Bulletin 3967 - Cyanogenetic Plants Of Western Australia, T E H Aplin

Bulletins - 3000 - 3999

This article deals with those native, naturalized and cultivated plants, which by virtue of contained cyanogenetic glycosides, are known to be poisonous or potentially poisonous to livestock in Western Australia.

Cyanogenetic glycosides are chemical compounds which contain a cyanogen (cyanide) radical combined with a sugar molecule. The sugar moiety may differ in glycosides obtained from different plants, and as a consequence glycosides from different plants, containing different sugar moieties, may be given different names.

When a cyanogenetic glycoside is broken down by enzyme action, through injury to the plant or by microbial action in the digestive system of the animal, …

The Effect Of The Herbicide Glyphosate On The Growth Of Selenastrum Capricornutum, Judith Susan Eisen

Undergraduate Honors Capstone Projects

The herbicide glyphosate (MON-0139), an isopropylamine salt of N- (phosphonemethyl)glycine, was tested to determine its effects on the growth of the fresh water green alga Selenastrum capricornutum. Experiments were carried out to determine algicidal, algistatic, and inhibitory concentrations of the compound.

Concentrations from 5 ppm to 1000 ppm were inhibitory to the growth of the alga, but the effects were algistatic, rather than algicidal. At concentrations from 0.1 ppm to 1.0 ppm the growth of the alga was stimulated by the presence of the herbicide, while at concentrations from 0.001 ppm to 0.05 ppm the effects of the herbicide were …

Effect On Bees Of Insecticides Used On Rape, A C. Kessell

Journal of the Department of Agriculture, Western Australia, Series 4

Rapeseed could provide beekeepers in Western Australia with a valuable new honey crop—hut insecticidal spraying of rape at flowering time is a potentially serious threat to most commercial beekeepers.

There are indications that insect pollination may improve rapeseed yields, so both growers and beekeepers could gain from a co-operative approach to the problem. Spraying after sundown and preventing spray drift to nearby apiaries should avoid most losses.

Poison Sedge Can Kill Stock, M E. Nairn, T. E. H. Aplin, D. S. Petterson, A. J. Brighton

Journal of the Department of Agriculture, Western Australia, Series 4

POISON SEDGE was first suspected of being toxic to livestock in Western Australia nearly 80 years ago.

Sudden deaths of sheep grazing areas on which poison sedge grew have been reported from many regions from Geraldton to Scott River.

This article reports a case of poisoning in the field, and the experimental reproduction of poison sedge toxicity in pen-fed sheep.

Poison Plants Of Western Australia : The Toxic Species Of The Genera Gastrolobium And Oxylobium : Prickly Poison And Bullock Poison, T E H Aplin

Journal of the Department of Agriculture, Western Australia, Series 4

PRICKLY POISON is one of the most widely distributed and one of the most variable of species of the genus Gastrolobium.

Is Your Farm A Haven For Grain Pests, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

Overseas markets insist that the grain they buy must be in sound condition and free of insect pests.

Keep your farm free of stored grain pests and you will help to protect our export markets and reduce the cost of treatment that you and your neighbours will bear.

Toxic Annuals In Horticulture, Robert Dunlop Royce

Journal of the Department of Agriculture, Western Australia, Series 4

THE number of poisonous shrubs and trees that are grown in gardens is very great, and several of these species have been discussed in detail.

It is probable that few people realise just how many of the commonest garden plants are in some way or under some circumstances, likely to contain a toxic principle.

Furthermore, this is not confined to the longer lived plants, but it applies equally to the annual plants, both summer growing and winter growing.

Zamia Palm Poisoning, F C. Wilkinson

Journal of the Department of Agriculture, Western Australia, Series 4

THE Zamia palm (Macrozamia Reidlei) is a common plant in the jarrah and karri forest country and on the coastal plains and is one of the earliest recorded Australian poison plants.

Control Of The Red-Legged Earth Mite And Lucerne Flea : Treatment Of Seed With Systemic Insecticides, M M H Wallace

Journal of the Department of Agriculture, Western Australia, Series 4

THE red-legged earth mite, Halotydeus destructor (Tuck.), and the lucerne flea, Sminthurus viridis (L.), are at present controlled effectively, cheaply and safely by a combined DDT/malathion spray (Jenkins, 1956, 1957) and this continues to be the general recommendation for farmers.

However, this combination has some disadvantages. The DDT in the spray ensures some residual control of the earth mite but has the unfortunate property of toxicity to the bdellid mites which are useful predators of the lucerne flea.

The malathion in the spray assists the DDT to control the earth mite and provides a good, quick kill of the lucerne …

Bulletin No 69 - The Poison Plants Of Western Australia, D. A. Herbert

Bulletins 1 - 2999

Up to the present no publication dealing with the whole of the known i)01S0fl plaits of Western Australia has been written. This Bulletin contains the collected accounts of various authors and correspondents which have been published at different times and contains a large amount of original information gathered both from field experience and from laboratory experiments. The work is not complete. A number of plants from distant districts have not been obtainable or obtainable only in amounts insufficient for exhaustive tests. These plants are comparatively few, however, and in Section 13 of this publication those which are suspected, but against …

Bulletin No 32 - Noxious Weeds And Poison Plants, Department Of Agriculture, Western Australia

Bulletins 1 - 2999

Many settlers, new to this State, find some difficulty in distinguishing those vegetable pests which are classed as noxious weeds, the eradication of which is made compulsory under the Noxious Weeds Act of 1904.

In order to facilitate the ready recognition of the plants which are the least familiar, the Department of Agriculture has prepared this Bulletin, giving illustrations of the several varieties which have been gazetted as noxious. these are: - Stinkwort, Bathurst Burr, Noogoorn Burr, Nut Bramble, Spanish Radish, Prickly Pear, Apple of Sodom, sweet Briar, Wild Bramble, Star Thistle (purple), Double Gee and Water hyacinth.
