Our job is to study the main phytosanitary problems in the old oasis of El Ménéa. We conducted surveys of
a sample of farmers in the study area. We used a survey guide to characterize farms, identify phytosanitary
problems, damage and control methods. The results indicate the presence of different types of pests such as
citrus leafminer, citrus fruit, aphid, white scale, date moth and mole cricket. Only one cryptogamy disease
has been encountered, this is blue and green mold. In contrast, physiological diseases are more numerous
and include iron deficiency, leaf rolling and yellowing, and fruit drop. On the other hand, we have noticed
the frequent presence of weeds such as Quackgrass and Diss. For the means of control practiced against
these phytosanitary problems, the majority of the farmers use rather simple means of struggle. There is no
effective struggle by farmers against these enemies.
