A weed killer is a chemical agent for weed control and removal. Also known as herbicides, weed killers used in gardens and farms to control the spread of weeds. The reason weed killers are important in farms and gardens is that weeds often compete with plants for nutrients.

Keeping a good, clean, and healthy garden or lawn requires a good weed killer as weeds usually infested with fungus and insects that lead to stunted growth in normal plants and fruits. These unwanted plants are hardy and also tend to spread faster and have a longer life cycle than normal crops.

Weeds are essentially plants without any value that can deny important plants of necessary nutrients by using most of the nutrients for themselves. Also, check the buyer’s guide of best lawn mowers in India.

Buyers Guide – Weed Killers

The importance of a weed killer in garden and lawn maintenance cannot be trivialized. Its role in assisting to maintain a healthy, clean, and good lawn.

Purchasing these chemicals are thus a very important step for gardeners and lawn keepers since there are many factors that should be considered for personal and lawn safety.

  • Considerable efforts must give to first map out a concise plan for the lawn or garden, your mode of application, the problem at hand, and necessary measures to take.
  • There exist various types of products that serve as weed killers and getting one that is safe and of good quality can sometimes be challenging.
  • There are selective and non-selective classes of the weed killer and the mode of application of this agent will determine which is suitable
  • Since the selective type due to its selectivity may pose no threat to some adaptive weed but the non-selective weed killer kills every plant it comes in contact with.
  • So, for a newly starting lawn where no valuable or not much valuable grass is present, the non-selective would be suitable.
  • But in a standard and established lawn, using a non-selective weed killer is dangerous and can ruin years of hard work.
  • Some weed killers also affect land productivity and should be avoided if the aim of the removal is to use the land for further planting or crop production.

Features of a Weed Killer

The compounds in a weed killer optimized to incapacitate weed by restricting their growth. One variant has compounds selectively geared towards only killing weeds and plants having no agricultural or economic value whereas the other variant kills all plants.

Just consider below features while choosing a weed killer:

Chemicals and Reagents:

  • Weed killers made from various chemicals or reagents distinguishing their various abilities and potency.
  • The commonly used 2, 4-D a selective chemical compound used against garden or lawn weed and provide optimum protection against weed growth.
  • Chemicals used include glyphosate, atrazine, etc.

Plant Hormones:

  • Some killers contain synthetic plant growth hormones like auxins that are efficient in controlling plant growth and germination.
  • Naturally, plants contain growth hormones which they use in controlling their growth
  • These hormones when synthesized by man manipulated to work against some other plants and thus providing safety against weeds.

Types of Weed Killers

Selective weed killers targeted to affect only the growth of weed while the valuable plants left unbothered but the non- selective type eliminates all plant it comes in contact with.

There are three types of weed killers based on the timing of the application & these are:

1. Pre-plant Weed Killers:

  • These types of herbicides applied to the farm or garden before the planting of crops or grass.
  • They inhibit weed growth before they emerge from the soil, but once growth has occurred another type of killer called pre-emergence herbicides is used.

2. Pre-emergence Weed Killers:

  • Pre-emergence weed killers used once the seed or grass planted
  • And the seed is yet to germinate, thus having the advantage of neutralizing the weed before their seedling emerges from the soil.
  • Examples of these killers include Dithiopyrand Pendimethalin.
  • However, weeds that emerged from the soil before killer applied not affected by its activity thus bringing us to a new type of weed killer, the post-emergence weed killers.

3. Post-emergence Weed Killers

  • This set of killers used effectively against weeds have emerged successfully out of the soil surface.
  • These killers, not applied when rain is imminent as their activity neutralized or reduced by rain activity, an example of this type is the 2, 4-D.

Finally, another important classification given to weed killers is either they are selective or non-selective.

How Does a Weed Killer Works?

From hindering DNA synthesis which required for growth in a plant to introducing pathway inhibitors into some plant, a weed killer operates in various mechanisms.

Weed killers applied in two methods – either foliar application or through soil application. This set of methods determines the volatility and photolysis processes that occur in the plants to hinder and suspend growth.

Weed killers are inhibitors of weed growths and work by the following mechanisms:

Inhibition:

  • Some sets of inhibitors designed and synthesized to affect the cell membrane production by altering the process of lipid synthesis in the meristems of these plants
  • Thereby controlling the growth of these unwanted plants.
  • In ALS inhibitors, for example, inhibition of the ALS is a mechanism of weed killer actions as this intermediate is responsible for amino acid synthesis in plants.
  • Weed killers containing these inhibitors are safe for animals since this pathway or reaction only occurs in plants.

Use of Synthetic Plant Hormones:

  • Plant hormones like auxins, gibberellic acid are useful as the plant’s regulator to control and manage its growth.
  • This set of hormones, when synthesized, manipulated systematically to hinder weed growth.
