• I, P. Bharat Chandra Working as Maize Pathologist In Acharya N.G Ranga Agricultural University, Andhra Pradesh , India. My research programs will include Farmer training, coordination with grower/producers groups, plant disease fact sheets, as well as plant disease control and management options based on field trials and experiments. Applied research will involve characterizing plant pathogens and the diseases they cause in order to implement practices. I provide advice, guidance, innovative solutions and links to several research groups involved in international agricultural research and development. My effort to modernize the field trials included the implementation of breeding data management software and databases to facilitate management and coordination, improve efficiencies and simplify decisions and selections. Execute provide leadership in improvement program of center, which focuses on developing improved lines resistant to diseases and major biotic stresses.

corn secretes copious globs of mucus-like gel out of arrays of aerial roots along its stalk. This gel harbors bacteria that convert atmospheric nitrogen into a form usable by the plant, a process called nitrogen fixation. The corn can acquire 30 to 80 percent of its nitrogen in this way, but the effectiveness depends on environmental factors like humidity and rain. “It has been a long-term dream to transfer the ability to associate with nitrogen-fixing bacteria from legumes to cereals .Legumes, such as beans, are the only group of crop plants previously known to acquire a significant amount of nitrogen through fixation, which they perform in specialized tissue Scientists have long sought corn that could fix nitrogen, with the goal of reducing the crop’s high demand for artificial fertilizers, which are energy intensive, expensive and polluting. Further research is required to determine if the trait can be bred into commercial cultivars of corn, the world’s most productive cereal crop.
During Kharif 2019, Pokkah boeng like symptoms were observed in fourty day’s old crop of some commercial maize hybrids grown in Andhra Pradesh, India. Afected foliage turned pale with occasional twisting of young foliage followed by rotting of the leaf whorls in advanced stages of infection. The pathogen was isolated from the diseased sample in pure form and pathogenicity was proved by artifcial inoculation. The pathogen was characterized by PCR amplifcation of Internal Transcribed Spacer region of ribosomal DNA and identifed as Fusarium lufae.
Post flowering stalk rot is considered as a devastating menace of the most prevalent fungus on maize, growing areas of andhra pradesh in india. It causes Fusarium stalk rot on plants, which is considered as major threat to production of maize, accompanied by small losses to total wipeout of the crop. This disease is more prevalent in area where water stress occurs after flowering stage of the crop. Owing to its soil borne infection pathway, fungicidal control of Fusarium stalk rot is not effective. A number of quantitative trait loci have been identified which will help to expedite breeding program against Fusarium stalk rot. Moreover, various chemical and biological control methods have been developed, but major emphasis is on development of maize cultivars with genetic resistance to Fusarium stalk rot for environment friendly control of the disease. Sustainable maize cultivation is continuously challenged by diseases that cause quantitative and qualitative losses in yield.
