Chrob\u00e1k zemiakov\u00fd (Leptinotarsa \u200b\u200b\u200b\u200bdecemlineata) je postrachom mnoh\u00fdch z\u00e1hradk\u00e1rov. Ke\u010f pruhovan\u00e9 chrob\u00e1ky a ich nen\u00e1sytn\u00e9, \u010dervenkast\u00e9 larvy za\u010dn\u00fa po\u017eiera\u0165 listy zemiakov, z \u00farody \u010dasto ve\u013ea nezostane.<\/p>\n\n\n\n
Na\u0161\u0165astie sa nemus\u00edte uchy\u013eova\u0165 k chemick\u00fdm pestic\u00eddom. Existuj\u00fa vynikaj\u00face, \u010disto organick\u00e9 sp\u00f4soby, ako chr\u00e1ni\u0165 svoje zemiaky. Tu je 5 overen\u00fdch met\u00f3d, ako udr\u017ea\u0165 va\u0161u z\u00e1hradu bez jedov:<\/p>\n\n\n\n
Ako to funguje: Pravidelne kontrolujte rastliny zemiakov od jari (ide\u00e1lne r\u00e1no, ke\u010f s\u00fa chrob\u00e1ky e\u0161te leniv\u00e9). Zbierajte dospel\u00e9 chrob\u00e1ky a larvy.<\/p>\n\n\n\n
D\u00f4le\u017eit\u00e9: Nezabudnite skontrolova\u0165 spodn\u00fa stranu listov! Tam s\u00fa pripevnen\u00e9 n\u00e1padn\u00e9, oran\u017eovo\u017elt\u00e9 vaje\u010dn\u00e9 obaly. Rozdrvte ich priamo na list, aby ste zabr\u00e1nili vyliahnutiu potomstva.<\/p>\n\n\n\n
Neemov\u00fd olej: Skuto\u010dn\u00fd tip od zasv\u00e4ten\u00fdch. Ak rastliny postriekate zriedenou zmesou neemov\u00e9ho oleja a vody, larvy po\u010das k\u0155menia prehltn\u00fa \u00fa\u010dinn\u00fa l\u00e1tku. Zastav\u00ed sa ich v\u00fdvoj a zabr\u00e1ni sa im v rozmno\u017eovan\u00ed. Pre v\u010dely je \u00faplne ne\u0161kodn\u00fd.<\/p>\n\n\n\n
Chrenov\u00fd v\u00fdvar: Chrob\u00e1ky zemiakov\u00e9 nen\u00e1vidia \u0161tip\u013eav\u00fd z\u00e1pach chrenu. Z listov a kore\u0148ov si m\u00f4\u017eete pripravi\u0165 odvar a pravidelne n\u00edm postrekova\u0165 rastliny zemiakov.<\/p>\n\n\n\n
Dobr\u00ed susedia: V bezprostrednej bl\u00edzkosti alebo priamo medzi riadky zemiakov vysa\u010fte chren, rascu, koriander alebo m\u00e4tu pieporn\u00fa.<\/p>\n\n\n\n
Kvetinov\u00e1 bari\u00e9ra: V\u00f4ne necht\u00edka lek\u00e1rskeho a fac\u00e9lie s\u00fa tie\u017e mimoriadne odpudzuj\u00face pre zemiakov\u00e9 chrob\u00e1ky z Colorada.<\/p>\n\n\n\n
Jemn\u00fd kamenn\u00fd prach je skvelou, \u010disto mechanickou obranou, ktor\u00e1 chrob\u00e1kom s\u0165a\u017euje \u017eivot.<\/p>\n\n\n\n
Ako to funguje: Vlhk\u00e9 listy zemiakov (napr. r\u00e1no, ke\u010f je na nich e\u0161te rosa) popr\u00e1\u0161te tenkou vrstvou kamenn\u00e9ho prachu.<\/p>\n\n\n\n
\u00da\u010dinok: Chrob\u00e1ky a larvy str\u00e1caj\u00fa chu\u0165 do jedla, preto\u017ee prach im otupuje \u00fastne \u00fastrojenstvo a listy sa st\u00e1vaj\u00fa nejedl\u00fdmi. Okrem toho prach posil\u0148uje rastlinu d\u00f4le\u017eit\u00fdmi miner\u00e1lmi.<\/p>\n\n\n\n
Najlep\u0161\u00ed boj proti chrob\u00e1kovi je ten, s ktor\u00fdm nemus\u00edte bojova\u0165.<\/p>\n\n\n\n
Striedanie plod\u00edn je nevyhnutn\u00e9: Nikdy nesadzujte zemiaky (a in\u00e9 \u013eu\u013ekovce, ako s\u00fa paradajky) na to ist\u00e9 miesto dva roky po sebe. Chrob\u00e1ky prezimuj\u00fa v p\u00f4de a na jar sa jednoducho plazia nahor. Ak tam zrazu rastie hrach alebo \u0161al\u00e1t, hladuj\u00fa alebo musia pr\u00e1cne migrova\u0165 inde.<\/p>\n\n\n\n
Pou\u017eite sie\u0165ku proti hmyzu s jemn\u00fdmi okami: Zakrytie z\u00e1honov jemnou sie\u0165kou ihne\u010f po v\u00fdsadbe zabr\u00e1ni priletel\u00fdm chrob\u00e1kom v kladen\u00ed vaj\u00ed\u010dok na listy.<\/p>\n\n\n\n
\u010eal\u0161\u00ed tip pre milovn\u00edkov pr\u00edrody: Podporte u\u017eito\u010dn\u00fd hmyz vo va\u0161ej z\u00e1hrade! Bystr\u00fdky, ropuchy, lienky a vt\u00e1ky miluj\u00fa po\u017eieranie vaj\u00ed\u010dok a mal\u00fdch lariev zemiakovej chrob\u00e1ky. Pr\u00edrodn\u00e1 z\u00e1hrada s divok\u00fdmi z\u00e1kutiami je v tomto smere mimoriadne n\u00e1pomocn\u00e1.<\/p>\n","protected":false},"excerpt":{"rendered":"
