|Trade Name: Freehand||Common Name: dimethenamid-p + pendimethalin||Formulation: 1.75 GR (0.75 + 1%)|
Preemergence control of most annual broadleaf weeds, annual grasses and yellow nutsedge in container and field-grown woody nursery stock, landscape ornamentals and groundcovers.
|Amount of Active Ingredient||Amount by Formulation|
|Per Acre||1.75 to 3.5 lb||100 to 200 lb|
|Per 1,000 sq. ft.||2.3 to 4.6 lb|
Many annual weeds including annual grasses, annual sedges, spurge, oxalis, doveweed, willowherb and many others. Higher doses are required for bittercress, groundsel, sowthistle, and marsh parsley control. Suppression of eclipta, phyllanthus, and yellow nutsedge.
Injury to some species of herbaceous ornamentals has been reported including rudbeckia, stachys, begonia, muhlenbergia, and Pennisetum setaceum. Do use in propagation or liner production. Applications to newly transplanted rooted cuttings or seedlings of loropetalum, Lavendula, wax myrtle (seedlings) can stunt plant growth. Delay applications to these species until plants are well established.
In containers, 6 to 8 weeks of residual control of susceptible species has been observed. In soil (landscape of field nursery), up to 12 weeks of residual control can be expected. Weeds requiring higher doses will be controlled for shorter periods of time.
Pendimethalin: slight loss from the soil surface can result from photodegradation and volatility. Irrigation soon after application will limit these losses. Strongly adsorbed to soil organic matter and clay and, therefore, not leached. Dimethenamid-p: moderate volatility and leaching potential but adsorbed strongly to soil organic matter limiting leaching.
Dimethenamid-p inhibits lipid synthesis. Injury symptoms include crinkling of new growth, new leaves remaining “rolled” and not unfurling normally, and general stunting. Pendimethalin inhibits root growth causing swollen, club-shaped roots. HRAC Groups K1 and K3; WSSA Groups 3 and 15.
