The soybean cyst nematode (SCN) was first discovered in Iowa more than 35 years ago, in Winnebago County in 1978 to be specific. The nematode is widely considered to be the most damaging pathogen of soybeans in Iowa. Results of random surveys of the state funded by the soybean checkoff and conducted in the mid 1990s and again in the mid 2000s indicate that SCN is likely present in 75 percent or more of Iowa fields. SCN has the potential to...

This includes walking a field and stopping at multiple locations to look for symptoms. Of course with today’s UAV technology it is easier than ever to identify problem spots for the air and then you can walk right to that spot. However not on symptoms will be readily viewable from the air at a few hundred feet. When walking a field... |

June 04, 2015 Most soybeans got planted in May and even during the last week of the month with remnants being planted in early June. Frequent rains really put a dampener on planting in a timely manner. With the majority of soybeans planted growers need to assess soybean stands to determine if their crop is doing well or needs to be replanted. After soybeans emerge it’s time to do a little scouting to see how the stand looks, if emergence is even and... |

June 03, 2015 Bayer CropScience introduced this year its new ILeVO® seed treatment for soybeans. ILeVO is the first fungicide that will provide control of Sudden Death Syndrome (SDS). It is applied on the seed in combination with other fungicides, Poncho® insecticide and VOTiVO® that provides control of SCN. Bayer CropScience has been researching any potential interaction of our new SDS and nematode seed treatment ILeVO with pre-emergent herbicides... |
