neemland ecosystem sarl
The company was formed in august 2009 and aims at
promoting an agroecologic model based on the development
and the use of neem products in the agricultural sector for a
better protection of the cultivation.
To achieve this goal, we work closely with rural communities
in a participative process that involves a gender approach
and generates incomes for both parties.
Neemland Ecosystem’s corporate values are: Quality,
Respect of the Environment, Cooperation for Development,
Flexibility, Service, Integrity and Responsibility.
We bring efficient, practical and natural solutions for a
productive agriculture environmentally friendly.
Neem seeds supply chain
Because of the seasonally harvesting of neem seeds , a
decentralised recolecting network is created at village level.
Neem seeds recollection and selling generate income in
rural communities—perhaps a small, but nonetheless
valuable, benefit in these days of mass flight to the
cities in a desperate search for jobs. It can be a useful
export good as well; nowadays tons of neem seed are
often sold and shipped from African ports (Dakar, for
example) at more than twice the price of peanuts. On
top of all that, neem by-products (the seedcake and
leaves, in particular) actually may improve the local
soils and help foster sustainable crop production.
We have four main products:
• Neemland Oil (natural cold pressed neem oil )
• Neemland Rakkal (neem cakes)
• Neemland Powder (neem leaf powder)
• Neemland cosmetic soap
They are respectively used as:
• Insecticide, fungicide insect repellent
• Plowed into the soil it protects plants from nematodes and acts
as a fertilizer.
• Repels insects from stored cereals such as maize, sorgho,
• Soap for body care and laundry.
The use of neem by-products for pest control is significant
because most developing countries are in the tropics, where
year-round warmth often allows pest populations to build to
The problems attendant on using synthetic pesticides,
therefore, are particularly severe in the Third World. For
instance, the World Health Organization attributes 20,000
deaths and more than a million illnesses each year to pesticides
mishandled or used to excess.
By and large the need of neem product in Third World
countries is widely justified by nutritional, economic, and
The local agricultural sector is our short term market.

Neem is a member of the mahogany family, Meliaceae.
It is today known by the botanic name Azadirachta
indica A. Juss.
Neem trees are attractive broad-leaved evergreens
that can grow up to 30 m tall and 2.5 m in girth. Their
spreading branches form rounded crowns as much as
20 m across. They remain in leaf except during
extreme drought, when the leaves may fall off.
The short, usually straight trunk has a moderately
thick, strongly furrowed bark. The roots penetrate the
soil deeply, at least where the site permits, and,
particularly when injured, they produce suckers.
The fruit is a smooth, ellipsoidal drupe, up to
almost 2 cm long. When ripe, it is yellow or
greenish yellow and comprises a sweet pulp
enclosing a seed. The seed is composed of a shell
and a kernel (sometimes two or three kernels),
each about half of the seed's weight. It is the
kernel that is used most in pest control. (The
leaves also contain pesticidal ingredients, but as a
rule they are much less effective than those of the
A neem tree normally begins bearing fruit after 3-
5 years, becomes fully productive in 10 years, and
from then on can produce up to 50 kg of fruits
annually. It may live for more than two centuries.
What's in a Neem
Neem protects itself from the multitude of pests with a
multitude of pesticidal ingredients. Its main chemical
broadside is a mixture of 3 or 4 related compounds, and it
backs these up with 20 or so others that are minor but
nonetheless active in one way or another. In the main,
these compounds belong to a general class of natural
products called "triterpenes"; more specifically,
"limonoids.”At least nine of them have demonstrated an
ability to block insect growth, affecting a range of species
that includes some of the most deadly pests of agriculture
and human health. Azadirachtin, salannin, meliantriol,
and nimbin are the best known and, seem to be the most
Methods of application
Neem extracts can be applied in many ways, including
some of the most sophisticated. For example, they may be
employed as sprays, powders, drenches, or diluents in
irrigation water—even through trickle or subsurface-
irrigation systems. In addition, they can be applied to
plants by emulsifying the crude oil and spraying it even
with a branch of neem leaves or a sprayer. Moreover, they
can be added to baits that attract insects (a process used,
for instance, with cockroaches).
Effects on insects
Neem products work by intervening at several stages of an
insect's life. various neem extracts are known to act on various
insects in the following ways:
Disrupting or inhibiting the Poisoning larvae and adults;
development of eggs, larvae, or Deterring feeding;
pupae; Blocking the ability to "swallow"
Blocking the molting of larvae or (that is, reducing the motility of
nymphs; the gut);
Disrupting mating and sexual Sending metamorphosis awry at
communication; various stages; and
Repelling larvae and adults; Inhibiting the formation of chitin.
Deterring females from laying
Left row: untreated white cabbage,
badly damaged by diamondback
moth (and aphids).
Right row: cabbage treated with
aqueous neem-seed-kernel extract is
largely undamaged. On the
diamondback moth, neem exerts a
combination of effects: it repels, it
deters oviposition (eggs that are laid
never hatch), and it disrupts
molting. This extremely serious pest
is found worldwide and in some
locations is playing havoc with vital
crops of leafy vegetables such as
cabbage. (H. Schmutterer)
All of this is potentially of vital importance for the senegalese
and african farmers many of whom are confronted with various
agricultural pests, and a widespread lack of even basic medicine.
The neem tree is growing in all the senegalese regions and it can
grow on certain marginal lands where it will not compete with
food crops. Thus, it could bring good health and better crop
yields within the reach of farmers too poor to buy
pharmaceuticals or farm chemicals. It makes feasible the
concept of producing one's own pesticide because the active
materials can be extracted from the seeds, even at the farm or
village level. Extracting the seeds requires no special skills or
sophisticated machinery, and the resulting products can be
applied using low-technology methods.
