“…). Compost tea is a possible alternative to synthetic chemical fungicides because of its antimicrobial activities (Siddiqui et al, 2009 andSeddigh andKiani, 2018). Microorganisms in compost teas may act through one or more biological control mechanisms, competing for nutrients and/or space (Al-Mughrabi et al, 2008).…”

“…Scheuerell and Mahaffee 2006; Al-Dahmani et al 2003). Still, research is not conclusive on this topic, for example Seddigh and Kiani (2018) observed a better suppression of powdery mildew in a greenhouse setting with ACTs compared to NCTs and NCTs can be more phytotoxic due to the presence of organic acids (Carballo et al 2009; Kannangara, Forge, and Dang 2006).…”

Compost teas (CTs) are fermented watery compost extracts that can be made with a wide variety of organic ingredients. These extracts are applied on plants to promote plant growth and increase protection against pathogens. Several studies have shown that the live micro-organisms present in these teas play an important role in plant protection. Still, our knowledge on the identity and functionality of bacterial communities in CTs remains limited. Moreover, CTs are a heterogeneous group, as various combinations of ingredients, fermentation parameters and application guidelines are possible and little is known on the current practices in commercially available products. Consequently, also the microbial communities in these commercially available CTs are unknown. Here, we surveyed 68 CTs on ingredients, claims and guidelines regarding preparation and application. This revealed that most products were sold in dried form which needed to be rehydrated by the customers. Moreover, kelp, humic acid, sugar and molasses, were common ingredients. Additionally, we investigated the bacterial communities of eight products, covering different ingredients and preparations, using sequencing and culture-based techniques. Bacterial communities were remarkably similar at genus level, with Pseudomonas, Massilia, Comamonas, Chryseobacterium, Brevundimonas and Acinetobacter as most prevalent genera. The genus Pseudomonas was more abundant in CTs that were prepared without aeration. Moreover, differences between liquid and dry products revealed the importance of formulation to secure the viability of the desired microbes. This study has given insight in common practices in CTs on the market, their microbial composition, and highlighted several discrepancies with current literature.

“…compost tea reducing the disease severity in the greenhouse (23.33% disease severity). Organic fertilizers are a possible alternative to chemical fungicides because of its content of antimicrobial activities (Siddiqui et al, 2008 andSeddigh andKiani, 2018). There are several mechanisms of microbial action such as microbial competition for nutrients, antibiotic production, antagonistic microbes" natural ability to produce extracellular lytic enzymes (El-Masry, 2002), parasitism and induction of systemic acquired resistance (Pharand et al, 2002) are among the major means by which compost extracts suppress plant pathogenic microorganisms.…”

Organic fertilizers are products consisting of living cells of many kinds of microorganisms that have the ability to convert complex important elements from unavailable to available forms through biological processes (Seddigh and Kiani, 2018).…”

The present study was conducted at a private farm in El-Khatateba -Sadat City-Menofyia Governorate location during 2019/2020 and 2020/2021 to evaluate the effect of foliar spraying with some organic fertilizers (green organic magic, green power and compost tea on growth, seed yield and seed quality of three dry beans cultivars (Giza 6, Giza 10 and Nebraska), as well as the impact of those fertilizers on the severity of the three cultivars of rust diseases. The obtained results showed a wide diversity among all tested cultivars in growth, yield and quality traits. All bean studied traits significantly affected by the differences organic fertilizer treatments in both seasons. Giza 6 cv. had the highest number of pods/plant, number of seeds/pods, number of seeds/plant and seed yield/fad in addition to the lowest percentages of disease severity and disease incidence of rust, in both seasons. Nebraska cv expressed the highest number, 100-seed weight as well as seed contents of; moisture, total protein, total carbohydrates, total soluble sugar and total phenolic in both seasons. Bean plants that treated with Green power gave the highest; number of pods/plant, number of seeds/plant, 100-seed weight, seed yield/fad and the highest seed contents of; moisture, total protein, total carbohydrates, total soluble sugar and total phenolic in both seasons. Bean plants that sprayed with Green power recorded the lowest disease severity and disease incidence and this reduction in both severity and incidence associated with the highest efficacy of disease reduction in both seasons. As for the interaction Giza 6 cv that treated with Green power had the highest; number of pods/plant and seed yield/fad in both seasons. Giza 6 cv that sprayed with Green organic magic recorded the lowest disease severity, disease incidence and the highest efficacy of disease reduction in both seasons. Nebraska cv that treated with Green power had the highest seed contents of moisture, total protein, total carbohydrates, total soluble sugar and total phenolic in both seasons. The results confirmed that seed yield/fed significant negative associated with rust disease severity
