(2) Emva kokuba esi sifo senzeka kumagqabi erayisi, kuya kuvela amachokoza amancinane aluhlaza mnyama emagqabini, aze ngokuthe ngcembe ande abe ngamachokoza.Umbindi wamachokoza ungwevu, imiphetho imdaka, kwaye kukho ihalo emthubi ephaphathekileyo ngaphandle.Kwimeko yokufuma, kukho iileya zokungunda ezingwevu ngasemva kwamagqabi.
2. Indlela yokuthintela kunye nokunyanga
Ngexesha lokuqala losulelo, Ukuxuba i-Tricyclazole 450-500g exutywe ne-450L yamanzi ngehektare nganye, ukutshiza.

(1) Isifo serice smut ngokuqhelekileyo sibakho kuphela kwasekuqaleni, nto leyo eya kwenzakalisa inxalenye yengqolowa.Kwingqolowa echaphazelekayo, iibhloko ze-mycelium ziya kubumba kwaye zandise ngokuthe ngcembe, kwaye i-glue yangaphakathi nangaphandle iya kuhlukana, ibonise iibhloko eziphuzi eziphuzi, ezibizwa ngokuba yi-sporophyte.
(2) kwaye emva koko isongelwe kumacala omabini angaphakathi kunye nangaphandle, umbala omnyama oluhlaza, kwinqanaba lokuqala, umphandle uhlanganiswe ngomqolo wefilimu, kwaye emva koko uqhekeke kwaye usasazeke umgubo omnyama oluhlaza.
2. Indlela yokuthintela kunye nokunyanga
Ingasebenzisa i-5% ye-Jinggangmycin SL 1-1.5L yokuxuba ne-450L yamanzi ngehektare nganye.

1 amagqabi, awasasazeki kwisityalo sonke.
(2) Kwinqanaba leetiolated amagqabi amhlophe, kwinqanaba lokuqala lesi sifo, amagqabi anesigulo awasayi kufa, kodwa angathi acandwe ngokubanzi okanye acandwe kancinci, abe namachokoza eklorotiki angaqhelekanga kuwo, aze ke akhule abe ngamabala atyheli okanye amakhulu.
2. Indlela yokuthintela kunye nokunyanga
(1) Inokusebenzisa iMatrine 0.5%SL,ukuxuba i-0.8-1L kunye namanzi angama-450L, ukutshiza.
