Plant-Parasitic Nematodes Complicate Crop Quality
By Johan Desaeger The importance of plant-parasitic nematodes (PPN) in agriculture was first demonstrated in the mid-1800s with the discovery of sugar beet cyst nematodes in Europe and root-knot nematodes in Europe and the Americas. Experiments with nematicides in the early-mid 1900s demonstrated the significant yield loss caused by these nematodes. Yet to this day, PPN’s true impact on crop …

Using Artificial Intelligence to Assess Storm Damage
University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researchers are using artificial intelligence (AI) technology to quantify damage to fruits and vegetables caused by extreme weather events, such as Hurricane Ian in 2022. When Ian struck on Sept. 28, it brought winds up to 155 mph and caused as much as $1.56 billion in damage to crops, livestock and …

UF/IFAS Extension Agent: We Need to Manage Fertilizer More Efficiently
By Clint Thompson North Florida watermelon producers should be wary about the dangers of applying too much water. It can result in leeching of nitrogen in their sandy soils. Producers who apply too much water not only lose the excess water, but they also lose the fertilizer and then yields. Mark Warren, University of Florida Institute of Food and Agricultural …
Correct Disease Diagnosis Crucial for Producers
By Clint Thompson An incorrect diagnosis of a plant disease can be a costly error for a producer. In an era where input prices are just as high as they have ever been, a farmer can ill-afford to apply the wrong fungicide. Gary Vallad, professor of plant pathology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) …
