Plant Growth Promotion and Suppression of Bacterial Leaf Blight in Rice by Inoculated Bacteria
The present study was conducted to evaluate the potential of rice rhizosphere associated antagonistic bacteria for growth promotion and disease suppression of bacterial leaf blight (BLB). A total of 811 rhizospheric bacteria were isolated and screened against 3 prevalent strains of BLB pathogen Xanthomonas oryzae pv. oryzae (Xoo) of which five antagonistic bacteria, i.e., Pseudomonas spp. E227,...
متن کاملGenetic Diversity of Bacterial Leaf Blight Disease in a Set of Rice Landraces of West Bengal
Bacterial Leaf Blight (BLB) is a major disease of rice in tropical monsoon and sub tropical rice growing regions of the world. BLB substantially reduces the yield of the crop affecting food security. Rice is the second most important food crop, after wheat, in the world; hence the disease must be effectively controlled. As chemical control is impractical due to unavailability of specific bacter...
متن کاملLong-term effect of niclosamide on inhibition of bacterial leaf blight in rice
Bacterial leaf blight is one of the major diseases in rice and affects yields. Thus, various methods have been applied to protect rice from this disease. Here, we show systemic translocation of the human drug niclosamide (5-chloro-N-(2-chloro-4-nitrophenyl)2-hydroxybenzamide) in rice and its long-term effect on prevention of rice leaf blight. The development of Xanthomonas oryzae pv. oryzae-ind...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Biological control of rice bacterial blight by plant-associated bacteria producing 2,4-diacetylphloroglucinol.
Certain plant-associated strains of fluorescent Pseudomonas spp. are known to produce the antimicrobial antibiotic 2,4-diacetylphloroglucinol (DAPG). It has antibacterial, antifungal, antiviral, and antihelminthic properties and has played a significant role in the biological control of tobacco, wheat, and sugar beet diseases. It has never been reported from India and has not been implicated in...
