In this study, we isolated rice endophytic bacteria and selected strains that have antagonistic activity against Dz for application in controlling the foot rot disease. The endophytic strain VY81 isolated from stem of a rice plant with foot rot disease was studied in details since it had prominent antagonistic activity against Dz.

We have previously developed a rice-based oral vaccine against cholera diarrhea, MucoRice-CTB. Using Agrobacterium-mediated co-transformation, we produced the selection marker–free MucoRice-CTB line 51A, which has three copies of the cholera toxin B subunit (CTB) gene and two copies of an RNAi cassette inserted into the rice genome.

Maize is considered to be the third most important cereal after rice and wheat in India. It is being cultivated worldwide in a wider range of environmental conditions, because of its greater adaptability. It is known to be affected by more than 62 diseases. Among them, turcicum leaf blight caused by Exserohilum turcicum (Pass.) Leonard and Suggs is of significant importance as it drastically reduces the yield by reducing photosynthetic activity of the plant.

Brown plant hopper (BPH), Nilaparvata lugens Stal is one of the most serious rice pest in India. Growing of resistance varieties is the most effective and environment-friendly strategy for protecting the crop from BPH. In the present study we evaluated the forty entries of plant hopper screening trial against BPH under glass house condition. The trial material was received from All India Coordinated Rice Improvement Programme (AICRIP) DRR, Hyderabad during kharif 2011.

The bacterial leaf blight of rice caused by Xanthomonas oryazae pv. oryzae is the disease of great economics importance in India especially in Bihar. Management of BLB disease can play a vital role in management of rice disease. In the present investigation evolution of different plant extract (botanical) and new chemical on growth of bacteria by poison food technique and sowing by best botanical and new chemical were conducted and antagonistic activity were tested.

Rice (Oryza sativa) is the most important staple food crop in India. It ranks second in worldwide production. An anatomical and physiological character of surface of the rice leaf renders a sustainable environment for diversity of phylloplane microorganisms that showed antagonism against rice pathogens. The objective of this present study was to identify and characterize the bacterial population in the phylloplane of rice at different critical stages.

In vitro evaluation of twelve phytoextracts (aqueous and methanolic extract) of locally available plants having antimicrobial properties were done against Rhizoctonia solani, Kuhn by sequentially highering the concentration of the extracts i.e. at 1%,2.5%, 5% and 10%. The poisoned food technique employed for the purpose.

Evaluation of resistance in some rice genotypes against brown Planthopper, Nilaparvata lugens (Stal)
Studies were carried out under glass house conditions to study the evaluation of resistance in some rice genotypes against Brown plant hopper, Nilaparvata lugens. Among the rice genotypes tested against N. lugens (Stal), Ptb 33 (the resistant check) lowest mean damage rating (1.00), while genotypes, PTB 41 exhibited a damage score ranging from (1.00-1.67), when compared to T(N)1 (9.00).The genotypes viz., Co 43, ADT 36, Columbia, Swarna, SR 26B were moderately resistant with damage rating of (3.00-3.67) and the remaining genotypes were moderately susceptible or highly susceptible.

Most of the rice diseases are transmitted by seeds which are the important limiting factor getting good quality seeds and good yield. Stored and freshly harvested rice seed of different varieties were collected from Agricultural farm of Orissa University of Agriculture and Technology, Bhubaneswar, Odisha to study the association of different fungal pathogens. The seeds were graded on the basis of intensity of discoloration.
