Kifogyhat a Föld banánkészlete egy fertőzés miatt, Kolumbiában már válságban van a termesztés

A szakértők a genetikai módosításban és a vadon termő banánfajtákban látják a reményt.

Pusztító fertőzéshullám fenyegeti a világ legnagyobb banánültetvényeit. Kolumbia nemzeti vészhelyzetnek minősítette a szituációt, miután

egy veszélyes kártevőre, pontosabban gombafajra bukkantak a talajban.

Az úgynevezett Panama-betegség az 1990-es években támadta meg az ültetvényeket Ázsiában, Ausztráliában, Afrikában és a Közel-Keleten, ami a banántermesztés helyi krízisét eredményezte. Ekkor szerencsére Amerika, a legnagyobb banántermelő kontinens, érintetlen maradt.

A fuziáriumgomba - a 4-es típusú, azaz TR4-es fertőzés - csaknem 180 hektárnyi területet érint jelenleg, legalábbis eddig ekkora részen fedezték fel az élősködőt La Guajirában.

Azt kell tudni erről a fajta gombáról, hogy

a banán termését teljesen tönkreteszi: a gyökerein keresztül támadja meg a növényt, ezután bekerül a szöveteibe, eltömíti az edénynyalábokat, ezzel lényegében megszünteti a keringést - vagyis a gyümölcsnek annyi.
