“…As regards ICBR (Incremental Cost: Benefit Ratio) in Table 2 different treatments, the maximum ICBR ratio (1:20.68) was recorded in treatment consisting (T4): Deep summer ploughing with mould board plough+Seed treatment with Tebuconazole 1.5 g/kg seeds+Soil application of Trichoderma @ 4 kg/ha enriched in 250 kg FYM/ha at 35 and 80 DAS followed by treatment (T1). This finding collaborates with the finding of earlier workers Kumhar et al (2018) reported that treatment module consisting of seed treatment with Tebuconazole 2 DS @ 1.5 g kg/seed+furrow application of T. viride @ 4.0 kg enriched with 50 kg FYM ha -1 + broadcasting of T. viride @ 4.0 kg enriched with 50 kg FYM ha -1 at 40 DAS+two foliar sprays of Tebuconazole 25.9% EC @ 1.0 ml starting from initiation of diseases and second spray at 15 days intervals was found most effective and economically beneficial treatment module in controlling of collar rot disease of groundnut and Smith et al (2000) reported that increased groundnut pod yield and higher net return was also recorded after seed treatment and fungicidal spray in groundnut as compared to the untreated control. Similarly higher economic returns and benefit-cost has shown some benefits in managing the collar rot of (Gangwar et al, 2014;Rawal et al, 2013;Sharma et al, 2017).…”

Background: Groundnut is an economically important edible oilseed crop. Groundnut suffers from seed, soil and foliar diseases. Among the groundnut diseases, collar rot is one of the economically important diseases. Collar rot is damaged regularly due to its seed and soil-borne nature. This disease is prevalent in almost all groundnut-growing states. Collar rot disease of groundnut is one of the most serious, destructive diseases and yield losses range from 13 to 52% and can be as high as 93.6% in some areas. Being mainly a soil-inhabiting pathogen, many environmental and soil factors are responsible for disease development. Methods: Field experiment was conducted for four years to find out effective control of collar rot of groundnut. Eight treatments including fungicides/bio agents along with control were laid in randomized block design with three replications. Efficacy of deep summer ploughing with mould board plough+Seed treatment with Tebuconazole followed by PGPR+Soil application of Trichoderma enriched in 250 kg FYM/ha at 35 and 80 DAS along with farmer practices as well as control was tested at ARS, Bikaner in RBD design during kharif season from 2017 to 2020 for management of collar rot diseases of groundnut. Result: The result of experiment revealed that deep summer ploughing with mould board plough+Soil application of Trichoderma @ 4 kg/ ha enriched in 250 kg FYM/ha+Seed treatment with Tebuconazole 2 DS @ 1.5 g/kg of seed followed by seed treatment with PGPR @ 625 g/ha of seed+Soil application of Trichoderma @ 4 kg/ha enriched in 250 kg FYM/ha at 35 and 80 DAS (T4) gave maximum germination (93.00%), minimum collar rot incidence (6.17%) and highest pod yield (4066.3 kg/ha) followed by deep summer ploughing with mould board plough+Seed treatment with Tebuconazole 2DS 1.5g/kg seed followed by PGPR @ 625 g/ha of seed+Soil application of Trichoderma @ 4 kg/ ha enriched in 250 kg FYM/ha at 35 and 80 DAS (T1) where germination (89.30%), collar rot (7.04%) and with pod yield (3661.9 kg/ha). All the treatment significantly were superior as compared to control, where minimum germination (82.00), maximum collar rot incidence (15.59 %) and minimum pod yield (2125.1 kg/ha) were recorded. As regard to ICBR, in different treatments, maximum ICBR ratio (1:20.68) was recorded in treatment consisting (T4): Deep summer ploughing with mould board plough+Seed treatment with Tebuconazole 1.5 g/kg seeds+Soil application of Trichoderma @ 4 kg/ha enriched in 250 kg FYM/ha at 35 and 80 DAS followed by treatment (T1).

“…Brenenman et al [47] tested the effect of propiconazole and reported that the fungicide could be used effectively for the management of stem rot of groundnut. The present result are in agreement with the results obtained by Adiver and Anahosur [48], who reported that triazole group of fungicides i.e., tebuconazole and cyperconazole were effective against colonization of Sclerotium rolfsii. The present result corroborated the finding of Bowen et al [49] who reported that incidence of southern stem rot (S. rolfsii) was inversely related to number of tebuconazole applications, while yield was directly related to number of tebuconazole applications.…”

Groundnut regarded as “king of oil seed crops” is an economic important food legume and edible oilseed crop in India, which severely suffers from soil borne diseases of groundnut, collar rot (Aspergillus niger), stem rot (Sclerotium rolfsii) and root rot (Rhizoctonia solani) causing major havoc causes significant economic losses. The field experiments were conducted to find out the efficacy of Tebuconazole 6% FS as a seed treatment fungicide against collar rot, stem rot and root rot diseases complex in ground nut during Rabi 2014-15 and Rabi 2015-16. The treatment Tebuconazole 6% FS @ 4.0 ml/10 kg and Tebuconazole 6% FS @ 5.0 ml/10 kg of seeds were found be the best treatments for seed germination, root and shoot length in during both the seasons.During first season, Tebuconazole 6% FS @ 5.0 ml/10 kg of seeds and Tebuconazole 6% FS @ 4.0 ml/10 kg of seeds were recorded 1.77 and 2.14 per cent collar rot incidence, 3.07 and 4.23 per cent stem rot disease incidence and 4.93 and 5.05 per cent root rot disease incidence, respectively. Similarly during second season, Tebuconazole 6% FS @ 5.0 ml/10 kg of seeds and Tebuconazole 6% FS @ 4.0 ml/10 kg of seeds were recorded 1.89 and 2.06 per cent collar rot incidence, 4.05 and 5.13 per cent stem rot incidence and 5.74 and 5.94 per cent root rot incidence, respectively. The highest pod yield was obtained from seed treatment with Tebuconazole 6% FS @ 5.0 ml/10 kg of seeds i.e. 20.22 q/ha and 20.10 q/ha during first and second season, respectively and Tebuconazole 6% FS @ 4.0 ml/10 kg of seeds recorded 20.12 q/ha and 20.00 q/ha of pod yield during first and second season, respectively.

“…The microbial consortia could potentially proliferate in the soil and survive throughout the cropping season and protect the crop from harmful pathogenic infection [19,20]. Earlier workers have proven that the native isolate of bioagents could reduce the disease intensity of LLS and rust [21,22]. The biocontrol agents like Trichoderma and Pseudomonas produce antibiotics, iron-chelating agents, cell wall degrading enzymes and secondary metabolites that act on pathogens to suppress the pathogens' growth effectively [23,24].…”

This study investigated the efficacy of various biocontrol-based formulations against late leaf spot (LLS) (Phaeoisariopsis personata) and rust (Puccinia arachidis) in groundnut. Pot culture and field experiments were conducted during the Kharif season (June-September) of 2022. Disease incidence of both late leaf spot and rust was significantly lower in groundnut plants treated with a combination of biocontrol-based formulations compared to control. The most effective eco-friendly treatment included a combination of Trichoderma asperellum, Pseudomonas fluorescens, fortified lignite fly ash and Annamalai mixture. This combination significantly reduced lesion frequency and Percent Disease Index (PDI) for both diseases at 50, 70 and 90 DAS, compared to other treatments. The combination of biocontrol-based formulations also significantly increased the pod yield. Furthermore, the same treatment increased the induction of defense enzymes peroxidase (2.22 fold), polyphenol oxidase (1.28 fold) and phenylalanine ammonia-lyase (6.25 fold). While Carbendazim effectively reduced disease incidence, it was surpassed by the biocontrol-based module in terms of both disease control and yield. These findings suggest that biocontrol-based formulations can be a sustainable approach for managing LLS and rust diseases in groundnut cultivation.
