Northeast Ohio Agronomic Crops Update

The dog days of summer have arrived and with it heat and dry weather. If you are wondering if it will ever rain again, you are not alone. Most of the farmers in the state of Ohio wondering the same thing. After what seemed like an eternity of wet weather we have now gone to the dry side. However, the crops are holding up quite well for the conditions. Corn is rolling in the afternoon but looks good in the mornings. That may be an indication that there is a good root system that is picking up moisture from the soil. Pollination will be late this year. The most critical weather period will be when the corn starts to tassel and silk. For most of the corn in Northeast Ohio that will be the first two weeks of August. Until then lets hope for rain and uniterrupted growth.

Soybeans are looking good, many are starting to flower. The only negitive is that they are short. You need to start scouting your beans for aphids and two-spotted spider mites. Mite damage is the most likely to occur due to the dry weather. Scout the outside edges of the fields, this is where damage occurs first. A few aphids have been spotted near Wooster. However, none have been found in Northeast Ohio at this time. We are expecting them to appear later in the season. Soybean diseases are minimal due to the hot dry weather. Ninty degree temperatures have all but shut down the disease organisms. This does not mean however that we will not experience some problems later on if the weather changes.

Wheat harvest has wrapped up and it appears that yields are average to below average, as expected. There were to many spots in the fields that drowned out for optimum production. Kernal size was small and the test weight was between 56 and 60 pounds per bushel. Head Scab could be found but at extremely low levels and no volmitoxin was reported. The lessons we learned this year were, that wheat needs to go on to tiled or well drained soils. Wet ground and wheat does not go together if you want maximum yields. Also you need to pay attention to the Head Scab Prediction Center forecast for Head Scab disease severity. For this area it was right on the money. Our wheat flowering was seven to ten days behind the rest of the state. The result was a decline in disease severity at flowering. The result was little difference in head scab severity between fields that recieved fungicide or did not recieve fungicide. However, the fields that were sprayed with fungicide for leaf disease showed less foliar and glum disease. That application of fungicide may have improved yields and test weights. The bottom line is that fungicide application in wheat usually pays off. Also if you are going to apply fungicide especially for head scab you need to be able to make that application in a timely manner. This may require owning your own equipment to do the job. Aerial application was not possible and most custom applicators were swamped with work. They simply could not get to every field in time.

Crop Progress Report.

Corn- Across Northeast Ohio corn maturity ranges from V-5 to Tasseling. Hopefully that is not occuring in the same field.

Soybeans: Maturity ranges from V-3 to R-1 and above. The biggest problem is soybean field is weed control. Weeds need to be controlled now or yield reduction will occur.

Wheat: Harvest is done or close to being done.

Oats; Are tunring and should be ready to harvest soon.

Forages. Still some first cutting to harvest and second cutting is underway. Be on the look out for leaf hopper damage in Alfalfa.
