Fusarium Uyafuna: ulawulo nokuthintela kunye nezifo

Nosipho kwezinto lokutyala iya kuthintela ithuba lokungena iintsholongwane ebhedini lembewu. ukumba Good umhlaba, kanzima, ukutshintshwa ujikelezo zeendawana kunye kweentsholongwane izixhobo kukhokelela ekubeni ithuba ukuhla ingenzeka kwezifo. Iintsholongwane ayiyo zikhule kakuhle kwi air lobushushu eliphezulu (malunga 28 ° C), ukufuma aphezulu kunye photoperiod elifutshane. Ngoko ke, kufuneka ukungena nokuphuma kakuhle zokugcina. Ukuze siphephe kuyimfuneko kanye ngeveki ukuya kuhlola iibhedi kunye nokuchonga izityalo abosulelekileyo. iisampulu zizifo zisusiwe kwaye zitshiswe. Iziphumo ezincumisayo obonisa pre-eziqhumayo umhlaba kunye kweentsholongwane wayo arhente ezikhethekileyo bemvelo ngokusekelwe abamelene ezinzwaneni. "Privekur" zingasetyenziswa ngamachiza.
