Aspergillus crown rot disease is on the rise in Georgia peanut fields and University of Georgia researchers are working to pinpoint why. At present, university scientists recommend that farmers encountering this problem in their fields stop saving seed from year to year in an effort to reduce the disease while better control methods are found. The first line of defense has been fungicide application either in furrow or directly to the seed.

Nematode control is one of the costliest hurdles to blueberry production on replanted sites. Through research trials in Appling County, Georgia, University of Georgia Cooperative Extension Agriculture and Natural Resources Agent Shane Curry found that adding pine bark mulch when replanting blueberry fields helps to combat the pests.

Summer may have ended, but Georgia’s silverleaf whitefly infestation has not.
