Control of peas and lupins in oats

Trial 87A30 All lupin treatments satisfactory. Treaments 4, 8 and 9, ie Dicamba 500 ml and both treatments with diuron + 2,4-D amine would not control peas sufficiently to prevent rejection of line of oats. Peas are more difficult to control

Control of Saffron thistle in pasture using goats.

Trial 85TS27 / 87TS27 Saffron thistle seedling densities remained relatively constant during the first two years of the trial, irrespective of the grazing treatments\u27 effectiveness. However on the grazing treatments where goats were preventing seed formation, once the bulk of dormant seeds had been depleted, seedling density started to decline

Control of soursob (Oxalis pres-caprae) in cereals

Trial 87NO107 Plant counts for soursob and Four O\u27clock will be more accurate when counts taken after the break of 1988 season to determine the bulb production from last season. Ally gave good control of doublegee. Isoproturon or mixtures with Isoproturon also gave good doublegee control. Logran & Glean were weak on doublegee

Control of peas and lupins in wheat

Trial 87A29 Lupins were easier to kill than peas. Glean applied pre-sowing gave very poor control of both peas and lupins. The treatment using higher rates of 2,4-D amine in diuron mix also caused lower yields. The Tordon 242 treatment appeared to cause some yield depression

Saffrom thistle, seed set control

Trial 87ME119 - Saffron thistle, seed set control. Trial 87TS38 - Saffron thistle control (seed set) Trial 87JE42 - Seed set control in Saffron thistle. All treatments had some measure of reducing seed production. Best control was obtained by applying chemicals just at or prior to flowering

Control of four o\u27clock (Oxalis purpurea) in cereals.

Trial 87KA85 Because of the late dry season, yields were below expected. Under these conditions there were high visual crop damages recorded early after the treatments applied

Chemical control of four o\u27clock (Oxalis purpurea) and narrow leaf oxalis (Oxalis glabra).

Trial 97NO95 Control of small leaved Oxalis - Logran gave reasonable control. Post seeding treatments using Isoproturon gave very poor control. Control of Oxalis purpurea (Four O\u27clock) - 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\u27clock in cereals - Crop yield - Treatments using single doses of Isoproturon or mixture with Isoproturon gave the highest yields
