Statewide Slug Monitoring Project – Update # 6

Figure 1. Slug feeding on soybean cotyledon in the field.

Our sixth slug update covers monitoring from June 16th to June 22nd. During this time, we had 12 counties monitoring a total of 96 shingle traps. Slug populations seem to be finally recovering from the cold weather early in the season, as their numbers are up this week. The highest average slug count in a county was 8 (up from 3 last week), which was an outlier from the statewide average of 1.44 slugs per trap. We will continue to update slug numbers as the season continues, so stay tuned for slug updates over the next few weeks! Slug shingle monitoring in Ohio is funded by the United Soybean Board.
