March is a month where I spend some time planning on-farm research and other experiments. One topic that surfaced during our on-farm research meetings in February was potentially testing the fungicide product Xyway™. This product is unique in that it is applied in furrow and can be applied with starter fertilizer at planting. It moves systemically in the plant through the water carrying vessels (xylem). For growers who are near towns or locations where aerial applications are restricted, a product like this is intriguing and could have a unique fit.
There’s limited university research with the product, but the findings have been intriguing thus far. The LFR® and 3D versions (in furrow at planting) were tested in Kentucky compared to untreated check and foliar fungicide products (Lucento® and Headline AMP®) applied at R1 in corn. In 2019, Xyway™ LFR® and sometimes the 3D version also showed the same efficacy for northern corn leaf blight (NCLB) and even gray leaf spot (GLS) compared to products applied at R1. All the products had less disease severity compared to the untreated check. Xyway™ did not reduce southern rust disease severity. In 2020, low disease pressure in general was observed in the Kentucky locations. The Xyway™ still provided the same disease reduction to GLS as foliar products applied at R1, which were all significantly less than the check.
In 2020, Dr. Tamra Jackson-Ziems also had a study at UNL South Central Ag Lab near Clay Center. The study compared different application timings (at planting, R1 and R3) of different products compared to an untreated check. Xyway™ LFR® was applied with starter at 15.2 oz/ac at planting. This was compared to Xyway™ at planting + 5 oz/ac Lucento® applied at R1. A number of foliar fungicide products were applied at R1 and R3. The Xyway™ LFR® applied at planting showed no disease difference compared to the untreated check for southern rust. All the other products and timings reduced the amount of southern rust compared to the untreated check. Traditionally, we’ve seen fungicides provide improved standability. In 2020, there were no differences in lodging for any of the products or timings compared to the untreated check. Regarding yield, the Xyway™ LFR® at planting yielded better than the check, whereas there was no yield difference with the Xyway™ + Lucento® at R1. Looking at the data, there were no yield differences between applying foliar fungicide at R1 vs. R3 for any of the products except Miravis® Neo. And, sometimes a product didn’t show a difference between other products or even the untreated check. I show a picture of the data on my website jenreesources.com. With last year being a heavy southern rust year, being able to wait till R3 to apply a fungicide provided some additional time for the residual to work when southern really came on. I know some had to apply a second fungicide application when they automatically applied at R1; that’s just tough from an economic and resistance management perspective.
Because I’ve got nearly a handful of growers interested in testing Xyway™, I put together protocols at jenreesources.com if you’d also like to check them out. If you’re interested in testing any study via on-farm research, please contact me or your local Extension educator.
Solar energy webinars
These webinars are free and for anyone who is interested in solar. What is the payback for Solar PV systems? A common question with not such as easy answer. Farmers and businesses are receiving marketing materials to invest in solar, yet the economic feasibility of solar is not always clear. This webinar series will cover how solar electric systems work, how to determine the value of energy and how the complexity of subsidies and policy make general statements about feasibility more complex. This workshop will cover these issues in detail and provide participants with the information they need to speak confidently with farmers about solar electric systems. All webinars are held from 9 - 10:30 a.m. on March 30, April 1, April 6, April 8. Registration at: https://unl.zoom.us/meeting/register/tJEod-qhrz0sHdYkpW9nRnfdsv0wlk78bW99. Those with specific questions can reach out to John Hay, Nebraska Extension Educator at 402-472-0408 or email@example.com.
