Bulletin 4358 - Western Australian Registered Field Crop Scheme Production Rules, Mark Holland, Peter Hill

Bulletins 4000 -

The Western Australian Registered Field Crop Scheme is an industry cooperative scheme entered into voluntarily by the participants. Agriculture Western Australia, through its AGWEST Plant Laboratories business unit, administers the scheme and supervises industry agreed production and marketing guidelines.

The Registered Field Crop Scheme differs from certified seed schemes by reduced direct supervision of the production by Agriculture Western Australia.

Producers agree to abide by the following rules and are responsible for the correctness of the final product to meet the quality descriptions for each seed lot as described on the appropriate seed analysis statement and in these rules.

Tolerance Of New Cereal Varieties To Current Herbicides., D Bowran

Experimental Summaries - Plant Research

Trial 88EB26

While this site had a low population of weeds no yield increases were apparent. Few variety differeces were apparent at this site, though Hoegrass + Glean reduced yield of Crabook significantly.

Trial 88EC27

Few crop effects were experienced at this site. The major effect was due to variable fertility in replicates 3 and 4 and this resulted in the somewhat uyp and down nature for the Glean, Logran and hoegrass results.

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.
