THE toxic species of the genera Gastrolobium and Oxylobium are a unique group of poison plants which have caused considerable economic loss to stock-raisers in Western Australia ever since the early days of settlement.

These plants are widely distributed over the agricultural areas of the south-west, and, with the opening up of large tracts of land for stock-raising, the danger is as high as it has even been.

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

THE usual method of killing poison plants is by a programme of ploughing, cropping and burning.

The burning not only destroys a proportion of the plants, but stimulates the germination of dormant seeds, which otherwise would remain in the soil in a viable condition for many years.

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.

Avoid Losses From Poison Plants, Robert Dunlop Royce

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

E VERY country in the world has its poisonous plant problems, but in Western Australia we have more than our share.

Farmers in "Poison" districts can avoid serious stock losses if they can recognise dangerous poison plants, and have a knowledge of how the concentrations of toxic substances in these plants change with the seasons.

In this article, R. D. Royce, Officer in Charge of the Botany Branch, outlines the principles involved.
