Viola species may be infected with the Scab (Sphaceloma violae) which attacks all parts of the plant including the seed capsule forming yellowish spots that turn brown and in leaves fall out. . It is not a true scale insect and is simular to mealy bugs. Young plants may be killed. Cornus species are infected by Crown Canker (Phytophthora cactorum) and in this case the tree is partially infected initially with one side producing smaller leaves that turn reddish in late summer. Each female lays up to 100 eggs that hatch in 7-14 days, with several generations appearing throughout the year. Root Rot (Phytophthora richardiae) infects Zantedeschia species causing the leaves to turn yellow, wilt and die. Generally they form black or white spots that may be faded and produce masses of spores in the thatch during late summer, under humid conditions. 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. is gregarious, brown with a large head and tufts of hairs that line the slender body. The large female adult moth has a stocky body and generally slow moving, the male is smaller. species are infected by a large variety of fungal leaf spots including (, species are infected by the fungal leaf spot (. Commonly killing the host. ) This fungus courses spots to appear on leaves and mummifies and blackens immature fruit or rots mature fruit. which first forms yellowish spots up to 25mm (1in) across that become black. This fungus forms angular leaf lesions that produce fruiting bodies on the underside and is commonly found on Archontophoenix species. that causes the leaves to fade and plants to wilt. Saintpaulia, Dianthus, Gypsophila, Limonium and Anemone species are infected by Root and Crown Rot (Phytophthora nicotianae). is a pale yellow circular scale up to 3mm across and is found in dense colonies on the stem or leaves. ) Chamaedorea metallica (Metallica Palm) is an ornamental indoor house plant. The large female adult moth has a stocky body and generally slow moving, the male is smaller. ) Palm Leaf Spot (Pestaloptiopsis species) 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. Chlamydospores, specialised survival spores. It is also a popular house plant. Open or dense, moist woodland or forest; to 500 m elevation; often on limestone. Orchids such as Cattleya, Cymbidium, Cypripedium, Dendrobium, Epidendrum, Oncidium, Paphiopedilum, Phalaenopsis and Zygopetalum species are infected by Phomopsis Rot (Phomopsis species). that forms light brown spots on the upper-side of the leaf and on the stem. The symptoms include small violet to brown spots appear on the upper surface of the leaf and correspondingly yellowish brown on the underside. It … species are infected by a large variety of leaf spots, while other plants attract a specific leaf spot. Normally the make the tree look poorly but have little effect on its growth.

Cultivation and Propagation: It is cultivated in tropical and subtropical regions for understory plantings in the moist, shaded garden and ideal as houseplants. The adult moth is dull grey with brown bands and spots on the wings, appearing in early summer. There are of great horticulture importance and are used in many gardens. Cactus Scale (Diaspis echinocacti) has a circular greyish female and a narrow white male scale and is commonly found on house plants. This charming dwarf species takes up very little room and adds a good deal of tropical interest to even the smallest gardens.Soil: It likes a humus-rich loamy soil, but is adaptable to clay and sand bolth. There are many fungal leaf spots that infect this plant including (, ) which forms small brownish spots that have yellowish margins and has black fruiting bodies that forms coils of spores. These viruses are found from tropical to temperate climates. species are attacked by two spotted mite and banana spider mite damaging foliage and fruit. They initially appear on the undersides of leaves. are susceptible to Helminthosporium Disease. ) Dusting with wettable sulphur may also prove effective. Palms are also infected by the Brachybasidium Leaf Spot (Brachybasidium pinangae). Normally found on Iris species. Magnolia species are susceptible to many species including (Alternaria tenuis), (Mycosphaerella milleri) and (Phyllosticta species). Oblique-banded Leaf Roller (Choristoneura roseceana) lava feeds on the leaves and forms a nest by drawing the leaf margins together using silk threads. This casual organism commonly occurs after flowering killing the leaves but will not infect the bulbs. species) which forms circular brown spots on the fronds and heavy infection can defoliate a plant. Infected leaves die and fall from the plant. Avoid over watering the soil and observe hygiene in regards to tools, containers or shoes to reduce spreading the infection. species). Callicarpa species may be infected by the leaf spot (Atractilina callicarpae) forming irregular brownish spot or (Cercospora callicarpae) which can defoliate the plant in subtropical climates. On the ground they can be squashed or collected and placed in a bucket of soapy water. It is found in warm temperate to sub tropical regions and dispersed in infected soil or plant material. 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. After a couple of seasons the tree becomes completely infected with poor top growth and an inconspicuous canker develops at the base of the trunk. diseases is prevention primarily because it is extremely difficult to control, diseases after they are established in the plant. This is a problem in the apple growing areas of North America. Flat Brown Scale on The spots may leave holes, perforating the leaf or expand with pale green to yellowish margins and when the holes merge the leaf normally dies. Seeds are easiest to germinate if planted within 4-6 weeks after the fruit is ripe but germination can still be erratic. adult is a large butterfly with a wing span up to 110 mm with four long tapering tails and the rear of the wings. It injects a toxic substance into the host as it sucks sap causing the death of the branch. 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 legged nymphs are normally arranged from head to tail along the mid rib of the leaf, and may move to a new position to feed. Vinca species are infected by the soil born Root Rot (Pellicularia filamentosa) which rots the stems and roots. Hi, there are three leaf variations of Chamaedorea metallica: - entire leaf (common form), - partially split leaf - and split leaf. They excrete honeydew and attract sooty mould and are found on Acacia and Acronychia species. This large yellow and black Caterpillar grows to 76mm long and attacks the leaves. It can be identified by pink, cotton-like mycelium and the plant prefers cold wet weather. ) ). are light brown up to 0.5mm long, flat and closely attached both sides of the leaf and causing yellowing of the foliage. ) Stems and petioles can be girdled killing the upper part. These are the fungi responsible for cell leakage as in rot. The spores can be arranged in a structure such as a sporangia or pycnidia or develop without an enclosed structure called a "conidia". are also available commercially to control the Two-spotted Mite only on a large scale, as they require ample mites to survive. This infection normally spreads quickly throughout, killing the tree in one to two seasons. adult females are obvious with large group of eggs that are white or cottony-like, and the tiny young light green scales are flat and oval-shaped up to 2mm long.

As a houseplant, it thrives with 10-12 hours/day of artificial light.Wind resistance: It does best protected from drying winds.Aerosol salt tolerance: High.Hardiness: These palms are moderately hardy in the landscape in USDA zones 9-12. Chamaedorea metallica. both of which form thickish brown spots that are seen on both sides of the leaves. Palm seed should be sown as soon as possible after collection as the viability period is short, ripe mature fruit is essential. This method is normally carried out with medium to large seeds such as woody plants and plants that are difficult to transplant. It can also be propagated by division of the root mass. Two-spotted mites spread by crawling between nearby plants or movement of dead leaves. Other leaf spots include (monochaetia desmazierii) and (Marssonina juglandis). Larger seeds may be covered with media or a hole is dibbled and the seed is placed in the media. Indoor specimens benefit greatly from daily misting. which causes chlorotic spots that may be encircled by yellow rings. in domestic and commercial situations devastating lawns. Once established it has a high water requirement (Scale: 3-drops from 3), and responds to an occasional deep watering during dry periods and mulching when young. Leaf Blotch (Guignardia aesculi) forms small or large water soaked spots that are reddish with a bright yellow margin and form black fruiting bodies in the centre. that is commonly mistaken as a fungal problem causing translucent spots that coalesce and involve the entire leaf. Affected leaves are destroyed as the infection spreads. There is also a variety that has pinnately compound (feather shaped) with 4-7 linear or S-shaped leaflets. Little is known about this problem, though it affects a wide range of plants including. Orchids such as Cattleya, Cymbidium, Cypripedium, Dendrobium, Epidendrum, Paphiopedilum, Phalaenopsis and Zygopetalum species are infected by several leaf spots including (Cerospora, Colletotrichum and Phyllosticta species). There is obvious vascular discoloration which is very dark. The parlor palm is one of the most heavily sold houseplant palms in the world. As the fungus spreads the leaf dies but remains attached to the tree and this infection is commonly found on, ) forms small or large water soaked spots that are reddish with a bright yellow margin and form black fruiting bodies in the centre. Syringa species are attacked by up to six species of leaf spot including (Cercospora lilacis) and (Phyllostica species). The tip borer Cotton tipworm (, ), Rough bollworm (Earias huegeliana) which feeds on young stems, flowers and seeds. species), forming dark rounded or angular spots. The female moth uses a ovipositor to lay up to 500 eggs in groups of five amongst the crevices of the plant. in order to contain it. which are olive-brown caterpillars that form web nests in the leaves. ) Passiflora species are infected with many types of leaf spot such as (Alternaria passiflorae). The inflorescence is simple or branched into a huge panicle and normally arises from the leaf bases and forms with a protective overlapping woody bracts that remains until the flowers developed. They are found on. This infection normally spreads quickly throughout, killing the tree in one to two seasons. Plants with soft-textured foliage (eg vegetables, some indoor plants) are preferred, but trees and shrubs are commonly attacked. The distinctive petiole is armed or unarmed with spines or teeth and leaf scars or leaf bases may be persistent on the trunk. This is the same fungus that causes Damping-off. which has yellow and black lines down its body is up to 50mm long and eats the leaves or flower buds. Metallica Palm Tree - Chamaedorea metallica Metallic Palm description The easy to take care of Chamaedorea metallica or better known as the Miniature Fishtail is a Mexican native, mostly found as a rainforest understory palm tree.

Tea-tree Scale (Eriococcus orariensis) are a creamy blue colour normally packed along the branches and are plump and rounded to 4mm across. Carpinus species are infected by the leaf spots (Gloeosporium robergei), (Gnomoniella fimbriata) and (Septoria carpinea), all are minor infections not normally requiring control. Dark spots appear on the pseudobulbs eventually causing extensive rot and killing the bulb. A pest in North America of Oaks. All of the plants in PlantFile are fully documented covering an overview of the plant that includes a description, natural habitat and how the plant is commonly used. These may be in the form of black spots or brownish spots that converge killing the leaf. It prefers a shaded protected position that tends to be cool with wind, frost and drought protection. There is another fungus that is simular Helminthosporium Blight (Helminthosporium dictyoides) that infects Poa, Festuca and Agrostis species. Bibliography: Major references1) Forest & Kim Starr Chamaedorea metallica (metal palm tree). It is one of several species with leaves that are harvested as xate.. Generally light brown to purplish or blackish spots appear on the leaf and form concentric rings of fruiting bodies. This fungus attacks the needles and spur shoots turning them yellow at first then brown after which small black fruiting bodies appear on the leaves during winter. Infected leaves should be removed and burnt. If disturbed the larva drop to the ground and curl up, "faking death"  The larva pupate in the soil. All cause spotting or blotching of the leaf surface; remove and destroy infected parts. Verbena Moth (Crambodes talidiformis) lays its eggs on the outside of the plant and the small green caterpillar that attacks seed pods by entering and eating the contents. is known by several common names depending on which plant is being attacked and they have various symptoms. This weakens the wood and in severe infestations may kill the tree. Circular or angular dark spots appear on the leaves and are surrounded by necrotic areas that are yellowish. Dimethoate will reduce numbers; however, Two-spotted mites are resistant to insecticides in some areas. Eucalyptus species are infected by many fungal leaf spots such as (Mycosphaeralla species), (Hendersonia species) and (Monocheatia monochaeta). Control requires removal of infected foliage or the spraying of a fungicide and fungicides should not be used during the fruiting period. which forms a dark basil stem rot generally on damaged plants and produces orange-pink spores. This will reduce the infection rate of the plant. Catalpa species are attacked Catalpa Sphinx (Ceratomia catalpae). White Tussock Moth (Hemerocampa leucostigma) produces lava that is up to 50mm long. ). These caterpillars defoliate the tree but cause no long term problems. These are the fungi responsible for cell leakage as in rot. Spruce Budworm (Choristoneura fumiferana) is a reddish brown with a yellow stripe on its side and chews on the opening buds and the needles of the host. ), which appear as greyish spots up to 20mm (1in) across with concentric rings and black fruiting bodies. After a couple of seasons the tree becomes completely infected with poor top growth and an inconspicuous canker develops at the base of the trunk. Many species are infected by the Bleeding Canker including Acer platanoides, Acer rubrum, Acer pseudoplatanus, Acer saccharinum, Betula species, Liquidambar styraciflua, Aesculus x carnea, Tilia, Salix and Quercus species. It has a red head with a yellow body that is marked in black and has four tufts of hair. Black Root Rot (Chalara elegans).This recently introduced fungal disease in Australia (1993) affect plants by blackening the root systems and turning leaves yellow or purple. This zone may be affected by the monsoon or have high rainfall periods. The life cycle is short and when conditions are favourable spores are splashed onto the foliage from the thatch, causing wide spread infection. This may be seen on certain branches of the tree and on inspection under the bark the sapwood reveals brown streaks. Other plant foods include. ) Chamaedorea metallica Metallic Palm, A lesser known relative of the parlour palm, but just as easy. both are of minor importance not requiring control. 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. When found as Phytophthora Leaf Spot or Blight, angular spots appear with water-soaked margins as in Cordyline and Philodendron species. Aloe, Astrophytum, Copiapoa, Echinocactus, Espostoa, Ferocactus, Gymnocalycium, Kalanchoe and Schlumbergerera species are infected by Bipolaris Stem Rot (Bipolaris cactivora). It infects grasses particularly Poa pratensis. The fungus entered the lower trunk normally as a result of mechanical damage (lawn mower). Generally they are made up of branched threads called 'hyphae' and collectively form a vegetative body called 'mycelium'. Related Plants. which curls the leaves and forms reddish blisters. Corms on the outer ring of the patch that are partially infected forming a felty mass of violet threads on the corm scales. "Field Guide Palms Americas" 1–352.

Control methods include physically removing damaged pads and allowing the Sun to heal wounds. Damaged trees should have the wounds dressed and sealed as a preventative measure particularly for Dieback in Camellia. Large infestations can completely stripped a tree and control is carried out by spraying. ) Commonly occurring in wet soils. Also known as the red spider mite. The small lava are up to 15mm long, green with white lateral bands and feed on the leaves at night in small groups, hiding under the leaves during the day. MEXICO. A wide range of plants are attacked by the Red Spider Mite including annuals, fruit trees and vegetables, ornamental shrubs and trees. A variety of birds also attack scales. There are many ornamental and native plants that are hosts to a wide range of fungal leaf spots. This palm has a foliage with a dark metallic blue-green sheen hence the common name Metallica Palm. Plants cannot be cured of this disease and it is important to maintain healthy mother stock for propagation by isolating it from infected stock. The International Palm Society, Lawrence. affecting the lower stems and is not commonly seen. ) There is another fungus that is simular, species and occurs at during periods of high temperature. is enormous and is still not well understood but includes many Australian native plants, species, conifers, cabbage tree and strawberries. This Metallic Palm is grown for its attractive foliage.          Leaves generally turn brown from the apex or margins turning brown or spots appear on the leaf surface and leaves become yellow before withering and dieing. ... Propagation Pests and diseases Varieties Gallery. Control methods include sprang fungicide on leaves or reducing humidity and avoid wetting the fronds. It is difficult to identify specifically as other pathogenic root diseases and nutritional deficiencies have simular characteristics. There are several other fungi including (Cladosporium species) and (. Propagation: Metallic palm can be propagated by seeds. The pathogen also produces chlamydospores, specialised survival spores that allow it to survive in the soil for extended periods of time. It is capable of defoliating large trees and is a major problem for several species. Deter Potato Gangrene by planting clean stock and be careful not to damage the crop when weeding. Healthy corms become infected from contaminated soil that contains mycelium and sclerotia. ) Casuarina and Allocasuarina species may be attacked by the Casuarina Scale (Frenchia casuarinae), a black hard scale that is upright to 4mm with a pinkish body. Jump to: navigation, search Chamaedorea metallica subsp. are susceptible to several fungal leaf spots including (. Vaccinium ovatum is infected by the leaf spot (Rhytisma vaccinii) and (Dothichiza caroliniana). The larva is very destructive in northern hemisphere coniferous forests. ) Populus species are infected by several fungal leaf spots including (Ciborinia bifrons, Ciborinia confundens), and (Mycosphaerella populicola). Red Humped Caterpillar (Schizura concinna) is a lava has a red head and humps with yellow and black strips on the body. The leaves may also have these symptoms but is not commonly seen. The fruit and stems are also infected causing them to turn brown-black and whither. 7 implicated). Normally the winged or wingless males are mobile and only soft scales produce honeydew. The distinctive petiole is armed or unarmed with spines or teeth and leaf scars or leaf bases may be persistent on the trunk. Summer temperatures and humid with mild winters. Carya species are infected by several leaf spots including (Gnomonia caryae) that infects leaves with irregular reddish spots on the upper surface with corresponding brown spore producing spots on the underside. The seed must have no dormancy-inducing physiological, physical or chemical barrier to germination; also the seed must be nondormant. It is normally found in colonies on the small branches and twigs of shrubs. It tolerates warm temperate climates and coastal regions but must be kept moist. ). Found over much on mainland Australia. The leaf then becomes dried, brown and dead commencing from the margins, eventually the leaf dies. Roots become dark and the rot can extend up the stem. Seeds are easiest to germinate if planted within 4-6 weeks after the fruit is ripe but germination can still be erratic. In order for a seed to germinate it must fulfil three conditions. Orange to red flowers are produced in spring and are followed by black berries. is a caterpillar up to 60 mm long and is brown with black and white markings on its sides and when disturbed it arch backwards and reveal an extruded red underside, close to its head. Campsis species may be infected by several fungal leaf spots including (Phyllosticta tecomae), (Septoria tecomae) and (Cercospora duplicata). Spruce Spider Mite (Oligonychus ununguis) is a tiny greenish black adult which lays eggs on twigs where they overwinter. There is no chemical control, nitrogen fertiliser masks the symptoms and complete fertiliser encourages stronger roots to fight the disease. Spraying should be carried out as a last resort as many predators are killed during the operation and spraying can have the opposite effect by increasing numbers in the long term. Erica species are attacked by several species of scale including, Greedy, Oleander and Oystershell scale. which may cause considerable damage during wet periods. The adults are important pollinators of many Australian native plants. It is most prevalent during warm humid periods in soil with a high nitrogen level. All rubbish around plants and glasshouses should be cleared as certain moths overwinter in such places. 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. species). by forming brown spotting and wilting that appears at the base of the plant then extends towards the top. This disease forms deeply sunken reddish brown areas that become corky and produce a greenish fungal growth. ). Leaf Skeletonised. The plants aren't clumping by nature but grown in clumps for aesthetic reasons. Sedum species can be infected by up to three Stem Rot fungi including (Colletotrichum species), (Phytophthora species) and (Pellicularia filamentosa). 1995. is a lava has a red head and humps with yellow and black strips on the body.
