NEEM.FR is a website for nature enthusiasts actively supporting the development of Neem. Our goal is to facilitate information for the public and professionals to draw attention to the many possible applications of Neem.


The Neem Tree


To protect themselves from insect attacks, many plants produce chemicals with various properties: toxic, growth-regulating for insects, or even anti-appetizing (appetizing = nourishing), or phagodissuasive. The Neem tree produces over a hundred chemical substances through its fruits, leaves, flowers, and bark, among which one of them (azadirachtin) is one of the most effective bio-insecticides.

Neem worldwide

The International Neem Network was established in 1994. It focuses on the exploration and evaluation of the genetic diversity of Neem. National institutes from 23 countries in Asia, Africa, Latin America, and Europe are involved in the Network’s activities, with overall coordination provided by the FAO Forestry Department (Food and Agriculture Organization of the United Nations). Technical support, including the provision of engineers and laboratories, is provided by the Danida Forest Seed Centre (DFSC), now integrated into Forest and Landscape Denmark (an independent Danish center at the University of Copenhagen (UC) for forests, landscapes, and planning).


About Neem

In Brazil, all fruit and vegetable producers, as well as agricultural product distributors, are familiar with Neem, a commonly used product since 2001, especially for animals and agriculture.

The Organic Alternative

Azadirachtin-A, naturally present in Neem, effectively fights against a large number of pests. Over the last 25 years, entomologists have isolated more than 400 different species…

Did You Know ?

At maturity, the Neem tree can produce up to 50kg of fruit, which is equivalent to 30kg of seeds; these seeds are the main source of insecticidal compounds, including azadirachtin. However, the quantity of azadirachtin in the seeds varies considerably depending on climatic conditions, soil conditions, and the tree’s genotype (Ermel 1986; Singh 1986).
