Typical 2,4-D Amine 4 Rate Ranges
Actual rates vary by product formulation and target weeds, so always confirm against your specific label — these are common industry starting points.
| Use Site | Typical Rate | Context / Details |
|---|---|---|
| Lawn / Turf Spot Spray | 1 – 1.5 pt/acre | Light broadleaf weed pressure in established turf |
| General Pasture | 1.5 – 2 pt/acre | Standard broadleaf control in grazing land |
| Heavy Weed Pressure | 2 – 3 pt/acre | Dense or resistant broadleaf weed stands |
| Brush / Woody Plants | 3 – 4 pt/acre | Higher rate for tougher woody species |
| Fence Line / Non-Crop | 2 – 4 pt/acre | Total vegetation control where permitted by label |
2,4-D Amine 4 Mixing FAQ
Everything you need to know about mix ratios, spray volumes, and safe application.
Label rates for 2,4-D Amine 4 (4 lb acid equivalent per gallon) typically range from 1 to 4 pints per acre depending on the target weeds and site, such as turf, pasture, or non-crop areas. The mixing ratio in ounces per gallon then depends on how much carrier water (spray volume) you use per acre, so always check your specific product label first.
This depends on your target application rate per acre and your sprayer’s carrier volume (gallons per acre). For example, at 2 pints per acre in a 20-gallon-per-acre carrier volume, that works out to roughly 1.6 fluid ounces of product per gallon of spray solution.
Some 2,4-D products can be tank-mixed with other herbicides for broader spectrum control, but compatibility depends on the specific products involved. Always check the product label and, when unsure, run a small jar compatibility test before mixing a full tank.
2,4-D is best applied on calm days with wind speeds under about 10 mph to reduce drift risk, and when temperatures are moderate, generally below 85 to 90°F, since heat and volatility can increase the chance of vapor drift onto nearby sensitive plants.
Wait times vary by product label and use site, but many labels recommend waiting at least 24 to 48 hours before mowing to allow absorption, and grazing restrictions for livestock can range from a few days to several weeks. Always check the specific restrictions printed on your product’s label.
