Broadleaf Herbicide Types

Since the class of broadleaf weeds is so diverse and immense, broadleaf weed killers come in various categories. So it is essential to analyze your requirements and buy the best broadleaf weed killer for those needs.

Broadleaf Weed Killer

Post-Emergent Broadleaf Herbicides

As the name suggests, post-emergent herbicides target lawn areas with already existing or grown broadleaf weeds. You can use them at any time when weeds have emerged above the ground. Post-emergent herbicides work best in cold temperatures, early spring, or fall season.

Meanwhile, applying in dry and hot temperatures can damage the turf and won’t be as effective. Such weed killers are most suitable for annuals (which live for a year) and perennials (which come back every season).

Post-emergent are of two basic types; contact and systemic herbicides. Contact herbicides are suitable for smaller weeds as they do not attack the roots. Since they kill the weeds once a season, they can work as the best broadleaf weed killer if your garden is infested by winter or summer annuals.

Systemic herbicides are more potent as they translocate through the entire root system of the weed. Larger weeds and perennial broadleaves are the most suitable prey of systemic herbicides.

Pre-Emergent Broadleaf Herbicides

Popular as a preventive measure, pre-emergent weed killers halt the growth process of broadleaf weeds and work wonders on annuals like chickweed. However, there’s a catch. Pre-emergent herbicides need to be applied at a particular time to ensure maximum productivity. It’s crucial to target the weeds at a very early germinating stage based on the sprouting pattern of the particular weed in your lawns.

Selective vs. Non-Selective Herbicide

The difference between the two is pretty straightforward. It is essential to know the type of weeds in your garden if you’re using a selective herbicide. Otherwise, non-selective herbicides will get the job done in the case of multiplying broadleaf weed growth.

Selective herbicides are manufactured with certain chemicals and products that target weeds and unwanted herbs. Such chemicals don’t cause any damage to grasses, vegetables, trees, and other plants. A particular example is 2-4-D, a synthetic chemical acting on the growth regulator of weeds.

On the other hand, non-selective herbicides are highly toxic and destroy everything in their way. Since they fail to differentiate between weeds and grasses, they also damage ornamental plants and vegetables. Therefore, it is essential to clear the lawn space before application to prevent unwanted damage. Non-selective herbicides are best suited for large infestations and tougher perennials.

Broadleaf Spray vs. Granules

Different marketing brands specialize in different product packaging for the best broadleaf weed killers. The real debate- which of these is the most effective choice?

It all comes down to your ease and preference, but we have reason to believe that liquid sprays top the list. Liquid sprays are easy to use and coat the tiniest surfaces of leaves. Often you need to dilute liquid concentrates to apply an adequate amount of herbicide.

Granules or dry pellets are suitable for broad-base application to tackle the entire lawn or garden. On the downside, granular weed killers lack effectiveness because they require the soil to be damp and moist for good absorbance.

Weed killer granules are often so tiny in size that they demand tact and skill for sticking to the leaf surface. However, some gardeners might prefer dry granules because liquid sprays can damage surrounding plants.

Synthetic vs. Organic Broadleaf Herbicide

If you are confused about choosing either synthetic or organic broadleaf killer, here are a few things to consider.

Synthetic Broadleaf Weed Killer

Synthetic herbicides are composed of chemical compounds that are highly effective and strong in action. However, their toxicity poses serious health risks to both humans and pets.

2-4-D Broadleaf Weed Control

2-4-D, also known as 2-4 Dichlorophenoxyacetic acid is the principal constituent of the best broadleaf weed killers. It is a plant growth hormone auxin that kills unwanted weeds like dandelions, clover, crabgrass, chickweed, etc. It is a top choice for persistent and pesky weeds because it poses no detrimental effects on the grass.

Organic Broadleaf Weed Killer

Organic broadleaf weed killers are mainly natural compounds such as cornmeal, acetic acid, citric acid, clove oil, cinnamon oil, etc. These ingredients don’t change soil pH or pollute the water, thus being ecologically friendly. Their most significant advantage is that they don’t contain toxins; however, their efficacy is less than synthetic ones. This is the primary reason for their lack in the market. Organic weed killers are best suited for annuals and not perennials.


Buying Guide: Best Broadleaf Weed Killer

Choosing an ideal broadleaf weed killer can be a nightmare with so many options available. So, what exactly should you be looking for?

Manufacturer

For the best broadleaf weed killer, your priority should be to opt for top-rated manufacturers. Experience counts and veteran manufacturers have had years of practice making pesticides and herbicides. Their extensive knowledge ensures premium products are manufactured to ensure the best experience for the consumer.

Composition

As simple and effective it is to use weed killers, the ingredients can be dangerous. They can pose harm to your pets, health, as well as the surrounding environment. Thus, you should be cautious while buying products that contain a large amount of glyphosate as it’s harmful to the environment.

Instead, You should consider other, safer options like 2-4-D Amine acid, which sets the bar high in effectiveness and safety. Also, be wary of selective and non-selective herbicides and choose what’s best for your lawn.

Ease of Use

Another vital part of purchasing a good quality broadleaf killer is user-friendliness. There are multiple ways you can apply herbicides to weeds in gardens. Most pesticides are designed to be used with a spray or spreader. The weed solution is diluted, making it simple for users at home to apply to any desired location.

Coverage

As tempting as it is to reach for the largest canister in the aisle, bigger doesn’t necessarily mean better. First, buy a sample and experiment with it to see if it’s the right choice for you.

Weeds can grow in many different areas, whether it’s in the center of your manicured lawn or around other plants, trees, and shrubs. Keeping this in mind, consider the intended area of use depending on the total square footage of your garden space.

What are Broadleaf Weeds?

As the name suggests, broadleaf weeds are weeds with broad, wide leaves and come in several shapes. Different herbicides are used to control and kill them. It is necessary to get rid of broadleaf weeds as they suck the nutrients and water out of the soil a lot faster than regular grass can. This can be problematic as lack of nutrients in soil attracts pests and disease.

Examples of Broadleaf Weeds

Now, there are several types of broadleaf weeds out there, but the main ones to watch out for are:

Chickweed

Chickweed, also known as Stellaria media, sprouts annually in the winters and withers away in the summers. Chickweed usually grows to 4-12 inches and has small egg-shaped leaves. Although this weed is edible, that doesn’t mean it is beneficial for your lawn. They grow in big clumps on empty spots in lawns and, like all weeds, prove harmful for the vegetation present in the lawn.

Clover

Even though possessing the four-leaf clover is considered lucky, having a cluster of clovers in your garden is quite the opposite. Getting rid of clovers is difficult as they are stubborn, perennial weeds; thus, they expand through seeds and vegetation. Even a tiny stem or root can lead to the growth of a new clover plant in another part of the lawn. This weed grows best in shallow, moist ground.

Dandelion

Dandelions are considered pretty as their general appearance is that of a flower. However, it is a weed with roots that extend deep into the soil, sucking out nutrients and water. Dandelions are perennial weeds like clovers and are pretty tricky to remove. To remove a dandelion, they must be eliminated from the roots, or there is an imminent threat of re-growth.

Prostrate Spurge

The scientific name for this weed is Euphorbia Malculata, but it is commonly known as the spotted spurge. This weed takes up vast sections of a lawn with its broad leaves. It has oval leaves with a red stem running through them, giving it a spotty appearance. With a not-so-pleasing look, this weed can also cause skin irritation on human skin, so you must be cautious while dealing with it.

Prostrate Knotweed

The prostrate knotweed has many names, including common Knotgrass, low grass, bindweed, pigweed, and the polygonum aviculare. It is a summer annual and goes away during October. Because it can spread quickly, it must be removed when you first catch a glimpse of it.

Broadleaf Weed Control

Knowing the basic principles of broadleaf weed killers is essential to bring the best out of them. Whether you’re a hobbyist or a professional, you must know how to use and apply the herbicides to target the weeds at the right time. Numerous things need to be kept in mind when applying broadleaf herbicides.

When To Apply Broadleaf Weed Killer

First, you should consider the type of weed and the season of emergence. If the weeds haven’t fully emerged, pre-emergent herbicides need to be used at the right time based on geographical location and growth seasonal patterns. Of course, it all depends on the type of weed. Clover, for example, should be gotten rid of in spring, whereas chickweed in fall or early winter.

If the weeds have already emerged, post-emergent herbicide needs to be applied as soon as possible. The quicker you apply, the less likely are the chances of multiplication. Weeds tend to be invasive and quickly spread out over a short time. Hence, keep spraying whenever you spot a new appearance.

Since weeds pop up seasonally, the best and most efficient way is to get rid of them strategically. Weeds that appear in winters should be taken care of in fall, and those that show up in summers should be gotten rid of in spring. This ensures early elimination and makes sure that you’re not wasting all your time, money, and resources on getting rid of stubborn seasonal weeds.

Best Time To Apply 2-4-D

A few tips to give it your best is to make sure the weather isn’t hotter than 90 degrees Fahrenheit yet is greater than 60 degrees Fahrenheit. The spraying should be done with no wind (less than 5mph) and should be applied at least 2 days after you’ve mowed your lawn. Not immediately.

Another thing to remember is that you shouldn’t use the product after rain or before rain is forecasted. Applying 2-4-D on water and weeds will dilute the herbicide, consequently decreasing the effectiveness. Water and dew can prevent the chemical from reaching the weeds, wind can evaporate the product, and rain can wash it away before it even gets a chance to work its magic.


Final Thoughts

To sum up, with the best broadleaf weed killer, you can put an end to annoying weeds and allow other plants in your lawn to flourish. We hope our 8 best broadleaf week killer review list and buyer’s guide have armed you with valuable information.

Happy weed killing!

FAQs

How do you get rid of broadleaf weeds?

You can get rid of broadleaf weeds manually, but why go for such a tedious task when an easier alternative is available? Broadleaf herbicides have overtaken the market owing to their high success rate. All you have to do is measure the square footage of your yard and spray the herbicide.
Most herbicides require dilution by adding water as per the instructions. You can also add a surfactant for more absorbance and better sticking on the leaf surface. Spray the herbicide on the leaf surface by avoiding contact with other woody plants or trees. Within a few weeks, the results will be right before your eyes.

How do you get rid of broadleaf weeds naturally?

Harsh chemicals are not the only way to get rid of weeds. If you want to approach a natural and safer way, simply mix vinegar, salt, and liquid dish soap. Vinegar being acidic alters the environment of the weeds. Salt is excellent to kill the weeds along with lawn edgings or sidewalk cracks.
Other than this, corn gluten meal, a byproduct of the corn milling process, prevents weed seeds from germinating. It can be applied if you’re familiar with the growth patterns of weeds in your lawn. However, it doesn’t help you with weeds that have already sprouted.
And yet, the simplest way to get rid of broadleaf weeds is to pour boiling water on them. The heat from the boiling water will wither the weed. This is particularly useful for weeds that pop up in the sidewalk or driveway cracks.

Does weed and feed kill broadleaf?

Weed and feed consist of herbicides that kill weeds and fertilizers that support grass. Most weed and feed products include a poor fertilizer with little nutritional value and herbicide Dicamba which requires multiple applications for a satisfactory result. This is why they aren’t the best solution.
However, few weed and feed products are strong enough to provide a simple solution with short-term effectiveness. They serve a dual function by killing broadleaf weeds and fertilizing your lawn for a dense and lush appearance.
