Using Herbicides for Wildlife Management

Overview

When used according to label and with an IPM mindset, herbicides selectively control problem plants (e.g., exotic sod grasses, encroaching trees) while protecting forbs and legumes critical to wildlife foods and insects.

Where This Practice Applies

  • Cropland borders
  • Ditch banks
  • Open woodlands
  • Fire lines
  • Plot edges
  • Shooting lanes
  • Access trails

Species That Benefit

  • Quail
  • Songbirds
  • Rabbits
  • Deer (through increased browse diversity)

Benefits to Wildlife

  • Maintains seed/insect‑producing forbs
  • Opens ground layer
  • Extends food plot longevity

When to Use This Practice

  • Prior to establishing borders/native grasses (multiple treatments or season‑specific timing often required).
  • Mid‑rotation woody control in open forests, followed by spring burns to reduce litter and stimulate groundcover.

How It Works

Application types include basal bark, hack‑and‑squirt, thinline, spot soil treatments, and foliar sprays. Always use aquatic‑labeled products along ditches; understand soil activity, volatility, downhill movement, and translocation risks.

Step‑by‑Step Instructions

  1. Identify target species and choose selective products/timing (e.g., control fescue when it stays green later into fall).
  2. Apply minimally (spot or strip, not broadcast) to preserve beneficial plants.
  3. Follow labels and surfactant rules; consult label databases for safety and application specifics.

Common Mistakes to Avoid

  • Broadcast treatments that eliminate beneficial herbaceous plants
  • Using non‑aquatic labels near water
