Dicamba Injury & Seed Quality Concerns
Tom Barber's article Dicamba Effects on Soybean Seed and Off-spring is a must read for seed producers. According to Barber's article "The interesting observation in regards to dicamba symptomology on soybean plants is that foliar symptoms are not apparent much past R3 or R4. In other words the dicamba in the plant is no longer being transported to the soybean leaves, but rather is all moving to the sink on the plant, which includes the pods and developing seed." The article concludes with "The fact that late applications of dicamba can have an effect on seed quality the following season, seed producers should monitor production fields closely for late season dicamba symptomology on soybean pods."
Illinois Crop uses a "bean rake" constructed of dowel rods to push plants over during flower color inspections on Foundation soybeans. It is a homemade easy to make device that can be used to check pod development on fields where damage is suspected. It may also be time for producers to have additional acres inspected for purity prior to harvest. Before harvest be sure to consider the possible consequences of placing affected and unaffected fields of the same variety in a common bin.
While information on the effects of dicamba damage on seed is incomplete Illinois Crop Improvement stands ready to be your partner in quality testing and growout services.
Palmer Amaranth Testing
Pat Tranel and graduate student Brent Murphy, University of Illinois, have developed a way to identify Palmer amaranth DNA from within a mixed seed sample without having to grow the plants or test individual amaranth seeds. See how this powerful new tool can help you assess your samples for noxious weed seed by reading more on our news page. Samples for purity can be submitted to the Illinois Crop Improvement Association for separation of the pigweed seeds. Alternatively, previously separated pigweed seed samples can be submitted directly to the U of I Extension's Plant Clinic.
Soybean Deadline August 1st
Soybean pre-harvest field inspection applications for Illinois are due August 1st. Foundation or parent field inspections were due July 1st. A timely application means a timely field inspection. To certify crops, Illinois Crop must inspect the field at the proper life stage or maturity stage of the crop. Late applications can also cause you to miss out on being listed in the directory. The Grower's Directory is a marketing and advertising opportunity that you should take advantage of. Your authentication fee and acrerage charges go farther when you are being listed in both the on-line and print versions of our publications.
