarium avenaceum and F. graminearum) were evaluated for seed discoloration,
shriveling, germination and seedling vigor of wheat. Three wheat cultivars (Yecora Rojo,...
In this study, a wide survey was conducted along Saudi Arabia. One hundred
soil samples were collected from different 18 governorates representing different climatic
conditions. Five hundred and seventy strains of actinomycetes were isolated from...
Sclerotium stem and tuber rot diseases caused by Sclerotium rolfsii is a
significant problem facing the Jerusalem artichoke cultivation. The objective of this study
was to evaluate the efficacy of biotic and a biotic agents in control of stem and...
Summary
One hundred samples of tomato seeds were collected
in 2011 and 2012 from tomato-cultivated fields in
Saudi Arabia and screened for their seed-borne
mycoflora. A total of 30 genera and 57 species of fungi
were recovered from the collected...
Alkaline protease enzyme was produced under solid state fermentation by
Fusarium solani. Various agro-wastes were evaluated to check their potential utilization
in the solid state fermentation for protease production. In this connection, the results...
In vitro antimicrobial activity of methanolic extracts of six medicinal plants
(black seed, camphor, cloocynth, clove, ginger and white cedar) were investigated against
pathogenic bacteria and fungi at 3, 6 and 9% concentrations. Results obtained in...
Abstract: In the present study Fusarium oxysporium was used for bioproduction of nano-silver particles. Electron microscopey observation showed particles with sizes ranged from 16-30 nm. Antimicrobial activity of these particles was investigated...
