Introduction
Trade Name: Fusilade II, Ornamec, others | Common Name: fluazifop-P-butyl | Formulations: 0.125 EC, 2 EC |
Uses
Selective postemergence control of annual and perennial grasses. May be applied over the top of many ornamentals including many woody and herbaceous ornamentals in container and field nurseries, landscapes and greenhouses.
Amount of Active Ingredient | Amount by Formulation | ||
0.125 EC | 2 EC | ||
Per Acre | 0.25 to 0.375 lb ai | 2 to 3 gal | 16 to 24 fl oz** |
Per 1,000 sq. ft. | 6 to 9 fl oz | 0.4 to 0.6 fl oz** | |
Spot Treatment (amount per gallon) | 10 fl oz | 0.75 fl oz |
**At reduced rates of 3 to 6 oz/A, Fusilade may also be used for bermudagrass suppression in tall fescue turf; see the product label for specific guidelines on doses, frequency and timing for such uses.
Major Weeds Controlled
Annual and most perennial grasses.
Major Weeds Not Controlled
Annual bluegrass, broadleaf weeds, sedges, rushes, lilies, and other nongrasses are not controlled. Red fescue, and sweet vernal grass have shown considerable tolerance. At low doses, tall fescue is not controlled.
For Best Results
Add a nonionic surfactant, 0.25% by volume. Some ready-to-use formulations are available; do not add additional surfactant to such formulations. Spray annual grasses at 2 to 8 inches tall. For perennial grass, spray during the spring growth flush but before heading. Cultivation two to three weeks after treatment may assist weed control. Thorough coverage is essential for optimum results; spray to cover but not to runoff. Optimum control is attained when weeds are not stressed.
Cautions and Precautions
Use only nonionic surfactants. Do not apply if rain is expected within 1 hour. Do not tank mix with other pesticides or fertilizers except as instructed on the label. A number of broadleaf ornamentals and conifers may be injured by over the top applications of fluazifop-p. Check the label restrictions on bluegreen junipers, azalea cultivars, and other species. Directed sprays are required to prevent unacceptable injury on these species. Do not apply to plants that may be harvested for food within one year.
Residual Activity
Up to two weeks of soil residual activity has been reported.
Volatility and Leaching Potential
Low volatility and negligible leaching occur when used as directed.
Symptoms and Mode of Action
Growth inhibition occurs within 48 hours. Meristems turn black shortly thereafter. Yellow to red foliage develops in about 7 to 10 days, and plants die within 14 days. Inhibits cell division by blocking acetyl Co A carboxylase, a lipid biosynthesis enzyme. MOA groups: WSSA Group 1; HRAC Group A.
