If herbicides are applied with deer repellents, what do you think happens?

🟢They improve crop protection.
🟢They interfere with w**d control.
🟢They make no difference.

Dr. Kevin Bradley, Dr. Bob Pierce and Grady Rogers put these questions to the test in a new University of Missouri study. The team conducted field trials for two growing seasons in soybean fields near Bradford Research Center.

Find out which prediction is correct, and the implications for deer browsing and growers in the field.

Deer repellents don’t typically alter herbicide effectiveness or crop yields when tank-mixed with herbicides, but the repellents also don’t consistently limit deer feeding. Learn more about this University of Missouri research in this article.

We're having a joint meeting this year in collaboration with Missouri Soybeans. Our "normal" Crop and Pest Management Field will be held the morning of July 8 at the Bradford Research Center and then we will be having an Ag Innovation Field Day next door at the Farm for Soy Innovation.

W**ds like Palmer amaranth and waterhemp have a new means of spreading: commercially-available wildflower and bird seed. Learn more about how w**ds spread through store-bought seed in this article.
