“…In Malaysia, Alternaria capsicicola is a causal agent of leaf spot of C. annum [9], while A. alternata is the common pathogen of C. annum leaf spot [10]. On the other hand, Botrytis cinerea is the dominant causal agent of Capsicum gray mold in different parts of the world [11][12][13][14][15]. Botrytis pelargonii has also been reported associated with gray mold in some crops [16].…”

The aim of this study was to assess the ability of Bacillus amyloliquefaciens, to augment plant growth and suppress gray mold and leaf spot in pepper plants. Morphological modifications in fungal pathogen hyphae that expanded toward the PGPR colonies were detected via scanning electron microscope. Furthermore, preliminary screening showed that PGPR could produce various hydrolytic enzymes in its media. Treatments with B. amyloliquefaciens suppressed Botrytis gray mold and Alternaria leaf spot diseases on pepper caused by Botrytis pelargonii and Alternaria alternata, respectively. The PGPR strain modulated plant physio-biochemical processes. The inoculation of pepper with PGPR decreased protein, amino acid, antioxidant, hydrogen peroxide, lipid peroxidation, and abscisic acid levels but increased salicylic acid and sugar levels compared to those of uninoculated plants, indicating a mitigation of the adverse effects of biotic stress. Moreover, gene expression studies confirmed physio-biochemical findings. PGPR inoculation led to increased expression of the CaXTH genes and decreased expression of CaAMP1, CaPR1, CaDEF1, CaWRKY2, CaBI-1, CaASRF1, CaSBP11, and CaBiP genes. Considering its beneficial effects, the inoculation of B. amyloliquefaciens can be proposed as an eco-friendly alternative to synthetic chemical fungicides.

“…More specifically, grey mold is a major pre-and post-harvest disease caused by Botrytis cinerea Persoon (Mercier et al 2001). Symptoms on the fruit include soft, water-soaked lesions, turning brown before being covered with powdery, grey masses of spores (Naz et al 2018). Alternaria fruit rot is caused by species of Alternaria, including Alternaria alternata (Fries) Keissler (Fallik et al 1994;Troncoso et al 2005).…”

Bell pepper (Capsicum annuum L.) fruit are susceptible to various molds, including grey mold and Alternaria rot. In this work, antagonistic bacteria isolated from disease-suppressive composts were assessed for their ability to reduce the mycelial growth of Botrytis cinerea Persoon and Alternaria alternata (Fries) Keissler as well as to suppress grey mold and Alternaria rot on bell pepper. Results showed that different bacterial antagonists reduced mycelial growth of B. cinerea and A. alternata by up to 49% and 53%, respectively. The bacteria provided inhibition of grey mold, reducing incidence and severity by as much as 43% and 67%, respectively. The isolates also provided strong inhibitory effects against Alternaria rot, decreasing incidence and severity by as much as 77% and 80%, respectively. Pseudomonas and Arthrobacter spp. were particularly suppressive to Alternaria rot. Results of this study suggest antagonistic bacteria may represent a potential method for controlling fruit rot of bell pepper.
