1. Zviratidzo

Chirwere chemashizha akatyoka chinokuvadza muromo kana kumucheto kwemashizha efodya.Maronda acho haana kurongeka muchimiro, shava, akasanganiswa nemakwapa machena asina kujairika, zvichiita kuti mashizha akatyoka matipi uye kumucheto kwemashizha.Muchikamu chekupedzisira, mavara madiki madiki akapararira pachirwere chechirwere, ndiko kuti, ascus yepathogen, uye inopindirana grey-white mheni-yakafanana mavara akafa anowanzoonekwa pamucheto wetsinga pakati pemashizha., Makwapa ane maburi asina kujairika.

2. Nzira dzekudzivirira

(1) Kana mapedza kukohwa, bvisai marara nemashizha akadonha mumunda mopisa nenguva.Tendeukirai ivhu nenguva kuti mufushire masara echirimwa ane chirwere akapararira mumunda mukatikati mevhu, dyarai zvine mutsindo, uye muwedzere fetereza yephosphorus ne potassium kusimudzira kukura kwembesa yefodya uye kuwedzera kurwisa zvirwere.

(2) Kana chirwere chikaonekwa mumunda, isai mishonga kudzivirira nekudzora munda wose nenguva.Mukubatana nekudzivirira uye kutonga kwezvimwe zvirwere, zvinotevera zvinogona kushandiswa:
