Issue No. 16, Article 6/July 8, 2005
Regional ReportsNorthern Illinois
Scattered, isolated thunderstorms occurred throughout the region in the past 10 days, bringing some relief to the dry conditions. Moderate temperatures beginning over the weekend, coupled with rainfall, were most welcome, as corn is approaching tasselling. Soybeans that received precipitation have responded very well by continuing vegetative growth.
Reports of soybean aphids continue to be received, but the hot weather may have reduced population buildup. No reports have been received concerning insecticide treatment for soybean aphids. Spider mites are also present in some fields, with a few reports of fields being treated. Japanese beetles have been reported in soybeans, corn, and gardens, with some populations quite high. Growers are encouraged to monitor cornfields when silking occurs for potential silk clipping.
Numerous herbicide resprays have occurred in soybeans, particularly for lambsquarter control.
It rained on July 4th. Informal reports of amounts range from about .2 inch to over 2 inches. Obviously some growers are happier than others. Crops will be able to keep growing or at least survive.
Regular-season corn and soybeans are silking/flowering and are at critical developmental stages. Double-cropped soybeans should now have moisture to finish emerging.
There is still concern about dry-weather pests, as mentioned in previous issues.
Thanks for the rain; send more!
Upcoming field days: Belleville, July 13; Brownstown, July 28.
Hot and dry conditions prevail across the region. Rainfall on the 4th ranged from none to half an inch. Regardless of the amount, it was not enough to alleviate crop stress to any great degree.
Most cornfields have pollinated or are pollinating. Stress is showing on many of them, as some fields exhibit rolled leaves in the morning. Corn rootworm beetles are making their presence known throughout the area, in both first-year and continuous cornfields. On the east side of the region, many first-year cornfields are showing signs of root feeding and, now, adult beetles clipping silks. The western portion of the region is reporting heavy infestations of rootworm beetles in some continuous cornfields. Some scouts are counting upward of 20 to 40 beetles per plant in extreme cases. Aerial applications of beetle-control products are being made where necessary to protect what (little?) crop might be there. Where Japanese beetles have been reported, feeding is adding to the concern over pollination. Spider mites can be found throughout the area as well. Some control applications are being made.
Because of the poor growing season, many beans have not canopied over, yet they are blooming. A few soybean aphids can be found, although none have been reported at an economic level.
Wheat harvest has ended, with yield reports ranging from 50 to 80-plus bushels per acre. First- and second-cutting hay for most producers shows excellent quality, as there was no rain damage, but the quantity was down. However, third cutting is not growing (nor are most pastures) because of dry weather.
