This process was very for two years because of drought conditions. expensive and plants were difficult to get out of This site has been improved by enlarging it to culture, better horticultural practices (giving the 0.2 ha, fencing with rabbit proof wire, fitting a jars/cultures, more light and drying them out until reticulated irrigation system, and adding over the agar starts cracking) have improved survival 1000 new plants to the site in 2003, with further rates.

Germination occurred mainly by the Department of the Environment under dead Grevillea scapigera plants where and Heritage, and also by smaller grants through there should be a large soil seedbank, and World Wildlife fund. The recent site enlargement between rows of plants amongst Cape weed and improvement was funded by the Western Arctotheca calendula. This illustrates there is Australian Government, Environment Ministers a disperal agent on site eg ants, and some Community Conservation Grant. seedlings are capable of germination and survival In the wild amongst severe competition from weeds. These seedlings are not being watered as we wish to look at natural survival rates and establish if the translocations can be self sustaining in the long term. Further recruits have been recorded this year on the same site and on another site for the first time. Herbicide trials for the control of Cape weed have been conducted to test the efficacy and crop tolerance. To date one herbicide has shown no deleterious effects, at high rates, when applied to mature plants. The same herbicide has been trialed over seed and seedlings in glasshouses as a pre and post emergent herbicide. At high Grevillea scapigera rates some damage has resulted when applied directly to seedlings. No deaths have occurred and the plants are being grown on to monitor the long term effects.

The Department of Environment and Conservation has identified 9 priority actions to help recover the Guthrie’s Grevillea in New South Wales including: – Collect seed from each population and maintain an ex situ seed collection – Monitor, survey and research the populations at Booral, Banda Banda and Carrai. – Prepare and disseminate community awareness information.

Whitefly – an unaccustomed pest of Grevillea

The location on the plant of the various also can be transmitted by whiteflies, such as stages of the whitefly follows the development the geminiviruses in tomatoes, peppers and of the plant. Eggs and early instar nymphs are cabbage, and certain clostroviruses like lettuce found on the young leaves and larger nymphs infectious yellows in lettuce and melons. Plant are usually more numerous on older leaves. disorders and virus transmission are of particular concern because they can occur even when a whitefly population is small. In general, the older the plant when infected with virus or the later the onset of plant disorders, the less damage to the crop, so preventative action is critical. Prevention is also crucial in managing whiteflies in highly cosmetic crops such as ornamental plants, where even low numbers of whiteflies can affect marketability.
