University of Minnesota researchers have developed a variety of conventional aphid-resistant soy (Aphis glycines). According to the project's main researcher, Dr. Bob Koch, the goal is to reach a seed that reduces the use of insecticides in a natural way.

“Research from Minnesota and other states shows that these varieties can be very effective in protecting soybean plants - protecting their production, preventing the growth of aphid populations. But the challenge is that they are not widely available, ”said Koch.

Another element of his research is the use of remote sensing technologies to help farmers visualize where infestations are in their fields. Using satellite data, the researchers were able to detect harmful levels of aphids. Farmers can then use this data to determine which crops would benefit from the treatment and which would not.



Koch said this will be an important tool for farmers who are applying insecticide to their fields. Knowing which areas need the insecticide reduces the tendency to cover the field with insecticides and helps farmers to opt for a more targeted application, which can also save money.

"Availability now with aphid-resistant soy, especially in northern Minnesota and central Minnesota is very, very limited," said Lorenz. "In general, large seed companies don't really develop aphid-resistant soy ... so my philosophy is that the more we develop, the better off we are in terms of options for farmers," said Aaron Lorenz University professor and researcher.
