Xanthomonas oryzae pv. oryzae (Xoo) causes severe bacterial leaf blight (BLB) disease to many Vietnamese major rice cultivars, including the TBR225. OsSWEET13 belongs to group III of the OsSWEET gene family encoding sugar transport proteins, which is considered one of the “susceptibility” genes (S genes) necessary for BLB disease.

In Asia, rice is the most important, widely consumed staple food for a large part of the world's human population. Bacterial leaf blight (BB), caused by the bacterium, Xanthomonas oryzae pv. oryzae (Xoo) is one of the major disease affecting Basmati rice production in India. CSR-30 is a very popular high yielding, salt tolerant Basmati variety widely grown in Haryana, India but highly susceptible to BB.

This study aims to find antagonistic bacteria that are able to provide the highest resistance to the growth of pathogenic Xoo bacteria in rice plants. Antagonistic bacteria were isolated from the leaves and roots of rice plants through surface sterilization and serial dilution. Obtained 53 bacterial isolates consisting of 20 bacterial isolates from leaves and 33 bacterial isolates from roots tested hypersensitive to tobacco plants for filtering potential non-pathogenic bacteria.

Cotton is one of the principal commercial crop and it is the back bone of national economy of our country. Cotton remains the most miraculous fiber and is still nature’s wonder fiber. Cotton is grown all around the globe, and is traded internationally as well. The production is influenced by the repeated out breaks of pest and diseases and these are the major factors responsible for lower yield of cotton in India.

The present study was conducted at the experimental farm of ICAR Research Complex for Eastern Region, Patna, India in Kharif season 2016 with an objective to identify sheath blight and bacterial leaf blight disease resistance rice genotypes under submergence condition in middle Indo Gangetic Plain. The disease incidence was observed at maturity stages during Kharif season 2016. The incidence of sheath blight and bacterial leaf blight of paddy ranged from 18.6 to 39.0% and 15.3 to 34.0%, respectively.

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.

Sunflower is an important major oilseed crop ranks next to groundnut and soybean at global level. It belongs to the family Asteraceae and mostly infected by several fungal, bacterial and viral diseases among which leaf spot and blight caused by Alternaria helianthi was considered as one of the most destructive diseases in the sunflower growing areas. An experiment was studied to determine the disease incidence and intensity of the disease in both Kharif and Rabi season (2018-19) by observing the plant raised in field.

Bacterial leaf blight of rice, caused by Xanthomonas oryzae pv. oryzae is not only a problem in India but also worldwide. Management using chemicals is undoubtedly quick in action, restricting the severity and spread of the disease. Both in vitro and in vivo studies were conducted to investigate the inhibitory potential of different chemicals against the bacterial pathogen.

One hundred rice genotypes were analyzed to evaluate the genetic polymorphism and identification of resistant lines to bacterial leaf blight (BLB) disease caused by Xanthomonas oryzae pv. oryzae using simple sequences repeat (SSR) markers. A total of 38 alleles were detected by seven polymorphic markers showing highly polymorphic across all genotypes with an average of 5.42 alleles per polymorphic marker. The marker RM-21, RM-122 and RM-224 produced maximum 6 alleles.

The major diseases affecting chilli productions are Anthracnose, Phytopthora, Leaf blight, Fusarium wilt, bacterial wilt, damping-off and root rot etc. Among these, Fusarium wilt caused by the Fusarium oxysporum has emerged as a serious problem in recent year. In this investigation, to study the mycorrhizal population dynamics and wilt intensity in chilli growing areas of state, the survey was undertaken during crop season 2017-18 in Hisar, Fatehabad and Mohindergarh districts.

Rice crop accounts for nearly a third of the total area under food grains in India and is the staple food for a significant portion of the world‟s population. Widely varying factors influence the growth of rice in different rice growing areas and render the crop susceptible to various pathogenic and non-pathogenic diseases, resulting in extensive damage of grain and straw yield. Bacterial leaf blight disease of rice caused by Xanthomonas oryzae pv. oryzae (Xoo) is a serious menace to rice production in India, besides other rice producing countries.

Biotic and abiotic stresses are major constraints in the production of groundnut. Among biotic stresses apart from bacterial and viral diseases, many fungal diseases are of economic importance. The major fungal diseases are Early leaf spot (Cercospora arachidicola), Late leaf spot (Cercosporidium personatum), Rust (Puccinia arachidis), Botrytis blight (Botrytis cinera), Aflarot/Yellow mould (Aspergillus flavus), Damping off (Pythium spp.

Cotton is a very important commercial crop of India and to the world. Essentially used for fibre, fuel and edible oil and various other purposes. It is important because it is cash crop to the farmers. Out of 30 diseases known to occur in cotton crop from time to time, the bacterial blight is the most wide spread and destructive disease reported to cause yield losses of about 10 to 30 per cent.

The front line demonstrations (FLD’s) on Arka Rakshak F1 Hybrid of tomato were conducted by Krishi Vigan Kendra of Ramanagara District, Karnataka. Akra Rakshak, a triple disease resistant (bacterial wilt, early blight and leaf curl virus) hybrid was released by Indian Institute of Horticultural Research (IIHR), Bengaluru. Improved crop management practices were demonstrated in farmers field for three consecutive years from 2014-15 to 2016-17. As an outcome of FLD, it was noticed that the average per cent Bacterial wilt affected plants was low in demo plots (1.
