Indlela yokuluhlaza yokuvelisa imifuno kunye nezinye izityalo ayiqinisekisi ukuba awuyi kujongana nezifo nezidalwa ezinambuzane. Ngoko ukuthintela i-phytophthora ekuqaleni kuya kuba yindlela efanelekileyo kakhulu kwiindawo zokugcina izityalo zokukhusela izityalo zentamatyambo kwilahleko. Ukuqinisekisa ukuba zonke iinzame aziyize, kufuneka uziqhelise ngendlela yokwenzeka kwile ngxaki uze ufumane iindlela zokukhusela le ntlekele yendalo.
Isizathu se phytophthora kwiitamatati
Ngoko, ingxaki ikhona kwiingongoma ezibini ezibalulekileyo. Okokuqala, kubalulekile ukuqonda apho ingcambu ibangelwa khona, ngokuqhelekileyo - i-spores spores. I-fungus iyayibekezelela ngokugqithiseleyo iqhwa lasebusika kwii-tuber tubers. Ngokufudumala i-mycelium ngokuphepha iqala uhambo lwayo. Uyifaka kwi-greenhouse kwizixhobo zemiyezo, nomhlaba osulelekileyo, kwaye i-fungus ivakale kakhulu kwimbewu ye-Solanaceae. Ngoko, kwisangqa somntu ohambahambayo, sinokuzibona zombini umhlaba kunye nezinto zokutyala.
Ngokuqhubekayo malunga nokusetyenziswa kosulelo. Kutheni i sityalo singaguli, okanye singagqirha ngokugula, kwinqanaba lokukhula okukhulayo? Ewe, kuba phantse bonke banezifo ezikhuselekileyo kwezi zifo. Kodwa ngokuqala kokuvuthwa, yonke imikhosi iqhuma ngokuchanekileyo ekubunjweni komntwana, ngoko akunakwenzeka ukuhlangabezana nale fungus. Ngokuqhelekileyo, iingxaki ezinjalo zivela ngeentlobo, apho iziganeko zibonisa ukukhula komlinganiselo kunye nokuvunwa okuphezulu.
Unokukhusela njani utamatisi kwi-phytophthora?
Kalokunje ukuba siqonde indlela yokusuleleka kwiitamatati, sinokuyilungisa indlela efanelekileyo yokulungisa i-phytophthora. Akukho nto yokuyilungisa apha ayimfuneko kwaye yanele ukuba iqhubeke nje kuzo zonke ezi ngasentla. Ngoko ke, yintoni enokuyisebenzisa utamatati ukukhusela i-phytophthora kwaye ungenza ntoni apha:
- ukuba ukuqala kokutshabalalisa ininzi kwenzeka phakathi kwehlobo, ngoko kunengqiqo ukukhetha iintlobo zokuqala, oku kuya kusindisa iitamatayi kwi-phytophthora, kuba siya kuvuna isityalo phambi kokusabalalisa kwayo;
- abafuni iintlobo zakudala, ngoko ke sikhetha kuphela ezo zichasene nesi sifo;
- ekukhangekeni kwendlela yokunyanga utamatisi, khawuqwalasele indlela esele iqinisekiswe ixesha elide kwaye libonakaliswe ukukhusela i-phytophthora kunye ne-potassium permanganate kwiimbewu (ngendlela, imbewu yakhe isetyenziswe kuphela ukuba ineminyaka emithathu);
- Ukukhusela utamatisi kwi-phytophthora kunokubakho unyango kunye neendlela ezinzulu, oko kukuthi, ukutshatyalaliswa kwazo zonke iigwegwe kunye nezimilo zezityalo, ukususa uhla oluphezulu lomhlaba okungenani u-5 cm.
Ukuba unqwenela ukukhusela utamatisi kwi-phytophthora, kufuneka uhlaziye njani ukutshabalalisa i-greenhouse emva kokuvuna iikhemikhali okanye i-sulfur beads, yinto efanelekileyo yokweba umhlaba. Ngenxa yoko, ukuthintela i-phytophthora kwiitamatati kuncitshiswa ekusebenziseni izinto zokutyala kwi-greenhouse, ukukhetha kwayo ngokucophelela, ukusetyenziswa kwe-greenhouse kunye nomhlaba.
