Benefits of Using Pre-emergent Herbicide

  • Weed Prevention: Stops weeds before they can germinate and become a problem, reducing the need for post-emergent treatments.
  • Lawn Health: Allows your grass to grow without competition from weeds, resulting in a healthier, more attractive lawn.
  • Time-Saving: Reduces the time and effort spent on manual weed removal.

Types of Pre-emergent Herbicides

Granular Pre-emergents

Granular pre-emergent herbicides are easy to apply using a broadcast spreader. They are ideal for covering large areas uniformly and often include fertilizers to promote lawn health while preventing weeds. Granular options provide long-lasting protection, typically for up to 6 months.

Liquid Pre-emergents

Liquid pre-emergent herbicides are applied using a sprayer and offer quick absorption into the soil. They are great for targeting specific areas or treating uneven terrain. Liquid pre-emergents are effective against a broad spectrum of weeds.

Best Time to Apply Pre-emergent Herbicides

  • Early Spring: Apply pre-emergent herbicide when soil temperatures reach about 55°F (13°C) for several days. This is typically when forsythia blooms in many regions, signaling the right time to treat your lawn.
  • Fall: Apply in late summer to early fall before the first frost. This helps prevent winter annuals and early spring weeds from germinating.

Do Not apply pre-emergent herbicides if you are going to install grass seed. Pre-emergents will also sterilize grass seed and it will not be able to germinate. Check the label for reseeding times.

How Does Pre-emergent Herbicide Work?

Pre-emergent herbicides are a proactive approach to weed control, designed to stop weed seeds from germinating and growing into mature plants. Here's how they work:

Mechanism of Action

Pre-emergent herbicides form a chemical barrier in the soil that targets the early stages of weed seed development. When weed seeds begin to germinate, they absorb the herbicide, which disrupts essential processes necessary for growth. This prevents the weed seeds from developing into seedlings and emerging above the soil surface.

Application Process

  1. Timing: Apply pre-emergent herbicides before weed seeds germinate. This is typically in early spring and fall, based on soil temperatures and seasonal weed growth cycles.
  2. Soil Integration: After applying the herbicide, it needs to be watered in to move the active ingredients into the soil where the weed seeds are located. This can be done through natural rainfall or manual watering.
  3. Barrier Formation: Once integrated into the soil, the herbicide forms a protective barrier that affects weed seeds as they attempt to germinate.

Effectiveness

  • Broad-spectrum Control: Pre-emergent herbicides are effective against a wide variety of annual grasses and broadleaf weeds, making them versatile for different lawn types.
  • Preventive Measure: By preventing weeds from emerging, these herbicides reduce the need for post-emergent treatments and minimize the competition for nutrients, water, and sunlight that your grass would otherwise face.

Frequently Asked Questions

What is a pre-emergent herbicide?

A pre-emergent herbicide is a type of weed control that prevents weed seeds from germinating. It forms a barrier in the soil that stops the growth of weeds before they emerge.

When should I apply pre-emergent herbicide?

Apply pre-emergent herbicide in early spring and fall before weed seeds begin to germinate. Timing is crucial for effective weed prevention. For most areas, early spring applications should be made when soil temperatures reach around 55°F (13°C) for several days. Fall applications should be done when temperatures cool down but before the first frost.

Can I use pre-emergent herbicide on my newly seeded lawn?

It's best to avoid using pre-emergent herbicides on newly seeded lawns, as they can prevent grass seed from germinating as well. Wait until the grass is well established.

How do I apply pre-emergent herbicide?

Follow the product instructions for application rates and methods. Granular products are typically applied with a spreader, while liquid products can be applied with a sprayer.

Does pre-emergent herbicide control all types of weeds?

Pre-emergent herbicides are effective against many types of annual grasses and broadleaf weeds, but they may not control all weed species. It's important to choose a product suited to the specific weeds in your area. If weeds have already germinated, pre-emergent herbicide will not have any effect. It must be applied before germintation.
