Trial 88EC31
This site received a basal treatment of 1.5 L of simazine/ha prior to seeding. Due to a heavy stubble load lupin seed was dropped onto the surface and lightly incorporated.
High rates of Simazine were better tolerated by Gungurru 75A/260 and CE2/435. The highest rate of Brodal reduced yields in all varieties except Gungurru.
Trial 88EB27
This site was severely infested with aphids and bean mosaic virus such that the varieties Illyarrie and Danja had up to 60% plant death by anthesis. Other varieties were affected but to a lesser extent.

In 1988 a research programme was initiated to help define the relationship between soil and plant contamination. Two main experiments were established 1) Pasture contamination in annual and perennial grazed swards. 2) Plant species contamination in a wider range of pasture and crops.

Experimental Summaries - Plant Research
Trial 88EC17
Location: East Chapman Research Station.
The plots were hand sown at 2 g/m2 of inoculated and lime pelleted seed. The medics were inoculated with WSM540 which may have been ineffective on some of the M. littoralis and M. tornata varieties. The time taken to form ripe pods was monitored to gain some extra measure of maturity besides flowering time for comparing wide ranges of species. The ripening time involved was very similar over all the varieties, averaging out to 44 days after the flower opens. What appears to be a more important factor when considering maturity is the …

Trial 88EC18
Location: East Chapman Research Station.
Half the trial site was cultivated to 30cm at the break of the season and the whole site was normally cultivated. Weeds were then sprayed with Roundup at 1 1/ha prior to seeding with an eight run cone seeder. The plots were kept weed free during the year by hand weeding. The root distribution was calculated from soil cores taken in 20 cm increments on 20 August. Aphid cortrol consisted of spraying every two weeks with Pirimor at 140 g/ha between July and October. Lorsban at 150 ml/ha was used for the last …

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.

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.

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.

Trial effect of timing of Roundup CT and Spray.Seed application and cultivation on crop establishment and growth.
87WH53, 87NO85
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.
