Tomato is an important nutritional vegetable crop and its nutrient contents are affected by both biotic and abiotic stresses. The main objective of this study was to determine the effect of seed biopriming with Trichoderma pseudokoningii BHUR2 and vermiwash treatment on nutrient content of tomato and defense response against Sclerotium rolfsii unde...

To provide food security with quality crops for exponentially growing population brought intense pressure on the limited land and natural resources among developing countries. Abiotic stresses such as continuously rising temperature as consequences of global warming is adding pressure to existing problems by adversely affecting crop productivity th...

Microbial volatile organic compounds (mVOCs) have great potential in plant ecophysiology, yet the role of belowground VOCs in plant stress management remains largely obscure. Analysis of biocontrol producing VOCs into the soil allow detailed insight into their interaction with soil borne pathogens for plant disease management. A root interaction tr...

Endophytic microbes intricately modulate host defense pathways upon challenge with any form of environmental stress. In the current study, endophytic Alcaligenes faecalis treated okra plants were found to exhibit significant resistance to cell-lysis and disintegration upon infection with Sclerotium rolfsii. Apart from the morphological amendments,...

Salt tolerant bacteria can be helpful in improving a plant’s tolerance to salinity. Although plant–bacteria interactions in response to salt stress have been characterized, the precise molecular mechanisms by which bacterial inoculation alleviates salt stress in plants are still poorly explored. In the present study, we aimed to determine the role...

Seed biopriming is an emerging technique to enhance seed germination under stress conditions. An integrated approach of tomato seed biopriming with ascorbic acid, Trichoderma asperellum BHU P-1 and Ochrobactrum sp. BHU PB-1 was applied to observe the response against wilt pathogen of tomato Fusarium oxysporum f. sp. lycopersici (FOL). Tomato seeds...

Fusarium oxysporum is one of the most devastating fungal pathogen, worldwide having wide host range, infecting large number of monocot and dicot. In the present study, scientometrics approach has been used to summarise all study on F. oxysporum in a single article. We collected a total 5358 reports from Web of Science (WoS) since 2009 to till date...

Seed priming enables seed hydration, thereby activating its metabolism without substantial germination. It also assists in rapid germination as well as enhances resistance to both biotic and abiotic stresses. Soilborne pathogens such as Sclerotium rolfsii, Sclerotinia sclerotiorum, and Rhizoctonia possess major threat to crop production on a global...

An incessant increase in global population along with a continuous augmentation in abiotic stress conditions, such as temperature, pH, salinity, etc., and limitation of natural resources has posed a serious threat to developing nations in terms of food security and enhanced nutritional value of the yield. Substantial crop losses in both qualitative...

Soil borne phytopathogens are one of the major challenges in crop production which lowers the plant yield and quality of the produce.

Sclerotium rolfsii Sacc. is the most destructive soilborne fungal pathogen causing collar rot disease in tomato crop. For management of collar rot disease several chemical fungicides are using that cause hazardous impacts on agroecosystem as well as human health. In the present study, Trichoderma spp. are used for management of collar rot disease i...

Fusarium wilt is one of the major diseases of tomato causing extensive loss of production. Exploration of agriculturally important microbes (AIMs) for management of the tomato wilt is an ecofriendly and cost effective approach. In the present study, a total 30 Trichoderma and 30 bacterial isolates were screened in the laboratory for their biocontro...

Rhizobia are group of organism, known globally for their nitrogen-fixing ability. In addition to nitrogen fixation, they significantly contribute to plant growth promotion and disease control. Rhizobial aptness for plant growth promotion and antagonism against a wide range of pathogens is due to its ability to produce a wide range of secondary meta...

Stalk rot sorghum caused by Dickeya dadantii (syn. Erwinia chrysanthemi) is a devastating sorghum disease and is highly detrimental to sorghum cultivation in tarai region of India. The bacterium disrupts and disintegrates vascular bundles of sorghum stem manifesting slimy soft rot symptom. In vitro studies on bioagents and chemicals revealed that a...

The concept of nanotechnology was first given by American theoretical physicist Richard Feynman, 1959 in his classic talk’There’s Plenty of Room at the Bottom’(Feynman, 1960). The term’nanotechnology’was first coined by Norio Taniguchi (Taniguchi, 1974). It is the science of manipulation of matter on an atomic, molecular and supermolecular level. T...

Stalk rot caused by Erwinia chrysanthemi is one of the most destructive diseases of sorghum crop. The bacterium was isolated from infected sorghum plants collected from livestock research centre, G.B. Pant University of Agriculture and Technology, Pantnagar, India. Biochemical, physiological and morphological characterization of the isolate was don...

In past few decades, the introduction of plastic was changed in the scenario of packing industry in terms of easy, fast and safe movement of goods, but also led to a new big problem for our environment. The current consumption of plastics at the global level is more than 220 million tonnes. They are quite difficult to recycle or reuse and non-biode...

Stalk rot caused by Erwinia chrysanthemi (Ech) is one of the most destructive diseases of sorghum crop. The bacterium was isolated from infected sorghum plants collected from livestock research centre, G.B. Pant University of Agriculture and Technology, Pantnagar, India. Evaluation of inoculation methods viz. leaf whorl inoculation, stem injection...
