There are plenty of new, proven crop protection products out there — all of which come with yield advantages, improved return on investment, increased efficiencies, more flexibility and so on. So how do you decide which new products are worth recommending?
“It’s beneficial for farmers and retailers to conduct their own evaluations to determine how products perform with their specific combination of management factors — including soil, pests, crop genetics and climate conditions,” says Mike Moechnig, field scientist, Corteva Agriscience. “In addition to product performance, it’s also useful to know if the product’s storage and handling characteristics are compatible with your management program and equipment.”
New products are thoroughly tested to verify a base level of performance, crop safety and compatibility with equipment. However, it’s impossible to account for all scenarios. This is where on-farm test plots come into play.
Replication of product performance with test plots will help ensure the results your customers are seeing are not just an anomaly and provide an expectation for a crop’s response range.
“While farmers are often most interested in simply seeing if a product can provide an improvement, they also need to ensure some level of confidence in those results,” Moechnig says. “Replication is the primary means of developing some probability that those results would be repeatable and thus provide confidence in the conclusions.”
Test plot replication can be achieved with:
“Make sure there is only one differing factor between treatments so you can have confidence that the factor was most likely responsible for the result,” Moechnig says. “You also want to ensure that there is a fair comparison between treatments by ensuring field conditions are similar — and that products are being applied properly.”
Jeremy Stock, a retailer in Illinois, used test plots to evaluate the performance of Utrisha® N. This biological product naturally improves plant vitality by fixing nitrogen from the atmosphere and converting it to ammonium.
“I’m not the type just to throw a product on every acre. I like to leave check strips,” Stock says. “We did every other pass, so we got not just one check — we got multiple checks through that field to see if we just picked one good spot or if, overall, we saw the same outcome with every check strip.”

Recent input costs have incentivized many farmers and retailers to look for ways to maximize the crop growth response to fertilizer inputs and, ultimately, get more yield per acre of land.
“Nitrogen stabilizers and biologicals can both be used to make fertilizers more efficient,” Moechnig says. “It may be worthwhile to explore the effect these types of products can have on customers’ fertility programs.”
Keep in mind that using any new product or management system will require some learning and potential adaptations in management practices.
“Although most nitrogen stabilizers and biologicals are relatively easy to use, there can be limitations on tank-mix options, equipment needs — and there will be some time needed to develop an understanding of the conditions that allow for the best return on investment,” Moechnig says.
