In global agriculture and lawn care, weed management ensures high crop yields and beautiful landscapes. 2,4-D, Dicamba and Quinclorac are three highly effective herbicides, each known for its unique mechanism of action and spectrum of targeted weeds. Combining these three together not only extends the scope of weed control, but also enhances weed control efficiency through synergistic effects. In this paper, we will detail the properties of each herbicide and explore their revolutionary impact in hybrid applications.

1. 2,4-D: Control of broad-spectrum broadleaf weeds

Mechanism of action
2,4-D is a synthetic plant growth regulator (auxin mimic) that mimics the function of plant growth hormones. It works by accelerating cell division and growth in weeds, leading to growth disruption and ultimately causing the weed to wither and die.

Type: Belongs to the acyloxyacetic acid class of herbicides (Phenoxy Herbicides).
Mode of Absorption: Absorbed through leaves, stems or roots, with systemic action, the agent is transported to the growing point.

Target weeds
2,4-D is effective against a wide range of broadleaf weeds, esp:

Ragweed
Creeping Charlie
Wild Mustard

Areas of application
Widely used in

Lawns and golf courses
Wheat, corn and soybean fields
Non-cropland and road management

Advantages
Low cost and long lasting results
Crop safe (for grass crops)
Easy to mix with other herbicides

2. Dicamba: targets broadleaf weeds

Mechanism of action
Dicamba is a Benzoic Acid (Benzoic Acid) synthetic hormone herbicide, similar to 2,4-D, which interferes with the process of cell division and growth, causing weeds to grow abnormally until they die.

Mobility: Extremely systemic and can be rapidly transported within the plant to the growing point.
Residual: Remains active in the soil and prevents weed seeds from germinating.

Targeted weeds
Dicamba specializes in hardy species of broadleaf weeds:

Chicory
Dandelion
Marigold

Areas of application
Agricultural fields: for corn, soybeans, wheat and other tolerant crops.
Lawns and public green spaces: to remove a wide range of broadleaf weeds.

Advantages
Highly effective against persistent weeds
Good compatibility with other herbicides
Continuous control, reducing the risk of weed recurrence

3. Quinclorac: Widely used on lawns.

Mechanism of action
Quinclorac is an auxin mimic herbicide that controls both grass weeds and some broadleaf weeds. This makes it one of the indispensable herbicides for lawn care and agricultural fields.

Recommended Reading: Fenoxaprop and Quinclorac

Quinclorac Herbicide

Dual action: Inhibits both cellulose synthesis and growth hormone pathways.
Systemic conductance: Full coverage of key growth areas of target weeds through leaf and root uptake.

Targeted Weeds
Quinclorac is particularly good at fighting the following weeds:

Gramineous weeds: Crabgrass, Foxtail
Broadleaf weeds: Clover, Pigweed.

Areas of application
Lawn care: to clean up Cricketgrass and other weeds and to restore uniformity to the lawn.
Farming: Selective control of weeds especially in rice fields.

Advantages
Dual effect against grass weeds and broadleaf weeds
Longer soil residual activity
Provides long-lasting weed suppression

4. Herbicide that contains 2, 4-D, dicamba, and quinclorac

Why choose a blend?

A blend of these three herbicides provides comprehensive weed management through different mechanisms of action and target weed spectrums:

Expanded Target Spectrum:

2,4-D and Dicamba specialize in broadleaf weeds.
Quinclorac makes up for the lack of grass weeds, especially cricket grass and dogwood.

Synergy:

2,4-D and Dicamba combine to provide fast-acting broadleaf weed control.
Quinclorac complements long-acting grassy weed suppression.

Resistance Management:

The combination of three different mechanisms of action reduces the likelihood of weeds developing resistance and ensures long-term weed control.

Optimal application scenarios
Lawn Maintenance: Eliminate broadleaf and grass weeds, keep the lawn neat and beautiful.
Agricultural crop management: Especially suitable for 2,4-D and Dicamba resistant crops such as corn and soybeans.
Non-cropland management: such as roadside slopes and parks, providing broad-spectrum, long-lasting weed control.

Advantages of the blend
Greater broad-spectrum: Controls broadleaf weeds (e.g. dandelion, ragweed) and grassy weeds (e.g. cricket grass).
Efficient systemic: the combination of the three enables rapid penetration and full coverage of all growing areas of the weed.
Flexibility: Suitable for a wide range of environments such as lawns, agricultural fields and non-cultivated land.

5. Precautions

Climatic conditions:
Avoid applications in strong winds and hot weather to minimize drift and evaporation losses.

Tolerance Tests:
Prior to mixing and applying, it is recommended to conduct a small scale test for crop tolerance to ensure safety.

Environmental Protection:
2,4-D and Dicamba are volatile in the environment and applications should be avoided near sensitive crop areas.

Summarization

The blend of 2,4-D, Dicamba and Quinclorac represents not only an advancement in modern weed control technology, but also a new tool for agricultural producers and lawn care professionals. The combination of the three provides significantly more efficient weed control and broader coverage, while also reducing the risk of resistance.
