Increasing concerns about chemical fungicides require sustainable alternatives for crop protection. Microbe-mediated synthesis of metal nanoparticles offers a sustainable, eco-friendly and highly effective strategy for plant disease management. This study investigates the mycosynthesis of zinc oxide nanoparticles (ZnO NPs) using the culture filtrat...

Pyricularia oryzae is the major pathogen affecting primarily rice and many other graminaceous plants. Cultural, morphological and molecular identification was performed using the internal transcribed spacer (ITS). The pathogen was managed in vitro and in vivo using fungicides. Fungal growth was very slow on potato dextrose agar medium (PDA). Maximu...

Sunflower (Helianthus annuus L.) is a globally significant oilseed crop, valued for its oil-rich seeds and versatility in various industries. However, sunflower cultivation faces persistent threats from a range of diseases and insect pests that can severely impact yield and quality. Sunflower crops are susceptible to several fungal, bacterial, and...

Alternaria blight, rapeseed-mustard, resistance, genotypes, PDI, AUDPC Alternaria blight is one of the major biotic stresses causing heavy yield losses to the mustard crop, globally. An experiment was conducted to evaluate some rapeseed-mustard genotypes for Alternaria blight under field conditions during Rabi 2022-23 and 2023-24. The observation o...

White rust disease caused by a biotrophic oomycete Albugo candida is one of the most serious impediments in realizing the production potential of Brassica juncea. Due to the obligate nature of the pathogen, R-gene-based resistance is unstable as the newer virulent races emerge quickly. For this, a deep understanding of the molecular basis of resist...

Background White rust disease caused by the biotrophic oomycete Albugo candida is one of the most serious impediments in realizing the production potential of Brassica juncea. Moreover, due to the obligate nature of the pathogen, R-gene-based resistance is unstable as the newer virulent races emerge quickly. Therefore, a deeper understanding of the...

Rice (Oryza sativa L.) is the most widely produced food crop in the world, providing sustenance for almost half of the world's population. The crop subjected to various biotic and abiotic stresses as a result of varying climatic and ecological conditions. Several microorganisms are considered to be the main cause of grain discolouration, which has...

Fungicidal resistance in plant pathogens and its remedial measures Fungicides are substances which kills the fungal spores or mycelium and prevents the fungal growth. Fungicidal resistance refers to an acquired, heritable reduction in sensitivity of a fungus to a specific anti-fungal agent or fungicide. Fungi are constantly changing like other orga...

During times countless NPR 1 dependant pathways have been discovered but much of it is left to be answered, due to the relationship that exists between NPR 1, their interacting partners and paralogs. The Pathogenesis Related (PR) genes, as well as the Non-expressor of Pathogenesis Related 1 (NPR 1) gene, play an important part in the plant defence...

Rice production and productivity is affected due to several biotic and abiotic stresses. Among the major biotic stresses blast disease of rice caused by Pyricularia oryzae has the potential to causes annually yield loss as high as 70-80% when pre-disposing factors favour epidemic development. The use of resistant cultivars is the most cost-effectiv...

Brinjal production and productivity is affected due various biotic and abiotic factors. Among the biotic factors Sclerotiona blight (Sclerotinia sclerotiorum) is one of the destructive disease. It causes huge loss in economic yield as well as reduction in the quality of fruit. Among different control measures strategy use of resistant variety is th...
