|Trade Name: Snapshot TG||Common Name: isoxaben + trifluralin||Formulation: 2.5 TG (0.5 + 2.0%)|
Preemergence control of most annual broadleaf weeds and annual grasses in container or field grown nursery crops, landscape plantings, Christmas tree plantations, nonbearing fruit trees, and groundcovers.
|Amount of Active Ingredient||Amount by Formulation|
|Per Acre||2.5 to 5 lb
(0.5 to 1 lb isoxaben + 2 to 4 lb trifluralin)
|100 to 200 lb|
|Per 1,000 sq. ft.||2.3 to 4.6 lb|
Major Weeds Controlled
Broad spectrum control of annual broadleaf and grass weeds including chickweed, henbit, groundsel, annual bluegrass, crabgrass, carpetweed, and many others.
Major Weeds Not Controlled
Perennials and established weeds. Weak on bittercress, spurge, and phyllanthus, doveweed, morningglory and rice flat sedge. Does not control nutsedge.
For Best Results
Apply in late summer to early fall or in early spring before the emergence of target weeds or immediately after cultivation. One-half inch or more of water is required within three days for activation. In containers, hand weed before treatment and irrigate immediately after application.
Cautions and Precautions
Do not apply to new transplants until soil has settled and there are no cracks. Do not apply to nursery seedbeds or transplant beds or to unrooted liners or cuttings. Do not apply to bedding plants or to areas where bedding plants will be planted within one year. Do not apply to pots less than 4 inches wide. Repeat applications of 150 pounds per acre or more should not be made less than 60 days after previous application. Apply no more than 600 pounds per acre in a 12-month period. Use is prohibited on several species, check label for details.
Duration of weed control varies with application rate, management practices, and prevailing weather conditions. In cool climates or seasons, longer residual is expected than in warm climates or seasons. In containers, residual weed control rarely lasts more than 60 days in the southeastern US. Shorter residual is to be expected in mid-summer; longer residual in cooler weather.
Volatility and Leaching Potential
Isoxaben is nonvolatile. Trifluralin is somewhat volatile; therefore, the herbicide should be incorporated by irrigation or rain soon after application. Isoxaben leaches very little; trifluralin is strongly adsorbed to soil and thus little leaching occurs.
Symptoms and Mode of Action
Isoxaben is a cell division inhibitor appears to disrupt root and hypocotyl development. Group 29.
Trifluralin affects root growth by inhibiting cell division. Group 3.
