PECAN.jpegEditor’s Pick
In the article “Pecan Bacterial Leaf Scorch, Caused by Xylella fastidiosa, Is Endemic in Georgia Pecan Orchards,” Bock et al. report that 60% of the pecan trees they sampled in orchards in the southwestern and central production regions of Georgia were infected with pecan bacterial leaf scorch, caused by Xylella fastidiosa. —Pamela D. Roberts, Editor-in-Chief, Plant Health Progress

Focus on Soybean
Commercialization of new herbicide-resistant soybean technologies has increased the awareness that mitigating herbicide drift is important in ensuring the longevity of these tools. Travis Legleiter highlights application and environmental factors that influence the potential of herbicide drift and presents worst-case and best-case scenarios.

Focus on Potato
Health concerns over acrylamide, a suspected human carcinogen, in french fries, potato chips, and other processed potato products increase financial risks for practitioners across the potato industry. Paul Bethke addresses how acrylamide is formed, why potato products are relatively high in acrylamide, and how the potato industry can reduce the amount of acrylamide in processed potatoes. 

Focus on Cotton
Water quality can be both a regional and a local issue in the lower Mississippi River Basin, where 92% of U.S. agricultural exports are produced. Michelle Reba describes research by the Delta Water Management Research Unit using edge-of-field and in-stream water quality monitoring to better quantify nutrient and sediment loss at multiple scales. 
Historically, seed cotton modules have been identified using custom systems, but with the move to electronic data management and the potential for different manufacturers to provide prenumbered module covers or tags, a numbering standard is needed. Ed Barnes describes a standardized method of numbering cotton modules and the associated technology to facilitate automated tracking of seed cotton modules from the field through the module feeder at the gin.
Weed resistance to herbicides is increasingly problematic in Texas, particularly in the two major pigweed species: Palmer amaranth and waterhemp. Muthu Bagavathiannan and Peter Dotray discuss the distribution of resistance in these weed species to some of the historically important herbicides, such as glyphosate and atrazine, and the longevity of pigweed seeds in the soil seedbank after burial.
