Turf may or may not be present or desired. Cultural practices for pest management. Use hand weeding or weed wackers to minimize pesticide use. If the surface is blacktop, cracks should be sealed regularly. If a fence is not needed yet weeds are a problem, the fencing could be removed.
Chemical controls for pest management.
Chemical weed control may provide much longer lasting weed control than hand weeding or weed whacking, particularly for perennial weeds. It is also useful for applying directly to, or mixing in with, asphalt to prevent weeds. Prometon has much longer residual activity than glyphosate and can control weeds for up to one year after application. Chemical control is most appropriate for blacktop parking lots due to the need to protect the large investment of these areas as weeds can cause crumbling of the blacktop as they emerge through small cracks or pores in the surface. Spot treatments are appropriate and should be performed when school is out of session.
