Amsterdam: Elsevier Academic, 2005. It is a soil pathogen which infects the root system and goes on to colonise the plant through the vascular system – hyphae of the fungus can even reach the leaves. The disease has decimated crops and has threatened an estimated 80 percent of the world’s banana crop. Although the pathogen probably originated in Southeast Asia, the disease was first reported in Australia in 1876. It was then reported from Panama in 1890. 5th ed.

Banana plantations suffer from many serious diseases such as Fusarium wilt or panama disease, Cercospora leaf spot or Sigatoka, bacterial wilt or Moko disease, burrowing nematode infestation, Bunchy top (a nanavirus), anthracnoseThe conspicuous symptoms of Fusarium wilt appear on at least 5 months old banana plants although 2-3 months old plants are also killed under highly favorable conditions for disease development.The first internal symptoms develop in feeder roots, the initial sites of infection.They progress to the rhizome and are most prominent where the stele joins the cortex.The pseudo stem is colonized, faint brown streaks or flecks become evident on and within older leaf sheaths.Eventually, large portions of the xylem turn a brick red to brown color.The first external symptoms of Panama disease are a yellowing of the oldest leaves or a longitudinal splitting of the lower portion of the outer leaf sheaths on the pseudostem.This is followed by a wilt and buckling of leaves at the petiole base.In some cases, these leaves remain green. It is economically damaging to the banana industry, and the threat of more virulent strains or mutations to damage previously resistant crops is of major concern.

"FUSARIUM WILTS OF POTATO, THEIR DIFFERENTIATION AND THE EFFECT OF ENVIRONMENT UPON THEIR OCCURRENCE." ), is one of the most notorious of all plant diseases. 1981. Print.Dreistadt, S.H.
Yield losses of effected crops can be high, up to 45% yield loss of tomato crop has been reported in India. Because F. oxysporum is so widespread, it is a significant problem in many crops.
Certain pathogenic strains of Fusarium wilt (Panama disease) is the most serious disease of banana, threatening 80% of the world's banana production, most of which is planted with the susceptible Certain rare soils are said to be "Fusarium-suppressive," that is, given two soils with high populations of infective Snyder, W.C. and Hansen, H.N. and Clark, J.K. 2004. As the disease progresses, younger and younger leaves collapse until the entire canopy consists of dead or dying leaves.is soil-borne through its thick-walled chlamydospores.These spores can remain dormant for several years after the host dies.The infection always occurs through injured lateral roots.After entry the lateral roots the fungus proceeds to rhizomes where it develops extensively in the vascular tissue before passing up the vascular system into the pseudo stem and other older leaf petioles.The disease spreads mainly by contact of the root system of adjacent healthy plants with spores released by the diseased plants.The use of infected planting stock is another source of fresh introduction and spread.Sanitation by immediate removal of diseased plants with surrounding soil from the field.Heat treatment of soil was used recently to manage spread of the pathogen in different parts of India.Arbuscular mycorrhizal fungi have been shown to reduce disease severity in short-term green house.Tissue-cultured plantlets are free of bacterial, fungal and nematode pathogens and should be used to establish new plantings whenever possible.Use of plant injection @ 2 per cent Carbendazim plus Agallol or Aretan soil drench is claimed as an effective method of freeing the planting stock of the pathogen and protection of new plants.The additions of highly antagonistic organisms to soil around banana roots give protection to plants against wilt. One control method is to improve soil conditions because There is growing interest in using Fusarium wilt as a form of biological control.
