Arbuscular Mycorrhizal Technology in Sustainable Agriculture: Current Knowledge and Challenges in Agroforestry
(Springer Nature, 2024) Boyno, G.; Ansari, R.A.; Durak, E.D.; Güneş, H.; Çevik, R.; Demir, S.
In agroecosystems, arbuscular mycorrhizal fungi (AMF) are the most common and ubiquitous. Because of their productive and comprehensive symbiotic connections with plants, AM technology looks to be a viable option for sustainable agriculture and agroforestry. The commercialization of this technology may be utilized in agriculture, horticulture, and agroforestry to improve land use management and reduce the need for synthetic chemicals for plant growth and disease control. Furthermore, while mycorrhiza inoculation of plants is a well-known procedure, developing an inoculum consistently under field circumstances remains a bottleneck for their wide range of applications. Mycorrhizal inoculum generation, on the other hand, is a complicated process that necessitates commercial enterprises having the requisite biotechnological skills and capacity to react to ethical, educational, legal, and commercial needs. The aim of this chapter is to compile the available data on the theme of commercialization of AM technology as a tool and its use in increasing plant growth and yield characters. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
The Effect of Clonostachys Rosea (Sch.) Schroers and Samuels Against Verticillium Wilt (Verticillium Dahliae Kleb.) and Early Blight [Alternaria Solani (Ell. and G. Martin) Sor.] Diseases in Tomato Plants
(Centenary University, 2022) Çevik, R.; Demir, S.; Türkölmez, Ş.; Boyno, G.
The effectiveness of Clonostachys rosea against Verticillium wilt (Verticillium dahliae) and early blight (Alternaria solani) diseases, as the two most important problems in tomato cultivation with significant economic losses, was determined. It was determined that C. rosea was effective on A. solani and V. dahliae and suppressed mycelial growth. Also, the C. rosea on wheat grains inoculated to plants at 20 g, 30 g, and 40 g concentrations before and after pathogens inoculation. Then, fungal discs (2 mm in diameter) from V. dahliae growing colonies were inoculated on the host plant root zone. A. solani was also inoculated (1x106 conidia ml-1 ) by spraying the foliar parts of the plants. Results showed that V. dahliae caused 76.0% disease severity in control plants, while the disease severity indices were 58.3%, 55.3%, and 25.3% at 20 g, 30 g, and 40 g C. rosea application, respectively. In A. solani x C. rosea treatments, the disease severities were determined as 96.6%, 63.3%, 43.6% and 46.6% in control, 20 g, 30 g, and 40 g application of C. rosea, respectively. The pathogen suppression rates by C. rosea at 30g application dose was 54.8% against A. solani and at 40 g application dose was 66.6% against V. dahliae. The effects of C. rosea on plant growth parameters were also determined. Results showed that C. rosea had a positive effect on the morphological parameters in tomato plants. © 2022, Centenary University. All rights reserved.
