Preen Weed & Grass Killer
Description
Preen Weed and Grass Killer is a ready-to-use spray for the control of a broad spectrum of emerged annual and perennial wood species. Its use will effectively control unwanted species of grass, sedge, broadleaf weeds, and certain woody species around trees, shrubs, and fences.
As it is non-selective, Preen Weed and Grass Killer will combat the growth of all vegetation, and is therefore not recommended for spot weed control in lawns.
With environmental protection always a chief concern for Preen, non-absorbed weed and grass killer will break down into natural materials, with no residual soil activity to harm wanted vegetation. For best results, be sure to use Preen Weed and Grass Killer when weed species are actively growing.
Application
How to Apply
Preen Weed and Grass Killer herbicide is formulated for “spot” treatment of inividual weeds and grasses. This product is ready-to-use (RTU) and is applied directly from the container fitted with a trigger sprayer. Adjust the sprayer tip to deliver coarse spray droplets to the individual weeds. Direct the spray to the target weeds – the ones you want to kill – to provide uniform and thorough coverage. Apply on a spray-to-wet basis.
One application will kill most of the weeds listed. Weeds usually begin to wilt within hours with complete kill in 1 to 2 weeks. Rain or watering 2 hours after application will not wash away effectiveness
When to Apply
Apply when the weeds are growing actively and air temperatures are above 60°F. Spray [Use] when air is calm to prevent drift to desirable plants.
