This normally occurs in wet soils and is detrimental to the plants life. adult is a moth that produces caterpillars that construct a small elongated shelter from pieces of the host's leaves and enlarges to 80mm long, as the lava grows. The lava feed mainly on the roots of grasses. Runners from the surrounding healthy turf will help with recovery and all signs of the problem disappear by mid summer. causes leaves to curl then turn brown and the sap wood may also turn brown or black. This family of insects is found world wide, including Australia. Under severs conditions the mycelia consume all available nutrients resulting in the death of the turf. A fungal problem involving at least two species (, Host plants include Lombardy Poplars particularly. ) Betula species may be infected by Leaf Rust (Melampsoridium betulinum) that forms reddish-yellow spots on the leaves and heavy infestation can defoliate the tree. which forms brown or bright orange spots on the leaves or twigs and can defoliate the tree.

Always read the label for registration details and direction of use prior to application of any chemicals. Artemisia species are infected by the rust (Uromyces ari-triphylli) which is a systemic disease that is transmitted through seeds. which forms yellowish pustules on the leaves that develop turning the leaf brown. It then overwinters in its case attached to the twigs and the moth emerges in early summer. This leaf rust appears on the underside of the leaves (preferably older leaves) forming dusty brown pustules and is a serious problem. The larvas cause death of grasses as their roots have been severed from their stem. Flowers 15-20 mm diam., borne on short axillary shoots; bracts broad, brown and often persisting about the flowers; hypanthium . The regular flowers are hermaphrodite or sometimes unisexual and may be axillary, solitary, or arranged in cymes, umbles, terminal spikes, racemes or panicles. Under commercial conditions stock may be sprayed with a fungicide such as oxycarboxin. The larvae pupate in the soil and the beetles emerge in summer with usually one generation per year. Place in a well-drained media and maintain a high humidity. Damaged trees should have the wounds dressed and sealed as a preventative measure particularly for Dieback in Camellia. occurring in coastal regions but is not normally detrimental to the plant. ) brown adult that is found in the warmer regions of Australia and is up to 20mm long.

Calendula species may be infected by the Rust (Puccinia flaveriae). Cut the leaf blade in order to obtain new plants during the growing period of the plant. The object of the structure is to create an environment where the temperature and humidity can be controlled. These markings enlarge before the pustules form and in severs cases the lawn has a yellow, red or brown appearance. Ribes species are infected by the rust (Cronartium ribicola). Cut off and destroy any infected branches, fallen leaves and remove heavily infected plants. The mycelia expand radially in the turf feeding on soil nutrients and organic matter with water present. ) The corresponding position on the upper leafs surface turns yellow eventually causing the leaf to wilt and die.
