What to look for in a weed killer

To get a good weed and grass killer, the following are important factors to consider.

1. Active ingredients

Every brand comes with a different set of active ingredients targeting a specific types of weed. Before you make a purchase, be able to know the types of weeds or grass you want to target. While there are products that kills every plant they come into contact with, we also have those that target a specific species of weed.

Products come with a list of weeds they can tackle. Read the list and instructions on how to apply for an effective outcome. Going through product reviews can also be helpful in achieving this objective.

2. Selectivity

Herbicides can either be selective or non-selective. Selective herbicides target specific plants without affecting others. They are the best to use when you want to protect desired plants.

Non-selective weed killer tackle any type of plant it comes into contact with. They are ideal for clearing weeds from a large area or spaces you completely don’t want to see any plant. Non-selective herbicides are the best for eliminating weeds on driveways, patios and walkways.

3. Application

Various brands of herbicides come with different methods of application which include the following:

Trigger spray application: They are usually ready to use formulas that has a gun-like spray bottle. The solution is sprayed directly on plant leaves or foliage without mixing with water or other solutions.

Pump applicator: The herbicide may be a ready to use solution or a concentrate that may require mixing before spraying. You require a sprayer tank to apply especially when you are dealing with large coverage.

Granules: Weed killers may also be available in form of powder or crystals which are applied without dissolving them and followed with splash of water. This helps the granules to penetrate and dissolve into the plant.

4. Quantity

Large areas such as driveways require relative large quantity of an herbicide. You may also require a pump sprayer for faster application. The best type of weed killer for such a case is a concentrate that can be diluted to have more quantity which is then applied using a sprayer pump.

For small patches of weeds or undesired grass, go for a ready to use weed terminator which usually comes with an applicator. Granulated herbicide may be used for both small and large spaces without much problem.

5. Residual activity

Residual activity defines how long the formula can remain active after application. Driveways, patios and walkways require herbicides with high residual activity. These are spaces you don’t need to see weeds growing at forever.

Low residual activity herbicides are ideal for lawns, gardens and landscapes when you intend to grow your desired crop. These type of weed killers can be replant – applied before planting, pre-emergent applied before germination or post emergent – applied on grown weeds.

6. Safety

Commercial weed killers require high levels of precaution when handling them. Most of them are noxious, inhaling or ingesting them can be dangerous to one’s health. Key safety measures include:

  • Wear protective gear to avoid contact with your body
  • Do not spray while kids, pets or other family members are around
  • Properly dispose of empty herbicide bottles or containers
  • Store away from the reach of children.
  • Do not spray on edibles such as fruits, vegetables
  • Always read and follow label instructions before using

If you cannot safely handle a chemical weed killer, involve a professional weed control service or consider other natural ways of getting rid of weeds between pavers and cracks in your hardscapes.
