Biography:

M Anowarul Islam is currently working as an Associate Professor at the Department of Plant Sciences of University of Wyoming, USA. His research and outreach activities aim to develop modern and innovative research and outreach programs on Agronomy that includes: germplasm search and evaluation for selection/cultivar development; establishment and Best Management Practices (BMP) for profitable and sustainable crops and livestock production;grazing management and integration with cropping systems; establishment and incorporation of legumes (e.g., alfalfa, sainfoin, birdsfoot trefoil; cicer milkvetch, medics) into the grass systems; alternative/multipurpose use of forages, e.g., bioenergy crops(switchgrass), specialty crops (fenugreek, quinoa, chick pea), small grains; forage nutritive value and seed production. Additionally, he teaches courses (Forage Crop Science, Thesis Research, Dissertation Research, Research Apprenticeship, and Research in Crops) and advises undergraduate and mentors graduate students.

Abstract:

Forage crops play a major role in the nation’s economy, especially in the economy of the western states of USA due to presence of vast grasslands. However, forage yields in these states have been declining. For example, in Wyoming, forage yields are below the national average over the past few years. There are a number of factors that contribute to this low productivity and sustainability. Examples include declining plant diversity, reduction of biodiversity, less adapted plant species, monoculture practices, and soil degradation, especially soil mining. Many studies conducted locally, regionally, and internationally suggest that maintaining plant diversity with adapted species is important for the productivity, efficiency, and resiliency of grassland production systems. For instance, a recent extensive review shows that mixtures of species produce an average of 1.7 times more biomass than species monocultures and are more productive than the monoculture. Also, it is shown that, in some experiments, diverse polycultures achieve greater biomass than their single most productive species. The net effect of diversity and the probability of polycultures are more productive than their most productive species which increases through time. This occurs because of the magnitude of complementarity which increases when the experiments are run for a longer time. Also, it is shown at eight European field sites, a simulated study by synthesizing grassland communities with different numbers of plant species, that there is an overall log-linear reduction of average aboveground biomass with loss of species. Field studies being conducted at different locations in Wyoming demonstrate that mixtures (binary or polycultures) produce more biomass with high quality compared to monoculture. There are also positive impacts of mixtures on stand persistence, soil properties and environment, microbial population, and economic returns. Details about plant diversity and its impacts will be discussed in the presentation.

Biography:

Mohammad Babadoost received his MS in Plant Pathology from Washington State University and PhD in Plant Pathology from North Carolina State University. In 1999, he joined the faculty of the University of Illinois at Urbana-Champaign, and he is now Professor of Plant Pathology and Extension Specialist. He conducts research and extension programs on the biology and management of vegetable and fruit crops diseases, and teaches “Plant Disease Diagnosis and Management” and “Outreach Education Skills.” He has served as an Editor of the APS-FNT and ASHS HortTechnology and as a Reviewer for more than 20 journals. He has published 1 book, 4 book chapters, 1 monograph, 10 bulletins, 51 refereed articles, 86 articles in proceedings, 88 abstracts, and 175 articles in newsletters. He has developed a profound commitment to sharing his expertise in developing countries to advance the science of plant pathology and establishing food security in the world.

Abstract:

Bacterial spot of cucurbits, caused by Xanthomonas cucurbitae, is an emerging disease in the United States (US) and other cucurbit growing areas of the world. The pathogen can infect all cucurbit crops, but its major hosts are pumpkins and winter squash. Leaves and fruits of cucurbits are infected by X. cucurbitae at all growth stages. Infected fruits are usually colonized by opportunistic fungi and bacteria and rot. Our surveys in the North Central Region if the US during 2012-2013 showed that 159 of 180 and 71 of 79 of pumpkin and squash fields, respectively, had fruits infected with X. cucurbitae. The average incidence of fruits with bacterial spot in all pumpkin and squash fields surveyed was 25 and 19%, respectively. We identify the pathogen based on the colony morphology on yeast dextrose agar (YDC), polymerase chain reaction (PCR) test using RST2/RST3 primers, and pathogenicity test on susceptible pumpkin ‘Howden’. X. cucurbitae survived in infected leaves and fruits in the field for more than 24 months. Also, X. cucurbitae survived longer than 18 months in the seeds at 4 and 22°C and remained viable. No cultivar of cucurbits resistant to X. cucurbitae is available. We eradicated the pathogen in the naturally-infected and artificially infested seeds by hot-water treatment at 55°C for 15 min and HCl treatment at 0.5% concentration for 40 min. Also, in our field trials, copper oxychloride + copper hydroxide (Badge X2 DF), copper sulfate (Cuprofix Ultra 40 DF), oxytetracycline (Mycoshield 40 WSP), copper sulfate pentahydrate (Phyton-016B), copper hydroxide (Kocide-3000 46.1 DF) plus acibenzolar-s-methyl (ActiGard 50 WG), Kocide-3000 46.1 DF plus famoxadone + cymoxanil (Tanos 50D WG), an extract from Reynoutria sachalinensis (Regalia), and B. subtilis (Serenade ASO) were effective in reducing incidence and severity of bacterial spot on both leaves and fruits compared to controls.

Biography:

N Nagaraju graduated in University of Agricultural Sciences Bengaluru and expertise in Plant Virology. He worked as an Extension Pathologist during 1998-2010 and expertise in diagnosis, identification of plant disease and recommending suitable management practices. He is serving in UAS, Bengaluru since 20 years and worked on different plant viruses viz., Papaya ring spot virus (PRSV), Pepper veinal mottle virus (PVMV), Cucumber Mosaic Virus (CMV), Tomato leaf curl virus (ToLCV), Tomato spotted wilt virus (ToSPO) and other Gemini viruses. He developed integrated management practices for the important viruses for sustainable agriculture and were included in University Package of Practice. He is presently working on use of bio-molecules for inducing defense in crop plant against plant viruses.  

Abstract:

Papaya cultivation is worldwide ravaged by Papaya ringspot virus (PRSV) disease. Surveys conducted in Southern Karnataka during 2012-2014 revealed the maximum PRSV incidence in Bangalore Rural (77.53%) followed by Bangalore Urban (68.89%), Kolar (65.00%) and Chikkaballapura (52.78%) districts. Monitoring of the population of different aphid species during August-2013 to July-2014 using yellow sticky traps revealed the occurrence of eight aphid species. Of which, three species viz., Aphis gossypii (66.04%), A. craccivora (26.80%) and Myzus persicae (2.12%) were regularly trapped throughout the year. Transmission studies proved that, M. persicae (53.33%) was more efficient vector in transmitting PRSV followed by A. gossypii (46.66%) and A. craccivora (26.66%). The aphid population was peak when rainfall was below 8.00 mm with temperature range of 17-350C, relative humidity of 30-90% and with wind speed of 3-5km/hr. Based on the symptoms on differential var. Red lady, the PRSV isolates viz., BRD-1, BRH-1, BUH-1 were considered as severe, while MMD-1 and MML-1 as mild isolates. Partial characterization of isolate BUH-1 by CP gene showed highest homology of 98% with South Indian and 87-92% with Asian isolates. Among the defence inducing molecules Salicylic Acid@ 0.002%, Silicic Acid@ 0.2% and Boric Acid@ 0.2% found effective in reducing the disease under field and glasshouse condition. In PRSVdisease management studies, growing papaya as intercrop with African Tall maize (1:1) and Grand Naine banana
