CALTROP WEED

T HE Department of Agriculture has expressed concern at the spread of the noxious weed, Caltrop. Specimens of this weed have been received from a number of localities including Kondinin, Walgoolan, Carnamah, Morowa, Pingelly and Bruce Rock, adding considerably to the previously recorded range of this plant in Western Australia.

Caltrop is a prostrate summer grow- ing annual with spreading stems which may extend for three feet or more from a strong taproot. Each leaf is divided into several pairs of leaflets and the yellow flowers are about one half inch across. The most conspicuous part of the plant, however, is the burr like fruit which separates readily into five wedge shaped segments each bearing four spines in pairs. The burr has often been compared and sometimes confused with the double-gee.

Caltrop has several undesirable features. The burrs cause mechanical injury to stock, the spines penetrating the frog of the hoof and giving rise to Painful sores. Burrs ingested with other herbage have caused injury to the walls of the stomach and intestines. The plant also possesses toxic properties, stock losses due to it having been experienced

in South Africa and also in Queensland and New South Wales.

Control measures should be designed to prevent seed formation. Plants not detected before seeds have formed should be handled carefully as the seeds scatter easily. Isolated plants should be de- stroyed by burning them in situ. For coping with large infestations, deep ploughing is inadvisable as the longevity of the seeds allows further germination when subsequent workings bring them to the surface. The objective should be to destroy the plants and induce germination in order to exhaust the seed supply present in the soil.

Chemicals have been found very useful for Caltrop control. The plants are killed by the application of oil sprays such as diesolene, kerosene or a mixture of one of these with old sump oil. This treatment also affects the germination of seeds in dry burrs. The 2,4-D or hor- mone-like chemicals also give good results but have little effect on the seeds and, therefore, must be applied at an early stage of growth in order to have maximum effect.

Farmers acquainted with the undesir- able features of Caltrop do not have to be reminded that it is a primary noxious weed before taking active measures against it.
