Molecular Identification of Fungal Pathogens of Date Palm Root Rot in Egypt

Journal of Plant Protection and Pathology /Journal of Plant Protection and Pathology, Journal Year: 2024, Volume and Issue: 0(0), P. 155 - 162

Published: May 21, 2024

In tropical and subtropical regions, date palm is a highly significant fruit tree, known for its more than 3,000 different varieties found around the world. However, in Egypt, palms are susceptible to infection by root rot disease (RRD) caused various harmful soil borne fungi. This leads damage both trees their offshoots. The most fungi Egypt included: Fusarium oxysporum, which causes deterioration of roots, as well F. moniliforme, solani, Thielaviopsis paradoxa, Botryodiplodia theobromae Rhizoctonia solani. A survey collection samples was carried out five districts (Kharga, Baris, Balat, Dakhla Frafra) within New Valley Governorate, were out. Pathogenicity tests severity confirmed presence 15 fungal species belonging six genera, identified Acrocalymma vagum, Curvularia australiensis, C. lunata, spicifera, Exserohilum rostratum, Marasmius palmivorus Talaromyces pinophilus. Through molecular identification using internal transcribed spacers (ITS), it has been determined that these eight new pathogenic isolates, not previously belong species: A. E. M. palmivorus, T. finding represents first documented association with RRD Egypt.

Análises microbiológicas de bionsumos multiplicados a partir de Bacillus e Trichoderma em biofábricas na região de Curitibanos – SC

Saúde e meio ambiente revista interdisciplinar, Journal Year: 2024, Volume and Issue: 13, P. 131 - 149

Published: Oct. 21, 2024

O desenvolvimento do agronegócio brasileiro tem sido cada vez mais pautado no uso de microrganismos na agricultura. Com a crescente demanda por produtos biológicos, muitos agricultores passaram multiplicar bactérias e fungos em suas propriedades biofábricas, um sistema conhecido como on farm. Entretanto, essas instalações são comumente desprovidas qualquer controle sanitário isso resulta baixíssima multiplicação microrganismo alvo predominância contaminantes. Nesse contexto, o objetivo presente trabalho foi analisar qualidade multiplicados partir à base Bacillus Trichoderma região Curitibanos – SC. As análises compreenderam aspectos pH, coloração quantificação multiplicados, tanto os provenientes produto original contaminantes, com características morfológicas das colônias. A maior parte amostras não apresentava que produtores desejavam propagar, todas as analisadas apresentavam Os dados revelam biofábricas eficiente para gerar bioinsumos concentração adequada. Esses se utilizados áreas agrícolas, contaminarão solo, plantas e, possivelmente, recursos hídricos, representam considerável risco saúde ambiental, bem humana.
