Organic Vs Synthetic Weed Control

The BEST Weed Killer for LAWNS // PRO VS. CONSUMER Weed Control…

The term organic is an unofficial, lightly regulated word that references something natural. It involves using ingredients present in nature to make an herbicide with similar effects as its man-made chemical or synthetic counterparts.

Generally, organic herbicides are safer than synthetic weed control products. However, as Ohio State University reports, there are highly toxic organic lawn weed control products on the market. With that in mind, always exercise caution when selecting, using, and storing any weed control products, and read the label to familiarise yourself with all of the associated hazards that come with using these types of products.

Organic Herbicides

Organic herbicides range from homemade concoctions to pre-mixed, store-bought solutions. Homemade solutions are generally inexpensive, depending on whether you have the ingredients to hand or if you need to buy-in. Store-bought solutions are often pricier than their synthetic counterparts since they contain natural ingredients that are not mass-produced.


Organic varieties are generally safer to use in terms of causing harm to people and pets if spillages occur. This is because the ingredients they contain are mostly natural. Id strongly advise against ingesting any type of lawn weed killer however and always seek medical advice if either spillages or ingestion occurs.


Synthetic Herbicides


Weed Killer Buyer’s Guide

Things you should consider before buying weed Killer

The wide array of weed killers available in the market can be quite confusing. For homeowners, it can be an overwhelming experience choosing from numerous brands and types of weed killers currently available compared to a few years ago. Regardless of whether you are planning to use an organic or chemical product, there are still different formulas that you need to check out before making a purchase.

Selective vs. non-selective

Non-selective weed killers are developed to control a broad range of weeds. These are the weed killer that kills everything.

Whereas selective weed killers are made to control specific weed types.

Pre-emergent and Post-emergent

There are two types of herbicides used for different growth stages of the weed, Pre-emergent, and Post-emergent.

Pre-emergent weed killers are used to prevent weeds from sprouting altogether. However, post-emergent weed killers are to be used after the weed has developed.

Contact and Systemic weed killers:

Contact weed killer affects only the foliage and the green parts of the plant, but does not get absorbed into the roots. Therefore, new growth can resume before any plant damage has occurred. Because they are not systemic, contact-type weed killers must be applied at least three times a year to accomplish satisfactory control of established plants in a lawn or garden.

How Long Does Weed And Grass Killer Last

Most weed killers evaporate or break down in the soil within 24-78 hours. If the weed and grass killer was still present in the soil, you wouldnt be able to grow anything.

Its safe to plant anything in a spot where you have sprayed weed killer after three days. However, if you want to be extra sure, you can wait a couple of weeks before planting.

Most herbicides are required by law to disappear within weeks, if not sooner. Glyphosate, on the other hand, stays in the soil longer than initially thought, up to at least a year.

The International Agency for Research on Cancer categorized glyphosate as probably carcinogenic. It can also affect your kidney and liver. Therefore, avoid this herbicide.

What You Need To Know Before Using Weed Killer

I know this is pretty trivial but the ultimate trick with weed killer is to carefully follow the instructions and BE PATIENT. Almost all systemic weed killers will take a while to work because the Glyphosate is absorbed into the leaf and then needs to travel to root tip in order to completely kill the weed. It will take up to a month but can be quicker and generally depends on the conditions. Never be in a rush and have a timed plan to keep things safe. The longer you leave to plant after application the better and seven days is the minimum.

Choosing A Lawn Weed Killer

When deciding which is the best weed killer for your lawn, its imperative you understand how weed killers work.

This can get pretty involved and complicated, says Senior Turf Specialist Joe Churchill at Reinders Inc. In the simplest terms, Churchill says, The active ingredient in many of them literally accelerate growth, and the weeds grow themselves to death.

Theres no one-size-fits-all solution to lawn weeds. So its essential you choose a selective herbicide specific to the type of lawn you have, as well for the kind of weeds you want to kill. Local nurseries will only sell products intended for use in your region.

When buying online from big box stores, be sure to check that the products are suited to your climate, grass and weeds. Keep in mind that non-selective herbicides will kill everything in their wake, including your grass.

Breaking it down even further, the type of weed killer you use depends on whether you are treating:

  • Preventively or
  • After germination occurs .

Applying a lawn weed killer should be timed based on how the active ingredient is designed to work and under which conditions.

A pre-emergent herbicide intended for use to control crabgrass will be applied at a different time than a post-emergent herbicide intended to be used to kill clover or dandelions, Churchill says. Whats more, even the timing of a crabgrass pre-emergent herbicide will vary by weeks depending on regional climate.
