Definition of herbicide - What it is, Meaning and Concept

A herbicide is a chemical that allows to destroy unwanted herbs .It is a pesticide whose action usually concentrates on plant hormones to prevent specimens from growing.

There are different kinds of herbicides.Some should be applied on the plants that you want to eliminate, while others they are thrown on the ground to prevent the birth of the weeds.The pesticides of direct application on the plant are degraded in the short term; those that are applied on the ground last longer.

Herbicides can also be divided between selective and non-selective. selective herbicides affect a specific type of plant, eliminating the unwanted ones without undermining the rest of the crops.The non-selective herbicides , on the other hand, destroy a wide variety of plants.That is why they are often used on roads or in areas industrial.

It is important to note that herbicides can cause serious damage to the environment, animals and people .On the one hand, their toxicity makes them substances that must be administered responsibly.On the other hand, by eliminating certain plants, sometimes the birds are left without a source of food or shelter.The herbicides can also alter the fertility of the soil and, therefore, undermine productivity farm.

One of the most controversial herbicides is glyphosate .Defined as "probably carcinogenic to humans" by the World Health Organization ( WHO ), according to Greenpeace, this chemical contaminates water and soil, reduces biodiversity and harms pollinators.

Given the disorders that herbicides can cause in the environment and the threat it poses to so many species of animals, many people choose to make them homemade, with reliable products, to keep in order their gardens while protecting their families.Weeds are a real problem; removing them is not a whim or answer to an aesthetic question, but a necessary task for plants to enjoy good health and develop properly.

One of the simplest options to prepare simply requires the use of boiling water .Yes, this ingredient is enough to kill the leaves and stalks of annoying herbs that grow in cracks or that they have invaded certain areas of the garden that we want to take advantage of.This method is very economical and easy to carry out, but it carries the risk of burns both in our body and in those who surround us.It goes without saying that when applying the water we must avoid Splash on the plants and flowers we are trying to protect.

There is another option relatively easy to implement, although much more dangerous than the previous one: burn the weed .This kills the grass in a way Immediate and prevent new leaves from sprouting.To avoid burning other plants, it is recommended to buy a tool manufactured specifically for weeding with fire, which allows heat to be applied directly to the weed.If the area is prone to fires we must pay special attention.

Common table salt, also known as sodium chloride , is another product we can use to combat weed action.Just dissolve a part of salt in eight hot water and a little liquid soap; Once the mixture is made, we pour it into a spray bottle.This effective herbicide has been widely used throughout history.It is important to note that salt can negatively affect the soil, so it should only be applied in areas affected by the grass.
