Residual herbicides applied once to soil along established agave growing in a Cerini clay loam.  Treatments included Chateau SW (flumioxazin) at 12 oz/a (0.38 lbai/a), Trellis (isoxaben) at 1.33 lb /a (1.0 lb ai/a), Alion (indaziflam) at 3.5 fl oz/a (0.046 lb ai/a), Prowl H2O (pendimethalin) at 4 qt/a (3.8 lb ai/a), GoalTender (oxyfluorfen) at 3 pt/a (1.5 lb ai/a), Matrix (rimfulsuron) at 4 oz/a (0.063 lb ai/a), Mission (flazasulfuron) at 2.14 oz/a (0.033 lb ai/a), Direx (diuron) at 1.6 qt/a (1.6 lb ai/a), Barricade 65 WG (prodiamine) at 1.0 lb/a (0.65 lb ai/a), and Dimension (dithiopyr) at 2 pt/a (0.5 lb ai/a).  Weed control data not collected due to sparse weed population. None of the treatments caused any crop injury.

Postemergence herbicides post-directed once along established agave growing in a Cerini clay loam.  No injury seen from any post-directed treatment through 62 days after treatment (DAT).  Glyphosate: Roundup PowerMAX3 at 20.4 fl oz/a (0.75 lb ae/a) + AMS and Rodeo at 32 fl oz/a (1.0 lb ae/a) + NIS included in treatment list.  Weed control 29 DAT was identical from each product, ranging from 63 to 83%, depending on species. Carfentrazone:  Shark EW at 2 fl oz/a (0.03 lb ai/a) + COC provide poor weed control 29 DAT.  Pyraflufen:  Venue at 3 fl oz/a (0.004 lb ai/a) + COC provided no control of weeds present in this trial.  Florpyrauxifen:  Hulk at 1 pt/a (0.026 lb ai/a) + MSO provided no control of weeds present in this trial.  2,4-D Choline:  Embed Extra at 2 pt/a (0.95 lb ae/a) provided poor control of weeds present in this trial.  Quinclorac:  Quinstar at 12 fl oz/a (0.375 lb ai/a) + COC + AMS provided no control of weeds present in this trial.  Tiafenacil:  Tiafenacil 70 WG at 1 oz/a (0.044 lb ai/a) + MSO controlled weeds ~50% 29 DAT.  Clethodim:  Select Max at 12 fl oz/a (0.09 lb ai/a) + NIS did not control the broadleaf weeds present, as expected.  Saflufenacil:  Treevix at 1 oz/a (0.044 lb ai/a) + MSO + AMS provided ~60% control of weeds present at 29 DAT.  This treatment was also applied broadcast over the crop and controlled weed ~50% at 29 DAT.  This treatment also caused crop injury, which was still nearly 20% at 62 DAT.
