More information:
The fertilization of the leaves consists in spraying the fertilizer straight away on the vegetables’ foliages. The effect of this type of fertilization is very fast because the nutriments are immediately assimilated and used by the plants. The fertilization of the leaves is especially useful after moments of stress (transplantation, the wind, the hail, the cold, the dryness and the heat) or in the case of serious nutritional deficiency. It is mostly used as an extra-fertilization and settles a problem of deficiency in a short-term period. For a solution in a longer-term period, it is important to fight the reason of the imbalance. For instance, if the mineral deficiency is a result of a too acid pH, we need to mix some enriching agents into the soil. The nutritious elements contained in the fertilizer get into the leaves through tiny openings called stoma. These ones are generally more numerous on the inferior side of the leaves. We have to take it into account during the application of the fertilizer and spray underneath the leaves. The fertilizer for the leaves is better swallowed if it is applied very early in the morning or in the evening because the air is fresher and the ambient humidity is higher what favour the opening of the stomata.

Arthropods (Greek: “arthron” means “joint” and “podos” means “foot”, also called “jointed”) form a phylum of invertebrate animals. Arthropods are characterised by the possession of a segmented body with appendages on each segment. All arthropods are covered by a hard exoskeleton made of chitin. Today the phylum of arthropods is the largest; it has over a million modern species of arthropods.

An ovicid phytosanitary product is an active substance or a preparation capable of preventing the evolution of the eggs by killing the embryo. To protect the cultivations against the parasites, the knowledge of the ovicid characteristics of the phytopharmaceutic products applied and the knowledge of the date of the beginning of laying allow reasoning with the use of insecticides and mite-killers.

A larvicid phytosanitary product is an active substance or a preparation that is specifically targeted against the larval life stage of an insect. To protect the cultivations against the parasites, the knowledge of the larvicid characteristics of the phytopharmaceutic products applied and the knowledge of the date of the beginning of laying allow reasoning with the use of insecticides and mite-killers.

Allopathy: usual mode of medical treatment that fight the disease by using medicines which have an effect opposite to the pathological phenomena.

The azadirachtin extract contained in the neem’seeds was very efficient against the larva that were destroying the foliages, against 13 species of lepidopterous insects and against sawflies.

Did you know?

When the tree reaches maturity, it can produce until 50Kg of fruits what is equivalent to 30Kg of seeds. These ones constitute the main source of components with some insecticidal properties as the azadirachtin. However, the quantity of azadirachtin contained in the seeds considerably changes according to the climatic conditions, the soil conditions and the genotype of the tree (Ermel 1986 ; Singh 1986).
