Types of Weed Killers

The two common examples of weed killer categories include the selective and non-selective categories

  • Selective weed killers – these products are used to target a specific kind of plant-specific. If the product eliminates broadleaf plants, then they are less likely to affect narrow-leaf grasses. Thus, it’s the kind of product you will apply to gardens infested with dandelions or clover. A great example would be the Southern Ag`s Lawn Weed Killer, which you can use to target broadleaf weeds.

  • Non-selective weed killers will remove any plants they get in contact within your garden. You have to practice caution when applying such weed killers, especially over garden plants. You can use such products on walkways, but avoid applying them directly to your garden.

The weed killers also classify in relation to the amount of the plant they can affect. The common classifications include

  • Contact weed killer – these types will penetrate the foliage of a weed, but will not compromise the root system. More so, these types won’t affect the surrounding soil area.

  • Systemic weed killers – these types will penetrate the root system of the plant, and eliminate every aspect of the plant

  • Residual weed killers – these types will stay in the oil and kill any plants that grow on the ground for a few years. They are best used in locations where you don’t want any plants to grow, such as on sidewalks or driveways. 

The weed killers also classify as organic or chemical weed killers:

  • Chemical weed killers – these involve the use of chemical products such as Glyphosate, which will affect the photosynthesis process of a plant. More so, these products can kill the plants with just a single application or several, especially when it’s a perennial plant.

  • Organic weed killers – these types are common among various kinds of gardeners because they target the metabolism of a plant. A good example would be Pulverized Ammonium Nonanoate, which classifies as a soap salt. This product will help control the growth and development of weeds in your garden. It breaks down soil quickly, and will not have adverse side effects on the environment.

Important Features Of ​Dandelion Killer

Weed growing cycles – being able to kill weeds largely depends on their growth cycles. Killing the foliage of a weed might require several applications, especially in relation to the growth of the weeds. Here is an introduction of the types of weed you may come across: 

  • Annuals – these types go through their complete life cycle in one year. This is ideal because the plants won't grow back unless seeds and cuttings remain for the growing season next year. A good example would be crabgrass, which is an annual plant. That said, even if the plant dies in as little as one year, they often leave behind thousands of seeds. Thus, it's good to apply a product that will linger on the ground for several months. 

  • Biennials – the biennials refers to plants that grow after every two years. The biennial plant will grow roots and leaves in their first year. During the winter season, they become dormant and will produce flowers or fruits in the oncoming year. Common plants that fall under this category include common mullein, evening primrose, and more. 

  • Perennials – these are the types of plants that have more than two years of life span. They leave behind roots in the ground and grow back each year. The plants classify under two categories, the simple and evergreen perennials. The simple perennials spread by seed and long roots. The evergreen perennials which maintain their leaves. 

  • Becoming rainfast – avoid using weed killers that can get washed off easily. Ensure that you apply weed killers when it's least likely to rain, or when you are least likely to water the plants. This term is referred to as rainfast because the rain can compromise the effectiveness of a herbicide on a plant.
