22-0-0 Pre-emergent Fertilizer w/ .15% Dimension - 50 lb Bag

Dimension* 0.15% + Fertilizer provides "preemergence" control of crabgrass in established turfgrasses (including the large, smooth, and southern species) when applied prior to germination and emergence of crabgrass. This product also provides "early postemergence" control of crabgrass if applied prior to the 3-leaf stage of growth or first tiller as described below. This stage of growth generally corresponds to the time when crabgrass seedlings first become visible in the established turfgrass. The practical benefit of early postemergence crabgrass control is a 2 - 4 week longer period of time (window of application) during which crabgrass control can be achieved. This is included in our Lawn Care Program as Step 2.

22-0-0 Pre-emergent with .15% Dimension

This product may be used on seeded, sodded, or sprigged lawns and ornamental turfs that are well-established. Initial application of this product should be made only after turf-grasses have developed a vigorous root system, a uniform stand, and have received at least two mowings following seeding, sodding, or sprigging. Use of this product on turf-grasses that are not well-established, or weakened by stress from weather, pests, disease, chemical, or mechanical influences, may increase the chances of turf injury

Early post-emergence weed control with this product is limited to crabgrass. Post-emergence application effectively controls crabgrass, but only if application is made prior to the 3-leaf stage of growth or first tiller.
