While soybean cyst nematode can be managed through use of resistant varieties and crop rotation, presence of alternative weed hosts can negate the benefits of these practices by providing a host for soybean cyst nematode to continue to accumulate in the soil.
Before combining corn, it is recommended to scout your field for corn ear rots and stalk rots. It is important to scout corn fields for these two issues in order to make timely decisions on corn combining.
Have you noticed lower soybean yielding areas in your field? Soybean cyst nematode may be to blame. Fall, and especially after soybean harvest, is the best time to sample soil and have it tested for soybean cyst nematode.
The drought conditions in the past few weeks have led to some soybean fields senescing early. However, some of the early senescing may be due charcoal rot.
Several soybean fields scouted in a number of Eastern counties have plants dying or dropping leaves prematurely. While the majority of these fields have drought stress causing early senescence, a few fields have also stem canker developing
A few wheat fields scouted this summer were found with volunteer rye infested with ergot. Volunteer rye, in addition to being a weed, can be a source of ergot, which is a concern for winter wheat producers.
