Shake well before using. Do not dilute. Spray weeds thoroughly when weather is dry and warm (application rate: 6-9 oz/yd2). If rain falls within three hours of application an additional application may be required. Repeat treatment every 2 to 3 weeks for control of new growth. Avoid spraying desirable plants. For optimum results spray weeds before they reach 5 inches in size. For control of dandelions and other large rooted weeds, first injure plant by splitting top of root; then apply 0.7 oz of Garden Safe Brand Weed & Grass Killer onto damaged root.
