I think we have some pretty decent crops in our area. The rains Saturday night were huge. There was a little wind but nothing major. It was not a good haymaking week, with a couple of little showers and poor drying conditions. I drilled alfalfa and orchard grass Saturday so the rain was huge for that. I think there’s some pretty good yield potential on corn in this area.
We received 1 inch of rain here on the farm this week. There were different amounts around the area though, and where there was little rain, the crop stress is getting more evident. The field work is pretty much done until harvest in our area. Most of the double-crop beans are beginning to bloom; they will have to hurry to beat the frost, I'm afraid. Enjoy what is left of summer!
Another week of summer temperatures in the 90s moved the crop along, trying to make up some of the season delay. Fungicide applications to soybeans are continuing. Yield checks on corn and soybeans seem premature with beans still setting pods and the potential for tip-back on corn still a concern. Storms brought heavy winds and rain, and some corn and soybeans leaned as a result. Weekly rainfall totals in a few isolated parts of the neighborhood were over 12 inches! The limited acres of sorghum in the area have already headed. It’s time to begin servicing equipment and preparing for harvest along with a quick trip to the Farm Progress Show to see the industry’s showcase.
Crops are hanging in there but are still in need of moisture. We have had a few scattered showers but only a quarter inch here and there. The disease pressure is fairly low on both corn and soybeans currently. In the corn hybrids that are more susceptible to gray leaf spot, it’s showing up, especially if they were not sprayed with a fungicide. In the no-till/strip-till corn-on-corn environments, anthracnose can be found. We will need to monitor the growth of the disease pressure, which might move the harvest date up a little bit.
We were blessed with 1.9 inches of rain last week — 1.7 of that came yesterday while in church. (I must have put enough in the collection.) The corn was starting to abort kernels before the rain, so this will slow that down and speed up kernel development. June-planted beans will grow now and hopefully set pods. With only 10 days left in August we are running out of time. I sure hope we stay warm through September. Waterhemp is showing up in some fields, and this rain will bring that problem on even more. There is quite a bit of corn borer in conventional corn. The traited corn is clean. We have a chance of rain tomorrow again up this way, we definitely could use more to keep crop progress going as fast as possible.
Now is a great time to scout for Palmer amaranth in Iowa crop fields.
As of late 2018, this species had been identified in over half of Iowa’s 99 counties. While new identifications have waned since the widespread introductions in 2016, Palmer amaranth is a species to watch out for in virtually any Iowa crop field.
WAUKESHA, Wis. — Soybean cyst nematode (SCN) causes the most yield loss of any soybean pathogen in North America, with economic impact in excess of $1 billion per year. That’s why soybean breeders funded by the checkoff are trying to improve and add to current genetic sources of SCN resistance and breeding them into high-yielding backgrounds.
