Don\u2019t think a \u201c1994-bargain-basement-teb-bravo\u201d is what this grower needs now. He or she needs Elatus or Excalia or Convoy or Umbra. Maybe Vantana.

Now? &nbsp;In Tifton? 79F and not yet 6 AM. White mold weather.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Roll call: Southern corn rust- wide-spread and growing across SE and SW districts. Corn not yet tasseling\u2026.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tar spot of corn- At least in Pulaski and Wilcox Counties<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fusarium ear rot of corn- very much widespread; can\u2019t do anything about it<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Peanut rust- confirmed in Seminole Co; where rust occurs, tighten spray intervals. &nbsp;Recognize that Miravis is an excellent leaf spot material but not for rust management.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Peanut leaf spot- simmering now wherever peanuts are grown in Georgia. Stay timely and aggressive. If leaf spot gains a toe-hold, consider calling a fungicide audible at the line of scrimmage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">White mold on peanuts- the current situation in many fields is white mold paradise. &nbsp;Where the disease is suppressed, you have flexibility in your fungicide program; where white mold has ignited- use all tools (fungicide selection, rate, timing, irrigation, spray volume, etc) to quench it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Areolate mildew- building in cotton across SE and SW districts- significant defoliation will result in significant yield loss. A single well-timed application of Miravis Top or Priaxor should do a good job. Sadly, resistance to azoxystrobin is real.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Target spot- much like areaolate mildew above, but Headline is also effective for this disease.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Soybeans\u2026. So far quiet on soybeans. But remember- a maintenance fungicide application at R3 early pod set, especially in combination with Dimilin, is a good thing.&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Row Crop Disease &#8211; Bob Kemerait My air conditioner is kicking on at 5 AM, weather across much of Georgia (warm muggy nights, hot humid days, sporadic rainfall and irrigation) is perfect for white mold gone wild in our peanut fields.
