There is another borer, ) which attacks any part of the plant from the trunk to the branches and is found on several. ) It deposits oval eggs that are tiny 0.50mm wide normally deposited in the leaf axil and change colour from white to red in the first 12 hours. If cactus or tree species are infected it is possible to cut out the infected area when. These plants are also susceptible to other leaf spots such as (. Normally occurs on Nelumbo species (water lilies). Active throughout the year in warm climates and are commonly found from tropical to sub-tropical and temperate regions. It is a solitary feeder eating entire leaves and is found from tropical to sub tropical regions. ) Vegetable Weevil (Listroderes difficilis) is found during cooler weather (spring or autumn). Many seeds have different methods of seed preparation for germination such as nicking or cutting the seed coat to allow water penetration, also placing seeds in hot water and allowing it to cool off.

Fraxinus species are infected by the leaf spot (Gloeosporium aridum) giving the leaf a scorched appearance as large blotches appear from the margin or apex and turn brown with a papery texture. Tilia species are attacked by the European Bark Borer (Chrysoclista linneela), which feeds on the bark and thew Linden Borer (Saperda vestita) that attacks the base of the trunk or roots. Does well in dry well drained soils which may be sandy, clayish or stony soils as long as they do not accumulate water and not compacted. species may be infected by several fungal leaf spots including (. It has scattered serrated light green leaves and the large yellow-green flowers heads appear from late summer to autumn. Resin oozing from a trunk. Vaccinium ovatum is infected by the leaf spot (Rhytisma vaccinii) and (Dothichiza caroliniana). As they are heavy producers of nectar, they attract many types of animals.

All photographs and data are covered by copyright. species are attacked by several borers such as the. ) Damaged branches may be removed, or tunnels plugged.
However, they are easy to cultivate and grow in the right conditions. Generally leaf spots appear on the juvenile or new leaves causing brownish spots that enlarge and may have a purplish halo around the margin. Improve the culture by feeding and watering the plant. Tip prune only. Varies with the insect concern. Some serrata varieties can grow as tall as 50 feet in height. Adults feed on nectar and cause little damage. Daphne species are infected by the leaf spot (Gloeosporium mezerei) and (Marssonina daphnes) both of which form thickish brown spots that are seen on both sides of the leaves. This fungus forms angular leaf lesions that produce fruiting bodies on the underside and is commonly found on Archontophoenix species. Banksia serrata. The leaves may also shrivel and die prematurely, during dry periods and small and large branches die. This infection is commonly found on newly laid turf but will also infect established lawns.

Winter Fusarium Leaf Disease in Turf Grasses can be minimised by aerating the soil, reducing thatch and avoid excessive nitrogen in the soil. The fruit are dehiscent or indehiscent follicle or drupe or achene with few or many winged seeds. Aspidistra species are infected by the leaf spot (Colletotrichum omnivorum) causing whitish spots on the leaves and petiole. Acer platanoides is attacked by the Leaf Stalk Borer (Nepticula albostriella) that tunnels into the petiole of the leaf turning it blackish and also attacks the fruit. Hedera species are infected by Phytophthora Blight (Phytophthora palmivora). The larva tunnels its way through roots or trunks depositing frass as it goes, then emerging from a second round hole. a New Zealand short lived moth that grows with a wing span of over 100mm (4in) wide laying eggs on the forest floor at night during spring. It is most prevalent during warm humid periods in soil with a high nitrogen level. Tree forms usually have a single trunk, while shrub forms have one or more stems at ground level. Tree injection is unsuccessful because the larvae tunnel into the woody part of the plant. Banksia are known to be fast-growing plants and do best when growing in sandy soil. species are susceptible to several fungal leaf spots including; Generally the circular leaf spots are brown and may have a yellow halo such as. Cissus and Grevillea species are susceptible to the Cissus Hawk Moth (Cizaria ardeniae).

Populus spp. The thick leathery lanceolate leaves have very sharply serrated margins that are slightly undulating. Control is difficult and generally the plants tolerate attack. This fungus courses spots to appear on leaves and mummifies and blackens immature fruit or rots mature fruit. species are damaged as the larvae bore into the new shoots normally during spring or during the rainy season. species are infected by a large variety of leaf spots, while other plants attract a specific leaf spot. Vaccinium ovatum is infested by the Azalea Stem Borer (Oberea myops). Plants that are stressed, are particularly venerable. appears as a small spot with a dark centre on the leaves and affects palms that are growing in shaded humid positions and normally control is not required, though infected fronds should be removed. This fungus forms yellow leaf spots that become hard with a raised with a blackish scab, which produces masses of powdery spores that are thread-like. 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. The larva also attacks recently fallen timber or existing dead plants. and infected plants wilt, collapse and die. Banksia marginata Cav..

Both the adults and lava cause damage, feeding on the plant during the night and resting at the base or under ground during the day. It is spread by wind currents from plant to plant and control methods include removing infected fronds and maintaining a drier atmosphere. They vary in size from small to large depending on the species. Entrance holes may be covered by a layer of chewed wood fragments ("frass"), silk webbing or exposed and the tunnels may be solitary or form galleries. Frosts and droughts rarely occur along the coast. century British botanist Sir Joseph Banks; 'serrata': saw-edged (refers to the leaf margin). There are specialised stem injecting equipment available for stem injections on larger trees. The life cycle is short and when conditions are favourable spores are splashed onto the foliage from the thatch, causing wide spread infection. ). This is a major economic pest for cultivated trees. However, should you suspect cinnamon rot it is vital to remove all parts of the plant and destroy them to avoid further infection. Collect and depose of fallen leaves otherwise control is not normally required.

Elm Borer (Saperda tridentate) adult is a greyish beetle with red bands and black spots on its wing covers and is up to 12mm long. Introduced non-indigenous trees, including over 100 pine and eucalypt trees, were overshadowing the plants and forming a thick leaf litter layer, reducing the rate of germination and growth of native remnant species. Many species of fungus overwinter in fallen leaves, remove and destroy any litter under the plant. These contain evergreen shrubs and trees with attractive foliage, brightly coloured flowering spikes and fruit cones with attractive shapes.

Deodar Weevil (Pissodes nemorensis) is brownish with an obvious snout feeding on the cambium layer and deposits eggs in the bark of the leader and branches. As Phytophthora species are most easily transported in infested soil quarantine is an essential component of control of the disease and it is for this reason many areas have hygiene protocols to stop the pathogen being introduced into an area. Stable, long lived. These may be in the form of black spots or brownish spots that converge killing the leaf.
