“…It is a predominant causal agent pathogen of sheath blight (SB) and banded leaf and sheath blight (BLSB) on rice and corn worldwide and more especially in Asian countries (Jones and Belmar 1989;. However, the AG-1 IA group was reported to cause a foliar blight on snap bean and oil palm while on common bean caused web blight and root rot (Torres et al 2016;Quadros et al 2019;Boari et al 2017). In this study, Rhizoctonia solani AG-1 IA and ID AG-2 2IV, and BNR AG-Fa were isolated from spinach as a casual pathogen of foot root (basal petiole rot and leaf blight).…”

Rhizoctonia is a widespread soilborne fungus in different agroecosystems worldwide. It has been reported as a destructive fungal pathogen that caused various types of diseases on a wide variety of crops. The aim of this study was to characterize Rhizoctonia spp. isolated from various crops. We obtained 37 Rhizoctonia isolates from rice, corn, spinach, chrysanthemum, and chili grown in various locations in Peninsular Malaysia. A total of 35 isolates were classified under Rhizoctonia solani (multinucleate) and two isolates belonged to binucleate Rhizoctonia (BNR) according to the number of nuclei and morphological characteristics. Based on rDNA-ITS sequences and PCR profiling using AG group-specific primers, these isolates were identified as R. solani AG-1 IA (75.6%), AG-1 ID (10.8%), AG-2-2 IV (2.7%), AG-4 HG-I (5.4%), BNR AG-Fa (2.7%), and AG-A (2.7%). A specific primer of binucleate Rhizoctonia AG-Fa was designed and its specificity was evaluated by PCR. Further investigation using tef-1α gene confirmed the AG group identities for these isolates. Clustering analysis of molecular markers (OPA13 and OPE-6, 2080 iPBS, and 2249 iPBS and ISSR 3) supported the AG concept rather than geographical origin or plant host. Pathogenicity tests on the leaves of rice and corn showed that R. solani AG-1 IA rice isolates cause necrotic lesions greater than AG-1 IA corn isolates. Rhizoctonia solani AG-1 IA, AG-2-2IV, and AG-4 HG-I isolates cause necrotic lesions greater than BNR isolates on seedling of cabbage, cauliflower, and radish. To the best of our knowledge, this is the first study on morphology and molecular characterization of Rhizoctonia spp. isolated from various crops and regions in Malaysia.

“…The AG-1 IA sub-divide group is a pathogen that can spread through areal dispersal pathways. It causes leaf blight in many host species, especially sheath blight in rice, and brown spot on grass (Rosewich et al, 1999;Quadros et al, 2019). However, the AG-1-IC subgroup is soil-borne and causes damping-off disease in many host species.…”

Rhizoctonia solani is a soil- and seed-borne fungus belonging to class basidiomycete and capable of living free and as a saprophyte in the soil. It is divided into 14 anastomosis groups (AGs), which are incompatible with each other in terms of reproduction and proliferation. It has the potential to cause disease in various annual and perennial fruits, vegetables, and industrial and cereal crops. Plant diseases are mostly controlled by cultural methods; however, sometimes chemical control is also employed for this purpose. However, these control methods are mostly insufficient due to the soil-borne and saprophytic nature of the fungus. Therefore, researchers are working on other alternative methods. Biological control is one of the important ones among these methods. Antagonists used in biological control directly interact with R. solani through hyper-parasitism, antibiosis, or competition. Furthermore, antagonists trigger the defense reaction of host plants, which improves the control over the pathogens. The most important fungi species among these antagonists are; Trichoderma spp., Gliocladium spp., Verticillium biguttatum, and Stachybotrys elegans. The most important bacteria species used for the management of R. solani are; Fluoresent pseudomonas, Bacillus spp., Streptomyces spp., Pseudomonas fluorescens, and Erwinia spp. This review is focused on the biology, anastomosis groups, and biological control of R. solani. The antagonists used in biological control and studied mechanisms have been explained with examples. The review has been concluded with the latest developments in the literature.
