Résumé:
In order to understand the situation of chemical control in crop protection in Guelma region, a
survey was conducted over the last five years, between 2019 and 2024. It involved various interveners
in the agricultural sector of the wilaya, including distributors of phytosanitary products, the Cereals
and Dried Vegetables Cooperative (CCLS), and the Agricultural Supply Service Cooperative
(CASAP), as well as users of these products, such as pilot farms and farmers. The survey focused on
four major types of crops: cereals, vegetable crops (excluding tomatoes), industrial tomatoes, and fruit
trees. The collected data revealed that different types of active substances, belonging to different
chemical groups and modes of action, are used for the treatment of various crops. However,
considerable amounts of pesticides are used each year in the wilaya, and the same active substances
have been employed every year since 2019, which may promote the development of resistance to
these products among pests and parasites.
