  • Weighty

Removing the pesky weeds such as clover and dandelions is usually a complex task. However, to make this task easier, the Ortho brand has introduced a 0430005 B Gon weed killer.

However, before using, make sure to use all the Ortho brand directions to prevent any harm to the grass. With this weed poisons formula, you can kill over 250 different weeds in no time. You can know the complete list of weeds that this formula can remove through the label.

This extended coverage makes it an ideal solution for large places and longer usage. In a few hours, you will notice a significant improvement after applying this weed killer.

At first, you will see the weeds’ leaves getting curled. Within a short period, this formula turns the leaves of the weeds to brown and wilt. After 2-3 weeks, it will burn the whole weed. You may also need a second application for some types of weeds.

The second application of Ortho weed killer is recommended if you do not notice significant results within a few weeks. Like other top-notch weed killers, this one also becomes rainproof quickly. It becomes waterproof only after one hour of application, so that should be an additional reason to try Ortho weed killer.

Additionally, this herbicide for lawn is selective, meaning that you can target any affected areas as required. With it, you will get much better control while killing undesired weeds and grass. However, adding a few drops of this formula to the plants can cause them to burn. Therefore, it is advisable to keep it away from plants you want to save on your lawn.

I will also suggest you read the product label before using it, as the label includes some vital information that every user should know. Keep the Ortho weed killer away from the reach of kids and pets. If you have some pets or kids at your place, keep them away from the area where you applied this weed killer.

Buying Guide

As of now, you are familiar with some of the top-quality weed killers present in the market. You might think about the factors that you should keep in mind while shopping for these weed killers.

But before letting you know about these factors, I will make you understand the benefits you will get from using the weed killer.

  • The prime advantage of a weed killer is that it will help you control the weed
  • You can get much quicker results by using a weed killer
  • As compared to other weed-killing approaches, the weed killer is one of the easiest
  • You do not require experts to utilize the weed killer
  • The weed is prevented from growing for an extended period with this product

You should consider the following factors when choosing a weed killer before purchasing.

– Capacity

The first thing to check is the capacity of the weed killer. For more area and better coverage, try using the weed killer with a greater capacity. However, if you have weed over a small area, you can also buy a small size container containing the weed killer solution.

Also, check whether the product is strong enough to kill an unnecessary weed or not. With a strong formula, you can quickly get the work done.

– Selective or Non-Selective

Mainly there are two types of weed killers that you will find in the market.

The first one is selective, and the other is non-selective. With the help of a selective formula, you can target any particular area. If only a small portion of your lawn is affected due to the weed, then try picking a selective formula.

On the other hand, the non-selective solution leaves its mark on everything it touches. The non-selective option is ideal if you have to deal with a large area affected by the weed. It will help you quickly cover more areas and deliver an effective outcome.

– Types of Weed

Not all weed killers are capable of eliminating all sorts of weeds. Some of the weed killers for lawn only target a specific type of weed. Therefore, before buying a weed killer, ensure that it has the capacity to kill the weed that you want to remove from your lawn.

– Concentrated or Ready-to-Use

There are two distinctive types of form in which the weed killer comes.

One is the concentrated form, and the other is ready-to-use. A concentrated form is usually a strong solution, due to which you will have to mix it with water.

Directly applying the concentrated form can damage the lawn. Therefore, try mixing the accurate ratio with the water as recommended by the brand. Besides, in the ready-to-use formula, you do not have to mix anything.

You can directly use it in the affected area and get the output. Depending on your need, you can either select a concentrated or ready-to-use formula.

– Rainproof

The rainproof of a weed killer means that it will not get affected by the rain. Most brands do not suggest applying the weed killer on a rainy day because the rain might not allow the formula to work properly. But if you live in an area where it is hard to predict the weather, then go for a product that becomes rainproof quickly. It’s no surprise that most weed killers are rainproof after only a few hours.


If you still have not decided and are confused about the product you should choose, do not worry. The three of the best weed killers for lawns that I will suggest you select are Ortho WeedClear, Roundup Ready-to-Use, and Southern Ag Amine 2,4-D weed killer.

All of these weed killers are in liquid form, making them easier to apply. You can use a spray to apply these solutions to the desired area within a short time. Apart from these three recommendations, the other reviewed products are also worth buying.
