Ples\u0148ov\u00e9 ochorenia, najm\u00e4 plese\u0148 zemiakov\u00e1<\/strong> (Phytophthora infestans<\/em>), s\u00fa no\u010dnou morou ka\u017ed\u00e9ho pestovate\u013ea paradajok. Dok\u00e1\u017eu zni\u010di\u0165 cel\u00fa \u00farodu v priebehu nieko\u013ek\u00fdch dn\u00ed, najm\u00e4 ak je vlhk\u00e9 a tepl\u00e9 po\u010dasie.<\/p>\n\n\n\n

Tu je n\u00e1vod, ako nepriate\u013ea v\u010das rozpozna\u0165 a ak\u00e9 kroky podnikn\u00fa\u0165 sk\u00f4r, ne\u017e bude neskoro.<\/p>\n\n\n\n

\n\n\n\n

1. Ako rozpozna\u0165 plese\u0148 (Sympt\u00f3my)<\/h3>\n\n\n\n

Plese\u0148 sa \u0161\u00edri nen\u00e1padne, zvy\u010dajne od spodn\u00fdch listov smerom nahor. Sledujte tieto znaky:<\/p>\n\n\n\n

    \n
  • Listy:<\/strong> Na okrajoch sa objavuj\u00fa nejasn\u00e9, sivo-zelen\u00e9 alebo hnedast\u00e9 “vodnat\u00e9” \u0161kvrny. Za vlhka sa na spodnej strane listov m\u00f4\u017ee vytvori\u0165 jemn\u00fd biely povlak.<\/li>\n\n\n\n
  • Stonky:<\/strong> Objavuj\u00fa sa na nich tmavohned\u00e9 a\u017e \u010dierne f\u013eaky, ktor\u00e9 sa r\u00fdchlo roz\u0161iruj\u00fa. Ak plese\u0148 zasiahne hlavn\u00fa stonku, rastlina odumiera.<\/li>\n\n\n\n
  • Plody:<\/strong> Na paradajk\u00e1ch (aj zelen\u00fdch) vznikaj\u00fa tvrd\u00e9, vr\u00e1skav\u00e9, hned\u00e9 \u0161kvrny, ktor\u00e9 siahaj\u00fa hlboko do du\u017einy. Tak\u00e9to plody s\u00fa nejedl\u00e9.<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    2. Prevencia: Z\u00e1klad \u00faspechu<\/h3>\n\n\n\n

    Ke\u010f u\u017e plese\u0148 vypukne, je \u0165a\u017ek\u00e9 ju zastavi\u0165. Prevencia je preto 90 % \u00faspechu.<\/p>\n\n\n\n

      \n
    • Zalievanie ku kore\u0148om:<\/strong> Nikdy nepolievajte paradajky na listy! Vlhk\u00e9 listy s\u00fa pozv\u00e1nkou pre sp\u00f3ry plesn\u00ed.<\/li>\n\n\n\n
    • Vzdu\u0161nos\u0165 (Spon):<\/strong> Paradajky nesa\u010fte pr\u00edli\u0161 husto. Medzi rastlinami mus\u00ed pr\u00fadi\u0165 vzduch, aby listy po da\u017edi r\u00fdchlo oschli.<\/li>\n\n\n\n
    • Odstra\u0148ovanie spodn\u00fdch listov:<\/strong> Pravidelne vylamujte listy od zeme a\u017e po prv\u00fd strapec plodov. Listy by sa nemali dot\u00fdka\u0165 p\u00f4dy.<\/li>\n\n\n\n
    • Strecha nad hlavou:<\/strong> Ak pestujete paradajky vonku, jednoduch\u00fd pr\u00edstre\u0161ok, ktor\u00fd ich ochr\u00e1ni pred da\u017e\u010fom, je najlep\u0161ou ochranou.<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      3. Pr\u00edrodn\u00e9 postreky (Ke\u010f hroz\u00ed riziko)<\/h3>\n\n\n\n

      Ak predpove\u010f hl\u00e1si dlhotrvaj\u00face da\u017ede, aplikujte tieto dom\u00e1ce postreky ka\u017ed\u00fdch 7 \u2013 10 dn\u00ed:<\/p>\n\n\n\n

        \n
      • Mlie\u010dny postrek:<\/strong> Zmie\u0161ajte n\u00edzkotu\u010dn\u00e9 mlieko s vodou v pomere 1:5<\/strong>. Bielkoviny v mlieku vytv\u00e1raj\u00fa na listoch ochrann\u00fd film, na ktorom sa plesne \u0165a\u017e\u0161ie uchytia.<\/li>\n\n\n\n
      • S\u00f3da bikarb\u00f3na:<\/strong> Rozpustite 1 \u010dajov\u00fa ly\u017ei\u010dku s\u00f3dy v 1 litri vody<\/strong> a pridajte p\u00e1r kvapiek tekut\u00e9ho mydla (aby postrek dr\u017eal na listoch). S\u00f3da men\u00ed pH povrchu listov, \u010do plesniam nevyhovuje.<\/li>\n\n\n\n
      • Cesnakov\u00fd v\u00fdluh:<\/strong> 50 g rozpu\u010den\u00e9ho cesnaku zalejte 1 litrom vody, nechajte 24 hod\u00edn l\u00fahova\u0165 a po sceden\u00ed striekajte. Cesnak m\u00e1 siln\u00e9 fungic\u00eddne \u00fa\u010dinky.<\/li>\n<\/ul>\n\n\n\n
        \n\n\n\n

        4. \u010co robi\u0165, ak sa plese\u0148 u\u017e objavila?<\/h3>\n\n\n\n

        Ak n\u00e1jdete prv\u00fd napadnut\u00fd list, mus\u00edte kona\u0165 okam\u017eite:<\/p>\n\n\n\n

          \n
        1. Chirurgick\u00fd rez:<\/strong> Napadnut\u00e9 listy alebo plody ihne\u010f odtrhnite.<\/li>\n\n\n\n
        2. Likvid\u00e1cia:<\/strong> Listy nikdy ned\u00e1vajte do kompostu<\/strong>! Sp\u00f3ry v \u0148om pre\u017eij\u00fa. Najlep\u0161ie je ich sp\u00e1li\u0165 alebo vyhodi\u0165 do komun\u00e1lneho odpadu.<\/li>\n\n\n\n
        3. Dezinfekcia n\u00e1radia:<\/strong> Po kontakte s chorou rastlinou si umyte ruky a vydezinfikujte no\u017enice (alkoholom alebo octom), aby ste chorobu nepreniesli na zdrav\u00e9 kusy.<\/li>\n<\/ol>\n\n\n\n
          \n\n\n\n

          R\u00fdchly preh\u013ead ochrany:<\/h3>\n\n\n\n
          Faktor<\/strong><\/td>Ide\u00e1lny stav<\/strong><\/td><\/tr><\/thead>
          Z\u00e1lievka<\/strong><\/td>V\u00fdhradne ku kore\u0148om, r\u00e1no (aby sa vlhkos\u0165 cez de\u0148 odparila).<\/td><\/tr>

          \n

          Tip odborn\u00edka:<\/strong> Ak pestujete v sklen\u00edku, vetrajte non-stop. Vysok\u00e1 vlhkos\u0165 a stojat\u00fd vzduch v sklen\u00edku zabij\u00fa paradajky sk\u00f4r ako tie vonkaj\u0161ie na da\u017edi.<\/p>\n<\/blockquote>\n\n\n\n
