“…The beneficial associations of some microbes can be exploited to enhance the availability of nutrients and useful minerals to improve plants’ health and immunity to induce resistance to root knot pathogens [ 114 , 179 ]. Some of these microbial isolates from rice rhizosphere are reported as biocontrol agents against root knot nematodes [ 180 ]. Panth et al [ 114 ] reported findings of important biocontrol agents such as Gliocladium catenulatum , which produce toxins effective against nematodes, Purpureocillium lilacirium as parasites on nematodes, and some beneficial Mycorrhizae spp.…”

Pea (Pisum sativum L.) is a grain legume widely cultivated in temperate climates. It is important in the race for food security owing to its multipurpose low-input requirement and environmental promoting traits. Pea is key in nitrogen fixation, biodiversity preservation, and nutritional functions as food and feed. Unfortunately, like most crops, pea production is constrained by several pests and diseases, of which rhizosphere disease dwellers are the most critical due to their long-term persistence in the soil and difficulty to manage. Understanding the rhizosphere environment can improve host plant root microbial association to increase yield stability and facilitate improved crop performance through breeding. Thus, the use of various germplasm and genomic resources combined with scientific collaborative efforts has contributed to improving pea resistance/cultivation against rhizospheric diseases. This improvement has been achieved through robust phenotyping, genotyping, agronomic practices, and resistance breeding. Nonetheless, resistance to rhizospheric diseases is still limited, while biological and chemical-based control strategies are unrealistic and unfavourable to the environment, respectively. Hence, there is a need to consistently scout for host plant resistance to resolve these bottlenecks. Herein, in view of these challenges, we reflect on pea breeding for resistance to diseases caused by rhizospheric pathogens, including fusarium wilt, root rots, nematode complex, and parasitic broomrape. Here, we will attempt to appraise and harmonise historical and contemporary knowledge that contributes to pea resistance breeding for soilborne disease management and discuss the way forward.

“…Rhizoctonia solani is widespread and poses a constant threat to rice farming in various rice‐growing nations, particularly in Southeast Asia, where it can reduce rice yield by up to 25% (Kumar et al, 2012; Taheri & Tarighi, 2011). In India, ShB causes 40–47% yield loss in rice crops and has emerged as one of the leading fungal diseases in the last two decades (Haque & Khan, 2021).…”

“…Rhizoctonia solani is reported to be antagonized by several BCAs, particularly Trichoderma species (Harman et al, 2004; Naeimi et al, 2010; Sallam et al, 2021). Other microbial antagonists, such as Bacillus subtilis (Kumar et al, 2012), Pseudomonas fluorescens (Yu et al, 2017) and P. putida (Haque & Khan, 2021) have also shown excellent biocontrol potential against R. solani . BCAs can be applied as seed priming (Seenivasan et al, 2012), soil (Khan et al, 2019) or foliar application (Yu et al, 2017), depending on the grower's/farmer's feasibility and crop type/stage.…”

A critical study of the available literature revealed that most of the investigations in this arena have been carried out on the different BCAs (Haque & Khan, 2021; Naeimi et al, 2010; Redda et al, 2018), but the effects of different modes and regimes of application have seldom been tested against R . solani in rice (Yu et al, 2017).…”

Relative effectiveness of seven different application methods of five native bacterial and fungal biocontrol agents (BCAs) and one fungicide (azoxystrobin) was evaluated against Rhizoctonia solani, under pot and field conditions on rice cultivar Pusa Sugandha‐5. Plants grown in pots infected with R. solani suffered a 30%–49% decrease in plant growth and yield of grain. However, treatment with BCAs reduced the adverse effect of the pathogen but significantly varied with the treatment schemes. Amongst the treatments, soil application (SA) at 20 + 40 days after planting (DAP) followed by foliar application (FA) at 60 DAP was recorded as most efficacious, and reduced the severity of disease by 42–68%, resulting in a 21–36% plant growth promotion and yield enhancement. Treatment comprising SA 20 + FA 40 DAP was next in effectiveness but statistically equal to seed priming (SP) + SA 40 DAP of treatment. Amongst the BCAs, Pseudomonas putida was shown to be the most efficient, trailed by Trichoderma harzianum, P. fluorescens, T. viride and Bacillus subtilis. Field trials under naturally infested fields have also validated the effectiveness of P. putida. The SA 20 + 40 + FA 60 DAP with P. putida and T. harzianum were found quite effective and decreased the disease severity and incidence (40–81%), and improved the grain yield (42–72%). Relatively lower ShB control was recorded with SA 20 + FA 60 DAP, however, it was statistically at par with SA 20 DAP treatment and equal to SA 20 + FA 40 DAP.
