This present work was carried out on the irrigated perimeter of Birni N’konni in the Tahoua region. The objective was to contribute to a better knowledge of the parasitic plant called "dodder", in order to suggest possible solutions. To do this, a survey sheet was administered to the 150 market gardeners in the Konni irrigated perimeter. The choice of each producer is random. The data collected was analyzed after cleaning. At the end of the analyzes, the results found showed that the producers are confronted, in their plots, with attacks of various parasitic plants including the dodder. These parasitic plants cause farmers to use pesticides, especially herbicides, which are not registered according to the data analysis. Analysis of the data collected also showed that most producers (90%) are familiar with dodder and its mode of parasitism. They say they are aware of the impact of parasitism on crops including tomatoes, onions and peppers. Dodder coverage rates on crops vary from 5 to 25% and the highest loss rates recorded are of the order of 18% for onion and 12% for tomato, 10% for potato. and 5% for watermelon. These results are a good indicator for technical services and researchers from a perspective of finding solutions against dodder.
