There is no dearth of weed killers, a.k.a. herbicides, in the market today. You can choose one depending on what type of weed you intend to deal with. Basically, two types of weed killers are available in the market: selective weed killers and nonselective weed killers. While the selective weed killers specifically target a particular variety of weed without causing any harm to domestic plants in the vicinity, nonselective weed killers are known to kill all the plants―wild as well as domestic―that come in contact with them.
Of these two types, the nonselective herbicides are stronger, and are usually used to clear large tracts of land, like railway embankments or industrial sites. A third type, organic herbicides have been introduced of late. These herbicides, most of which are nonselective, are known to have very low toxicity for humans and animals, and very little or no residual activity. On the flip side, they are a little costly, and therefore, most people prefer to go with the other options.
Additionally, weed killers are categorized into two groups based on when they are supposed to be used: pre-emergence herbicides and post-emergence herbicides.
These herbicides are to be used when you expect weeds to crop up in your lawn. These are ideal for annual weeds, like crabgrass and goosegrass. You should ideally use them at the time of the year when weeds are likely to surface, or as soon as you notice the slightest sign of weed growth in your surroundings. If used too early, the chances are that they will be rendered useless by the time the weeds start surfacing.
These herbicides are to be used when you see considerable growth of weeds in your lawn. These weed killers are ideal for both, perennial and annual broadleaf weeds. Even though they can be used at any time after the weeds have surfaced, they are most effective when the weeds are relatively young.
Weed Killer Reviews
When it comes to weed control, timing is undoubtedly the most important factor. It is better to act as soon as you sense the slightest growth of weed in your garden as it can be quite difficult to deal with them once they start spreading. You can opt for chemical weed killers, which boast of being the best in the market, to get rid of these pests. In case you face difficulty in deciding which one to opt for, given below is a list of some reputable brands that you can choose from.

Bayer Advanced Natria Grass & Weed Killer
Being a nonselective herbicide, Bayer's Natria Grass & Weed Killer may not be ideal for your lawn, but it is by far the best bet when clearing considerably large tracts of land. It can be used to get rid of thistle, chickweed, dandelion, stinkweed, etc. It is also ideal for vines growing on fences and other standing structures. That it can be applied at any time of the year, is an additional advantage of this product.
While all these synthetic and organic herbicides are effective when it comes to weed control, you can even resort to ingredients readily available in your kitchen, like vinegar, bleach, and salt, to curb weed infestation. Simply spraying vinegar or bleach in your lawn can help you curb weed growth to a certain extent. While exposure to bleaching powder is generally considered harmful for humans, it will evaporate within the next few days, making your lawn as good as ever. Similarly, adding a pinch of salt at the base of unwanted plants can also help destroy them. That, however, will be a cumbersome task if you have a huge lawn.
It is important to note that some weed killers have toxic chemicals; therefore, they can be harmful for your domestic plants, pets, as well as for you. The risk involved is most when the herbicide is not used as directed or when the same is used in excess. Taking that into consideration, it is wise to follow the instructions carefully and, more importantly, resort to protective gear (like goggles and gloves) and a good spraying device when using these herbicides.
