Surflan GT herbicide is a soluble concentrate, soil residual herbicide with foliar systemic activity. Surflan GT herbicide provides both non-selective and pre-emergent broad-spectrum control of many annual and perennial weeds. Pre-emergent, Surflan GT herbicide controls susceptible annual weeds by disrupting plant growth processes during germination.
Surflan GT herbicide also contains the active ingredient glyphosate, which inhibits an enzyme found only in plants and microorganisms that is essential to formation of specific amino acids. Susceptible weeds emerged at the time of application will be controlled by this product.
Time to Symptoms, Foliar Systemic Activity: The glyphosate component of Surflan GT herbicide moves through the plant from the point of foliage contact into the root system. Visible effects on most annual weeds occur within 2 to 4 days, but on many perennial weeds this may not occur for 7 days or more.
Extremely cool or cloudy weather following treatment may slow the activity of Surflan GT herbicide and delay development of visual symptoms. Visible effects are a gradual wilting and yellowing of the treated weed which advances to complete browning of above-ground growth and deterioration of underground weed parts.
Surflan GT herbicide is orange in color and may cause temporary discoloration of sprayed surfaces. If this discoloration is undesirable, it may be altered by using a commercially available green colorant such as Blazon; or removed by spraying surface with water, or washing with an industrial cleaner immediately after application.
Surflan GT herbicide may be applied in liquid sprays of water, and may be tank mixed with other herbicides to control existing vegetation or improve the spectrum of weeds controlled. Susceptible annual weeds germinating from seed after application will be controlled. Un-emerged weeds arising from unattached underground rhizomes or root stocks of perennials will be partially controlled or suppressed.
Cultural Considerations: Reduced burndown control may result when applications are made to annual or perennial weeds that have been mowed, grazed, or cut, and have not been allowed to re-grow to the specified stage for treatment.
Rainfastness: Heavy rainfall within 4 hours after application may wash this product off of the foliage and reduce the burndown effectiveness of Surflan GT herbicide. This however, will not reduce the residual effectiveness of Surflan GT herbicide that reaches the soil surface.
Spray Coverage: For best results, ensure that spray coverage is uniform and complete.
