Corn and soybean in NW MN need rain.

Just how dry is it? Northwestern Minnesota has been dry over the last month, with large areas accumulating between 1 and 3 inches less rain than the 30-year average (Figure 1).

Spider Mite Activity in the Region

Reports of spider mites in soybean fields are trickling in from the NW MN and other areas. Personal observations have found mites on field margins in areas where recent showers have missed or dropped negligible precipitation. Some of these northern fields are advancing quickly through the R5 growth stage. Areas where rains have occurred are less likely to have mites building on field margins.

Scouting and managementA magnifying lens can be useful for seeing this small-sized pest. Risk of infestation is greatest under drought conditions. Since infestations are typically first noticed in field edges, initial scouting can focus on these areas; particularly edges near alfalfa, grassy ditches and other perennial vegetation.


ScoutingBeginning at the edge of the field, examine the undersides of leaves to determine if twospotted spider mites and/or webbing are present. If present, move farther into the field and examine two plants at each of twenty locations spread throughout the field.
