Summary: Two separate research trials were performed by NC State Extension using Xyway LFR fungicide in the Piedmont of North Carolina in 2021. One trial was on silage and the other on grain corn. The use of Xyway LFR had neither a positive nor a negative effect on crop yield. 2021 was a dry year and disease pressure was minimal. These trials should be repeated in higher pressure years to reveal more information about Xyway performance under different conditions. There were no long-term negative effects on silage yield from using Xyway LFR at planting.

Silage Trial: This replicated trial was planted at the N.C. Department of Agriculture and Consumer Services Piedmont Research Station in Salisbury, NC on April 29, 2021, in a Lloyd clay loam with a no-till planter. Starter fertilizer (10-27-0) was used in both control and Xyway treated plots at a rate of 10 gallons/acre in-furrow. The variety planted was AgVenture AV3917YHB and is a dual-use 117-day variety. Seeding rate was 32,000 seeds/acre. Harvest was on August 12, 2021. Samples were sent to DairyOne for NDFD 30-hour and mycotoxin analysis. For the 30-hour analysis they measured forage quality for crude protein (CP), neutral detergent fiber (NDF) and dry matter (DM). This resulted in no significant differences between the treatments. No mycotoxins were seen in any of the samples.
