This page includes the strategy for using the pull behind sprayer and the different yard areas.
Below from Label here. US EPA Fact Sheet here.
- Do not exceed specified dosages for any area. Be particularly careful within dripline of trees and other ornamental species.
- Do not apply this product to ‘Floratam’ or Bitterblue’ varieties of St. Augustinegrass in Florida.
- Do not apply this product to St. Augustine grass during spring green-up which is the transition period between dormancy and active growth.
- Do not spray roots of trees and ornamentals.
- Use on:
- Common Bermudagrass
- Hybrid Bermudagrass
- Bahiagrass
- Zoysiagrass
- Buffalograss
- St. Augustinegrass
- Centipedegrass
- For Warm Season Turfgrass, mix 0.75 – 1.5 fl. oz. of ferti-lome® Weed Free Zone per 1.0 gallon of water for treatment of approximately 1,000 sq. ft. of turfgrass. Apply any time the emerged broadleaf weeds are susceptible. Spray the target weeds thoroughly and wet the entire leaf surface of the undesirable plants.
- Rainfast in three hours.
- ACTIVE INGREDIENTS:
- 2,4-D, 2-ethylhexyl ester…………..10.49%
- Mecoprop-p, acid…………………….. 2.66%
- Dicamba, acid …………………………. 0.67%
- Carfentrazone-ethyl………………….. 0.54%
- INERT INGREDIENTS:………………..85.64%
- TOTAL: ………………………………….100.00%
- Broadcast (entire areas) applications or follow-up applications at 2-6 week intervals are recommended for more mature weeds, for dense infestations, and for adverse environmental conditions.
- Spot treatments during summer may be appropriate for sparse infestations, or as a follow-up treatment, or any time broadleaf weeds are susceptible.
- Irrigation: Do not apply this product immediately before rainfall or irrigation. Rain or watering within 4 hours after treatment may reduce effectiveness.
- Mowing: Delay mowing 1 to 2 days before and after the application of this product.
- For St. Augustine grass – apply 0.75 – 1.5 oz. per 1,000 SF. On 10/10/2021, found an error in mix calculations that applied well below the minimum of 0.75 oz. per 1000 SF. Notes from that post are pasted below.
- [NOTE on 10/10/2021 – This calculation is the higher labeled rate for WFZ per 1000 SF but incorrectly mixed it into a gallon and a gallon covers about 3000 SF in our little pull behind sprayer. So, the good news is that the very “weak” solution was enough to kill the target weeds; in particular FL Betony and Spider Wort. Computing the actual oz/KSF applied is af follows. 1.25 oz per gallon was sprayed over 1gal/0.375 gal/KSF = 2.67 KSF. Therefore, 1.25 oz / 2.67 KSF = 0.46 oz/KSF with 1 oz. non-ionized surfactant per gallon.
Non-ionized Surfactant – The label does not include the word surfactant and the only mention found on the web was the response by Do-My-Own to the question of whether or not to use some with WFZ. The response was it “could be used”. Other 2,4-D products use 0.25% non-ionized surfactant.
