Tolurex is an early pre-emergent herbicide, selective for cereals. It is absorbed mainly by the roots of weeds. It is then conveyed by the raw sap to kill weeds. It is effective against herbicide-resistant ryegrasses. It also destroys the seedlings of many broadleaf weeds, its spectrum being larger in early post-emergence than in pre-emergence.
Tolurex contains 500 g/l Chlorotoluron in a Suspension Concentrate (SC) formulation
Tolurex is aplied against Avena Fatua in Barley and Wheat
