Why use natural products to fumigate plants

Today we can find many synthetic products intended for the elimination of plant pests. These products are very effective. However, they are also dangerous, often both for the plant, for the people and animals that live in the house and for the environment in general. Keep in mind that most synthetic products are so effective because contain toxic products. Its function is to eliminate a plague and, for this, it is necessary that they act as a poison for said plague.

However, this also causes them to have secondary effects that, although they may not be seen a priori, are there and significantly affect the ecosystem. On the one hand, it must be taken into account that these are synthetic and toxic products that, although they are formulated for plants, this does not mean that they are harmless to them and their environment. In general, used correctly, that is, following the manufacturer’s instructions, it should not pose a risk to the plant. However, high use could lead to damage or even death of the plant. For this reason, they pose more risks than natural products which, although they are not always harmless, do not have the same level of risk, that is to say that natural products to fumigate plants are safer.

Secondly, these are toxic products and, therefore, they are identified with icons or symbols that warn that they must be “kept out of the reach of children”. Naturally, an adult person is not going to consume these types of products by accident. However, in homes where there are children and pets, it is a real risk that must be considered. On the contrary, the use of natural products eliminates this unnecessary risk.

Finally, it must also be considered that the use of synthetic pesticide products entails damage to the pest and to other types of organisms that, in many cases, are positive for the plant. Synthetic products, precisely due to their power, eliminate practically any organism that comes into contact with the plant. This includes, for example, pollinating insects such as bees, which are beneficial and necessary for many plant species. This is the case of neonicotinoids, here we tell you what neonicotinoids are and their effect on bees and the environment.

In addition, these synthetic products take a long time to break down, so they end up in other ecosystems washed away, where their effects continue to be disastrous for many forms of life.

What types of pests can attack plants

When using a natural product to fumigate a plantwhether it is fumigating in the garden, the orchard or inside the house, the first thing to be clear about is what type of pest we want to eliminate from the plants: bacteria, viruses, fungi or insects.

In this sense, a plant disease caused by a bacterium will not be the same as one caused by a fungus, a virus or an insect, they will not be the same problems and symptoms and the same treatment will be followed. Likewise, it will also be necessary to take into account the place of the plant where it is located, since a pest located in the leaves will not be the same as in the roots, for example.
