Buckhorn Plantain
Plantago lanceolata
Buckhorn Plantain (Plantago lanceolata) is a perennial broadleaf weed characterized by narrow, lance-shaped leaves with prominent ribs radiating from base; cylindrical brown seed head on long naked stalk.. It anchors via a deep fleshy taproot root system and is selectively controlled using 2,4-D + Dicamba combination spray applied during autumn application during active nutrient translocation..
2,4-D + Dicamba combination spray
Narrow, lance-shaped leaves with prominent ribs radiating from base; cylindrical brown seed head on long naked stalk.
Always read and follow the manufacturer's EPA-approved pesticide product label. The label is the law under federal FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act) regulations. Application rates, personal protective equipment (PPE), target weed maturity stages, temperature restrictions, and grazing or re-entry intervals specified on the EPA container label supersede all online recommendations. Local state regulations may restrict certain active ingredients.

Botanical Identification Key for Buckhorn Plantain
Accurately identifying Plantago lanceolata is essential because spraying non-selective chemicals like glyphosate risks killing desirable lawn grass. Look for these botanical hallmarks:
- Foliar Morphology: Narrow, lance-shaped leaves with prominent ribs radiating from base; cylindrical brown seed head on long naked stalk..
- Root Architecture: Anchored by a deep fleshy taproot, making manual pulling ineffective unless the entire root crown is extracted.
- Growth Period: Active during perennial cycles, flourishing when lawn turf is stressed or cut too short.
Eradication Protocol & Selective Herbicide Selection
To eradicate Buckhorn Plantain while preserving your lawn turfgrass, apply 2,4-D + Dicamba combination spray during Autumn application during active nutrient translocation.. Ensure that the active ingredients match your host turfgrass tolerances:
- Temperature Safety Band: Apply when ambient air temperatures range between 65°F and 85°F. Never apply volatile ester herbicides in temperatures exceeding 85°F to prevent herbicide vapor drift and leaf burn.
- Adjuvant / Surfactant: For waxy or hairy weed foliage, mix with a methylated seed oil (MSO) or non-ionic surfactant according to EPA label instructions to enhance chemical cuticle penetration.
- Mowing Holdback: Do not mow the lawn 2 days prior to spraying or 2 days after application to maximize foliar surface area for chemical absorption.
Frequently Asked Questions About Buckhorn Plantain
01 How do I kill Buckhorn Plantain without harming my lawn?
Use a selective herbicide labeled for your specific turfgrass species containing 2,4-D + Dicamba combination spray. Spray when Buckhorn Plantain is actively growing during autumn application during active nutrient translocation.. Always check your host grass in our weed triage tool before application.
02 Why does pulling Buckhorn Plantain by hand often fail?
Buckhorn Plantain anchors via a deep fleshy taproot. Hand-pulling often breaks the crown or leaves underground root fragments, rhizomes, or nutlets behind, which triggers rapid regrowth. Systemic selective herbicides translocate down through the vascular tissue to destroy the entire root structure.
03 What class of weed is Buckhorn Plantain?
Buckhorn Plantain is classified botanically as a Broadleaf weed with a Perennial life cycle.
04 When is the best time of year to treat Buckhorn Plantain?
The optimal eradication window is Autumn application during active nutrient translocation.. Applying when temperatures are between 60°F and 85°F ensures maximum chemical absorption and prevents foliar heat stress to your desirable lawn.
