Soybean Loopers and the Effect of Defoliation on Yield Loss

Soybean Loopers and the Effect of Defoliation on Yield Loss

🕔12:43, 2.Aug 2015

We have been getting calls on loopers showing up in soybean for about 2 weeks. In recent days there have been reports of defoliation exceeding 20% or numbers exceeding threshold in some areas in the central to southern part of the state. The bulk of our soybean loopers typically show mid to late August or even into September so this is a little early but certainly not unusual. Soybean loopers are migratory and work their way north each year from southern latitudes. Early arrival could be due to a number of reasons.

Diagnosing Fungicide Phytotoxicity and Telling Apart from Root Diseases

Diagnosing Fungicide Phytotoxicity and Telling Apart from Root Diseases

🕔09:32, 22.Jul 2015

Phytotoxicity as the result of applying fungicides that contain an active ingredient that produces an “injury” to soybean leaves has been observed this year. Large areas of fields or entire fields in an area with observable interveinal chlorosis should be observed for the presence of a specific disease. Observing root systems as well as cutting into the main stem to expose the vascular tissue should help tell the difference between many soybean root diseases and whether or not a disease is present.
