Role of Phenolics in Resistance to Rhizoctonia solani f. sp. sasakii Causing Banded Leaf and Sheath Blight of Maize

Defense reaction and biochemical interpretation of rice genotypes to sheath blight, Rhizoctonia solani Kuhn

“…The higher content of phenol in the resistant genotypes may be the possible reason for limiting the pathogenesis of the pathogen, thus reducing the disease, and vice versa in the susceptible genotypes, so that the disease was higher due to lower phenol content (Manjunatha et al 2021) [31] . Similar findings were reported by Dahima et al (2014) [9] and Anushree et al (2016) [3] , who found that total phenol accumulation was higher in inoculated rice genotypes compared to healthy ones, and it was significantly higher in blast-resistant genotypes.…”

Genetic diversity and resistance assessment among maize genotypes against banded leaf and sheath blight (caused by Rhizoctonia solani f. sp. sasakii) utilizing SSR markers

“…Moreover, the lack of resistance in maize germplasm further complicates this concerning scenario. Several conventional control measures have been explored such as mechanical stripping of lower leaf sheath (Batsa et al, 2004; Kaur et al, 2020; Mehra et al, 2012; Sharma & Hembram, 1989); botanical management using foliar application of garlic, neem and eucalyptus extracts (Kumar, Mehra, & Kumari, 2022e; Lal et al, 2016; Rajput et al, 2016); biological control using various biocontrol agents (Dahima et al, 2018; Lal et al, 2016); and integrated disease management combining fungicides, bioagents, and botanicals (Aggarwal et al, 2022; Debbrama & Rajesh, 2021; Kumar & Kaur, 2020; Sagar et al, 2020). However, long‐term viability of pathogen sclerotia in soil (Zachow et al, 2011; Zhao, Canaran, et al, 2006; Zhao, Zhang, et al, 2006) and inadequate implementation of agronomic practices (Raaijmakers et al, 2009; Savary et al, 2019) collectively leads to ineffectiveness of control measures against BLSB.…”
