Evaluate Peanut Fields for Disease and Nematode Control
Posted by romeethredge on September 22, 2011
Now is a good time to evaluate disease control in our peanut fields. This was a serious White Mold (sclerotium rolfsii) year for us and so it will show up if your control program was less than what you needed or the timing was off. White mold came in early this year. Here is a field that recieved too few fungicide applications too late in the year and white mold was a yield reducing problem.
Dr. Bob Kemerait, UGA Extension Plant pathologist says that, “Now is an EXCELLENT time for growers to identify areas in their peanut fields where nematodes are a problem. This is best done by locating areas of poor growth and then looking at the roots, pegs, and pods for galling. Nematode samples can be collected and sent to the UGA Lab in Athens for further confirmation of the scope of the problem.” If you want to take a nematode sample you should take it in the root zone if possible and keep the sample cool and moist until we can get it to the lab for analysis.
Here’s a video I took this week of some good irrigated peanuts being dug.
