Abstract/Contents:"Prodiamine is the common name for N3,N3, -Di-n-propyl-2,4-dinitro-6-(trifluoromethyl)-m-pheny lenediamine a dinitroaniline class herbicide. Promidiamine has low water solubility and atmospheric volatility with excellent soil persistence and herbicidal activity. The commercial product in turf, trade name Barricade, is formulated as a 65% water soluble granuale packaged in water dissolvable bags. Prodiamine (Barricade) is a broad spectrum product that gives full season control of annual grasses and many small seeded broadleaf weeds when applied and activated by rainfall or irrigation prior to the germination and emergence of the weed. Prodiamine (Barricade) prevents germination and inhibits root growth in susceptible species. Normal recommended rates for application are: 0.73 kg/ha (1.0 lb product) in Northern US, 0.91 kg/ha (1.25 lb product) in the Transition zone, and 1.10 kg/ha (1.5 lb product) in the Southern US. Annual grass weeds controlled include goosegrass (Elusine indica L.) ELEIN, annual bluegrass (Poa annua L.) POANN, smooth crabgrass (Digitaria ischaemum Schreb. ex. Schweig.) DIGIS, large crabgrass (Digitaria sanguinales L.) DIGSA and yellow foxtail (Setaria glauca L.) SETLU. Difficult to control weeds such as goosegrass respond best to sequential applications of prodiamine (Barricade). Small seeded annual broadleaf weeds controlled include prostrate spurge (Euphorbia humistrata Engelm. ex. Gray) EPHHT, henbit (Lamium amplexicaule L.) LAMAM, common chickweed (Stellaria media L.) STEME. One of the strengths of prodiamine (Barricade) is consistent long term control over a wide geography, relative to many currently used commercial standards. Prodiamine (Barricade) is safe to turfgrass species when used as directed. The maximum recommended annual rate for turfgrass ranges from 0.56 kg/ha (0.8 lb product) to 1.68 kg/ha (2.30 lb product) dependent upon the sensitivity of the turfgrass type, length of time turf is established and period of control desired. Unless otherwise directed in the use of directions, prodiamine (Barricade) should only be applied to turf that is filled in and established. Broadcast reseeding or overseeding can be done effectively if preplanning provides approximately 4-6 months waiting period for each 0.56 kg/ha (0.75 lb product) applied. This waiting interval can be shortened to 3-4 months if the turf surface is opened and seed is placed directly into the soil."
