Screening for fungal antagonists to control black mold disease and to induce the accumulation of antifungal compounds in onion after seed treatment

Abstract

Twelve isolates belonging to the genera

Trichoderma harzianum antagonistic activity and competition for seed colonization against seedborne pathogenic fungi of sunflower

“…Competitive and/or mycoparasitic interactions were previously observed between T. harzianum and several plant pathogens such as Pythium sp., Aspergillus niger and F. verticillioides on the seeds of pea, onion and maize, respectively (Lifshitz et al . 1986; Özer, 2011; Ferrigo et al . 2014).…”

“…However, there were mycoparasitism and low competition by TRIC8 during interaction with F. oxysporum. Competitive and/or mycoparasitic interactions were previously observed between T. harzianum and several plant pathogens such as Pythium sp., Aspergillus niger and F. verticillioides on the seeds of pea, onion and maize, respectively (Lifshitz et al 1986;€ Ozer, 2011;Ferrigo et al 2014). The new results about the inhibition of colonization by A. alternata, B. cynodontis, F. culmorum and F. oxysporum on sunflower seeds using seed treatment with TRIC8 show possible protection of young seedlings from seedling rot disease in this plant caused by these seedborne fungi.…”

“…It enhanced sunflower growth (Hazarhun and Özer 2016; Özer et al . 2021) and showed antagonistic effects against many pathogens (Özer 2011; Özer and Arın 2014; Hazarhun and Özer 2016; Özer et al . 2017, 2021; Aşkın et al .…”

Rhizosphere bacteria associated with Chenopodium quinoa promote resistance to Alternaria alternata in tomato

“…Early blight caused by A. alternata has great economic importance globally. This disease reduces the photosynthetic surface of the leaves and, in severe cases, leads to complete plant defoliation 17 . According to a field survey conducted in 2016–2017 in different regions of Pakistan, A. alternata was found to be the second most common pathogen isolated from leaves and fruits of tomato, with disease incidence ranging from 9 to 75% 18 .…”

Producción e identificación molecular de quitina desacetilasas en hongos fitopatógenos

“…También es conocido como un agente fitopatógeno causante de decoloración, deterioro de semillas y pudrición de semillas y frutos de interés industrial como cebollas (Ozer, 2011) y plantas de soya (Malenĉić y col., 2012) 1.4 Cultivo Sólido y líquido.…”
