    Monitoring of Overwintering Pepper Weevil in Southern Georgia

    New

    This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in the 2024-2025 growing season. Pepper weevil is a key insect pest of peppers; in Georgia, overwintering monitoring of weevil populations has demonstrated that pepper weevil now overwinters throughout southern Georgia, including all of our primary pepper production areas. Contributing authors include county and regional faculty as well as specialists from UGA’s horticulture, plant pathology, crop and soil sciences, and entomology departments. All research has been supported by the Georgia Commodity Commission for Vegetables.

    Bell Pepper Breeding for Phytophthora Resistance

    New

    A comprehensive research strategy was created in our vegetable breeding program to meet the needs of bell pepper growers. Identifying potential resistant gene sources against Phytophthora capsica is one of those efforts. This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in the 2024-2025 growing season. Contributing authors include county and regional faculty as well as specialists from UGA’s horticulture, plant pathology, crop and soil sciences, and entomology departments. All research has been supported by the Georgia Commodity Commission for Vegetables.

    Evaluation of Preplant Potassium Sources for Pepper Production

    New

    This research aims to compare sulfate of potash and muriate of potash in a plasticulture system because muriate of potash costs less per unit of K. There is relatively little research comparing sulfate of potash to muriate of potash in vegetable production systems. This research aims to compare sulfate of potash and muriate of potash in a plasticulture system. This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in the 2024-2025 growing season. All research has been supported by the Georgia Commodity Commission for Vegetables.

    Evaluation of Specialty Pepper Varieties for Marketable Yield and Fruit Size in Spring 2024

    New

    This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in the 2024-2025 growing season. Fresh-market pepper production continues to grow as consumer demand increases for specialty peppers. However, selecting the best variety can be challenging because yield potential and fruit dimensions vary widely among jalapeño, serrano, poblano, and banana types. Contributing authors include county and regional faculty as well as specialists from UGA’s horticulture, plant pathology, crop and soil sciences, and entomology departments. All research has been supported by the Georgia Commodity Commission for Vegetables.

    Evaluation of Biological and Chemical Products for Managing Bacterial Leaf Spot in Bell Pepper in Georgia

    New

    This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in the 2024-2025 growing season. In this article, the authors investigate whether biological and chemical antimicrobial products would reduce disease severity of leaf spot and blight in bell peppers under field conditions. Contributing authors include county and regional faculty as well as specialists from UGA’s horticulture, plant pathology, crop and soil sciences, and entomology departments. All research has been supported by the Georgia Commodity Commission for Vegetables.

    Precision Disease Management for Southeastern Vegetable Crops to Improve Agrochemical Application Efficacy

    New

    This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in the 2024-2025 growing season. Management of diseases is necessary to protect crops against disease pathogens and reduce their spread in vegetable fields. This study aims to detect Phytophthora blight severity, a major disease affecting pepper plants, using drone technologies. Contributing authors include county and regional faculty as well as specialists from UGA’s horticulture, plant pathology, crop and soil sciences, and entomology departments. All research has been supported by the Georgia Commodity Commission for Vegetables.

    Drip Fertilizer Schedule Recommendations for Vegetable Crops in Georgia Coastal Plain Soils

    A soil test is a chemical technique used to determine the status of available nutrients in a soil sample. It is a common method used to predict how soils will react to the addition of lime or fertilizer and calculate how much of each is required for crop production.

    What’s Wrong with My Pepper? Common Defects of Bell Peppers Explained

    Various physiological disorders can affect the appearance and desirability of fresh market bell peppers; these often arise from environmental stresses and nutritional imbalances. Understanding these physiological issues is essential for growers to manage and mitigate them effectively. These disorders are common and are related to plant growth and development, not diseases. This circular shows these horticultural characteristics or traits that are expressed by certain genotypes.
