Western bean cutworm activity in Kansas
Western bean cutworms are primarily a pest of corn in Kansas and activity is generally isolated to the western part of the state. Early detection of egg masses is important, as any chemical control needs to happen before larvae enter corn ears. When the field is almost fully tasseled, an average of 8% of plants with eggs or small caterpillars justify control measures.
Have problems with Sudden Death Syndrome in soybeans?
Can you help? We are in search of grower fields with symptomatic Sudden Death Syndrome (SDS) plants for us to sample. Root symptoms include necrosis and above-ground symptoms include interveinal leaf chlorosis and necrosis. Under the right environmental conditions, these symptoms appear as early as the start of flowering.
