Herbicide registration in durum wheat and barley trials

Herbicide trials are conducted on a plot sown with durum wheat and a plot sown with barley and both divided into plots according to the randomized complete block experimentation protocol. The aim of these trials is the homologation or not of these herbicides or some of them with reference herbicides known and available on the Tunisian market. Two broadleaf control products H04 and H05 are compared with the reference product Granstar. This first trial is carried out on the durum wheat crop variety RAZZAK. Three other broadleaf weed control products H08 H10 and H11 were compared to the reference product Traxos on the same crop as the first trial. A single multipurpose product H07 is tested on the barley crop and is compared to the reference product Amilcar OD.
