I spent some time at Farm Fest today. The number of people attending seemed to be high today, although it was not too difficult to navigate throughout the grounds.
My report on soybean aphids is not changing. As of today, levels are quite low but evenly spread throughout the area. The forecast of more pleasant weather will be of benefit to aphids. I expect that their numbers will climb in the next week.
Spider mites are becoming more of a concern. There are a few fields were I think treatment may be warranted. There are even a couple of corn fields that may soon need a treatment. If you do need to treat for mites, I would recommend staying with a chlorpyrifos product (lorsban, nufos, etc.) because the other products are simply not that effective on them. Also, since we are well into August, I question the value of the name brand products and there guarantee. If you do spray this time of year, the chance that you will have to again is remote, making the extra cost of the guarantee worthless.
Have you looked at your corn? I mean really walked out into to it to see? The July heat was not good on it. The rows on the perimeter suffered from the heat, but think about how hot it got in the middle of the field. A number of fields that I did walk into had some pretty tough looking ears deep inside; some were not too bad. When the season is over I think we will notice some seeding rate issues. The picture is one taken from the field by my place from the middle of the field. This is a flex ear planted at a lower population and so far everything looks decent. The overlap area on the headlands where the population is higher does not look so good. This will be interesting to try to figure out.
