“…Gopika and Jagadeeshwar [14] also reported that spraying with propiconazole (100 ppm) prominently reduced the disease (1.2 disease index) over the other treatments. Pramesh et al [5] tested new combination of chemical Captan 70% + Hexaconazole 5%) with dosage of 750 g/ha which was showed promising effects in controlling stem rot disease. Gowdar et al [3] conducted field efficacy studies with different chemicals against rice stem rot.…”

“…Although cultural, physical control methods are available but they are in limited use especially under epidemic conditions. Chemical and bio control methods are found to be reliable and effective [5,6]. In the present study an investigation has been conducted to evaluate the comparative efficacy of different chemical fungicides and antagonistic bacteria against rice stem rot disease.…”

Rice stem rot disease in paddy cultivation leads to reduction of yield. Management of this disease is difficult as it is soil borne. In the present study, field trials were conducted during Rabi 2016-17 and early Kharif 2017-18 to assess the effectiveness of twelve fungicides and four rhizosphere bacterial antagonistic isolates (RRB-1 to RRB-4) against rice stem rot disease. Disease incidence was recorded from the date of initial incidence of the disease i.e., once in 15 days from maximum tillering to panicle emergence. Pooled analysis reveals that Hexaconazole recorded lowest per cent disease index (32.22) with highest grain yield and straw yield of 7.43 t/ha and 7.22 t/ha respectively, followed by Difenoconazole with grain yield and straw yield of 7.29 t/ha and 6.88 t/ha respectively. On the other hand, bacterial antagonists using root dipping and foliar spray with RRB-4 showed less PDI of 32.92 with grain yield of 6.97 t/ha and straw yield of 6.61 t/ha. With this study, hexaconazole (0.2%) and bacterial antagonists RRB-4 using root dipping and foliar spray (105 to 106 CFU/ml) can be effectively managed the rice stem rot.

“…The chemical control being the major option for disease management and only a handful of fungicides are available for the management of rice sheath blight 5 . For the management of sheath blight disease systemic fungicides like carbendazim, mancozeb, captafol, benomyl and validamycin have been found effective 6 , 7 . However, indiscriminate use of these fungicides could result to development of resistance in the pathogen 8 .…”

Rice (Oryza sativa) being among the most important food crops in the world is also susceptible to various bacterial and fungal diseases that are the major stumbling blocks in the way of increased production and productivity. The bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae and the sheath blight disease caused by Rhizoctonia solani are among the most devastating diseases of the rice crop. In spite of the availability of array of chemical control, there are chances of development of resistance. Thus, there is a need for the nanotechnological intervention for management of disease in the form of copper and silver nano-composites. The copper (CuNPs) and silver nanoparticles (AgNPs) were synthesized using green route and characterized using different high throughput techniques, i.e., UV–Vis, FT-IR, DLS, XRD, FE-SEM, TEM. The particle size and zeta potential of synthesized CuNPs and AgNPs were found 273 nm and − 24.2 mV; 95.19 nm and − 25.5 mV respectively. The nanocomposite of CuNPs and AgNPs were prepared having particle size in the range of 375–306 nm with improved stability (zeta potential − 54.7 to − 39.4 mV). The copper and silver nanoparticle composites evaluated against Xanthomonas oryzae pv. oryzae and Rhizoctonia solani were found to have higher antibacterial (inhibition zone 13 mm) and antifungal activities (77%) compared to only the copper nanoparticle (8 mm; 62% respectively). Net house trials of nano-composite formulations against the bacterial blight of rice also corroborated the potential of nanocomposite formulation. In silico studies were carried out selecting two disease-causing proteins, peptide deformylase (Xanthomonas oryzae) and pectate lyase (Rhizoctonia solani) to perform the molecular docking. Interaction studies indicatedthat both of these proteins generated better complex with CuNPs than AgNPs. The study suggested that the copper and silver nano-composites could be used for developing formulations to control these devastating rice diseases.

“…These bioagents create less favourable conditions for the growth and development of the soilborne pathogen S. oryzae, which causes stem rot disease in rice, either directly or indirectly by manipulating the soil nutrients and chemical composition, and such soils are called suppressive soils [21]. Stem rot disease of rice is generally managed by the application of chemical fungicides, and these practices are less preferred due to the awareness of the residual effects of fungicides in the grains, damage to human and animal health, and pollution of the environment [22]. Through their combined effects on soil properties and their direct antagonistic activity against stem rot pathogens, these native bioagents create a synergistic effect that ultimately leads to a reduction in the occurrence of stem rot disease in rice.…”

Soil is a crucial component for plant growth, as it provides water, nutrients, and mechanical support. Various factors, such as crop cultivation, microflora, nutrient addition, and water availability, significantly affect soil properties. Maintaining soil health is important, and one approach is the introduction of native organisms with multifaceted activities. In this study, the effects of four native microbes (Trichoderma asperellum strain TAIK 1, Bacillus cabrialesii strain BIK3, Pseudomonas putida strain PIK1, and Pseudomonas otitidis strain POPS1) and their consortia on soil health, plant growth, and the incidence of stem rot disease caused by Sclerotium oryzae in rice are evaluated. Upon bioagent treatment of soil through seed treatment or soil application, variations in chemical properties of the soil were observed, viz., pH, Electrical Conductivity (EC), Organic Carbon (OC), available Soil Nitrogen (SN), Soil Phosphorus (SP), Soil Potassium (SK), and soil enzymes (urease, acid and alkaline phosphatase, dehydrogenase), compared to untreated soils. The treated seeds with the consortia of four native bioagents resulted in a significant increase in plant height (39.16%), number of panicles (30.29%), and average grain yield (41.36%) over control plants. Under controlled conditions, the bioagents-treated plants showed a 69.37% reduction in stem rot disease. The findings of this study indicate a positive correlation between soil properties and plant growth as well as a highly negative association with stem rot disease severity. The results suggest that using native bioagents as a management strategy can control stem rot disease and enhance crop productivity while reducing reliance on chemical interventions. These findings provide valuable insights for the development of sustainable agricultural practices that promote soil health, plant growth, and disease management.
