16 Weed Control in Peanuts2007 Peanut Production Guide
WEED CONTROL IN PEANUTS J.C. Faircloth, Extension Peanut/Cotton Specialist
Perennial Broadleaf Weeds: Perennial broadleaf weeds such as horsenettle, trumpetcreeper,maypoppassionflower,andbigrootmorningglorycannotbeeffectively controlled in peanuts. Treatment with Blazer plus 2,4-DB will provide some foliage burn and growth suppression of these weeds. Perennial weeds rapidly recover from these treatments. Perennial weeds can be controlled in corn grown in rotation with peanuts. In corn, make a layby application of 1 pt per acre of 2,4-D amine plus surfactant. After corn harvest, spot spray remaining infestations with either glyphosate or a mixture of 2,4-D amine plus 0.5 pt per acre of Banvel plus surfactant. See the product labels for suggested application rates.
Bermudagrass: Two applications of Poast, Poast Plus, or Select will usually provide adequate to good control of bermudagrass in vigorously growing peanuts. See Table 10 for application rates and weed size for treatment. Strive for good control in rotational crops. In soybeans and cotton, Assure II, Fusilade DX, Fusion, SelectMax, Poast, and Poast Plus are registered for postemergence control of bermudagrass.
Broadleaf signalgrass: Sequential herbicide applications are usually necessary to provide adequate control of this annual grass. Apply Prowl, Dual Magnum, or Sonalan as a preplant incorporated treatment and follow with an application of either Lasso or Dual Magnum about the time peanuts emerge. Shallow cultivation and/or a postemergence application of Poast, Poast Plus, or SelectMax may be required in addition to use of soil-applied herbicides. Gramoxone Max or Boa will provide good to excellent control if applied to seedlings with 3 leaves or less.
Texas Panicum: This annual grass is expanding as a problem weed in most peanut-producing counties in Virginia. Lasso, Dual Magnum, Frontier, Outlook and Pursuit will not control Texas panicum. Soil incorporated treatments of Prowl or Sonalan will generally provide good to excellent control. Prowl or Sonalan should be incorporated to a depth of 3 inches (this is deeper than specifiedonProwllabel).Poast,PoastPlus,orSelectMaxprovideexcellentpostemergence control of Texas panicum. Gramoxone Max or Boa will provide good to excellent control if applied to seedlings with 3 leaves or less.
Nutsedge: Both yellow and purple nutsedge occur in Virginia’s peanut production area. For either species, sequential herbicide application and/or cultivation may be necessary to obtain satisfactory control. Yellow nutsedge suppression or control can be achieved with soil applications of Pursuit, Strongarm, Frontier, Outlook, or Dual Magnum. Lasso, Frontier, Outlook, or Dual Magnum may be applied as a preemergence or an at-cracking treatment to improve control or suppression of yellow nutsedge. Purple nutsedge suppression can be obtained with a soil application of Pursuit or Strongarm.
Weed Control in Peanuts 172006 Peanut Production Guide
If yellow nutsedge escapes soil applied herbicides, Basagran may be applied postemergence to improve control. Apply Basagran when yellow nutsedge is 6 to 8 inches tall. Both yellow and purple nutsedge can be controlled or suppressed with a postemergence application of either Cadre or Pursuit to nutsedge 1 to 3 inches in height.
Prickly sida, ragweed, tropic croton, eclipta, spurred anoda, and velvetleaf: A soil incorporated treatment of Pursuit usually provides good control of prickly sida and spurred anoda, and fair to good control of velvetleaf. Soil applied treatments of Strongarm generally will provide good control of common ragweed and eclipta. No soil applied treatments are available which will satisfactorily control tropic croton.
Basagran, Cadre, or Tough may be used for effective postemergence control of prickly sida. Blazer provides good to excellent control of ragweed and tropic croton. Postemergence application of Blazer at 2 pt per acre will suppress and may control eclipta less than 2 inches tall. (Control not claimed on Blazer label.) Cadre provides good postemergence control of spurred anoda. Refer to product labelsforspecificdetailsofapplicationinformationbasedonweedspeciesandsize.
Lambsquarters: Soil-incorporated Strongarm, Sonalan, Pursuit, or Prowl will provide good lambsquarters control. For postemergence control with either Basagran or Blazer, treatments must be applied when lambsquarters seedlings are 2 inches in height or less. Tank mixture of 2,4-DB with Blazer or Basagran improves consistency of lambsquarters control.
Herbicide Injury
Early-season peanut injury may occasionally result from use of soil-applied herbicides. Symptoms of this injury include excessive swelling of the hypocotyl, curling or corkscrew-like growth of the hypocotyl, moderate to severe inhibition (pruning) of root growth, failure of seedlings to emerge or slow seedling emergence, and stunted growth of emerged seedlings. These symptoms may be mimicked or aggravated by weather conditions and low seed vigor or quality. Peanuts usually outgrow this injury with no reduction in yield.
Injury has most commonly been noted with soil-incorporated applications to very sandy soils where the herbicide has not been uniformly mixed with the soil and rainfall has been received or irrigation applied within several days of planting. Preemergence and cracking stage applications are less likely to cause injury than soil-incorporated treatments. Sequential applications of chloroacetamide herbicides (Frontier, Outlook, Dual Magnum, or Lasso) may increase the potential for injury.

Table 16. Adjuvant Recommendations for Postemergence Herbicides
Herbicide Application Method Adjuvant recommendations
Basagran Ground 2.0 pt/A crop-oil concentrate when treating lambsquarters, common ragweed, hemp sesbania, or yellow nutsedge. Vegetable oils may be used. Use 1.0 gal/A of 30% nitrogen instead of crop-oil concentrate if velvetleaf is the primary target weed.
Air 1.0 pt/A crop-oil concentrate when treating lambsquarters, common ragweed, hemp sesbania, or yellow nutsedge. Vegetable oils may be used. Do not use 30% nitrogen with aerial applications.
Ultra Blazer Ground or Air Use 0.125 percent nonionic surfactant for most weeds. For lambsquarters, hemp sesbania, or cowpea, use 0.25 percent nonionic surfactant or 0.5 to 1.0 gal/A of 30% nitrogen.
Cadre Ground only Use 0.25 percent nonionic surfactant or 2 pt/A crop-oil concentrate.
Cobra Ground only Add nonionic surfactant at 1 qt/100 gallons or petroleum or vegetable based crop oil concentrate at 1 to 1.5 pt per acre (Seelabelforspecifics).
Select Ground Always use 2.0 pt/A crop-oil concentrate.
SelectMax Ground 0.25% nonionic surfactant, 1% crop-oil concentrate or 1% methylated seed oil.
BoaGramoxone
Ground Use 0.125 percent nonionic surfactant in cracking stage sprays.
PoastPoast Plus
Ground or Air 2.0 pt/A crop-oil concentrate. Vegetable oils may be used.
Pursuit Ground Use a petroleum or vegetable seed based oil concentrate at a rate of 1.5 to 2.0 pt/A or a nonionic surfactant containing at least 80% active ingredient at 1 qt/100 gallons of spray mixture.
Storm Ground or Air 2.0 pt/A crop-oil concentrate. Vegetable oils may be used.
Note: Information in this table was taken from product labels. See the labels. See the labelsforadjuvantrecommendationswithspecifictankmixes.
Adjuvant rates given in percentages are on a volume/volume basis:
0.125% - 1 pt per 100 gal of spray solution; 0.50% - 2 qt per 100 gal of spray solution;
0.25% - 1 qt per 100 gal of spray solution; 1.00% - 4 qt per 100 gal of spray solution.
