In this study, at least 24 RNA-Seq datasets related to blast disease infection in rice plants have been obtained from databases. Among them, four microarray datasets obtained from blast-infected leaf samples in Indica rice varieties, including GSE122258, GSE126961, GSE78266 and GSE39635 were selected for further in silico analysis.

Balancing the yield, quality and resistance to disease is a daunting challenge in crop breeding due to the negative relationship among these traits. Large-scale genomic landscape analysis of germplasm resources is considered to be an efficient approach to dissect the genetic basis of the complex traits.

Nitrogen fertilization is known to increase disease susceptibility, a phenomenon called Nitrogen-Induced Susceptibility (NIS). In rice, this phenomenon has been observed in infections with the blast fungus Magnaporthe oryzae.

The genus Pyricularia (anamorph)/Magnaporthe (teleomorph) causes blast disease on a broad range of plants including rice, foxtail millet and other species of the family Poaceae. The infected leaves of foxtail millet with typical spindle shaped lesions of light tan in colour, dusty gray appearance with necrotic borders were collected from various regions of Tamil Nadu during 2017 and 2018 and the pathogen was isolated from the samples. The collected isolates were named as TNFxM1 to TNFxM32.

A major issue in rice production is the control of Magnaporthe oryzae, the causal agent of rice blast. K 343 being a well adapted variety in the hill zone of Jammu and Kashmir region is susceptible to blast. Present study was undertaken to introgress the broad spectrum resistance gene Pi9 through marker assisted backcross breeding in order to avoid the losses due to this fungus.

Rice (Oryza sativa) occupies a prime position in the family Poaceae and it is the highly consumable crop of almost half of the world's population. Among the various diseases affecting rice, blast incited by Magnaporthe oryzae is the one of the ubiquitous and economically important disease which affects almost all the stages of crop and cause yield loss upto 50%. In the present study, survey was carried out in Nilgiri and Madurai districts of Tamil Nadu for the collection of blast isolates. The blast disease incidence ranged from 8.8 to 42.4 per cent in various rice cultivars.

The study was conducted in Palamu district of Jharkhand to know the socioeconomic status of farmers. They were categorized in three groups i.e. small ,medium and large farmers which were differ from each other with regard to socio –economic factors and found that 54 per cent rice growers has medium level of knowledge .

A survey was conducted on Swarna cultivar (MTU 7029) of rice during Kharif 2013, 2014, 2015 and 2016 at Nadia district of West Bengal to record the fungal disease and their respective yield loss. Ten diseases (Leaf blast, Sheath blight, Sheath rot, Brown spot, Brown Leaf Spots caused by Curvularia lunata, Stackburn disease, Leaf spot caused by Nigrospora oryzae, Stem rot, Rotting by Choanephora cucurbitarum and False smut) were based on visual observation on Swarna rice cultivar and yield loss due to respective disease was calculated by measuring test weight (gm) of rice grains.

Rice is staple food for more than half of the world’s population. The fast growth of the world population demands an increase of 26 % in rice production to fulfill the requirement. The rice blast caused by Magnaporthe oryzae is considered to be the most significant and potentially damaging rice disease in the world and has been responsible for 35 to 50 % global loss in rice yield causing serious constraint in global food supply.

The study was carried out to evaluate the efficacy of fungicides and bio-agents against the blast and brown spot disease in basmati rice under in vitro condition. All three fungicides (Tricyclazole75% WP, Propiconazole 25% EC and hexaconazole 5% EC) were found quite effective against the blast and brown spot disease of basmati rice.

The disease cycle of rice blast involves three distinct phases: infection (germination of conidia), colonisation of mycelium, and sporulation (7). The present study has analysed and identification of rice blast i.e. incidence and intensity.

The pathogen is adaptable to adverse environmental conditions of widely fluctuating temperatures and relative humidity. It appears in irrigated low land or rain fed upland rice as well as in submerged or deep water rice. Rice was important crop in both Andhra Pradesh and Telangana states and losses due disease was also more. Keeping this in view we are conducting survey in both the states to identify the severity of disease.

Rice blast caused by Pyricularia grisea (Cooke) Sacc. became one of the most important disease in rice growing areas of Telangana State because of its wide distribution and destructiveness under favourable conditions. However, sometimes resistant varieties may become ineffective due to evolutionary changes in the pathogen population. Keeping in view the importance of disease, studies were conducted on cultural and morphological variability of P. grisea isolates.

Rice (Oryza sativa L.) is an important cereal crop and prone to many diseases out ofwhich, rice blast caused by Pyricularia grisea is of significant economic importance due to its destructive nature leading to serious yield loss. Blast infected leaves of rice, Panicum grass and finger millet were collected from different fields of OUAT farm, Bhubaneswar.

Quantitative trait locus (QTL) mapping is a highly effective approach for studying genetically complex forms of plant disease resistance. With QTL mapping, the roles of specific resistance loci can be described, race-specificity of partial resistance genes can be assessed and interactions between resistance genes, plant development and the environment can be analysed (Young, 1996). DNA markers tightly linked to quantitative resistance loci (QRLs) controlling QDR can be used for marker-assisted selection (MAS) to incorporate these valuable traits.

Temperature rise due to climate change is expected to change pathogenicity of the pathogen. Temperature has a significant influence on growth and sporulation of rice leaf blast pathogen (M. oryzae). Both growth and sporulation were increased up to a temperature (27°C) and declined further in response to increased or decreased with temperature (32°C and 22°C). Various components of rice blast infection observed maximum at 27°C (optimal temperature) compared to suboptimal (22°C) and supraoptimal (32°C) i.e.

A field experiment was conducted at Agricultural College Farm, Bapatla to test the efficacy of some recommended insecticides and fungicides as a tank mix application. Two insecticidal treatments (chlorantraniliprole @ 0.3 ml l-1 and chlorpyriphos @ 2.5 ml l-1 ) and two fungicidal treatments (tricyclazole @ 0.6 g l-1 and isoprothiolane @ 1.5 ml l-1 ) with an untreated control were replicated thrice in a simple randomized block design. The results showed that all the insecticide and fungicide treatments alone and in combination were found superior over untreated check.
