| In 2022 we sprayed Veltyma at R1 and a second application of Revytek at R4 (5-10 kernels denting per ear) with only a 6 bushel/acre response on one hybrid and no difference on the other. Also did a second application of Delaro as late as half milkline with a 2 bushel/acre return. Another irrigated field sprayed twice and saw no visual difference and didn't show up on the yield monitor. Tar spot was pressure was moderate at ear leaf and below, but I think that year our corn outran the tar spot second sprays, or our second sprays were too late. | |
