NICHOLAS SEITER UPDATES
I remain concerned about spider mites in areas which are under drought stress; I received a report this morning about mite problems in White County. Hopefully the rains this past week have slowed them down, but stay vigilant in areas under drought stress. Corn rootworm adult emergence should be well under way throughout the state. As most of the rootworm adults will still be in the field they emerged from, this is a good time to inspect fields to get a feel for the extent of your rootworm problem and how your traits/insecticides are performing. If you have high adult emergence, consider digging some roots to assess the extent of larval damage.
Speaking of damage, we learned how corn rootworm emergence tents hold up to an 85-mph derecho; not well, as it turns out. However, it was probably worth the damage to get some healing rains.
