The intense and often<br \/>\noverwhelming rainfall in recent weeks has greatly limited our ability to be timely with weed<br \/>\nmanagement programs throughout Georgia. Below are a few discussion points to address<br \/>\ncommon questions\/concerns.<\/p>\n<p>1. Preemergence (PRE) herbicides in 2018 have been priceless providing excellent earlyseason<br \/>\ncontrol. Even after Palmer amaranth eventually emergences through the PRE<br \/>\nherbicides, its growth has been slowed providing a more timely first POST application.<br \/>\nUGA Cotton Team Newsletter<br \/>\nJune, 2018<br \/>\nFor growers who removed the PRE from their system\u2026\u2026\u2026\u2026..horrible decision. As we<br \/>\nmove into June, the PRE herbicide is just as important as ever because weeds emerge and<br \/>\ngrow more quickly in June and July than in April or May. As always, apply two active<br \/>\ningredients that are effective on Palmer amaranth and get the rates right for your soil type<br \/>\nand production practice thereby avoiding cotton injury.<\/p>\n<p>2. Postemergence (POST) herbicides are currently preforming exceptionally well in<br \/>\ncontrolling emerged weeds; including Roundup and our labeled dicamba and 2,4-D<br \/>\nproducts. It is worth mentioning that the performance of Liberty was hampered in late<br \/>\nMay because of consistently cloudy weather but since the sun has returned to South<br \/>\nGeorgia the herbicide is back to performing as expected and occasionally a little better<br \/>\nthan expected.<\/p>\n<p>3. Pigweed is big in many fields so keep in mind a systems approach including sequential<br \/>\nPOST applications and a layby containing products like diuron offer the best opportunity<br \/>\nfor success. CRITICAL to success is the time interval between your two POST applications;<br \/>\nintervals vary within a given technology. Go to gaweed.com to view cotton weed<br \/>\nmanagement programs and intervals between POST applications (or call your extension<br \/>\nagent)\u2026\u2026\u2026.if you are off a few days between sequential POST applications it could have<br \/>\ndramatic consequences.<\/p>\n<p>4. As mentioned above, herbicides are currently performing exceptionally well. Of course,<br \/>\nthat is good for weed control but it is not so great for cotton injury. UGA research has<br \/>\nconsistently shown most cotton postemergence herbicide mixtures can cause twice as<br \/>\nmuch injury when applied in saturated soil conditions as compared to ideal soil<br \/>\nconditions. Don\u2019t forget that research suggests that it is best to avoid herbicide damage<br \/>\nto cotton past the 8-leaf stage if any way possible\u2026\u2026yes, use the layby rig!!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cotton weed control (Culpepper) Weather has certainly challenged the management program.
