Situation and Environmental Impacts of Phytosanitary Treatments for Greenhouse Vegetable Crops in the Region of Biskra (ALGERIA)

Greenhouse vegetable crops in Zyban region have grown significantly in recent years, and the results still far away from expectations considering the resources put in place. This low technical and economic performance is mainly due to the combination of several obstacles, these constraints are mainly technical. The phytosanitary situation is one of the major technical constraints for almost all farmers who practice greenhouse production system in the region of Biskra because it is very far from the standards recommended by plant protection institutions, this situation is encouraged through a particular microclimate, favorable to the pests and diseases development. These cause both quality and quantity losses in production. So, through this work, we tried to use field surveys to demonstrate the phytosanitary status of farms in the study area, the causes of this situation, and the effectiveness level of different control means used by the farmers.
