Control of small leaved Oxalis - Logran gave reasonable control. Post seeding treatments using Isoproturon gave very poor control.
Control of Oxalis purpurea (Four O'clock) - Logran either as a single application or a mixture with Isoproturon gave best control.
Control of clover - Isoproturon 4 L (post), Ally and Logran (40 g) gave 100% control.
Control of erodium - Logran gave very poor control.
Control of grasses - Isoproturon 2 & 4 Li/ha post emergent gave the best control of grasses.
Control of Four O'clock in cereals - Crop yield - Treatments using single doses of Isoproturon or mixture with Isoproturon gave the highest yields.
