Paradi\u017enik pri tem ni izjema. Najbolj pogoste bolezni paradi\u017enika so nekatere glivne bolezni in pomanjkanje kalcija.<\/p>\n

Glivne bolezni paradi\u017enika<\/h2>\n

Krompirjeva plesen<\/h3>\n

Krompirjevo plesen<\/a> povzro\u010da gliva Phytophthora infestans<\/em>. Bolezen prepoznamo po \u010drne\u010dih konicah listov. Listi za\u010dnejo nato gniti, hitro uvenijo in porjavijo. Med vla\u017enim vremenom lahko ob temnih pegah opazimo ne\u017eno belo glivno rast. Rjava podro\u010dja se lahko pojavijo tudi na steblih in na zelenih plodovih.
\nOku\u017eene rastline izkopljite iz grede in jih zakopljite vsaj 45 cm globoko, odlo\u017eite med biolo\u0161ke odpadke ali pa se\u017egite.
\nNajbolj\u0161i na\u010din za\u0161\u010dite je redno kolobarjenje<\/a>.<\/p>\n

\u017dametna pegavost paradi\u017enika<\/h3>\n

\u017dametno pegavost paradi\u017enika povzro\u010da gliva Cladosporium fulvum<\/em>. Pojavlja se v rastlinjakih in plastenjakih, kjer je navadno visoka zra\u010dna vlaga. Bolezen prepoznamo po rumenih \u017eametnih pegah, ki se pojavijo na zgornji strani listov. Pege so na spodnji strani zelenkasto-sive barve.
\nNajenostavneje boste bolezen prepre\u010dili z ustreznim prezra\u010devanjem, ki bo zni\u017ealo zra\u010dno vlago. Hkrati poskrbite tudi, da bo zrak okrog rastlin lepo kro\u017eil. V ta namen odstranjujte zalistnike in po\u010dasi propadajo\u010de stare liste.<\/p>\n

\u010crna pegavost paradi\u017enika<\/h3>\n

\u010crno pegavost paradi\u017enika povzro\u010data glivi Alternaria tomatophila<\/em>\u00a0in A. porri f.sp. solani<\/em>. Odgovarja jima de\u017eevno vreme in nekoliko vi\u0161je temperature med 20 in 30\u00b0C. Prezimita na rastlinskih ostankih na tleh, iz katerih se potem s sporami raz\u0161irita med rastlinami, ki jih oku\u017eita preko ran, listnih re\u017e, ali celo neposredno preko povr\u0161ine lista.
\nBolezen lahko prepoznamo po \u010drnih pegah, ki se pojavijo na listih, steblih in plodovih. Navadno so kroglaste oblike in imajo koncentri\u010dne kroge, ki jim dajejo videz tar\u010de.
\nPred boleznijo se zavarujemo predvsem s kolobarjenjem<\/a> in sajenjem sadik v zadostnem razmaku, ki dovoljujejo kro\u017eenje zraka med rastlinami.<\/p>\n

Pomanjkanje kalcija<\/h2>\n

Ob pomanjkanju kalcija lahko pri paradi\u017eniku pride do gnitja na dnu plodu (nasprotni konec od peclja). \u010ceprav je to posledica pomanjkanja kalcija pa nikakor ne pomeni, da je kalcija v tleh premalo. V resnici je to zgolj posledica su\u0161e (oz. neenakomerne oskrbe z vodo) ali prekomernega gnojenja z du\u0161ikom. Podobno lahko do tega pride tudi pri previsokih temperaturah. Do pomanjkanja pride, ker rastlina ne more dovolj hitro na\u010drpati dovolj kalcija, ne ker bi ga bilo premalo v tleh.
\nZa prepre\u010devanje je najbolje poskrbeti, da bodo rastline vedno ustrezno zalite in da ne pretiravate z gnojili – predvsem z du\u0161ikom, ki vzpodbuja rast nadzemnega dela rastline. Foliarno \u0161kropljenje s kalcijem navadno ni u\u010dinkovito, saj se kalcij te\u017eko privzame preko listov in prenese v plodove. Dodatno pa lahko du\u0161ik v teh pripravkih (pogosto gre za kalcijev nitrat) vzpodbuja razrast poganjkov in tako poslab\u0161a stanje.<\/p>\n","protected":false},"excerpt":{"rendered":"
