Pre-Emergent Pesticides: The Correct Way To Kill Your Lawn’s Weeds

Here’s the bottom line: Pre-emergent herbicides are essential to lawn weed-control efforts. You must apply it correctly.

All summer long, you stared at these patches of crabgrass angrily. This spring was a difficult one. There were so many dandelions that the breeze blew them away, it almost looked like snow.

Never again, you vow, and go to the garden store for weed-killer … only to find a massive array of confusing herbicide choices.

Here’s a story that will walk you through the main classes pre-emergent herbicides. The pre-emergent product is applied to your lawn and fights weed seeds from ever growing. The University of Georgia Extension Service has a guide for weed control. Although they do not eliminate every weed in the lawn, pre-emergents are very effective at controlling many common weeds. These are the top four choices:

Spring Herbicide Application

The spring pre-emergent herbicide application is used to stop summer annual weevils. The broad and grassy types of summer annuals include both grassy and fern-like weeds. For best results apply herbicides when the soil temperature is around 55 degrees or above for at least 36 to 72 hours (ideally this will be two weeks before seed germination). Most of the USA experience these soil temperatures between March and April. Consult your local county extension service to get up to date soil temperatures in your area. Here is a map that gives a good idea of when to apply in the part of the country you live in.

Two primary methods to use herbicides are liquid formulations and granules. Pre-emergent herbicides that are pre-emergent granules must be soaked in water. This is because the active ingredient has to reach the soil. The herbicide becomes trapped in the pre-emergent granule and is not activated until it is water. This is also true with liquid pre-emergent products because grass and other plants may trap the active ingredient keeping it from reaching the soil during the initial application.

Application for Fall Herbicide

Fall pre-emergent applications are designed to prevent winter annual weeds. They germinate in the autumn months. The timing of your application is crucial to stop winter annual weeds taking over your lawn. Fall pre-emergent herbicides are best applied in autumn, depending on the location.

One of the most widespread winter annual weeds is Annual Bluegrass (Poa Annua). It is an extremely hardy weed and can require several applications in consecutive years to be controlled. If soil temperature dips below 70 degrees (soil temp is about 50 degrees), fall weeds can germinate. The best time to apply is the when the daytime highs drop to the mid-70s for about three to five days in a row.

A preemergent application won’t last the following summer. Make a late spring or early-summer pre-emergent (see Spring Herbicide Aplicaiton Map).

The Best Herbicides for Fall

Because of its lowest rates of application, prodiamine (Barricade equivalent), is the best and longest-lasting.

Oxadiazon (a Ronstar equivalent) can be used as granular in all types of turf and ornamentals.

How Pre-Emergent Hebicide Works

Let’s take a look at three key principles for pre-emergent control to get an idea of the way pre-emergent functions.

Principle #1: Pre-emergent herbicides are designed to control germinating weed seeds.

Pre-emergent targets weeds which haven’t yet sprouted from soil. Pre-emergent should not be applied to weeds that are visible from the ground. This will ensure the highest quality results, as well as avoiding unnecessary labor costs and time lost.

Important! Pre-emergent cannot be used to eliminate weeds and weed seeds.

Only when the weed starts to grow from its seed, and hits the herbicide barrier, will it be destroyed. You can leave seeds dormant so they don’t get harmed from the herbicide barrier. It is because weed control must be a continuous process. There will always be seeds under the surface and a portion will germinate each season. Large infestations must be controlled by applying annually.

Remember, pre-emergent herbicide can affect desirable plants. The same applies to turf. Pre-emergent must not be used in conjunction with seeding turf. Seed first, then apply pre-emergent at least 6 weeks later to allow for lawn establishment. Seed at the latest 3 months following application of pre-emergent.

Principle #2: For best results, the pre-emergent needs to be correctly mixed and spread evenly across the targeted area.

Pre-emergent herbicides need to be mixed correctly for the spray solution to be at the appropriate strength. Take the time to read the manufacturer’s recommendations and don’t forget to calibrate your sprayer!

Thorough coverage is key. Pre-emergents are like a blanket. They must cover all areas where the weed seed cannot germinate. As there are plenty of open spaces for the weeds to grow, spot spraying does not work. According to the manufacturer’s instructions, how much product you should use per 1000 sq. feet or an acre will be indicated. This determines how many gallons of water you need. It usually takes between 1 and 2 gallons to spray 1000 feet.

Principle #3: It is important to water in pre-emergent herbicides.

Top Pre-Emergent Herbicides for Lawns: How to Apply Pre-Emergents

No matter the type, weeds can cause havoc on any lawn. These unwanted weeds will not grow if you apply a preemergent herbicide to your lawn at the proper time.

In this article, I explain the basics of a pre-emergent and give a list of some of my favorite pre-emergents (alongwith the most appropriate use cases).

I like to think of weeds as cockroaches the ones that are noticeable are only the tip of the iceberg, and there are many more hidden just waiting for their right time to grow. These pesky plants have innate characteristics that let them spread easily.

They also compete for the space and water of your plants, which can lead to weeds becoming a nuisance.

As they continue to rob your favorable plants of their health, weeds also turn into the perfect hosts for disease and insects, allowing pests such as grubs to gain a foothold before your favorable plants take flight.

Getting rid of weeds after an infestation isn’t easy, and the best way to prevent them is by applying the right solutions before they even take root. Use the pre-emergent.

Pre-emergent herbicides, which are chemical options to keep weeds away from ever growing again, are specifically formulated to be effective against specific types and families of weeds.

Crabgrass Preventers: 5 Top Crabgrass Herbicides (Crabgrass Prior-Emergent Herbicides).

Crabgrass, an annual pest that can be difficult to control in spring and summer, should not be allowed to grow. You can find many different crabgrass killing products on the market. However, you should apply a mix of pre-emergent and post-emergent herbicides in your spring lawn care. This will reduce the need to use any additional herbicides. Controlling crabgrass is one the most important things cool-season lawn-care nuts do in order to maintain a healthy lawn.

When the soil temperature reaches 55 degrees, crabgrass seeds will germinate within three days. It is a good rule to remember that crabgrass germinates when the forsythia is in full bloom. If you don’t have the proper pre-emergent herbicides in place, crabgrass will still germinate until the ground temperature reaches 70 degrees. You should know when you apply crabgrass prevention. The best way to prevent crabgrass is to use a crabgrass stopper in the early spring. Prodiamine in early April in New England) and a second pre-emergent weed control application in early June. These herbicides create a vapor barrier which prevents crabgrass rooting.

There’s a number of different crabgrass preventers on the market, from granular to liquids. After trying different products for many years, I have finally created a top-five list of the best crabgrass preemergent herbicides.

This is why Prodiamine has become the most popular method of preventing crabgrass. This 50 lbs. Howard Johnson bag 0-0-7 Prodiamine 0,37% will cover 12,500 square feet ft. This product does not contain any other fertilizer than 7% Potassium. It is only used for transportation.

As soon as the soil temperature reaches 50 degrees, apply this crabgrass pre-emergent herbicide. For best results, water this herbicide with 1/2 inch of water right away. This has given me amazing results for all three seasons. I used it once in April, and my lawn was totally free of crabgrass. Because the turf hasn’t been pushed yet, it’s not ready for a crabgrass prevention with fertilizer (N–P–K). This is particularly true if your lawn was prepared for winter. You can use them for your second or third application.

Please note that there is a maximum annual rate of Prodiamine per calendar year. This chart is for those who plan to use it in April to stop crabgrass and fall to combat poa annua.
