Pulverize Weed & Grass Killer kills unwanted weeds and grass fast with a versatile and non-staining formula safe for cultivated areas such as gardens and flowerbeds. Pulverize Weed & Grass Killer is a non-selective herbicide that controls many common annual weeds and suppresses some bi-annual and perennial weeds. Application Directions: Spray weeds thoroughly when weather is dry and warm (application rate 6-9oz/sqyd). If rain falls within three hours of application an additional application may be required. Repeat treatment every 2-3 weeds for control of new growth. Avoid spraying desirable plants. For best results, spray weeds before they reach 5 inches in size. For control of dandelions and other large rooted weeds, first injure the plant by splitting the top of the roof, then squirt 20 times with the sprayer set on stream setting.
