Junior Fair 4-H, Farm Science Review, stink bug update
Junior Fair 4-H entries were due in our office yesterday for the Delaware County Fair which starts Sept. 15 and runs through Sept. 22. This is always a great time as we get to see all of the hard work that our county’s 4-H’ers have put in to their various projects over the past few months. So be sure to come to the fair and support our kids this year; go to some of the many Junior Fair livestock shows, go through the barns and the Junior Fair Building to see all the exhibits and much more.
I’m proud to announce our 2012 Agriculture Society Hall of Fame Winners: Tom Price and Earl Pool. Enshrinement in the Delaware County Agricultural Hall of Fame is the highest form of recognition in Delaware County for an individual who has made outstanding contributions to the agricultural industry. Each year up to two prominent agricultural leaders are honored and inducted into the hall of fame for their exemplary service, dedication, leadership and supportive contributions to agriculture and their support in Delaware County.
Tom Price has been very involved in promoting a positive view of agriculture and he has made many contributions in service to our community, one of them being his work to provide residents and businesses the opportunity to recycle organic materials and to produce the highest quality compost, soil and mulch. The late Earl Pool is honored because of the many contributions that he made through the years to further agriculture in Delaware County; many of these have been implemented into the Delaware County Agricultural Society today. Ethel Lehner of Radnor is Earl’s daughter. Tom and Earl will be honored at the fair at 11 a.m. Sept. 17 at the Ag Hall of Fame building. Everyone is invited to attend.
As we head into September, I want to remind you that the Farm Science Review is right around the corner. From Sept. 18 to 20 the review will mark it’s 50th year. The Farm Science Review will be held at Molly Caren Agricultural Center in London. Tickets are available for sale at the OSU Extension office for $5 in advance or $8 at the gate. Children 5 and under are free. The Review is sponsored by the College of Food, Agricultural, and Environmental Sciences, Ohio State University Extension, and the Ohio Agricultural Research and Development Center. It attracts more than 140,000 visitors from all over the country and Canada, who come for three days to peruse 4,000 product lines from 600 commercial exhibitors, and learn the latest in agricultural research, conservation, family and nutrition, gardening and landscape.
Stink Bugs in Soybeans
As you scout your fields be sure to be on the lookout for the brown marmorated stink bug, “Although we did not expect it to be a concern” said Ron Hammond, OSU Extension Specialist, Entomology, “that thought has changed somewhat over the past week in regards to this potential pest and the rest of the stink bug complex that occur in soybeans.” We have become aware of some soybean fields with much higher numbers of stink bugs than are normally seen, with some fields reaching a level that might need treatment. Hammond said that they have had reports of brown marmorated stink bug from a few fields. With support from the Ohio Soybean Council, scouting trips have confirmed brown marmorated stink bugs in soybean. So far only adults are being seen, but observations last year suggest that larger numbers of nymphs will start occurring within a few weeks. Hammond said that they we are also seeing greater numbers of the green stink bug and a smaller stink bug that is also green but with a reddish shoulder, this latter one is being called the red-shouldered stink bug. This is a new stink bug that has not been seen very much in Ohio. It is not the red banded stink bug that is causing bog concern in southern states, but it could be a potential problem and little is known about its damage potential. For the time being, we recommend grouping all stink bugs together for determining the need for treatment. Hammond said that through Ohio Soybean Council support, they will expand their sampling for stink bugs over the next few weeks across the state.
To sample for stink bugs, take multiple 10-sweep samples with a sweep net in multiple locations throughout the field. Average the number of stink bugs in the 10-sweep samples. The threshold to treat is four or more stink bugs, adults or nymphs. The threshold can be dropped to two or more stink bugs — if soybeans are being grown for seed. Pods should still be green. We would mention that we have already been in fields that meet this criterion. Because stink bugs often occur mainly on the field edges, especially next to woody areas, Hammond suggest sampling both field edges and within the field to determine which parts of the field might require treatment. See the soybean insect images page at tinyurl.com/cyy2po8 for pictures of the various stink bugs. The ones most likely to be in Ohio soybean fields include the brown marmorated stink bug, the green and red-shouldered stink bugs, the brown stink bug (with rounded shoulders) and the spined soldier beetle (with pointed shoulders), this last one actually being a beneficial predator.
