Abstract

The national production of cereals confronted with weeds causes losses estimated at 30% to 50% of yield at the national level. At the same time, a good choice of herbicide and the identification of the best dose is essential to eliminate weeds and have a good yield of durum wheat.

This work concerns the identification of the best dose of Floramix used in the cultivation of durum wheat as well as the identification of the biological families of weeds competing with durum wheat in order to control them effectively. The test was conducted in the open field following a completely random device, three doses of herbicide were chosen, Dose1 (16 mg/ M2 (square meter)), Dose2 (32 mg/ M2 (square meter)), Dose 3 (64 mg/ M2 (square meter)) and control (Without Treatment).

The identification of the best dose makes it possible to avoid the unnecessary use of higher doses since the latter are very polluting, and the census of weeds makes it possible to move towards the more specialized use of herbicides to better control them the census of the most dominant botanical families is that of the dicots, the primulaceae followed by the fabaceae, on the other hand the poaceae (monocotyledons) come in 3rd position. The dicots appeared at the same time as the beginning of the culture, on the other hand the monocots appeared late.

The study conducted on the action of the herbicide Floramix on durum wheat (Triticum durum desf. cv vitron). Allowed us to conclude that the high dose (64 mg/m2) has a negative impact on the yield parameters despite the elimination of all the weeds, with a low yield close to the Control Block with 24.56 Quintals / Hectar). While the recommended dose (32 mg/m2) records the best yield of 45.45 Quintals/Hectar, dose 1 comes second at (28.69 Quintals/Hectar), the use of an against dicots herbicide is recommended in order to eliminate the most competitive weeds.
