Corn and soybeans are looking good for the most part, but a good rainfall is needed, says Joe Rickard, WinField agronomist. Southern Ohio recently received rain, but the northern part of the state remains dry.
Corn plants are anywhere from V8 to VT, and soybeans are between V6 and R1. There is a wide range in crop growth stages this year because a cold, wet spring delayed planting until mid-May in much of the state.
There haven’t been any unusual insect outbreaks, through Japanese beetles are beginning to appear in certain areas, Rickard reports. Corn and soybean diseases are also not evident currently, but that could change toward the middle or end of July. Farmers should be prepared if disease, insect or weed pressures do appear. Performing proactive scouting to detect issues early and making timely applications of any needed crop protection products is a smart strategy, he notes.
This year’s dry weather has made it easy for farmers to get into fields to make plant health applications, whether that means micronutrients, fungicides or an additional shot of nitrogen, says Rickard. There is still lots of time to get the best yield potential out of corn and soybean crops in 2016.

After a cold, wet spring, farmers have made good progress and are finished planting both corn and soybeans, reports Joe Rickard, WinField agronomist. There are very few fields that still need to be planted. Emergence has been good, with some replants throughout the state. Growth stages for corn are varied, with some earlier-planted corn in the V6 to V8 range and fields planted later more in the V3 to V4 range. Rickard says that crops look very good for the most part around Ohio; however, after a dry stretch, farmers would welcome a good rainfall.
Rickard reports seeing numerous zinc deficiencies in early-growing corn crops, and they are very visible in the field. He has only seen a couple of tissue samples in corn, but these are indicating deficient to responsive results with zinc, manganese and boron. At this point, he has not seen any nutrient deficiencies in soybeans.
Rickard recommends growers take tissue samples between V4 and V6 in both corn and soybeans to find out what nutrients they need and to determine what products to use to address issues. It’s essential to begin monitoring plant nutrition early, because once farmers start seeing evidence of deficiencies in the field, yield has already been affected.
The current dry weather has caused weed outbreaks in some fields that were treated with a preemergence herbicide in late May. It will be critical to control weeds, along with keeping nutrition on track during early postemergence for both corn and soybeans, says Rickard.

Farmers are still planting corn and soybeans in Ohio, reports Joe Rickard, WinField agronomist. There was a two-week window at the end of April that was favorable for planting corn, but once that window closed, good weather to get spraying and more planting done has been spotty. May’s cold, wet weather is hampering soybean progress, too, with only 20 to 30 percent of soybeans in the ground.
The southwestern corner of the state was able to get corn crops in during the latter part of April, Rickard says, but other parts of the state have not gotten much corn planted. Walking fields in mid-May, Rickard saw V2 to V3 stage plants pretty consistently. The corn that has been planted is looking very good — even though there was a mid-May frost in northern Ohio.
Giant ragweed has been poking up in parts of some Ohio cornfields. Marestail continues to be a huge problem in soybean fields. Many farmers are looking at the calendar and wanting to take the 2,4-D out of their burndown mix. Rickard has been advocating for leaving it in, but growers want to get the crop in the ground and have had to shift to different chemistries, he says.
The wet weather has also been very conducive to slugs, which have been found in some fields. Rickard says he will be on the lookout for black cutworm in the upcoming weeks, too.
