“…Intentional supplementation of such microorganisms may improve the productivity and resilience of plants grown in hydroponic systems. Exposure to microorganisms in compost tea has been shown to suppress diseases such as damping-off, powdery mildew, root rots, and wilts in soilless vegetable production. − However, parameters such as compost type, aeration, and brewing time of the tea need to be optimized for biocontrol efficacy . Another challenge for hydroponic food production is that when plants are grown in greenhouses or indoor settings, they are generally not exposed to the natural ultraviolet (UV) spectrum, which is critical for plant growth, photosynthetic efficiency, and especially the biosynthesis of health-promoting antioxidant phytochemicals. , Exploring plant performances under different lighting regimes is thus warranted.…”

Hydroponic food production in greenhouses is challenged by reduced exposure to ultraviolet (UV) light and beneficial soil microorganisms, which predisposes plants to antioxidant deficiencies and disease susceptibility. The objective of this study was to investigate the effects of UV light exposure and compost tea treatment on hydroponically grown plants. Garnet Giant mustard greens were hydroponically grown in both indoor and outdoor greenhouse settings, with and without UV light blocking and supplementation of compost tea. Plants grown outside in greenhouses produced more dry mass than those grown indoors. Compost tea supplementation boosted nitrogen and mineral accumulations in the absence of UV-blocking. Increased UV exposure resulted in more red pigmentation and higher antioxidant activities of the mustard greens, while compost tea supplementation reduced antioxidant activities. Compost tea treatment increased beneficial bacteria and decreased fungal pathogens. Overall, exposure to UV radiation and beneficial microorganisms improved the performance and nutrient profile of the mustard greens.

“…These results follow Kim et al [43], who observed similar population densities of culturable bacteria in the mixture of oriental medicinal herb compost and vermicompost tea during incubation. Furthermore, Li et al [44] showed analogous results in microbial populations in maize straw CT, having the most total bacteria microbial populations, followed by actinomycetes and total fungi. It is clear that microbial communities found in a CT can be indirectly responsible for growth improvement with respect to the control because of their implication for the availability of nutrients as previously suggested by Hamid et al [19], especially due to K + content in the studied CT.…”

Compost Tea Induces Growth and Resistance against Rhizoctonia solani and Phytophthora capsici in Pepper

Compost teas (CTs) are organic solutions that constitute an interesting option for sustainable agriculture. Those that come from garden waste have been applied in vitro and in vivo on pepper plants to determine its suppressive effect against both Phytophthora capsici and Rhizoctonia solani. The studied CT showed relevant content in NO3−, K2O, humic acids, and microorganisms such as aerobic bacteria, N-fixing bacteria, and actinobacteria, which play a role in plant growth and resistance. This rich abundance of microbiota in the CT induced a reduction in the relative growth rate of both P. capsici and R. solani (31.7% and 38.0%, respectively) in in vitro assays compared to control. In addition, CT-irrigated plants displayed increased growth parameters and showed the first open flower one week before those treatments without CTs, which suggests that its application advanced the crop cycle. Concerning pathogen infection, damage caused by both pathogens became more apparent with a one-week inoculation compared to a four-week inoculation, which may indicate that a microbiological and chemical balance had been reached to cope with biotic stresses. Based on these results, we conclude that CT application induces plant growth and defense in pepper plants against P. capsici and R. solani because of its relevant soluble nutrient content and microbiota richness, which provides a novel point for plant nutrition and protection in horticultural crops.

“…Among the 17 articles on Verticillium disease, representing 84 experiments, in 72% of the cases, the amendments were suppressive, 21% had a non-significant effect, and only in 7% of the cases, organic amendments were found to increase disease incidence (Bonanomi et al, 2007). Composts were found to be suppressive against V. dahliae in several annual crops: tomato (Antoniou et al, 2017;Reddy, 2017;Kadoglidou et al, 2020), eggplant (Ikeda et al, 2015;Markakis et al, 2016;Kanaan et al, 2018;De Corato et al, 2018;De Corato et al, 2019), pepper (Capsicum annum L.) (Abada et al, 2018;Ojinaga et al, 2020;Tubeileh and Stephenson, 2020), cotton (Castaño and Avileś, 2013;Avileś and Borrero, 2017) and strawberry (Li et al, 2019).…”

The vascular disease Verticillium wilt of cacao (Theobroma cacao), caused by the soilborne fungus Verticillium dahliae, is often qualified as a “minor” disease. However, it can cause severe losses locally, for example, in western Uganda and northeast of the Democratic Republic of Congo. This disease is difficult to control, notably due to an extended host range and prolonged survival in the soil. Therefore, Verticillium wilt must be addressed through an integrated disease management strategy as employed for other tree crops such as olive. Few studies, nonetheless, have focused on how to confront this disease in cacao. This paper aims to provide an overview of our knowledge on Verticillium wilt on cacao and the integrated disease management strategies for preventing and controlling it. Promising avenues based on findings in other crops that could be adapted to cacao are also explored. Good agricultural practices, genetic resistance, biological control, induced resistance, and the use of organic amendments with or without biocontrol agents are discussed. Moreover, the potential benefits of some of these solutions toward the resistance to other cacao diseases, abiotic stress, and nutrition improvement are presented.
