Evaluation Of Fomesafen For Broadleaf Weed Control, In Soybeans (Glycine Max), Ricardo A. Jimenez

Masters Theses & Specialist Projects

The lack of effective broadleaf weed control represents one of the major factors having detrimental effects on growth and yield of soybeans. Broadleaf weeds are a serious threat to soybean growers in the southeastern United States. A broad range of herbicides is being used in an effort to control broadleaf weeds in soybeans, and research is still being conducted to find new herbicides that can best work for this purpose. This study involved the use of one these herbicides. It was fomesafen, 5-[2-chloro-4-trifluromethyl) phenoxy]-N-(methyl-sulfonyl)-2-nitrobenzamide, which controls a broad spectrum of broadleaf weeds in soybeans.

The experiment was conducted in the …

The "Soil Show" Final Report, B E. Bessen

Soil conservation survey collection

This project began with a requirement to produce a poster display for the Soil Conservation Districts Regional Workshops, in July 1988. A multi-dimensional display was produced at each of three workshops, accompanied by extensive publicity cover. As a result of the success of the displays, it was decided to maximise the exposure possible and tackle the Agricultural Show circuit. The Soil Show then travelled 7900 km, taking in 12 venues involving 16 days of public exposure in 10 weeks. It attracted up to 340 people per hour and won a number of awards. However, the major achievements were the significant …

Ontogeny Of The Cotyledonary Region Of Chamaesyce Maculata (Euphorbiaceae), W. John Hayden

Biology Faculty Publications

Development of the cotyledonary region in Chamaesyce maculata is described from germination of the seed through formation of the dense mat of branches which characterize this common weed. The cotyledonary node is trilacunar with split-lateral traces. Epicotyl development is limited to a pair ofleaves ("V-leaves") inserted directly above and decussate to the cotyledons. The two V-leaves are also vascularized by three traces and insertion of these traces relative to the vasculature at the immediately subjacent cotyledonary node is asymmetrical; four of the six V-leaf traces arise on one side of the intercotyledonary plane and two arise on the opposite side. …

Seed Production And Hard Seededness Of Trifolium Subterraneum Subsp Brachycalycinum, Michael D A Bolland

Technical Bulletins

Ungrazed swards of some subsp. brachycalycinum strains produced reasonable seed yields compared with subsp. subterraneum on the sandplain soils and annual Medicago species on the alkaline mallee soils. However, in swards which were grazed by sheep up to the start of flowering, subsp. brachycalycinum produced disappointing seed yields compared with subsp. subterraneum and annual Medicago species. On a sandy soil, prevention of burr burial compared with covering developing burrs with sand drastically reduce ation an inhibiting light factor operates to drastically reduce seed production.

The project aims to develop, by breeding and selection, better adapted and more productive low-oestrogen cultivars of subterranean clover for a range of environments in southern Australia. The programme is a collaborative one with the University of Western Australia and consists of two phases (i) early generation selection, which involves selecting varieties satisfying primary selection criteria; and (ii) field evaluation of advanced lines, which is conducted by the Departments of Agriculture in each State and co-ordinated by the Plant Breeder. The first phase is conducted …

Lupin Variety Tolerance To Herbicides, D Bowran, R Watson

Experimental Summaries - Plant Research

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.

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.

This site had a major problem with soil acidity and only triticale and oats grew satisfactorily. Barley was strongly influenced by the acidity and many …

Objective: To measure reproductive output in relation to times of emergence and herbicide application.

Trial No. 88WH10

Growth of doublegee under summer irrigation.

Objectives: A major impediment to achieving biological control of any annual weed in the wheat belt is that the bicontrol agent must have a means of aestivation. Since the only insect to have been introduced to Australia for a the control of doublegee does not aestivate, it was thought that populations could be able to oversummer in irrigated doublegee standards. The aim of this study was to assess the …
