Extension News: Good summer for crops in Ohio


Here in Central Ohio we’ve been pretty fortunate with rainfall. Our friends to the north/west and south are dry. The National Weather Service is reporting that the coming week the temperatures will remain near normal with the rain below normal. August is looking near normal and not as wet as what we’ve had. Crop conditions still vary, but overall it has been a good summer. Third cutting hay is getting closer and double crop bean are looking good.

There have been some reports of growers spotting a few soybean aphids in their fields. Finding aphids at this time of year is consistent in the past — we have seen them arrive later and later and there are a lot of late-planted soybeans that are in the R4 or R5 stage.

The economic threshold to treat soybean aphids is a rising population of 250 aphids per plant, But at higher growth stages (>R6) the threshold increases dramatically. At this point it is important to note that none of the fields in Ohio have reached treatable levels. According to Andy Michel, OSU Extension State Specialist, given the aphids’ arrival, the growth stage of soybean and the oncoming onslaught of natural enemies, it may be unlikely that we see any significant impact from soybean aphids this year, but we should monitor our fields. We’ve heard that insecticide resistant soybean aphids have been found out West (especially Minnesota and Iowa) but while we haven’t heard of any resistant aphids in Ohio as of yet — we certainly do not want to encourage their presence by applying insecticides when we don’t need to.

If you are planning on attending the The Farm Science Review this year — stop by our office and purchase your tickets. We will be selling them until Sept. 15 for $7; that is a $3 savings from the cost you will pay at the gate of $10. Children ages 5 and under are free. The Review is scheduled for Sept. 19 through the 21st at the Molly Caren Ag Center in London, Ohio. Show hours are 8 a.m. to 5 p.m. Sept 19-20 and 8 a.m. to 4 p.m. Sept. 21.

This is the 55th year and something new this year you can map your FSR show on a new mobile app in preparation for the three-day event. The app is available in app stores now. You will be able to browse the interactive map and search for specific exhibitors or product categories.

Every year offers so much to visitors with over 4,000 product lines exhibited by 630 exhibitors.

Educational presentations, demonstrations and displays are ongoing throughout the three days. Research tours on water quality, nutrient management and other topics in partnership with Ohio State and Beck’s Hybrids will be available.

Visitors seeking credits for Certified Crop Advisors (CCA) or pesticide application recertification should check the event schedule or watch for press releases in August and September.

Shuttle wagons will be leaving from the west end of the show site throughout the day to transport visitors to the Gwynne Conservation Area where there will be a focus on wildlife, woodland and aquatics educational opportunities, as well as a streambank protection installation.

Shuttle wagons will also take visitors to a variety of field demonstrations featuring different agronomic operations. Demonstrations include drainage installation, UAV’s (unmanned aerial vehicles), cornstalk baling and much more.
