Leaf Spot In A Dry Year

Increased presence of disease shows susceptibility of varieties and weakening of fungicides. Georgia peanut growers experienced problematic leaf spot diseases this year because of susceptible varieties and weakening fungicide treatments, according to Albert Culbreath and Tim Brenneman, plant pathologists at the University of Georgia Tifton Campus. Brenneman says this year’s dry conditions should have set up an environment that was ... 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 »
