The present invention relates to a new insecticide for the protection of plants.

Chemicals such as fertilizers, antibiotics, hormones, pesticides and herbicides have been used in modern agriculture to treat plants, but it has been found that the action of these products is not sustainable and often caused unintended harmful consequences.

These chemicals generally have an alkaline reaction and, contrary to the intended purpose, they facilitate the development of diseases instead of fighting them.

One of the objects of the invention is to allow the production of an insecticidal composition based on natural plant essences therefore not containing any toxic product and capable of rapidly destroying not only the various insects harmful to plants and vegetable crops but also the eggs of these insects.

Indeed, natural essences have the property of osmosis ”, that is to say that they can penetrate through the walls of insects, constituted by chitin which is permeable to water - and without determining any apparent lesion, reach the nervous system, which they block, hence rapid death.

Likewise, there is penetration into the eggs, therefore development is suspended.

Another object of the invention is to allow the production of an insecticidal composition which can be spread over the ground and whose acidity power is opposed to the development of the spore.

We know that the notion pH indicates the state of acidity or alkalinity. However, bacteriology teaches that the saprophytic microbes essential to the life of the soil develop in an acid medium (pH: 5> 5 - 6.5) while the pathogenic microbes develop in a clearly alkaline medium. The natural essences of plants with a very acidic power (pH: 3 »5 - are therefore powerful antiseptics.

This insecticide composition for the protection of plants contains pyrethrum essences, thyme essences and Ceylon cinnamon essences.

Since pyrethrum is an antiseptic that is not very toxic to humans and animals and that it has remarkable properties with regard to a very large number of insects, that thyme is also an antiseptic, having a insecticidal power by its constituents and that Ceylon cinnamon also has an antiseptic and stimulating power, we see that the composition of the invention which contains the essences of these three plants, has an insecticidal power capable of effecting effective protection of plants treated with this composition.

This insecticide composition based on natural plant essences is used in the following manner:

A first treatment is carried out consisting in spraying the insecticide composition at 1 / 200th (one liter of composition for 199 liters of water) on the plants around the beginning of November immediately after the leaves have fallen in order to ensure destruction. insects and their eggs.

An insecticidal composition is then sprayed onto the ground in order to ensure the destruction of the fungal spores (downy mildew, monilia, scab) which have fallen on the ground and are liable to spoil there until spring, c '' that is to say when the conditions are most favorable (air, heat, light, humidity, alkalinity of the soil) to promote the development of diseases likely to affect plants.

Finally, a third treatment is carried out which consists in spraying the insecticidal composition at the time of the bud bursting, because it is the time of the laying of the insects which have been able to resist the previous treatments, this in order to avoid penetration. of the larva, after its hatching, in the bud. The particular smell of the insecticidal composition has, moreover, the advantage of causing the insects to move away.

It is quite obvious that modifications can be made to the modes of implementation described, in the field of technical equivalences, without departing from the scope of the invention.
