By incorporating high-throughput technologies into the breeding process, we can make more accurate and informed decisions when selecting new varieties. For this reason, we are integrating genomic and phenomic data into our breeding process.<\/p>\n<p><em>Leveraging Spectral Data in Potato Breeding Selection and Detecting PVY<br \/>\nby Salem Ermish, <\/em><em>Graduate Student, in Dr. Mario Andrade, and Dr. Ek Han Tan\u2019s lab.<br \/>\n<\/em>A key aspect of the breeding process involves screening for disease resistance, such as PVY, a major threat to potatoes that causes significant yield loss and seed production issues. Each year, the UMaine Potato Breeding program evaluates numerous clones to measure their resistance and symptom expression to PVY infection. While symptom assessment traditionally relies on visual assessments, we are coupling advanced technology such as multispectral and hyperspectral data collected via UAV and handheld devices. This data aims to detect PVY infections in the field through spectral analysis.<\/p>\n<h4><strong>USDA\u2013ARS Breeding Program<\/strong><\/h4>\n<p><em>Evaluating 2,4-D Concentrations and Variety Tolerance for Common Scab Control in Potatoes<\/em><br \/>\n<em>by Dr. Paul Collins, USDA\u2013ARS<br \/>\n<\/em>This field is deliberately maintained with an infection of common scab for research. USDA\u2013ARS is testing three concentrations of 2,4-D as a control method to reduce the incidence of scab symptoms while maintaining yield. There is also a long-term soil sampling study to determine the effect of planting tolerant and susceptible varieties on the amount of scab pathogens present in the soil.<\/p>\n<h4><strong>Potato Pathologist Program<\/strong><\/h4>\n<p><em>Potato Varietal Studies for Pink Rot Resistance<\/em><br \/>\n<em>by Lydia Teng, Graduate Student, in Dr. Jay Hao\u2019s lab, School of Food and Agriculture<br \/>\n<\/em>The trial is to test the susceptibility of 45 potato clones along with 12 standard varieties for their resistance to potato pink rot. The field was infested with the pathogen Phytophthora erythroseptica at planting.<\/p>\n<p><em>Interactions between Metam Sodium and Soil Microbial Communities in Controlling Verticillium Wilt of Potatoes<\/em><br \/>\n<em>by Shayli Morris, Graduate Student, in Dr. Jay Hao\u2019s lab, School of Food and Agriculture<br \/>\n<\/em>Examining the efficacy of successive soil treatments with metam sodium as a treatment for Verticillium wilt of potatoes, while also exploring the impacts on the soil microbial community to identify possible metam sodium-degrading microbes.<\/p>\n<h4><strong>Agronomy Program<\/strong><\/h4>\n<p><em>Tailoring Spacing to Potato Varieties: Enhancing Growth and Yield<\/em><br \/>\n<em>by Chloe Sleepers, undergraduate student, in Dr. Mario Andrade\u2019s lab<br \/>\n<\/em>Optimal spacing is crucial for maximizing potato yield and quality. This study investigates the effects of varying plant spacing on four different potato varieties, aiming to determine the ideal conditions for each type. Field trials were conducted with multiple potato varieties at different spacing intervals. Implementing variety-specific spacing can enhance nutrient utilization, reduce disease incidence, and ultimately improve both yield and crop quality in potato production.<\/p>\n<p><em>Phosphorus Management in Potato Production<\/em><br \/>\n<em>by Dr. Bee Khim Chim, UMaine Extension<br \/>\n<\/em>No phosphorus for two years in a row? Does it affect yield, quality, and plant size? This study aims to evaluate the effect of different rates of phosphorus fertilizers for their impact on productivity, plant, soil, and quality of potatoes.<\/p>\n<p><em>Improving Land Utilization Efficiency and Return on Investment (ROI) with Twin-Row Potato Planting in Northern Maine<\/em><br \/>\n<em>by Dr. Bee Khim Chim, UMaine Extension<br \/>\n<\/em>This study examines twin-row potato planting in Northern Maine to optimize land use efficiency. Unlike the traditional 36-inch single-row method, twin-row planting places two rows with a single hill between them, spaced 42 inches apart. This technique aims to increase potato yield per unit area and enhance profitability.<\/p>\n<h4><strong>Potato Pathologist Program<\/strong><\/h4>\n<p><em>Effects of Seed Treatment Practices on Potato Stand and Yield on Two Varieties<\/em><br \/>\n<em>by Dr. I. Kutay Ozturk, UMaine Extension<br \/>\n<\/em>Kutay\u2019s field trial investigates how liquid seed treatment, seed piece suberization, and potato variety interact on potato stand, grade, and yield. Findings of this trial will help provide potato growers more opportunities to tailor best management practices for seed piece health. Kutay is also growing a small set of powdery scab susceptible potato plants to generate material for multiple projects. These projects include developing an efficient soil quantification method for the powdery scab pathogen and understanding host-pathogen interactions.<\/p>\n<p><em>Evaluation of Orondis Gold for the Control of Pink Rot<\/em><br \/>\n<em>by Lydia Teng, Graduate Student, in Dr. Jay Hao\u2019s lab, School of Food and Agriculture<br \/>\n<\/em>The trial is to evaluate the efficacy of Orondis Gold (oxathiapiprolin + mefenoxam). Other chemical treatments include Revus, Elumin, and Ridomil Gold, applied either as seed treatment or in-furrow treatment.<\/p>\n<p><em>Optimization of Chemical Control on Alternaira Diseases of Potatoes Based on Disease Forecasting<\/em><br \/>\n<em>by Chris Fan, Graduate Student, Dr. Jay Hao\u2019s lab, School of Food and Agriculture<br \/>\n<\/em>Potato diseases caused by Alternaria spp. will be monitored using spore trapping, plant inspection, and forecasting models. Foliar applications of fungicides will be conducted, and the treatments arranged either on a regular basis or dictated by the forecasting system. The goal is to save sprays and costs by predicting the disease development.<\/p>\n<h4><strong>USDA\u2013ARS Breeding Program<\/strong><\/h4>\n<p><em>Maintaining Historical Potato Varieties for Breeding, Nitrogen Efficiency, and Heat Tolerance<\/em><br \/>\n<em>by Dr. Paul Collins, USDA\u2013ARS<br \/>\n<\/em>USDA-ARS has a collection of 270 named historical varieties which are maintained annually as 12 hills plots. Some of these varieties are used as breeding parents for chipper and table crosses. The population is also screened for nitrogen use efficiency and heat tolerance with collaborators at the University of Florida.<\/p>\n<h4><strong>Entomology Program<\/strong><\/h4>\n<p><em>Current IPM Options for Insect Pests of Potatoes<\/em><br \/>\n<em>by Dr. Andrei Alyokhin, School of Biology and Ecology<br \/>\n<\/em>We develop IPM solutions for managing insect pests of potatoes at the time when the efficacy and availability of neonicotinoid insecticides are increasingly uncertain. We test various experimental insecticide programs, with a particular emphasis on novel modes of action. We also develop remote sensing approaches to scouting for potato pests.<\/p>\n<p><em>PVY Demonstration trials<\/em><br \/>\n<em>by Dr. I. Kutay Ozturk, UMaine Extension<br \/>\n<\/em>In the PVY demonstration plot, Kutay is collaborating with the UMaine IPM program to provide visual demonstration of three PVY strains on 19 potato varieties. This demonstration plot helps growers, rouging crews, and seed potato certification program inspectors on gaining experience with identifying PVY on the field.<\/p>\n<p><strong>3.30 p.m. <\/strong>\u2013 Adjourn<\/p>\n<h3><strong>Speakers<\/strong><\/h3>\n<p><strong>Dr. Andrei Alyokhin<\/strong> is a Professor of Applied Entomology in the School of Biology and Ecology and the Experiment Station at the University of Maine.
