PMN Would Like to Hear from You!
To better serve you, PMN is evaluating the resources it offers. A link to a survey was sent in an email from Scientific Societies on Wednesday, October 10, at about 12:40 p.m. Central Standard Time. Please check your email for the survey, and if you havenít already responded, please do. Completing the survey takes 1 minute, and your identity will be kept confidential.
 
Focus on Potato
 
The unpredictability of weather and the crop injuries it causes are a constant concern for growers. Injuries caused by hail are particularly troublesome because of the reductions they can cause in marketable yield. Harlene Hatterman-Valenti reviews the factors related to yield loss, including the cultivar grown, the seriousness of the hail storm, and the stage of plant growth when the hail storm occurs.
 
Focus on Cotton
 
One of the most difficult decisions to make in a growing season is whether to accept or replant a cotton stand. Sean Butler summarizes factors to consider when first evaluating an emerged cotton stand and when managing a replanted field, along with advancements that may improve replant decision making and yield potential.
 
 
 
 
What are the effects of reducing carrier volume and using coarse spray tips compared with traditional practices of applying harvest aids? James A. Griffin provides information that will help farmers make decisions about which nozzle tips and water volumes to use to apply harvest aids and how pressure, volumes, and tips affect spray patterns.
