ब्रैसिका और फफूंद के अन्योन्यक्रिया का अध्ययन और उनके महत्व Less attention has been paid by researchers to phytotoxins and their role in the resistance of different Brassica species, especially in mustard (B. juncea). Pathogens are often resistant to plant defense compounds. This can happen for a variety of reasons including the plant's ability to degrade and convert defense compounds into less toxic compounds or the complete breakdown of defense compounds. This property enables the fungus to enter plant tissue and infect the plant. ब्रैसिका और फफूंद के अन्योन्यक्रिया का अध्ययन और उनके महत्व दुनिया भर में सरसो (ब्रैसिका) का महत्व इसके बीजों से निकलने वाले तेल के अतिरिक्त दैनिक भोजन के रूप...

स्यूडोमोनास फल्‍योरेसेन्‍स की फफूंद रोगाणुओं केे जैव नियंत्रण की क्षमता। Plant diseases cause 13 - 20 % losses in crop production worldwide. Control of plant disease by chemical can be spectacular but the accumulation of harmful chemical residue sometimes causes serious ecological problems. Biocontrol agents are economical, suppress the inoculum load of the target pathogen, long lasting and free from residual side effect. Fungi in the genus Trichoderma and Bacteria in the genera of Pseudomonas and Bacillus are increasing interest as bioprotectants against plant diseases. Biocontrol agents in general and Pseudomonas fluorescens in particularhave gained importance as a component of Integrated Pest Management for sustainable agriculture (Mukhopadhyay, 1987).  Pseudomonas fluorescens belong...
