Enquête sur les problèmes phytosanitaires des grandes cultures dans la région d’El Ménéa

Abstract

This work focuses on the study of phytosanitary problems related to field crops in the region of El Ménéa. The objective of our work is to identify the problems that harm field crops, how farmers deal with them and the control methods applied. We conducted surveys on a sample of representative farms in the region and tried to identify existing phytosanitary problems, including pests, diseases and weeds. The results of our investigations indicate the presence of aphids (Rhopalosiphum padi), plant bugs (Aelia germari) and sparrows (Passer domesticus x P.hispaniolensis), as pests linked to field crops. Regarding diseases, our surveys show that farmers suffer from fusarium (Fusarium spp) and septoria (Mycosphaerella graminicola). Finally, for weeds, we recorded the presence of bromegrass (Bromus rigidus), ryegrass (Lolium miltiforum lam) and wild oats (Avena sterilis). Most farmers use the preventive method and the chemical method to combat these problems.
