Ak nechcete, aby sa va\u0161a jesenn\u00e1 \u00faroda zmenila na zbyto\u010dn\u00fa kopu mul\u010da, spo\u013eahnite sa na tieto \u0161tyri overen\u00e9 a \u00fa\u010dinn\u00e9 met\u00f3dy.<\/p>\n\n\n\n
Agrotechnick\u00e1 met\u00f3da: V\u00e1pnenie a intenz\u00edvne obr\u00e1banie p\u00f4dy
Dr\u00f4tovce sa dar\u00ed v kysl\u00fdch, \u0165a\u017ek\u00fdch a zhutnen\u00fdch p\u00f4dach, ak\u00e9 sa \u010dasto nach\u00e1dzaj\u00fa na b\u00fdval\u00fdch tr\u00e1vnat\u00fdch porastoch.<\/p>\n\n\n\n

Dom\u00e1ce pasce: N\u00e1vnada na zemiaky<\/p>\n\n\n\n
T\u00e1to met\u00f3da si vy\u017eaduje ur\u010dit\u00fa n\u00e1mahu, ale je vynikaj\u00faca pre men\u0161ie z\u00e1hrady a vyv\u00fd\u0161en\u00e9 z\u00e1hony, kde nechcete pou\u017e\u00edva\u0165 komer\u010dn\u00e9 produkty.<\/p>\n\n\n\n
Ako vyrobi\u0165 pascu: Rozre\u017ete ve\u013ek\u00fd, zdrav\u00fd zemiak (alebo mrkvu) na polovicu. Do ka\u017edej polovice zapichnite dreven\u00fa \u0161pajd\u013eu ako rukov\u00e4\u0165 a zna\u010dku.<\/p>\n\n\n\n
Aplik\u00e1cia: Zakopte polovice zemiakov asi 5\u201310 cm hlboko do p\u00f4dy (rezanou stranou nadol) v oblastiach, kde pl\u00e1nujete sadi\u0165 zemiaky alebo ste ich u\u017e sadili.<\/p>\n\n\n\n
Zber: Ka\u017ed\u00e9 2 a\u017e 3 dni vytiahnite pascu za \u0161pajd\u013eu, pozbierajte larvy zakopan\u00e9 v n\u00e1vnade (a zlikvidujte ich) a pascu znova zakopte.<\/p>\n\n\n\n
Na z\u00e1ver tip: Dr\u00f4tovce \u017eij\u00fa v p\u00f4de 3 a\u017e 5 rokov, k\u00fdm sa z nich vyvin\u00fa chrob\u00e1ky. \u00daspech preto z\u00e1vis\u00ed od kombin\u00e1cie a opakovania t\u00fdchto met\u00f3d.
