Hibiscus rosa-sinensis, Hibiscus syriacus and Hibiscus tiliaceus are susceptible to several fungal leaf spots including (Ascochyta abelmoschi), (Cerospora kellermanii) and (Phyllosticta hibiscina). Symptoms include the needles becoming yellowish at the apex and extending down the needle and spreading to others during moist spring weather turning them brown. This is a casual fungus that attacks the epidermal layer of the leaf, forming circular spots that are up to 25mm across and are often restricted by the main vein. Cynodon dactylon, Pennisetum clandestinum and many other Turf Grasses are susceptible to Helminthosporium Disease. species) which causes the foliage to turn black and limp.

Eucalyptus, Acacia species and many ornamental such as Acer species. In some forms, the leaf edges are wavy. Banksia species may be attacked by the Banksia Borer (Cyria imperialis). The pale yellow flowers occur through autumn and are followed by woody cones shedding seed in late spring early summer. This fungal attack normally occurs on plants in poor health and can be a serious problem early in the season seriously damaging stock. Woody stems bearing long, leathery, linear to linear-oblong, usually distinctively lobed or toothed leaves; cone-like (or head-like) cylindrical spikes of many densely packed, irregular, elongate flowers; perianth tube short; 4 slender perianth segments, each bearing 1 stamen at its tip; 1 style, extended in opened flowers, giving spike a bottlebrush appearance. Phytophthora are fungal-like organisms that are related to some protozoa and algae; they are microscopic and cannot be observed by the naked eye. When the larva emerges they bore galleries in the bark and tend to be more prevalent in stressed or recently transplanted plants. The black fruiting bodies appear as dots in the centre of the spot. eats circular holes through the sap wood and heart wood reducing the structural strength of the tree. No effective biological control though certain species of trees exude gum or resin sealing the holes and limiting the activity of the larvae or causing its death. In 3 to5 days the larvae emerges and can grow to 25mm long and is brownish white when young and maturing to bluish with a brown head capsule. causing loss of foliage, death of the upper branches and cankers on the trunk. It establishes in 2 to 4 years and is fire resistant. The most effective control for all Phytophthora diseases is prevention primarily because it is extremely difficult to control Phytophthora diseases after they are established in the plant. Pockets of sub-tropical climates exist within coastal warm temperate zones. The adult grows to 18mm long and its thorax forms an outgrowth that extends over its head making the beetle to always look down. ) Dieback Borer (Platyomopsis armatula) adult is a grey-brown beetle up to 20mm long with small lumps on its wing covers and long antennae.

The symptoms include foliage turning greyish towards the top, and then the plant wilts then dies with evidence of infection at the base. Infected leaves die, then fall and the branchlets wilt. Sowing seeds in a flat or germinating bed, through which seedlings are pricked-out then, transplanted into another flat with wider spacing or directly to an individual pot. Stressed or damaged plants are more susceptible to infestation and may display branch die-back; occasionally the larvae may ring-bark the trunk. Ulmus and Acer species are also infected by (Phytophthora cactorum) and this is known as Bleeding Canker. Many plants are attacked especially in the, ) forms a small reddish brown spots that are boarded in light green, and as they develop in size the leaf curls and dies from the margin inwards. and the result of the damage is not evident well after the insect has moved on. The cream coloured lava emerges in spring after rain and feed on the lower leaves forming irregular holes or chewing holes in stems.
