Planted round up ready corn couple weeks ago. All corn is up around 8–12”. We have had loads of rain, o top of the field was speed with chicken litter before planting. So, the weeds & grass started to get out of control. Sprayed the corn this past Sunday (yesterday). Well today (Monday) it’s got brown dead looking spots on the leaves. Come to find out my buddy used RM18 a fast acting round up from tractor supply & Mixed sort of heavy. Do you guys think the corn will bounce back and be ok or will It continue to dye off? Used same corn last year & sprayed twice with 41% round up and didn’t do this. Thanks.
