“…have been found effective. During later stages of the crop two sprays of Ediphenphos or Kitazin or propiconazole (0.1%) or Carbendazim or tricyclazole (0.05%) (Palanna, 2021), first at the time of ear emergence and second after 10 days or an initial spray of 0.05% Carbendazim or tricyclazole followed by a spray of Mancozeb (0.2%) 10 days later are effective (Palanna, 2021). Two sprays of Saaf (0.2%) first at 50 per cent flowering and again 10 days later were also found effective in reducing the blast and increasing the yield (Ramappa et al, 2002).…”

Finger millet (Eleusine coracana) is one of the major staple food in India. the crop yield and its quality is affected by numerous factors including pre and post-harvest pathogens, poor storage conditions, improper irrigation practices and others. Among different phytopathogens which attack the Pyricularia grisea affects major yield loss in finger millet and many researchers developed potential management strategies to combat against target pathogen. This review deals with the overall information available for the utilization of bio-agents, against blast pathogen. Various researchers reported utilization of bio-agents is an effective management strategy against blast pathogen also economical and environmentally safe. In this review we made an attempt to present detailed overview potential utilization of bio-agents in supressing Pyricularia grisea.

“…Blast pathogen can infect all the stages of plant in both finger and foxtail millet, the young seedlings are more prone for the attack and showed burnt appearance in nursery under severe infection [9]. In finger millet, P. g r i s e a attacks at different growth stages of the crop and leads to formation of typical symptoms like leaf blast, neck blast and finger blast while in case of foxtail millet, P. setariae attacks the leaf lamina producing leaf blast symptoms [10][11][12][13].…”

Millets - Rediscover Ancient Grains

View full text Add to dashboard Cite

Millet crops are affected by various biotic and abiotic stresses. Among biotic stresses, blast disease caused by Pyricularia grisea (finger, pearl and proso millets) and Pyricularia setariae (foxtail millet) is the most devastating and widespread disease that causes substantial grain and forage yield losses and is a key constraint to pearl millet, finger millet and foxtail millet production in most of finger millet growing areas, and recently, it is also reported in barnyard millet in few locations. This book chapter emphasizes mainly on occurrence, distribution, symptoms, yield loss, etiology, genetic diversity, mode of spread of the pathogen and survival and integrated disease management approaches for mitigating of disease. This information will be highly helpful for better understanding of the disease. Further, it will be useful to enhance production and productivity of millets and to reinforce the food and nutritional security in the developing countries of Asia and Africa continents where the millets are mainly grown as staple food crops.

“…The blast disease, which is incited by Magnoporthe spp., is a most destructive biotic constraint affecting the millets, including rice. It affects in all the growth stages of plants especially different aerial parts of the plants, from the seedling stage to seed setting in finger millet, causing neck and/or finger blast, while it is restricted to the leaf only in the case of pearl millet, foxtail millet, and barnyard millet ( Palanna et al., 2021 ; Rajashekara et al., 2021 ). Blast is found in most of the regions where millets are grown.…”

Blast pathogen, Magnaporthe spp., that infects ancient millet crops such pearl millet, finger millet, foxtail millet, barnyard millet, and rice was isolated from different locations of blast hotspots in India using single spore isolation technique and 136 pure isolates were established. Numerous growth characteristics were captured via morphogenesis analysis. Among the 10 investigated virulent genes, we could amplify MPS1 (TTK Protein Kinase) and Mlc (Myosin Regulatory Light Chain edc4) in majority of tested isolates, regardless of the crop and region where they were collected, indicating that these may be crucial for their virulence. Additionally, among the four avirulence (Avr) genes studied, Avr-Pizt had the highest frequency of occurrence, followed by Avr-Pia. It is noteworthy to mention that Avr-Pik was present in the least number of isolates (9) and was completely absent from the blast isolates from finger millet, foxtail millet, and barnyard millet. A comparison at the molecular level between virulent and avirulent isolates indicated observably large variation both across (44%) and within (56%) them. The 136 Magnaporthe spp isolates were divided into four groups using molecular markers. Regardless of their geographic distribution, host plants, or tissues affected, the data indicate that the prevalence of numerous pathotypes and virulence factors at the field level, which may lead to a high degree of pathogenic variation. This research could be used for the strategic deployment of resistant genes to develop blast disease-resistant cultivars in rice, pearl millet, finger millet, foxtail millet, and barnyard millet.
