Weed Control In Cereals And Pastures Including Declared Plants., J. Peirce, B. J. Rayner

Experimental Summaries - Plant Research

Trial 90C49

Grass and broad leaved weed control in direct sown crops.

Location: Chapman Valley Research Station.

The low rate of sprayseed with diuron was not as effective on the grasses. It may indicate some antagonism within the mix as the same rate of sprayseed with metribuzin did not cause any drop in grass control. The addition of 2, 4-D amine may have boosted the mixes activity on capeweed as the sprayseed metribuzin mix was not very good on capeweed.

Development And Management Of Cattle Pastures In The High Rainfall Zone., Tony Albertsen

Experimental Summaries - Plant Research

Trial 87V8

Development and management of cattle pastures in the high rainfall zone.

To compare the effect of pasture species, pasture management and grazing management on pasture quantity, quality and cattle production.

Phalaris evaluation

In 1989 ninety three lines of Phalaris agrundinacea backcross with P. aquatica, bred by Dr. R.N. Oram (CSIRO Canberra) were drilled sown into unreplicated 10m single row plots at Vasse Research Station. In addition 7 controls (with two replications) were planted. Similar trials were planted by Mr. L. Cransberg (Albany) and Dr. R.N. Oram (Bendigo).

Depth Of Placement And Rates Of Nitrogen For Lupins On The South Coast., M. Seymour

Experimental Summaries - Plant Research

Trial 90E13

Starter nitrogen for lupins, rates x depth of placement.

To determine if the application of nitrogen at seeding will enable lupins to grow vigorously at the beginning of the season, and have better growth at flowering. Deep placement is used to reduce the effects of high nitrogen fertiliser on plant establishment.

Biological Activity And Conformational Analysis Of Nikkomycins And Their Analogs, Eduardo Krainer

Dissertations, Theses, and Capstone Projects

Nikkomycins and polyoxins are peptidyl nucleoside antibiotics produced by Streptomyces species. They are potent inhibitors of chitin synthetases from pathogenic fungi, and polyoxins have been used in Japan for many years as agricultural fungicides and for insect control. Since chitin synthetase is not found in mammals and both families of antibiotics are not toxic, these inhibitors are potentially attractive for clinical use. Unfortunately these compounds seem to have only a fungistatic action, and they are not used clinically at present.

A procedure for efficiently obtaining nikkomycins X and Z of very high purity from crude antibiotic is described. These nikkomycins …
