Oo, esi sifo sobuqili! Zingaphi iikhemikhali kunye neendlela abagadi begadi abangacingi ngazo, kwaye umbuzo uhlala uvulekile kulolu suku. Ingxaki kukuba ukukhusela kulula, kodwa kubalulekile ukuqonda imbangela ebalulekileyo kwaye uqale umsebenzi ukusuka ekuwa. Xa zonke iintshukumo zingenanto, umntu kufuneka asebenzise ukutshiza. Kwaye sele sele sele isele isigqibo sengozi ngokwayo, sinika ukhetho kumntu okanye kwintengiso. Ngokuchanekileyo, impendulo kumbuzo, nokuba kuyimfuneko ukupakisha utamatisi kwi-phytophthora, iya kuba yinkxaso, kodwa kuphela kufuneka kwenziwe ngokufanelekileyo. Zonke izityalo zasehlotyeni ziye zahlula zibe ziinkampu ezimbini ixesha elide: omnye ukhetha kuphela iindlela zokupheka zelizwe, ngelixa ezinye zikhetha iindlela zokusetyenziswa kweekhemikhali.
Ukukhuselwa kweetamatato kwizilwanyana zamachiza e-phytophthora
Makhe sijonge uluhlu lweendlela zokutyala ezidumileyo kunye nezihlandlo zokutyala:
- Enye yezindlela ezintle kakhulu ukupheka ityuwa. Kodwa iyafaneleka kuphela kwisigaba sokuqala. Ngokukhawuleza ukuba iziqhamo zokuqala eziphangiweyo ziphawulwe, kubalulekile ukuzisusa kunye namahlamvu ngexesha elifutshane. Emva koko kwibhakethi elitini lelitriki sibheka ingilazi yetyuwa. Lo ngumntu onobuhle kunabo bonke bendawo, kunokuba ungazifefa iitamatisi: ukwenza ifilimu okanye uthintela ityuwa kwi-phytophthora, ngaloo ndlela udala umqobo kwifungus.
- Isisombululo esithakazelisayo, kunokuba sifanele sitshatyathe iitamatisi kwi-greenhouse, kukunika igalikhi evela kwi-phytophthora. Kuvela ukuba i-fungus yakhe ayithandi. Oku kufezekileyo kwihlobo ehlobo kunye nemvula eninzi kunye nomswakama ophakamileyo. Umsebenzi wakho ukuwaphula iintloko zegalikhi kwaye udibanise kunye ne-potassium permanganate: malunga nekomityi yehafu yale nto ifakwe kwibhakethi yamanzi. Kuze kube mahlanu kwixesha nganye kwiiveki ezimbini, izinga elilinganiselwayo.
- Ngokuqhelekileyo kwintlu yemimiselo yokukhusela izityalo zamatamatisi ziqukethe i-serum kunye ne-iodine evela kwi-phytophthora. I-whey whey izalwe kwisiqingatha ngamanzi kwaye ukususela ekuqaleni kwexesha elifudumele kakhulu, malunga nokusukela ngoJulayi, unokusingatha ngokukhuselekileyo ukutyala. Ukuba i-serum ayifumananga, itshintshelwa ngobisi kwaye ihlaziywe ngamanzi, idibanisa i-drops 15 ye-iodine. Yonke yenzelwe ibhakethi yamanzi.
I-Phytophthora kwiitamatati kunye nokunyangwa ngamalungiselelo amakhemikhali
Ngaphambi kokutshiza utamatisi kunye nokulungiselela amashishini kwi-phytophthora, kubalulekile ukukhumbula enye inyaniso elula. Yonke into kweli hlabathi iguqule kwaye i-fungus ayikho. Ukuba ukhetha isigqibo ngokugqithiseleyo, kuya kufuneka uthenge ngokukhawuleza iintlobo ezininzi, njengoko iifungus ichitshiyelwe kwaye kwixesha lesibini iikhemikhali ezithengiweyo kwangaphambili zingenamandla.
Ngokuqhelekileyo, onke amalungiselelo ekhemikhali kunyango lwe-phytophthora yahlula ibe yimveliso ye-biological kunye ne-fungicides yamatamatato. Iqela lokuqala libhekwa njengendlela ekhuselekileyo. Into ebalulekileyo yintoni: uhlanyela iyeza kwaye ibhaktheriya kuyo iqala ukuphindaphinda ngokukhawuleza, ukuya kwindawo echaphazelekayo bayichitha iifungus.
Ngoko ke, kuyafaneleka ukuba sicinge ukuba kulungile kangakanani ukulwa ne-phytophthora kunye ne-fungicides kwiitamatati. I-Phytophthora fungus iyanqabile kwaye akuyiyo into yokuba iya kuba yingozi, kodwa impilo yethu iya kunyikima nakwezinye izilwanyana ezinkulu. Phakathi kwazo zidla ngokuza amagama kaKvardis, Hom, uDitan kunye neBravo. Kodwa ukusebenzisa i- Bordeaux liquid okanye i-chloride yobhedu ayizange ikhanselwe ngumntu.
Yintoni ekufanelekile ukuyisebenzisa, uyigqibo. Kodwa kuhlale kulunge ukukhusela ingxaki kunokufuna isisombululo sayo kwisigaba esele siyingozi ekuvuneni. Kwaye ngaphambi kokufafaza utamatisi kwi-phytophthors kunye neekhemikhali, kuyafaneleka ukuba uzame kwizigaba zokuqala ukuba ube nobumnene kunye nengozi kubantu.
