Abstract:

Chemical fertilizers and pesticides have been heavily used in agriculture and horticulture food production, resulting in serious concerns including food safety and eco-system sustainability. Plant growth promoting bacteria are able to improve plant health and productivity and reduce pathogens and diseases, representing an ecologically-friendly alternative to chemical fertilizers and pesticides.  We recently isolated various beneficial bacterial species including Paenibacillus polymyxa CR1 (BMC Genomics 2014;   Frontiers in Microbiology 2015;  BMC Microbiology 2016);  Bacillus velezensis strain 9D-6 (BMC Microbiology 2019);  Bacillus velezensis strain 1B-23 (GenBank Accession: NZ_CP033967.1) and Burkholderia cenocepacia CR318 (Genome Announcements 2017). These beneficial bacteria are capable of promoting crop health and inhibiting the growth of wide range of bacterial and fungal pathogens. In particular, Bacillus velezensis strain 9D-6 and 1B-23 produce surfactin, the most powerful biosurfactant. Surfactin aids in biocontrol through its antimicrobial action and through contribution to reducing biofilm formation.  Our study further indicated that Bacillus velezensis strain 9D-6 and 1B-23 protect tomato plants from bacterial canker disease caused by Clavibacter michiganensis pv michiganensis.  Interestingly, we found strain 1B-23 produces surfactin more efficiently at temperature between 16 to 20 °C.  Our results suggest the potential of using beneficial bacteria to develop inoculants to protect agricultural important crops while reducing the use of chemical fertilizers and pesticides, towards more sustainable agriculture and horticulture.

Abstract:

Crop water stress index (CWSI) has been recognized as a water stress indicator and as a potential tool for irrigation scheduling. In present study, CWSI calculated based minimizing the low temperature impact was suitable to improve the precision of water stress monitoring. Thermal images were taken with FLIR thermal infrared imager at 14:00. Upper, sunlit and non-covered temperatures derived from canopy images, and canopy temperature cumulative frequency curves were discovered as discrete distribution under different degrees of water stress. CWSI used canopy temperature as the main driver for evaluation, and was calculated based on average temperature over a certain quantile. Regression equation between different CWSI and photosynthetic activity were built to find which one is the most sensitive index. Statistical analysis revealed that higher correlation coefficients were found after minimizing the low temperature. Further, the most sensitive CWSI also showed better relation to root soil moisture. CWSI thresholds were redefined. Optimal diagnose of the water stress was based on reasonably using canopy temperature. The results of this study were promising in precise irrigation scheduling.

 

Session Introduction

Lorenzo Labrador

World Meteorological Organization, United Kingdom

Title: Measurement-Model Fusion for Global Total Atmospheric Deposition
Biography:

Lorenzo Labrador is a Scientific Officer at the world Meteorological Organization’s (WMO)  Global Atmosphere Watch (GAW) Programme. He currently coordinates the activities of three Scientific Advisory Groups to  WMO and also coordinates the research-to-services Measurement-Model-Fusion project, aimed at producing global maps of total deposition of atmospheric pollutants on an operational or semi-operational basis.  Lorenzo trained as a physicist and went on to obtain a Ph.D in atmospheric Sciences from the Max Planck Institute for Chemistry in Mainz, Germany and the University of Heidelberg in Germany in 2005. After working in academia researching atmospheric chemistry for a number of years, Lorenzo moved to the UK’s Met Office in 2015 to work in the Satellite Applications Group, where he worked on developing deep convection products using satellite imagery. In 2018, Lorenzo started working in WMO’s GAW programme.  Lorenzo has a number of publications in peer-reviewed journals, dealing mostly on the subject of atmospheric chemistry

Abstract:

The World Meteorological Organization’s (WMO) Global Atmosphere Watch (GAW) Programme coordinates high-quality observations of atmospheric composition from global to local scales with the aim to drive high-quality and high-impact science while co-producing a new generation of products and services. Exposure to atmospheric ozone is a major factor in crop yield  losses in many countries, resulting in billions of US $ in losses and having implications for future food security. Likewise deposition of excess atmospheric nitrogen can result in eutrophication of freshwater bodies, with potential impacts on the health of  water bodies  used for irrigation. Conversely, agriculture is the single largest contributor of ammonia pollution as well as emitting other nitrogen compounds, some of which can make it into the atmosphere and be deposited, potentially affecting crops elsewhere. To better understand and address the issues posed by deposition of atmospheric pollutants, WMO has a mandate to produce global maps of wet, dry and total atmospheric deposition for important atmospheric chemicals to enable research into biogeochemical cycles and assessments of ecosystem, food security and  human health effects. The most suitable scientific approach for this activity is the emerging technique of measurement-model fusion for total atmospheric deposition. This technique requires global scale measurements of atmospheric trace gases, particles, precipitation composition and precipitation depth, as well as predictions of the same from global/regional chemical transport models. The fusion of measurement and model results requires data assimilation and mapping techniques.

Qi Wei, Male, Postdoctor in Hohai Univeraity. Mainly focused on High efficiency local irrigation and its greenhouse gas emissions  so on, and published more than 30 papers in the last 5 years.

 

Abstract:

Irrigation of brackish water (2-5 g L-1) instead of fresh water, modify soil microbial activities such as carbon and nitrogen cycle, and thus affect soil emissions of nitrous oxide (N2O) and carbon dioxide (CO2). However, the effects of irrigation salinity on global warming potentials (GWPs) caused by N2O and CO2 emissions are rarely investigated. Pot experiments with three irrigation salinity levels (2, 5 and 8 g L-1) were designed to study the responses of GWPs and the contribution of N2O and CO2 to various salinity levels. Results indicated that soil CO2 flux reduced with the increase of irrigation salinity and was obviously lower than that from fresh water irrigated soil (CK). By comparison, for N2O, 2 and 8 g L-1 saline water decreased the cumulative fluxes by 22.6% and 39.6% compare to CK (p<0.05), respectively, whereas 5 g L-1 saline water enhanced it by 87.7%. Overall, the cumulative GWPs of N2O and CO2 from irrigated soils using saline water (2-8 g L-1) were 3.2%-51.1% lower than that from CK, with the relative change to CK at 2 g L-1 salinity level significantly higher than those at 5 g L-1 salinity level. These results suggested that the degree to which soil Ec affected soil microbial processes might vary significantly among irrigation salinity ranges. Reducing the salinity of irrigated brackish water can mitigate soil GHGs and provides a potential strategy for solving water resources scarcity and reducing soil salt accumulation.

Abstract:

Clubroot, caused by Plasmodiophora Brassicae, is a serious soil-borne disease in worldwide. In recent years, progression of clubroot is rapid and serious in Shanghai, China. In this study,  The inheritance of clubroot resistance (CR) were determined in pakchoi using F2 segregation population that were developed by crossing highly resistant line ‘CR38’ and susceptible line ‘CS22’. Two novel QTLs, qBrCR38-1 and qBrCR38-2, was identified by BSA-seq (Bulked Segregant Sequencing) resistant to P. brassicae physiological race 7. Two significant peak qBrCR38-1 and qBrCR38-2 were observed by three statistical methods between interval of 19.7-20.6Mb in chromosome A07 and 20.0-20.6Mb in chromosome A08, respectively. In addition, Polymorphic SNPs identified within target regions were converted to kompetitive allele-specific PCR (KASP) assays. In target regions of qBrCR38-1 and qBrCR38-2, there were twenty SNP sites identified, eleven KASP markers of which are significantly associated to CR (P<0.05). Seven candidate genes were identified and found to be involved in disease resistance (TIR-NBS-LRR proteins), defense responses of bacterium and fungi and biotic/abiotic stress response in the target regions harboring the two QTLs.  Two novel QTLs and candidate genes identified from the present.

Abstract:

Statement of the Problem: Irrigation mode is an important factor in regulating ecosystem services from croplands. However, there are no studies on the effects of rice irrigation mode practiced on the ecosystem service value (ESV) of paddy fields. Methodology & Theoretical Orientation: Thus, we present the results of a field experiment study of ecosystem services and their economic values provided by paddy fields under different irrigation modes in Taihu Lake region of China. Conclusion & Significance: The results showed that nine kinds of rice paddy ecosystem services were clearly affected by irrigation mode of rice. Compared to traditional flooding irrigation (FI), controlled irrigation (CI) led to more than half reduction of irrigation water input while maintaining high rice yield. The positive ESV of CI paddy fields were reduced by 10.00% due to the reduction of air temperature, groundwater conservation and soil organic matter accumulation values. Meanwhile, application of water-saving irrigation also reduced negative ESV of paddy fields by 38.20% compared to FI treatment. CI management significant reduced the negative ESV of agricultural non-point source pollution and water resource depletion by 61.27% and 25.47%. In summary, total ESV of CI paddies were 43.41 ×103 CNY ha-1, reduced on average by 3.43% compared to FI fields.  According to the results of this study, 4.85 billion m3 of irrigation water will be saved and 1.83 billion CNY of ecosystem service value provided by gas exchange in paddy field will be increased in the event of a comprehensive promotion of rice water-saving irrigation in the Taihu Lake region of China. Our results suggest that CI can increase the ESV of paddy fields while drastically reducing irrigation water input and ensuring the crop yields.

Abstract:

Statement of the Problem: As being the first cultivated wheat in the Fertile Crescent, diploid einkorn wheat (2n=2x=14, AA), Triticum monococcum L. subs. monococcum, was domesticated 9500 years ago in Karacadag Mountains of South-East Turkey. Nowadays it has been grown in only marginal lands of Turkey, Caucasus, Europe and Morocco. After having disappeared because of its replacement by high yielding modern wheat cultivars, recently einkorn wheat has been re-introduced in some countries, especially for organic farming, due to its high resistance to pests and diseases, adaptation to harsh climates, ability to provide acceptable yields on poor soils even with low/without inputs and high nutritional value. In order to maintain and utilize the genetic diversity of einkorn wheat, it is necessary to develop in situ conservation program to provide continuity of cultivation of its landraces; characterizing, analyzing and documenting of its accessions and identifying its genes for useful agronomical and nutritional traits to employ in breeding programs.   Materials and Methods: Local 45 einkorn wheat lines, selected from 500 single rows planted by each single spikes collected from 50 farmers’ fields in Kastamonu/Turkey, were sown in autumn (9 November 2017) and in spring (20 February 2018) and were harvested on 30-31 July 2018 and on 8 August 2018, respectively. Morphologic and agronomic traits were observed and measured during growing period of plants and quality properties of harvested seeds were determined by using “Single Kernel Characterization System (SKCS)”. Findings: All of the einkorn wheat lines in the trial showed “facultative” growth habit, flowering well when sown both in autumn and in spring. Although lines sown in autumn had more yield, the same lines sown in spring provided higher quality and more resistance to lodging due to being shorter. Conclusions: Einkorn wheat lines sown in autumn and in spring seasons showed a significant variation for traits, which can be used for einkorn breeding program.

Abstract:

Statement of the Problem: United States land grant universities have a third mission in addition to research and teaching, called Extension. At the University of Florida (UF) Extension is located within the Institute of Food and Agricultural Sciences (IFAS) and is called UF/IFAS Extension. Extension agents/educators provide research-based, practical information to agricultural producers and other clients. South Florida’s subtropical climate allows for production of a variety of crops, however, the same favorable environmental conditions are also ideal for many production challenges year-round.

Methodology & Theoretical Orientation: UF/IFAS Extension faculty developed, implemented and evaluated educational programs outcomes and impacts in commercial agriculture production for five years in south Florida. Programs delivered included classroom workshops, one–on-one consultations and site visits to nurseries.

Findings: The UF/IFAS Commercial Agriculture/Ornamental Extension Agent trained 2,245 participants in 64 Integrated Pest Management (IPM) workshops conducted in English and Spanish.  652 participants out of 1,165 (55.9%) answered a survey and reported an average class satisfaction of 4.4 out of 5.0 Likert scale (Where 1= least, 5= greatest value) and knowledge gain of 4.0 out of 5.0 in identification of pests threatening south Florida agriculture. Training covered such pests as Oriental Fruit Fly (OFF) and Giant African Land Snail (GALS), including their management.

Conclusion & Significance: To date UF/IFAS Extension continues to provide timely and relevant tropical agricultural education on a variety of topics to producers who rely on unbiased and research-based educational trainings. It is estimated than for every $1 invested in agricultural research and Extension, there is a return of $20 to the community.

 

Biography:

Sarah Bliss has been involved with Wobelea Pty Ltd since 1991. During this time the first post-harvest disinfectant for agricultural fruit and vegetable washing in Australia was developed by Wobelea Pty Ltd. In recent years Sarah has worked on developing new technology based on food additives for pre and post-harvest applications in the agricultural industry. Sarah has commented on the issues surrounding Melon Safety and pathogens affecting Mango’s and is passionate about ensuring new knowledge is passed onto growers. Sarah has worked ensuring recent field trials of the new technology were developed in conjunction with Peracto Pty Ltd, Tasmania (2017-18) to ensure efficacy and residue data were collected to support registration.

Sarah is passionate about correctly identifying critical control points from paddock to plate and using new technology to disinfect water to allow for future opportunities to bridge the gap between technology and growers. Knowledge is key to ensure quality water is used on growing crops to reduce harmful pathogens in the field, thus reducing the pathogen loading in the packing, storing and transport of produce.

 

Abstract:

 

Quality water, filtration and minimal chemical use is the future way to provide healthy safe produce. Focus has shifted dramatically as concerns with Food Safety and Quality Control become important to growers and consumers.
Understanding the chain of food handling, providing education and solutions, using chemicals within correct parameters and ensuring wash or irrigation water has reduced pathogen loading will enhance Food Safety and reduce risk of crop loss and human health scares.
Our research shows advantages of using disinfectant actives to reduce level of pathogens found pre harvest, post-harvest, on equipment and in storage and transport. Disinfection systems that incorporate sand filtration and automatic chemical dosing are effective in reducing pathogen loading whilst controlling the amount of chemical used. Minimal by-products (dependant on disinfectant used) are formed in recirculated wash water and can be maintained by the addition of fresh water. Alternatively run to waste systems can be used. Water that passes through sand filters or slow speed filtration (IHD Knoxfield, 1999) effectively removes a large percentage of fungi and bacteria loading. Efficacy was shown at reducing Fungi spores from 60 spores/ml to 10 spores/ml when a sand filter with flocculant was used.
Our research growth consists of reviewing farm management practises, ensuring water quality is free of pathogens and developing a new formulation based on known food additives and other actives, as a pre harvest and post-harvest spray to remove pathogen loading. Water quality is of utmost importance in the growing and washing of produce. Consumers demand quality produce that is free of harmful pathogens.
Conclusion: Combining the use of filtration and disinfectants significantly reduces pathogen loading on wash water and irrigation water. Education is required on chemical selection, defining critical control points from growing crops, washing and packing, storage and transport to end customer.
