Kopretina obecn\u00e1: Vytrval\u00e1 invazn\u00ed rostlina<\/h2>\n\n

Identifikace<\/h2>\n\n

Kopretina obecn\u00e1 (Tanacetum vulgare<\/strong>) je vysoce invazn\u00ed vytrval\u00e1 rostlina, kterou lze snadno rozpoznat podle jej\u00edch charakteristick\u00fdch znak\u016f. M\u00e1 tmav\u011b zelen\u00e9, kapradin\u00e1m podobn\u00e9 listy se \u017elut\u00fdmi, knofl\u00edkovit\u00fdmi kv\u011btenstv\u00edmi, kter\u00e9 kvetou na stonc\u00edch dosahuj\u00edc\u00edch v\u00fd\u0161ky a\u017e 5 stop. Tato aromatick\u00e1 rostlina byla kdysi cen\u011bna pro sv\u00e9 l\u00e9\u010div\u00e9 vlastnosti, ale od t\u00e9 doby se stala hlavn\u00ed hrozbou pro severoamerick\u00e9 ekosyst\u00e9my.<\/p>\n\n

Invazivita<\/h2>\n\n

Kopretina obecn\u00e1 je plodn\u00e1 producentka semen a prost\u0159ednictv\u00edm sv\u00fdch oddenkat\u00fdch ko\u0159en\u016f se d\u016frazn\u011b \u0161\u00ed\u0159\u00ed. Tvo\u0159\u00ed hust\u00e9 porosty, kter\u00e9 mohou rychle p\u0159er\u016fst p\u016fvodn\u00ed vegetaci, \u010d\u00edm\u017e sni\u017euj\u00ed biologickou rozmanitost a zhor\u0161uj\u00ed prost\u0159ed\u00ed pro voln\u011b \u017eij\u00edc\u00ed \u017eivo\u010dichy. Toxicita rostliny pro \u010dlov\u011bka, kr\u00e1vy a kon\u011b d\u00e1le zhor\u0161uje jej\u00ed dopad na \u017eivotn\u00ed prost\u0159ed\u00ed.<\/p>\n\n

Odstran\u011bn\u00ed<\/h2>\n\n

Pokud se kopretina obecn\u00e1 usadila na va\u0161em pozemku, je nezbytn\u00e9 ji okam\u017eit\u011b odstranit. Jednotliv\u00e9 rostliny nebo mal\u00e9 skupiny lze odstranit ru\u010dn\u011b vykop\u00e1n\u00edm lopatou, p\u0159i\u010dem\u017e je nutn\u00e9 odstranit v\u0161echny ko\u0159eny. Tato metoda je v\u0161ak \u00fa\u010dinn\u00e1 pouze u mal\u00fdch napaden\u00ed.<\/p>\n\n

U v\u011bt\u0161\u00edch napaden\u00ed m\u016f\u017ee b\u00fdt nezbytn\u00fd \u0161irokospektr\u00e1ln\u00ed herbicid.

Se\u010den\u00ed p\u0159ed aplikac\u00ed herbicidu m\u016f\u017ee oslabit rostliny a sn\u00ed\u017eit mno\u017estv\u00ed pot\u0159ebn\u00e9ho herbicidu.<\/p>\n\n

Prevence<\/h2>\n\n

Abyste zabr\u00e1nili \u0161\u00ed\u0159en\u00ed kopretiny obecn\u00e9, je nezbytn\u00e9 odstranit rostliny p\u0159edt\u00edm, ne\u017e vytvo\u0159\u00ed semena. To lze prov\u00e9st jejich od\u0159\u00edznut\u00edm nebo vytr\u017een\u00edm p\u0159ed nebo b\u011bhem obdob\u00ed kv\u011btu v l\u00e9t\u011b. Pokud k odstran\u011bn\u00ed dojde pot\u00e9, co se vyvinuly semen\u00edky, mohou v n\u00e1sleduj\u00edc\u00edm roce vykl\u00ed\u010dit nov\u00e9 rostliny.<\/p>\n\n

Kopretinu obecnou lze od star\u010dku hajn\u00edho (Senecio jacobea<\/strong>) odli\u0161it podle jej\u00ed jedine\u010dn\u00e9 struktury kv\u011bt\u016f.
