This weed’s ability to survive goes beyond its penchant for developing resistance to herbicides. By Ramon Leon, Extension Weed Specialist, West Florida REC, and Jay Ferrell, Extension Weed Specialist, Agronomy Department, University of Florida Palmer amaranth, commonly referred to as Palmer...

Be critical about fungicide selection, timing and ability to move down the plant in what could be a year of increased disease.  By Amanda Huber The first line of defense in disease management in peanuts is crop rotation. However, the...

Peanut growers are fortunate to have 18 active ingredients registered for use as herbicides. In general, these herbicides are very effective when applied at the appropriate rate and time. Failure to start clean at planting, residual herbicides that are...

Regrowth of winter host plants create a haven for disease pathogens and nematode populations. A La Niña weather pattern is providing warmer winter temperatures for Georgia residents, sparking farmers’ concerns about potential plant diseases at the start of production season...

Insect populations fluctuate greatly with temperature and moisture. Year 2016 was an interesting one that started with a very wet spring followed by a drought starting in June with a dramatic reduction in precipitation that lasted five months. Looking at...

In 2016, losses to tomato spotted wilt across the peanut production region of the Southeastern United States increased slightly compared to losses from 2015. Losses associated with spotted wilt were approximately 3 percent in 2015 and 3.5 percent in...

Drought leaves producers facing difficult decisions on dryland fields.  Weather conditions deteriorated during the latter part of the summer in Georgia and little rainfall was recorded at critical stages of the growing season. Scott Monfort, University of Georgia Extension peanut...

By Peter Dotray and James Grichar, Texas A&M AgriLife Research Preplant and preemergence herbicides have likely done what they can, and new weed flushes are starting to emerge. Herbicides applied early postemergence that do not have soil activity may give...

The European Food Safety Authority’s review of older products, such as propiconazole, found a lack of sufficient residue data in peanuts, other crops. What happens now? By Alan Henn, Extension Plant Pathologist, Mississippi State University Most peanut growers have received notification from...

While work continues on developing economic thresholds for insect pests, scouting can pay dividends now. University of Georgia entomologist Mark Abney is searching for ways to monitor insects responsible for destroying peanut crops, a first step in developing economic thresholds...

Florida Pusley (Richardia scabra) Florida pusley is a low-growing, annual weed species that appears almost prostrate. It can be effectively controlled only with pre-plant incorporated herbicides. Florida pusley has bright green leaves with a distinctive recessed mid-vein. The stems are very...

By Mark Abney, University of Georgia Extension Entomologist Insect and mite pressure in peanut can vary dramatically from year to year and even from field to field within a year. Each growing season brings with it new challenges; growers in...

In 2015, losses to tomato spotted wilt across the Southeastern production region stabilized and were similar to estimated losses from 2014 at three percent, although it was more severe in some fields than in others. Growers can achieve excellent management...
