The present study deals with the efficiency of oxadiargyl - herbicide raft 800 WG for weed control, its selectivity in seed onions for onion production and its effect on the quantity of some actively developing soil microorganisms. The herbicide was applied post planting, prior to onion and weed germination at a dose of 28 g/dka active ingredient. It has been established that oxadiargyl in dose of 28g/dka (1 dka=1000m2) is efficient for control of annual dicotyledonous and grass weeds and it is selective for onions.Oxadiargyl has no negative effect on soil biological activity.
