1. Evaluation of Utilization Potential for Methods of Georeference in the Management of Weed Contamination of Potato CulturesCombating crop contamination with harmful invasive species is one of the main themes of agricultural research. For the potato cultures, the weed contamination decreases not only the quality but also the quantity of the harvest. The most invasive contamination for this culture is represented by the Agropyron repens and Sorgum halepense, two invasive and very nocive species characterized by underground stems able to penetrate the potato¢s tubercle and decrease their storage...

2. Decision Support Tools for Developing Aflatoxin Risk Maps in Peanut FieldsAspergillus flavus and Aspergillus parasiticus hereafter referred to jointly as A. flavus, are soil fungi that infect and contaminate preharvest and postharvest peanuts with the carcinogenic secondary metabolite aflatoxin. A. flavus can cause extensive economic losses to peanut growers and shellers by contaminating peanut kernels with aflatoxins. In the southeastern U.S., contamination from aflatoxin continues to be a major threat to the peanut industry and... G. Vellidis, M. Abney, T. Burlai, J. Fountain, R.C. Kemerait, S. Kukal, L.

3. Field Mapping for Aflatoxin Assessment in Peanut Crops Using Thermal ImageryAflatoxin is a toxic carcinogenic compound produced by certain species of Aspergillus fungi, which has a significant impact on peanut production. Aflatoxin levels above a certain threshold (20 ppb in the USA and 4 ppb in Europe) make peanuts unsuitable for export, resulting in significant financial losses for farmers and traders. Unmanned Aerial Vehicles (UAVs) are becoming increasingly popular for remote sensing applications in agriculture. Leveraging this advancement, UAV-based thermal imaging... S. Shrestha, L. Lacerda, G.

4. A Decision Support Tool for Developing Aflatoxin Risk Maps in Peanut FieldsAspergillus flavus (A. flavus) is a soil fungus that contaminates preharvest peanuts (Arachis hypogea) with the carcinogenic secondary metabolite aflatoxin. Because aflatoxin can cause serious illness or death at low concentrations (μg kg-1 to mg kg-1), its presence in foods and feeds is strictly regulated by food safety agencies around the world. Based on previous research by the authors, a hypothesis was developed that aflatoxin contamination... G. Vellidis, S. Maktabi, K. Boote, G. Hoogenboom, L. Lacerda, C. Pilcon, S. Shrestha, R.

5. Optimal Hyperspectral Band Selection for UAV-Based Aflatoxin Risk Prediction in Peanut FieldSouth Georgia’s humid subtropical climate and well-drained sandy soils make Georgia the leading peanut (Arachis hypogaea L.) producing region in the United States, accounting for more than half of the nation's production. However, aflatoxin contamination caused by Aspergillus fungi remains a significant concern, posing serious food safety risks and causing substantial economic losses. Rising temperatures and humidity from the climate crisis create ideal conditions for fungi,... N. Niva, L. Lacerda, G. Vellidis, S. Maktabi, M. Ardigueri |
