Dr. Bob Kemerait:<\/p>\n\n\n\n

“1. Which growers are at highest risk?  Because the rust (which was well established in the field) was found in Coffee County, (and Colquitt Co as of yesterday, Thursday, 6\/10\/21<\/em>) I would say any corn in the southern Coastal Plain part of the state is at risk.<\/p>\n\n\n\n

2.  Should we recommend spraying? If corn has not reached VT tassel or is at R6 hard dough, do not spray. If the field has been sprayed in the last 2 weeks, don\u2019t spray. If the field is being SCOUTED and no southern rust is found, I wouldn\u2019t spray. That\u2019s why you pay a scout…. I would recommend spraying if 1) tassel stage or beyond, 2) irrigated with high yield potential, 3) especially in SE GA around Coffee-Jeff Davis Counties, AND 4) field is not carefully scouted.<\/p>\n\n\n\n

3.  Do we expect spread of the rust?  Yes! Weather is favorable and we have beaucoup corn this year in the state.<\/p>\n\n\n\n

4.  What to spray?  Single mode of action products like tebuconazole, tetraconazole, azoxystrobin and pyrscloztrobin are good products for about 2 weeks or so.  Mixed mode of action products are better and last longer. Are there \u201cbest\u201d products?  Yes, but NOTHING works once rust is well established in a field of corn.”<\/p>\n\n\n\n
