Abstract/Contents: | "Broadleaf weeds make for an unsightly appearance in highly maintained turf areas as they are prolific seed producers and are widely distributed. The purpose of this research was to investigate the efficacy of various sulfonylurea herbicides for broadleaf weed control. In the spring of 2003 two studies were conducted at Clemson University, investigating broadleaf weed control with sulfonylurea herbicides. Plot size for each treatment measured 2.0 m by 3.0 m, replicated three times. Treatments were applied using a CO2 backpack sprayer calibrated at 20 GPA, at 30 p.s.i., with 8003 flat fan spray tips. Treatments for study 1 included: TranXit (25DG) at 0.03 lb ai/A; Manor (60DF) at 0.04 lb ai/A; Revolver (0.19SC) at 0.03 lb ai/A; Monument (75WG) at 0.03 lb ai/A; Katana (25DG) at 0.05 lb ai/A; Battalion (75DG) at 0.02 lb ai/A; Speed Zone (2.2L) at 1.1 lb ai/A; and Trimec Classic (3.32L) at 1.66 lb ai/A. Treatments for study 2 included: Katana (25DG) at 0.02 lb ai/A; Katana at 0.04 lb ai/A; Katana at 0.05 lb ai/A; Katana + MSMA (6SC) at 0.05 lb ai/A + 2.0 lb ai/A; Katana + 2,4-D (4L) at 0.05 lb ai/A + 1.0 lb ai/A; Speed Zone (2.2L) at 1.1 lb ai/A; and Trimec Classic (3.32L) at 1.66 lb ai/A. Initial applications for both studies were made on March 27, 2003. All treatments containing a sulfonylurea herbicide received Induce (nonionic surfactant) at 0.25% V/V. Visual broadleaf weed control ratings were taken 23 and 47 DAT. Ratings for broadleaf weed control were based on a scale of 0-100% with 0% representing no control and 100% representing complete control. Broadleaf weeds rated in study 1 include: Carolina Geranium (Geranium carolinianum), Dandelion (Taraxacum officinale), Field Madder (Sherardia arvensis), Curly Dock (Rumex crispus), Ground Ivy (Glechoma hederacea), Dichondra (Dichondra carolinensis), White Clover (Trifolium repens), Little Barley (Hordeum pusillum), Tall Fescue (Festuca arundinacia). Broadleaf weeds rated in study 2 include: Large Hop Clover (Trifolium campestre), Field Madder (Sherardia arvensis), Yellow Woodsorrel (Oxalis stricta), Dandelion (Taraxacum officinale) Common Chickweed (Stellaria media), and Rattail Fescue (Festuca myuros). By 47 DAT of study 1, >80% control of broadleaf weed species was achieved by: Dandelion and White Clover - all treatments; Carolina Geranium - TranXit, Manor, Revolver, Speed Zone, and Trimec Classic; Curly Dock - Speed Zone; Field Madder - TranXit and Katana; Ground Ivy - TranXit, Manor, Revolver, Monument, Katana, Speed Zone, and Trimec Classic; Dichondra - TranXit, Manor, Revolver, Monument, Katana, Speed Zone; Tall Fescue - TranXit, Revolver and Katana; and, Little Barley - TranXit, Revolver, Monument Katana, and Battalion. In study 2, >80% broadleaf weed control was achieved as by: Large Hop Clover, Field Madder, Common Chickweed - all treatments; Yellow Woodsorrel - Katana at 0.05 lb ai/A and Katana plus 2,4-D; Common Dandelion - Speed Zone; and, Rattail Fescue - all treatments containing Katana. Future research at Clemson University will be to continue to screening new and experimental sulfonylurea herbicides for broadleaf weed control." |
