The pros of injecting the antibiotic oxytetracycline (OTC) into citrus tree trunks to combat HLB appear to be numerous, including increased fruit yield, according to scientist Ute Albrecht. On the other hand, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) researcher only discussed one con, but it was a big one. “Trunk injections cause injury, and long-term effects need to …
Recent Rains Could Delay Fumigation Process
By Clint Thompson Persistent rainfall across the Southeast in recent weeks could delay fumigation progress from specialty crop farmers preparing to plant their fall crops. Tim Coolong, associate professor in the University of Georgia College of Agricultural and Environmental Sciences, discusses how heavy rain events could keep producers from getting into their fields at a key point in the season. …
Building a More Heat Tolerant Plant Starts with Genes
Scientists at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are looking for ways to help specialty crops beat the heat. A new study has identified genes that may help plants cope with stress from high temperatures. It could set the stage for developing crops bred for enhanced heat tolerance, said Bala Rathinasabapathi, senior author of the …
Ag Sector Likely to Support Economy Through Possible Recession
Though concern exists about impending recession in the U.S., the traditional economic indicators of recession aren’t yet apparent. This is especially true in the agricultural sector, says Georgia’s State Fiscal Economist Jeffrey Dorfman, a professor of agricultural and applied economics in the University of Georgia College of Agricultural and Environmental Sciences.   “The interesting question is, if I run a business …
Artificial Intelligence: Helps Detect Watermelon Disease Quickly, Accurately
The needs of Florida watermelon producers motivate Yiannis Ampatzidis to use artificial intelligence (AI) to detect pathogens early and accurately. One such disease, downy mildew, spreads like wildfire, said Ampatzidis, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) associate professor of agricultural and biological engineering. In newly published research, Ampatzidis used spectral reflectance — the energy a …
Insect Pests Top Concerns of Strawberry Producer Ahead of ’22 Crop
By Clint Thompson Strawberry planting season is still a couple of months away for Florida producers. One factor that is already on the mind of grower Dusty Grooms is the impact that two insect pests had in 2021 – chilli thrips and spider mites. The strawberry producer with Fancy Farms in Plant City, Florida, discussed the issue that plagued his …
Diamondback Moth Management: Insecticide Resistance Concerns Exist
By Clint Thompson Brassica growers rely almost entirely on insecticides to manage diamondback moth (DBM) infestations. However, the moths have shown the ability to develop resistance to a broad range of insecticides, says Hugh Smith, an associate professor of entomology and nematology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Gulf Coast Research and Education Center. …
Northeast Alabama: Rainfall Needed in Dry Region
By Clint Thompson Northeast Alabama is in dire need of rainfall. The region is abnormally dry, according to Thursday’s release of the U.S. Drought Monitor. Some areas are even moderately dry, especially along the Alabama-Tennessee state line. It is taking a toll on crops and ponds, says Eric Schavey, regional Extension agent in Northeast Alabama. “Right now, irrigation ponds are …
Resistance Concerns in Insecticide Management of DBM
By Clint Thompson Brassica growers rely almost entirely on insecticides to manage diamondback moth (DBM) infestations. However, the moths have shown the ability to develop resistance to a broad range of insecticides, says Hugh Smith, an associate professor of entomology and nematology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Gulf Coast Research and Education Center. …
Water and Soil pH Critical to Citrus Nutrition
There 17 essential elements that plants need to grow. Three of those elements come to plants via water and the atmosphere. The 14 other elements come from fertilizer applications. Almost all of those are dependent on soil pH to determine how well they are picked up by plants’ root systems. Getting the soil pH just right was discussed in the …
