Below are a few words about peanut post emerge weed control in peanuts from Dr. Eric Prostko.<\/p>\n\n\n\n

Here are a couple of quick pics\/comments about POST weed control in peanuts based upon research plots that were rated earlier today (June 6).\u00a0 FYI, I did not get any activating moisture for the PRE herbicides for 8-9 days after planting (DAP) due to irrigation system problems.\u00a0 PRE treatments that included Valor still performed very well in this scenario.\u00a0 \u00a0<\/p>\n\n\n\n

1) No “cracking” herbicides were applied.  I prefer to get Cadre out around 30 DAP.  Not sand-bagging “cracking” treatments.  Gramoxone (paraquat) should be used when needed.  <\/p>\n\n\n\n

2) My original intention in this test was to just apply Cadre + 2,4-DB + Dual Magnum POST but the lack of a PRE activating moisture event forced me to add some Cobra, especially when PRE’s did not include Valor.<\/p>\n\n\n\n

3) If a grower has pigweed and is not sure if it is ALS-resistant or not (most likely will be<\/em>), it would be a good idea to add either Cobra or Ultra Blazer to the Cadre + DB + Dual Magnum tank-mixture.  Other than price (Cobra is more expensive by about ~$5-10\/A<\/em>), no difference between Cobra or Ultra Blazer when pigweeds are small (<3″).  But, Cobra would be preferred if pigweeds are bigger.<\/p>\n\n\n\n

4) Growers can also use Anthem Flex, Outlook, Warrant, or Zidua instead of Dual Magnum.  Anthem Flex will cause more leaf burn because it contains a small amount of Aim (carfentrazone). Here is what that looks like 12 DAT.<\/p>\n\n\n\n

1) Despite the lack of a timely rainfall\/irrigation event, Valor performed very well.<\/p>\n\n\n\n

2) No “cracking” herbicides were applied.  I prefer to get Cadre out around 30 DAP.  Not sand-bagging “cracking” treatments.  Gramoxone (paraquat) should be used when needed.  <\/p>\n\n\n\n

3) Really no need for an NIS with Dual Magnum or Outlook (EC formulations). But, need NIS when using Anthem Flex or Warrant.<\/p>\n\n\n\n

4) Here is what Cadre + Anthem Flex + 2,4-DB + Induce looks like at 6 DAT.<\/p>\n\n\n\n

1) Gentle Ben and I (+ Nick Shay, PhD graduate student) put out a quick and dirty test for the control of what we think (?) is spreading dayflower (Commelina diffusa<\/em>).  We will confirm the exact species (with RC from VSU<\/em>) when we can collect some plants with flowers.<\/p>\n\n\n\n

2) These “cracking” treatments looked great at 3 DAT.<\/p>\n\n\n\n

3) Did you know that in Georgia there are 6 species of Commelina<\/em> and 2 species of Murdannia<\/em> that look very similar?<\/p>\n\n\n\n

Commelina benghalensi<\/em>s – Benghal dayflower (formerly tropical spiderwort)<\/p>\n\n\n\n

Commelina caroliniana<\/em> – Carolina dayflower<\/p>\n\n\n\n

Commelina communis<\/em> – Asiatic dayflower<\/p>\n\n\n\n

Commelina diffusa<\/em> – spreading dayflower<\/p>\n\n\n\n

Commelina erecta<\/em> – erect dayflower<\/p>\n\n\n\n

Commelina virginica<\/em> – Virginia dayflower<\/p>\n\n\n\n

Murdannia keisak<\/em> – marsh dayflower<\/p>\n\n\n\n
