Alert Details

High corn rootworm risks continue across much of the corn-growing region this week as beetle activity is expected to persist in scattered locations. Fields from eastern Colorado into western and northern Kansas, Nebraska, eastern South and North Dakota, Minnesota, Iowa, northern Missouri, northern and central Illinois, Wisconsin, lower Michigan, northern Indiana and Ohio, and southern Ontario, Canada are all at continued risk especially in fields that are later planted or were re-planted. All growers should monitor beetle counts as high beetle numbers may signify that the field is prone to problems in 2015, and a change in planting practices/rotation and the need for treatment at planting may be needed. Risks are being reduced in the southwest portion of the corn-growing region as crops advance past critical growth stages and are no longer a threat from this particular insect for this growing season.
