Kubalulekile ukunqanda ukwenzeka kwezifo kwaye kunqunyulwe iindlela zosulelo. Iindlela zokudluliselwa kwezifo ezixhaphake kakhulu kwiindawo zokugcina izityalo zibandakanya ukuhamba komoya, amanzi, izinto eziphilayo kunye nezinye izinto. Nangona kunjalo, iindlela zokudlulisela izifo ezahlukeneyo zahlukile. Abalimi bemifuno kufuneka baqulunqe amacebo afanelekileyo okuthintela nokulawula asekelwe kwiimpawu zosulelo lwezifo ezahlukeneyo.
Ukutshiza + umsi kunokuphelisa ukusasazeka kokuhamba komoya
Usasazo lwangoku lomoya yeyona ndlela iphambili yosulelo lwezifo ezininzi. Imbewu eveliswa ngumngundo incinci kwaye ilula, kwaye inokusasazeka ngokukhawuleza kwaye ikude ngemisinga yomoya, efana negrey mold, i-downy mildew, i-powdy mildew, njl. uthintelo kunye nonyango. Ukuthatha i-gray mold eqhelekileyo njengomzekelo, xa ukhusela kwaye uphatha esi sifo, akufanele sisebenzise ukutshiza kuphela, kodwa sidibanise kunye ne-fumigation yomsi ukubulala ibhaktheriya ye-pathogenic emiswe emoyeni.
Nciphisa ukudibana phakathi kwamanzi kunye ne-pathogens
Ngokuqhelekileyo, izifo ezifana neebhaktheriya, i-fungi, kunye ne-oomycetes zivame ukwenzeka phantsi kobushushu obuphezulu kunye neemeko zokufuma okuphezulu. Phakathi kwazo, izifo zengcambu (izifo zebhaktheriya) kunye nezifo ze-oomycete zisasazeka ngamanzi. Ezinye iintsholongwane zineflagella, yaye iioomycetes zinokuvelisa iindawo zogcino-zilwanyana, ezisasazwa ikakhulu ngumbethe ogqunywe kumphezulu wezityalo. Kwizifo ezisasazeka ngale ndlela, ukuba ufuna ukukhusela isifo ukuba singenzeki, kufuneka uqale uqinise ummiselo womswakama we-greenhouse.
Amanyathelo athile: Khetha ifilimu ye-shed high-high ukunciphisa ukuxinana kumphezulu wefilimu yokuchitha; gubungela umhlaba nge-mulch, i-straw, njl.; amanzi phantsi kwefilimu kunye nokubonelela ngokungena komoya okufanelekileyo kunye nokususwa komswakama. Iintsholongwane zezifo zeengcambu zisemhlabeni okanye kumphezulu womhlaba kwaye zinokusasazwa ngamanzi emva kokunkcenkceshela. Eyona nto iphambili yale ndlela yosulelo lwesifo kukuba iziko lesifo liyabonakala. Njengoko ukunkcenkceshela kuqhubeka, iibhaktheriya ze-pathogenic ziyaqhubeka zisasazeka kwaye zandisa indawo yokusuleleka. Ngoko ke, ziphephe izityalo ezigulayo xa unkcenkceshela.
Ngamafutshane, ukunqunyulwa kwendlela yokudlulisela kunokunciphisa iziganeko zemifuno yokulahla, kwaye kwangaxeshanye, ukukhusela nokulawula isifo ngamachiza aneempawu ngokwe-pathogen.
