Product Label Safety Data Sheet

What does LESCO Stonewall 14-0-7 do?

It pairs fertilizer with 0.43% prodiamine, a pre-emergent herbicide that helps prevent crabgrass, annual bluegrass, and other label-listed weeds before they emerge. It does not control established weeds.

What is the active ingredient?

Stonewall contains 0.43% prodiamine, a Group 3 pre-emergent herbicide. Follow label directions for use and turf-specific annual limits.

What does the 14-0-7 fertilizer analysis mean?

The formula contains 14% nitrogen, 0% phosphate, and 7% potash. It feeds established turf while delivering pre-emergent weed prevention.

How much of the nitrogen is slow release?

30% of its total nitrogen is from PolyPlus OPTI45 controlled-release nitrogen. The guaranteed analysis identifies 4.20% slowly available urea nitrogen.

How much area will one 50 lb bag cover?

At a general planning rate of 4–5 lb per 1,000 sq ft, a bag covers about 10,000–12,500 sq ft. Consult the product label for your turf's application and annual maximum rates.

When should I apply Stonewall 14-0-7?

Apply before target weed seeds germinate. Early spring is common for crabgrass prevention, while late summer or fall can target annual bluegrass. Coordinate fertilizer timing with your grass's active growth period.

Will this product kill crabgrass that has already emerged?

No. Prodiamine prevents germinating weed seeds from establishing; it is not intended to kill existing mature weeds.

Do I need to water the product in?

Yes. To activate the pre-emergent treatment, the label calls for at least 0.5 inch of rain or irrigation before weed germination and within 14 days after application.

How long must I wait before overseeding?

The labeled waiting period after application varies from 4–10 months depending on rate and region. Do not apply to newly overseeded turf within 60 days after seeding or before the second mowing, whichever is longer. Check the actual product label table.

Can it be used on every lawn grass?

Only use on label-listed established turf. Maximum annual rates differ by grass: for example, tall fescue and bermudagrass have an 8.01 lb per 1,000 sq ft yearly maximum, whereas Kentucky bluegrass and perennial ryegrass have a 5.34 lb maximum. Lower limits apply to some other species.
