such as cultivating the soil regularly with added animal manure and other organic substrates to ensure there is good drainage will also help to minimise the impact of the disease. Saw Banksia, Old Man Banksia, Red Honeysuckle. Acer species may also be attacked by several borers including the Flat Headed Borer (Chrysobothris femorata), a 25mm long lava of a coppered coloured beetle, that tunnels galleries under the bark girdling the trees The Sugar Maple Borer (Glycobius speciosus) which girdles branches killing them and the Leopard Moth (Zeuzera pyrina) lava that tunnels large holes into branches making them structurally weak. Poa species and other cool season grasses are infected by Winter Fusarium Leaf Disease (Fusarium species), which causes small pale spots that are water soaked to appear on the leaves that turn red-brown. There are many crop plants and ornamentals that are affected by this larva. that are free or united and are arranged in a single whorl, petaloid and valvate in bud joined when young and separating as the tube splits down one side. After they pupate in the tunnel they emerge through small round holes, commonly many together on the trunk. It flowers well in cultivation and flowers attract many birds. is a small beetle up to 3mm long and lays its larva in excavations in the bark. and heavy infestation may kill the tree. ) is infected by Phytophthora Blight, black flag disease (. The leaf forms light grey spots with no definite margin and mature to brown. On inspection the roots show signs of decay. NSW subdivisions: NC, CC, SC, CT Affected leaves are destroyed as the infection spreads. Leaves alternate, ± crowded, oblong to narrow-obovate, 5–20 cm long, 15–40 mm wide, apex truncate but with a short mucro, base attenuate, margins ± toothed but entire for 1–5 c. from base, lower surface rusty-tomentose but becoming ± glabrous. A leaf may have more than one spot develop on its surface and normally appears on scattered leaves throughout the tree. The margins are serrated, less coarsely than those of Banksia serrata. It has scattered serrated light green leaves and the large yellow-green flowers heads appear from late summer to autumn. Acacia species are susceptible to attack from the Wattle Web-covering Borer (Cryptophasa rubescens), which weakens and causes die back of branches. The lava may feed solitary or in small groups on leaves leaving only the midrib. Palms such as Archontophoenix, Caryota, Chamaedorea, Cocos, Dypsis, Howea, Liculia, Linospadix, Livistona, Phoenix, Ptychosperma, Rhapis, Roystonea, Syagrus, Washingtonia and Wodyetia species are susceptible to several fungal leaf spots including; (Bipolaris spp. attacking the stems just below the soil level causing the plant to topple and if infection occurs as the leaves are emerging the base of the infected leaves which collapse remain attached to the bulb. The leaves may also shrivel and die prematurely, during dry periods and small and large branches die. infects the roots and stems turning them brown and seeds are also attacked causing decay. Mahogany Shoot Borer (Hypsipyla grandella). ). The leaves on affected branches turn yellow, wilt then die and mildly affected trees may survive. Corn Borer feeds on flower buds and leaves resulting in there death, after which the larva tunnel down the stem causing wilting. In some coastal areas it is a shrub to 3m, and there is also a prostrate form. These insects have a Holometabolous life cycle, ie. The adult is a greyish-brown moth with a wingspan up to 45mm with the wings and veins distinctly overlayed in black. Wisteria species are infected by three fungal leaf spots (Phyllostica wisteriae), (Septoria wisteriae) and (Phomatospora wisteriae). Generally leaf spots appear on the juvenile or new leaves causing brownish spots that enlarge and may have a purplish halo around the margin. These attacks tend top take place later in the season and normally not detrimental to the tree. The symptoms of the disease are often very difficult to differentiate from drought symptoms, mainly because the affected root system prevents the uptake of moisture from the soil. Chamaecyparis species may be infected with the Root Rot (Phytophthora lateralis) that attacks roots, trunk, stems and leaves. This fungus courses spots to appear on leaves and mummifies and blackens immature fruit or rots mature fruit. Banksia species are attacked by the Banksia Longicorn (Paroplites australis) which is a reddish brown beetle to 50mm long with equal length antennae and produces a yellowish fleshy (grub-like) lava, that is legless and tapers towards its tail. Generally a healthy plant can tolerate fungal leaf spot attack, though it may make the plant look unsightly. species are infected by four fungal species including (, species are infected by several fungal leaf spots including (, species are also infected by the leaf spot (. ) a greenish lava up to 40mm long that tunnels down the centre of branch tips. species), forming dark rounded or angular spots.
