Leptospermum typically produce solitary flowers, or in small groups of 2s and 3s or more, within the leaf axils. Healthy corms become infected from contaminated soil that contains mycelium and sclerotia. When harvesting the tubers choose a dryer period and be careful not to damage them. which attacks the stems causing the plant to wilt and topple over. Saunders Case Moth The genus Leptospermum was first recognized by Johann Reinhold Forster and his son Johann Georg Adam Forster when they published the name L. scoparium Forst. The young stems are covered with silky hairs at first and have a groove near the base of the petiole. Viola species are attacked by the Sawfly (Ametastegia pallipes)which eats the leaves skeletonising them.

The larvae emerge from their tunnels at night, to feed on the bark around the entrance holes. The caterpillar forms a cigar-shaped case from pieces of needles. Extensive feeding by a number of larvae causes dieback but normally, this is a minor pest. feeds on the old growth causing stunting of the host and the larvae overwinter in cocoons on the ground. ) .This recently introduced fungal disease in Australia (1993) affect plants by blackening the root systems and turning leaves yellow or purple. . The larvae feed beneath the bark, producing oval (in cross-sectioned) tunnels with much sawdust ("frass") around the entrance. Tsuga species are infected by Sapwood Rot or Butt Rot (Ganoderma lucidum) and (Coniophora puteana), which attacks the sapwood close to the bark, towards the base of the tree.

They tend to feed on the terminal shoots, and heavy infestations can defoliating young trees. von (1858), Catalogue of the plants under cultivation in the Melbourne Botanic Garden. Very hardy and can tolerate salt spray. This results in faster root development and less subject to diseases by fungi and bacteria. Dark spots appear on the pseudobulbs eventually causing extensive rot and killing the bulb. Species: Latin - laevigatum meaning (smooth), referring to the texture of the leaves. The cuttings must be potted up as soon as the roots developed, or a light application of liquid fertiliser can be applied. Most Leptospermum species are endemic to Australia where most are found in southern areas of the country and many make desirable garden plants.

Native To: Australia/New Zealand . Cotoneaster species are attacked by Webworm (Cremona cotoneaster) lava which skeletonises the leaves. These cuttings are an advantage where the plant uses the axillary bud at the base of the petiole for new shoot growth and maximises available propagation material, as each node will produce a new plant. Populus nigra 'Italica' is infected by the rust (Melampsora species) which forms pustules to form on the leaves turning them brown and causing premature leaf drop. ). 1. Spreading shrub or small tree 2.5 to 6.0 metres. Larva constructs large obvious shelters or bags using the twigs and leaves towards the end of the branches.

The infestation is not restricted to the leaves; all above ground parts of the plant are susceptible and infected plants transmit the fungus dispersing it by wind. Its antlers consist of two main beams from which the points emerge. dotted on the leaf, which may be obscured and when the leaf is crushed it is aromatic. The infection appears from spring to summer under humid low light conditions and turf that is under stress or with excessive nitrogen in the soil is more susceptible. Most fungus is specific to its host and normally will not infect other plant species. brown adult that is found in the warmer regions of Australia and is up to 20mm long.

At least one form with variegated foliage is in cultivation. It is commonly seen from temperate to tropical regions feeding on leaves of Eucalyptus, Callistemon and Epacris species. They are also prone to scale insects which is best treated by spraying white oil solution. As mentioned, they are happy to grow in moist soils, so with this cultivar, more is more. The commercial products have proven to work better than home remedies which include soap or chilli mixtures and hanging bags of human hair. The spores can be arranged in a structure such as a, or develop without an enclosed structure called a ". They are located in tropical rainforests, sclerophyll, heaths and woodlands in rich to poor dry soils. The head protrudes from the case to feed. Generally they are made up of branched threads called 'hyphae' and collectively form a vegetative body called 'mycelium'. The trunk is often gnarled, the bark flaky and shed in strips. The floral tube covers the ovary and may continue above the ovary summit and form a disk around the ovary. is a small larva to 12mm long and is brown with reddish brown longitudinal stripes. Tufts of hyphae develop in the stomates. Irisand Dietes species are very susceptible to the rust (Puccinia iridis). The yellow spores at the epidermal layer through wounds and germinate on mass causing the area to become soft and spongy. agropyri). This family has many attractive species and are extensively used in ornamental. Viburnum species are mildly affected by two types of rust (Coleosporium viburni) and (Puccinia linkii).
