Sheath blight of rice (Oryza sativa L.) is a major rice disease throughout the world including the southern United States. This disease, which is caused by Rhizoctonia solani Kühn (teleomorph: Thanatephorus cucumeris (Frank) Donk), was first reported in 1910 and now occurs throughout temperate and tropical production areas, being most prominent where rice is grown under intense, high-fertility ...

Actinobacteria produce a broad spectrum of bioactive substances that are used in the pharmaceutical, agricultural, and biotechnology industries. This study investigates production Streptomyces, isolated from soil under five tropical plants, focusing on their potential as natural antibacterial dyes for silk fabrics. Out 194 isolates, 44 produced pigments broken rice solid substrate culture. Eigh...

This work presents results on the effect of manganese ions on the development and biological activities of the fungal antagonists Trichoderma harzianum, Trichoderma pseudokoningii and Trichoderma viride. The effects of manganese on linear growth of Trichoderma spp. depend on the metal concentration and the fungal species. T. harzianum proved the most sensitive fungus. on the other hand, none of...

rhizoctonia-like fungi were isolated from the infected roots of miniature rose (rosa hybrida cv. linda) plant with chlorosis and necrosis symptoms, grown in commercial glasshouse in rafsanjan, iran, during the autumn of 2011. all of the isolates were identified as binucleate rhizoctonia sp. on the basis of hyphal characteristics and nuclei number. they were tested for detection of the anastomos...

In January 2021, unusual outbreak of shoot rot symptoms was observed in young spikenard (Aralia cordata) plants growing vinyl greenhouses located Chuncheon and Yanggu, Gangwon Province, Korea. The initially appeared on shoots the at or above soil surface level. Later, infected wholly rotted blighted. incidence diseased investigated ranged from 5% to 30%. Eight isolates Rhizoctonia sp. were obta...

Filamentous actinomycetes are commercially widely used as producers of natural products (in particular antibiotics) and of industrial enzymes. However, the mycelial lifestyle of actinomycetes, resulting in highly viscous broths and unfavorable pellet formation, has been a major bottleneck in their commercialization. Here we describe the successful morphological engineering of industrially impor...

Abstract Background Botrytis cinerea , the causal agent of grey mould, is a polyphagous fungus that infects wide range plants, including tomato. In many countries, Algeria, management mould challenging problem, even with chemical control. This necessitates search for other strategies. The objective this study was to evaluate biocontrol potential two rhizospheric bacterial isolates protection to...

Early blight, caused by Alternaria solani is one of the destructive diseases potato. An in vitro experiment was conducted using poisoned food technique to evaluate efficacy acetone extracts six plant species on mycelial growth A. solani. Plant Artemisia vulgaris, Melia azedarach, Parthenium hysterophorus, Datura stramonium, and Justicia adhatoda at concentrations 0.1%, 0.5% 5% prepared from Sox...
