Understanding the range of plants that Crossbow targets is essential for anyone looking to maintain healthy landscapes or improve crop yields. This herbicide is known for its selective action, addressing specific broadleaf weeds and woody plants without causing widespread damage to desirable grasses or crops. Its formulation and mode of action make it a valuable tool in the ongoing battle against invasive and competitive vegetation.

As you delve deeper into the topic, you’ll discover the types of weeds and brush that Crossbow effectively controls, as well as considerations for its safe and responsible use. Whether you’re a gardener, farmer, or land manager, gaining insight into what Crossbow herbicide kills will empower you to make informed decisions for your weed management needs.

Types of Weeds Controlled by Crossbow Herbicide

Crossbow herbicide is specifically formulated to target and control a broad spectrum of woody brush and broadleaf weeds. Its active ingredients, triclopyr and 2,4-D, work synergistically to effectively manage unwanted vegetation in pastures, rangelands, and non-crop areas. The herbicide is particularly effective against species that are difficult to eradicate with conventional herbicides.

Among the primary targets of Crossbow are:

  • Woody brush species such as kudzu, multiflora rose, and poison ivy
  • Broadleaf weeds including dandelion, clover, and ragweed
  • Certain invasive shrubs and vines that compromise pasture productivity

Due to its selective action, Crossbow allows grasses to thrive while suppressing undesirable vegetation, making it a preferred choice for pasture and rangeland management.

How Crossbow Herbicide Affects Different Plant Types

The combination of triclopyr and 2,4-D in Crossbow acts as a systemic herbicide, meaning it is absorbed through the foliage and transported throughout the plant’s vascular system. This systemic activity ensures the herbicide reaches the roots, effectively killing the entire plant over time.

The mode of action includes:

  • Mimicking natural plant hormones (auxins), causing uncontrolled and disorganized growth
  • Disrupting cellular processes, leading to plant death
  • Targeting broadleaf and woody plants without harming grasses

Grasses generally exhibit tolerance to the herbicide because they have different physiological responses to auxin mimics. This selective toxicity is beneficial in pasture settings where maintaining grass cover is essential.

Specific Weeds and Brush Controlled by Crossbow

The effectiveness of Crossbow spans a wide variety of problematic species commonly found in agricultural and non-crop land settings. The following table lists notable weeds and brush controlled by Crossbow herbicide:

Plant Species Type Common Name
Vitis spp. Woody Vine Wild grape
Rosa multiflora Shrub Multiflora rose
Parthenium hysterophorus Broadleaf Weed Ragweed
Ipomoea spp. Vine Morning glory
Celastrus orbiculatus Woody Vine Oriental bittersweet
Arctium minus Broadleaf Weed Burdock
Toxicodendron radicans Woody Vine Poison ivy
Rubus spp. Shrub Blackberry

This diverse spectrum of control makes Crossbow a versatile option for land managers aiming to reduce invasive and undesirable vegetation without harming native or desirable grasses.

Limitations and Plants Not Controlled by Crossbow

While Crossbow is effective against many broadleaf and woody species, it is not designed to control all types of weeds or plants. Limitations include:

  • Grasses and grass-like plants are generally unaffected, which is beneficial in pastures but limits use in turf or ornamental grass control
  • Some perennial weeds with deep root systems may require repeated applications or integrated management approaches
  • Crossbow does not control sedges, ferns, or certain monocots

Understanding these limitations is crucial for effective weed management planning. In cases where Crossbow alone is insufficient, combining it with other herbicides or mechanical control methods may be necessary.

Recommended Application Practices for Optimal Control

Achieving the best results with Crossbow involves applying the herbicide under conditions favorable for uptake and translocation. Recommended practices include:

  • Applying during active growth stages when plants are metabolically active
  • Avoiding application during drought stress or extreme temperatures
  • Ensuring thorough coverage of foliage for systemic absorption
  • Using appropriate rates as specified on the product label to balance efficacy and safety

Adhering to these practices enhances the herbicide’s ability to kill targeted species while preserving desired vegetation. Monitoring treated areas and reapplying if necessary can improve long-term control outcomes.
