When In Drought, Don’t Forget To Scout

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 climate data from Clanton, Ala., as an example of what happened last year, after the last big rain event in ... Read More »

Crop Recap: Weather Weary Year

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 specialist, estimates that as much as one-third of Georgia’s dryland crop has produced very little. So little, in fact, that ... Read More »

From Here To Harvest

Planting conditions support the thought that the crop will be slightly less than last year. By Amanda Huber Early reports of the 2016 crop are good, but a lack of uniform emergence caused by cooler weather conditions will likely cause problems later in the season. Without the ability for a “do over” of planting to get a more uniform stand, ... Read More »

Seed Treatment Resistance In Thrips

University of Florida researchers study the resistance of tobacco thrips to  neonicotinoid seed treatments; additional insecticide applications may be needed. By Danielle Sprague and Joe Funderburk, North Florida REC, University of Florida, IFAS Tobacco thrips, Frankliniella fusca, are seedling pests of peanut, soybean and cotton throughout the southern United States. Adults and larvae feed on the developing leaves, causing injury ... Read More »

Protecting Profit from Pests

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 that will indicate when it’s time to apply insecticide products. Currently, Abney and his team are focusing on the three-cornered ... Read More »

Virginia Crop: A Mixed Bag

  Be sure moisture can’t get back into stored peanuts and create conditions for mold growth. Editor’s Note: Splits and sprouting are two words no producer wants to hear in relation to a peanut crop. But according to Maria Balota, associate professor of crop physiology from the Virginia Tech Tidewater AREC, 2015 was a most unusual year in Virginia. Her ... Read More »

Consider Scouting Your Peanuts In 2016

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 the Southeast will not soon forget the lesser cornstalk borer and two spotted spider mite outbreaks that accompanied hot, dry ...

What’s Under That Canopy?

More scouting of fields is needed for effective insect management. By Amanda Huber With insect management in peanuts, there are a lot of “if, then” contingencies. If it is hot and dry, then expect to see more lesser cornstalk borer. If you use a pyrethroid in a field where two-spotted spider mite is present, then it usually makes the spider ... Read More »

Spraying By The Numbers

Use information on pesticide labels to rotate herbicide ‘families.’ Herbicides are grouped according to family, such as triazines, and by the target site of action or mechanism of action, such as acetolactate synthase or ALS inhibitors. Herbicides within a family have similar chemical structures and, typically, the same site or mechanism of action (MOA). Knowing the chemical family and MOA ... Read More »
