THE RESULTS OF TESTING HERBICIDES IN POTATOES

Two trials were carried out during 1972. and 1974. in which more different herbicides were applied for the weed control in potatoes. Metribuzin, cyanazine, metoxuron, linuron, metobromuton, cyanazine + linuron and terbutryne + GS-13259 have been tested in Velika Gorica during 1972- Metrilbuzin, prometryne chlorbromuron, metoxuron, atrazin + prometryne, alachlor + linuron, linuron + monolinuron and prometryn + simazin were included in trial during 1974. The applications were made 7 (V. Gorica) and 19 (K. Kraljevac) days after planting. Much better weed control has been obtained when herbicides were applied 19 than 7 days after planting. Metribuzin, metobromuron and a mixture cyannazin + linuron gave the best weed control in 1972. Metribuzin again and the mixtures linuron + monolinuron and atrazin + prometryne gave very good results in 1974
