Isoproturon Evaluation - Timing Of Application On Efficacy And Crop Damage., R. Madin, J. Buckley

Experimental Summaries - Plant Research

The trial was effectively a tolerance trial. Best overall weed control was achieved with Glean and the higher rates of Isoproturon which in turn gave best control as a pre-plant, incorporated treatment.

Post Emergence Weed Control In Lupins., R. Madin, J. Buckley

Experimental Summaries - Plant Research

As a general assessment in can be said that Tigrex is a safe and efficient herbicide for control of radish in wheat. Brodal alone was generally unsatisfactory for radish control. While Diuron + Brodal was safe and efficient, Ally and Brodal should not be used together. Diuron + MCPA gave poorer control than one would normally expect.

Control Of Peas And Lupins In Wheat, J. R. Peirce, B. J. Rayner

Experimental Summaries - Plant Research

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.

Control Of Prickly Saltwort (Salsola Kali) In Pasture., G. Fleay, R. Ramm

Experimental Summaries - Plant Research

Trial 87LG65

Glean post-em @ 10 and 15 g/ha gave good control.

A later trial gave good control with Garlon 4800 or 2,4-D amine when sheep grazed the weed after treatment. Considerable pasture damage would be done with all chemicals during the growing season.

Manipulation Of The Soil Seed Reserves Of Bromus Diandrus And B. Rigidus By Enhancing The Breakdown In Seed Dormancy., A H. Cheam

Experimental Summaries - Plant Research

Location: South Perth Field Plots

Previous studies on the seed bank of Bromus diandrus indicated that shallow burial of newly shed seeds enhanced the breakdown in seed dormancy over the summer period. To bury the Bromus seeds one practical approach is to introduce sheep into the paddock.
This study is a repeat of the previous work but included B. rigidus, another species of Bromus, that is commonly ground growing in association with B. diandrus.
Location: South Perth Field Plots.

Experimental Summaries - Plant Research

Trial 87NO08
All treatments except Combine + Oil yielded significantly better than the control. Control of wild oats with Grasp was superior to many other treatments and this was reflected in the yield.

Trial 87N009
All treatments yielded significantly better than the control however there was no difference between herbicides, rates of use or additives. The exception being 0.75 L Hoegrass +WA which yielded significantly less than Grasp + oil.

The general tendency was for yield to decrease as the time to seeding after Spray.Seed application increased.
For trial 87NO85 the site was a 'problem', heavy textured soil where crop emergence problems following glyphosate had been experienced in previous years.
