Langues : Français (fre) Catégories : Agronomie Mots-clés : Pesticide  agricultural practices  tomato  Solanum lycopersicum L.  Tipaza. Index. décimale : 630.17 Résumé : The survey conducted with 60 farms in the Tipaza region provided a comprehensive overview of agricultural practices related to pesticide use in tomato cultivation (Solanum lycopersicum L.). Technically, tomato farming is mainly practiced under greenhouse conditions (58.3%), often with intercropping (90%) on small farms (≤5 ha). Drip irrigation is the predominant method (93.3%). Regarding fertilization, a combination of chemical and organic fertilizers is used by 81.3% of the farmers. The study also highlights a strong phytosanitary pressure. The most frequently reported pests are the red spider mite (73.3%), tomato leafminer (66.7%), and aphids (40%). Among diseases, late blight (58.3%) and powdery mildew (43.3%) are the most common. To control these, farmers mainly use fungicides (35%), acaricides (30%), and insecticides (30%). However, risky practices persist: 70% of producers mix several pesticides, and 17% do not respect recommended doses. Spraying is exclusively manual, with 86.7% using motorized sprayers, exposing farmers to direct contamination, especially since only 27% consistently use personal protective equipment. Health consequences are significant: 63% of farmers report side effects related to pesticide use, including respiratory disorders (43%), skin irritations (25%), and occasional hospitalizations. Moreover, 47% of producers report environmental impacts, notably a decline in bee populations. In response to these issues, 85% of producers express a willingness to reduce pesticide use.

Inventaire des nématodes phytoparasites associés aux agrumes dans quelques vergers de la Mitidja / Yacine Fedila

Langues : Français (fre) Catégories : Agronomie Mots-clés : Inventory  Nematodes  Phytoparasite  Citrus  Mitidja. Index. décimale : 630.19 Résumé : This study was conducted to inventory phytoparasitic nematodes associated with citrus orchards in the Mitidja region. The survey covered 14 orchards located between the Blida and Algiers provinces from February 1, 2025 to May 1, 2025. A phytosanitary survey using a questionnaire collected data on cultural practices, the phytosanitary status of trees, and its relationship to yield. Nematological analysis of soil samples revealed the presence of five genera of phytoparasitic nematodes: Tylenchulus, Pratylenchus, Ditylenchus, Longidorus, and Radopholus. The Shannon diversity index (H' = 1.17) indicated moderate diversity among the identified nematode genera. However, the genus Tylenchulus was the most frequent, detected in 92% of orchards, followed by Pratylenchus (21%), while other genera were found with frequencies ranging from 7% to 14%. Migratory endoparasites dominated the parasitism types, representing 60% of cases. Symptoms consistent with nematode infestation, such as chlorosis (57.14%) and reduced fruiting and yield decline (50%), were observed at concerning levels. Furthermore, the co-occurrence of insect pests was reported in most orchards, with high rates of aphids (50%), scale insects (42.86%), and citrus leafminers (42.86%).
