The use of pesticides in agriculture does modernize us, as it dates back to antiquity. Sulfur, arsenic and also tobacco were the first to be used in this fight against diseases and pests.

Since, pesticides have evolved from natural to chemical products but have especially experienced a very strong development, the proof in the numbers: from 1945 to 1985, the consumption of pesticides doubled every ten years.

The poor application of pesticides, their storage without precaution and the discharge of residues are responsible for significant contamination.


A large portion of the pesticides is dispersed in the air. Once sprayed on the plant, the air takes them and deposits them on other plants. Sometimes even rains drag them into aquatic environments. All the ecosystems are, therefore, touched and placed in danger.

The role of technicians is therefore of informing the producers of our intervention villages, by showing them that there are effective alternatives and explaining to them how to use them if the situation forces it.


  1. The preparation of the land and cultures


For Dahari, it is above all necessary to explain how to feed the soil, adequately water, adequately aerate the cultures to prevent having attacks. As with humans, a well-fed, well-raised plant is more resistant to diseases and external attacks.

This is, therefore, the daily work of our technicians: to learn the good agricultural practices of the producers of the island and most accurately recommend them, by taking into account the environmental component and the economic component (their returns.)


  1. The nutritional complementarity and the analysis of one’s environment: the plants protect the plants


Knowing how to analyze one’s environment and understand it is essential. The ecological equilibrium must be maintained to have a healthy productive context.

It is necessary to have a strategy for knowing how and when to plant, how to organize its cultures because one does not just do it any old how. Planning one’s production is therefore a primordial step and the association/rotation of cultures is part of it. In CRDR for example, Inzoi—Dahari technician—combined the onion with the carrot and the lettuce, a good way to naturally fight the parasites.

There are many other techniques allowing, therefore, to minimize the use of chemical products. To adequately combine plants, there are some principles to know:

–  The Apiaceae reciprocally protect each other.

– The Leguminosae enrich the soil in nitrogen. Combining and/or integrating them in rotation with fertility demanding plants such as the tomato or corn is recommended.

Analyzing one’s environment is also knowing what the useful insects are and understanding that the overused pesticides can kill them and thus unbalance the ecosystem. It is also understanding that each production has its specificities and that the treatment has, therefore, to be adapted.

  1. The treatment of the attacks with natural insecticides

Did you know? A chili-soap mixture is a simple and natural solution to protect the cultures.

  1. The sensible use of pesticides

One can neither prevent nor be present daily behind each farmer; one must therefore inform and explain what the risks are, particularly why and how to avoid them.

The dosage (apply the correct dose by using a pulverizer and not a plastic bottle), the protection (gloves, long sleeves, hygiene0, the choice of products (which product for which insect(s)/or buy?), the proper dosage as a function of the degree of the attack and the storage of the pesticides (at a height and well-labelled) are the themes that Dahari sets for awareness.
