Intro: What are Herbicides and Why Do We Need Them?

Ever since the beginning of modern day farming techniques, people have been finding new ways to help crops and plants grow. The use of herbicides, also known as weed killers, is just one example of a technique that has been used worldwide to counter weeds along with other plants or fungi that could affect crops. Herbicides are in fact so common that even everyday homeowners and gardeners can now use these to kill potentially harmful plants or nuisances to their garden. One such nuisance that is commonly killed using herbicides are dandelions.

Dandelions are a type of plant that is found across the world and is one of the most common weeds to find in a garden. The reason why dandelions are considered a nuisance is because of how fast they can grow and spread across a garden. Dandelions are also stubborn to kill and don’t die from just being cut or pulled out of the ground. It’s important to kill dandelions before they spread because they steal important nutrients your plants need to grow and if left unchecked, can easily overwhelm your garden.

In this article we’ll be covering one of the best ways to use herbicides to dandelions, namely, a spray, along with the basics of herbicide sprays and how to use them effectively. More on that down below.

Dandelion Killer Sprays Buying Guide

Sprayer Types

Using a spray is the most effective and common method of spreading herbicides. Here are some of the most common types of sprays that are used to spread liquid herbicides.

Sprayer Types

Hose Connector Type Sprayer

A hose connector type sprayer is the most efficient method to spread herbicides in gardens or lawns. Instead of using air pressure to pump the chemicals out of the bottle (like trigger style sprays), these types of sprayers combine that mechanism and add a twist to it.

Rather than spraying the herbicide directly out of the bottle, these require the use of a water hose where the chemical mixes in with the water as it is pushed out the nozzle. This is a more efficient method because less herbicide is wasted in a single spray and the water also helps coat the unwanted plants in the herbicide. The water also helps the herbicide seep through the soil and reach the roots faster. 

Wand Type Sprayer

Wand Type Sprayer

Wand type sprayers have the most reach and accuracy. Wand type sprayers get their name from their long and thin shafts that narrow down the spread greatly and lets users spray directly on the unwanted plants instead of a cone. Wand type sprayers also often come with a half sphere shield that covers the nozzle and prevents any herbicide from accidentally getting on to nearby plants.

This is a great method for getting rid of weeds that grew close to other nearby plants that you don’t want affected by the herbicide. This can be used for weeds that grew in a vegetable patch or flower bed. Wand type sprayers are also quite efficient since they’re used for more precise spraying rather than for covering a large area.

Trigger Type Sprayer

Trigger Type Sprayer

Trigger type sprayers are arguably the easiest to use and resemble and function the same way as a normal spray bottle. Trigger type sprayers can be used on small to large volume bottles and are pretty straightforward. They work using a small tube that extends down into the bottle and the trigger.

When the trigger is pulled, a suction is formed in the tube that sucks up the contents out of the nozzle. Complementing this simple mechanism is a versatile nozzle. Trigger type sprayers commonly have an adjustable nozzle that gives users the option to choose from different spray patterns such as mist, stream or a cone. This lets users accurately spray herbicides directly at a singular weed or apply a fine mist in an area with herbicides.

Types of Herbicide

Organic

Organic herbicides use chemicals that are naturally occurring in the environment. Organic herbicides are more environmentally friendly and less harmful to people or pets that might ingest it accidentally. Organic herbicides dissolve faster in the soil and can act just as fast as some chemical herbicides. The downside is that organic herbicides tend to be short lived and are not as effective at keeping weeds from growing again. Some organic herbicides require frequent applications on weeds because of this. At the same time, this isn’t necessarily a bad thing because organic herbicides tend to be less harsh on the soil. Examples of organic herbicides are vinegar, essential or fatty oils, citric acid or D-limonene. 

Chemical / Inorganic

Chemical herbicides are a wide range of chemicals used to kill or regulate the growth of plants. These are usually synthetic (man-made) chemicals that are made in labs and have seen use in farms and households across the world. These include Glyphosate, Atrazine, Paraquat and Endothal just to name a few examples. Some of these chemicals are so potent that only a few drops are required to kill a plant which is why most of these chemical herbicides are mixed with water before application. Chemical herbicides are also pretty good at preventing the growth of weeds because of how long they can linger in the soil. The dark side of chemical herbicides is that they have a long history of affecting the users health because of how effective they are. That’s why chemical herbicides come with warning labels and specific instructions on how to use them to prevent any adverse health effects.

Selective & Non-selective

As you can imagine, a substance designed to kill all plants it comes into contact with isn’t very picky on what it kills. Herbicides have gone through a long history of trial and error ever since they were first introduced and many improvements have been made or discovered. One such improvement is that some herbicides are now designed to only target specific plants rather than everything green. So how does this work? 

Well, it’s pretty simple. Some plants are simply more affected by certain chemicals than others. Manufacturers have spent years researching just what chemicals kill plants like weeds but spare desirable plants like crops or grass. Most manufacturers have a list that comes with the herbicide or on their websites that users can access to determine just what plants are affected by the herbicide. If you’re looking to buy herbicides, it’s essential that you act responsibly and buy the right herbicide based on what plants are currently growing in your lawn or garden. Otherwise, you could risk killing more than just annoying weeds.

Important Factors to Consider

Result Time

Result time refers to how long it takes for the herbicide to be visually clear that it’s affecting the plant. Herbicides take effect immediately upon contact with the plant. You may not just realize it yet. That’s why manufacturers include this detail to give the users an estimate on how long till the plant fully dies. This can be in the form of the leaves of the plant drying, dying or shriveling up. The time it takes for the results to be visible by the user depends on a couple of things. For one, it depends on the potency and amount of herbicide applied. Another factor could be how deep the roots are of the plant and what type of soil is used. Typically, the results of the herbicide should be visible in an hour upto a whole day after the first application.

Volume

This measurement is used to determine how much herbicide is in the container. The volume of a weed killer can be measured in how much square feet of material is in the bottle. This is shown in sq  ft for short. Users can buy as much as a couple of gallons worth of herbicide or as little as less than a liter depending on how much is needed. If a gallon of herbicide sounds like overkill to you, some users intentionally buy large amounts of herbicide for long term use over the course of months or years potentially.

Lawn Size

The size of your lawn is another important factor to consider when shopping for herbicides. Specifically how much herbicide you should buy. For small to medium sized lawns, you can get by with a couple of liters or a gallon of herbicide quite easily since you won’t be using it that often. For larger properties, you’re probably going to need a gallon or more depending on how many weeds need killing per session.

Water &  Sunlight Proofing

Whether the herbicide is waterproof or not is an important factor to consider because the last thing you’d want is for the herbicide to be spread or splashed on to nearby plants that you don’t want killed. Some herbicides are quickly absorbed by the soil or roots of the undesirable plant and don’t run the risk of getting washed away or absorbed into the water table. Sunlight proof herbicides on the other hand, are herbicides that are made to withstand a certain temperature and UV light. This makes these herbicides more effective in warmer climates and less likely to be nullified by sunlight.

Other Plants

When applying any herbicide to an area, you should always take into account other nearby plants that could be affected. This highlights the importance of using the right sprayers to minimize the spread of these herbicides to the rest of your garden. You could further minimize the threat to your other plants by reading the list of plants that the herbicide is effective against and if your plant is on that list, you should take extra precaution when spraying. There are some sprayers that are more accurate than others such as wand type sprayers that you can use to spray directly on weeds. Another way to protect other plants from the herbicide is to make sure there’s no rain forecasted in the next couple of hours after spraying. Rain could potentially wash away the herbicide or worse, spread it to other plants.

Safety Tips

Herbicides are potentially dangerous to your health and that of your kids or pets. It’s essential that you take all the precautions that you can when using herbicides. Here are a couple of tips you can use when spraying herbicides around your garden or lawn.

  • Use gloves. Some herbicides can cause rashes or allergic reactions if it accidentally gets on your skin. You could use rubber nitrite or gardening gloves to give yourself a layer of protection.
  • Wear a mask and goggles when spraying herbicide in a mist. Some sprayers have nozzles that use a mist function to evenly spread the herbicide. These small particles can be easily inhaled or land on exposed eyes and depending on the chemical, can cause health issues such as blindness or even cancer.
  • Keep your pets inside. Before spraying around the garden, make sure your pets are safely in the house. While there are some herbicides that are pet safe, most are not. Pets such as dogs can easily get the herbicide on their fur or inhale it when sniffing around the garden. This can make them very sick.
  • Be wary of nearby people. Herbicides typically have a very strong smell and can easily affect people nearby, especially kids. Be sure to only start spraying when there’s no one else nearby.
  • Make sure the herbicide is safe to use near edible plants. This applies for herbicides used in vegetable patches or near fruit bearing trees. Some herbicides can be absorbed into fruits and vegetables, potentially making them unsafe to eat.

FAQs

Q: How safe are herbicides?

A: While there are certainly herbicides that are safer than others, it mostly comes down to how the herbicide is applied and if the instructions were followed properly. Herbicides have been used safely for decades across the world and will probably continue to be used for decades more. The bottom line is if you use these herbicides properly and responsibly, there should be no reason to worry.

Q: How much are dandelion killer sprays?

A: Herbicides are quite cheap to make. That’s probably why they’re use is so widespread. You could easily buy a gallon of herbicide for less than $50. 

Q: Why use a dandelion killer spray?

A: Herbicides are a great way to get rid of dandelions in a garden before they spread too much. Using a spray for liquid herbicides is one of the easiest methods for this task. Liquid sprays don’t require much preparation and most liquid herbicides come pre-mixed.
