Corn earworm alert! By C. Welty

A large population of corn earworm moths is now active in some parts of Ohio as detected by our pheromone trap cooperators. In Columbus, there were 141 moths in a trap on 8/21 but only 86 on 8/24. Near Springfield in Clark County, 179 moths were in a  trap between 8/17 and 8/24. Sweet corn that is silking should be sprayed on a 3-day schedule when earworm pressure is this high. More details about spray schedules relative to trap catch and temperature are found on page 258 of the Ohio Veg Production Guide (online at http://ohioline.osu.edu/b672/).

Pumpkin Self-Directed Field Day at Western Agricultural Research Station – Jim Jasinski, Bob Precheur

The OSU Extension Vegetable Team wants to invite growers to attend a self-directed field day at the Western Ag Research Station in South Charleston on Tuesday, September 1, from 3-7 PM. Growers can stop in or leave any time during the four hour window to talk to state vegetable specialists from the departments of Entomology, Plant Pathology, Horticulture and Crop Science, Piketon Research Station, and the IPM Program about disease, insect, and weed management or general horticulture, pollination, micro irrigation, fertility, and variety selection questions. Growers are encouraged to bring plant and fruit samples for the specialists to diagnose, and maps will be provided so growers can walk around the variety and research plots.

Signs will be used to direct growers to the plots where the specialists will be waiting under a tent or at a table to answer any crop production or pest management questions. This should allow growers to get individual questions answered during a four hour window.

There will be a several small presentations by the specialists only from 5-6 PM out in the field which will cover current topics in disease, insect, and weed management, or other key topics.

There will be no pre-registration for this event, no charge for attending, and no CCA or PAT credits offered. Refreshments (water and soft drinks) will be on hand. In case of rain, we will have the field day in the conference room at the new main building on the research station. The research station is located on S.R. 41 between South Charleston and I-70; complete directions to WARS including a map can be found online at http://oardc.osu.edu/branches/branchinfo.asp?id=9.
