Liquid Copper Fungicide say can also be used as a treatment. C.fruticosa (formerly called C.terminalis) is indigenous to South­east Asia and India, and is found throughout the Pacific Islands. Also, often the land containing the ti plantations passed out of Maori hands. The cooked ti pore kept well, and was handy in times of war as emer­gency rations within the pa and as takeaways for war parties. Some sci­entists predict that at the present rate of loss, few cabbage trees will be left in Northland by the year 2000. They are often found in groves in the … this process was adopted during the month of November. The name referred to the tender, and usually very tasty, terminal bud of the palm which affords, in the words of one Jamaican explorer in 1756, “a tender green or cabbage.”, This was the usage adopted by Cook and Banks in their journals. New zealand’s original Poly­nesian settlers must have found the widespread distri­bution of cabbage tre. The darker the green the more Vitamin C, iron, and folate a leaf contains. Dr Beever offers two sugges­tions: the cabbage tree MLO may have arisen by mutation from the flax MLO, or it may be a totally new immigrant which has evaded quarantine controls and slipped across our borders. Simpson rejects the theory that cabbage trees are flowering them­selves to death. Over the past decade there have been further attempts to refine “lily” classification, and cabbage trees have been placed in the family Asphodelaceae (which includes the asphodels of Europe). Dusty grey cabbage aphids can be problem. And on flat land the trees are still actively cut down—if you’re making hay you don’t want a tree in the middle of your pad­dock.”. Using advanced molecular biology techniques, DSIR scien­tists began their search for the cabbage tree culprit. The indigenous varieties of ti were also adopted as an important food source by the Maori—espe­cially C. australis, C. pumilio and a mysterious plant which was culti­vated in Hawkes Bay, the Waikato,Taranaki and Whanganui. es a welcome sight. The South Island report quoted above describes a pit of two chains (40 metres) in length, and nearly two metres in depth, that took 20 men two days to dig and stack with fire wood. Whether C. fruticosa is native to these islands or was introduced is a matter of some debate, but there is little argument that the early Polynesian voyagers to New Zealand brought this important crop with them, along with kumara, taro, hue (the gourd) and aute (paper mulberry). Hosking says it’s hard to find evi­dence of it south of a line drawn across from Wairoa to Awakino. When Captain james Cook came upon “a cabbage tree which we cut down for the sake of the cabbage” at Tolaga Bay in October 1769, he was referring to a nikau palm, not the ti or Cordyline australis which now bears this common name. Genus Cordyline are palm-like evergreen shrubs or tree-like perennials, with rosettes or tufts of linear or anrrowly lance-shaped, leathery leaves, and terminal panicles of fragrant, cup-shaped flowers followed by small. It can, however, benefit a home landscape setting. Checklist of fungi on cabbage trees (Cordyline spp.) in 1845.” None had ever flowered. In pre-European times, the cultivation and preparation of the stem and rhizome for food was a major industry—one that was both time-consuming and labour-intensive. Why, they asked, had this tree, and an increasing number of other seem­ingly healthy members of the spe­cies, suddenly dropped their leaves and died. Rather, he suggests, it could be the natural response of a distressed tree to put all its resources into a mass flowering in a last desper­ate endeavour to reproduce before death. A year later William Colenso did the same. From the outset, though, DSIR scientists suspected a mycoplasma-like organism (MLO), as these microscopic entities, which fall somewhere between viruses and bacteria in the natural order, had already been identified in two related diseases: yellow leaf disease of New Zealand flax and lethal yellowing of coconut palms. Ti trees have a terrific ability to regenerate from any bit of root left in the ground -- Maori proverb: “Ka whiti te ti, ka wana te ti, ka rito te ti." and New Zealand flaxes (Phormium spp.) The microscopic pest affects other native plants such as karamu, black tree fern, kohuhu and puriri.The phytoplasma has also been found in strawberries in New Zealand, and in Australia, it is linked with diseases of grape and papaya.Dr Beever said that although the cabbage tree pathogen had been identified, many questions remained.It was critical to find the insect which carried the phytoplasma. Sudden Decline of cabbage tree Rees-George et al. Where areas are low in cabbage trees, DOC is encouraging the propa­gation and replanting of local off­spring—plants which, by virtue of adaptation, should have the best chance of survival in each particular location. “In like manner was used the tap root of the ti. Gordon Hosking, forest ento­mologist with the Forest Re­search Institute, Rotorua, has travelled the country investigating the distribution of the cabbage tree as part of the over-all study. there are so many different things you can add to … The roots, most plentiful near the surface, are 4-5mm thick and grow up to 10m in length.
