Anthrax chirwere chefungi chakajairika mukudyara kwematomatisi, izvo zvinokuvadza zvakanyanya. Kana ikasadzorwa nenguva, inotungamira kufa kwemadomasi. Naizvozvo, varimi vese vanofanirwa kutora matanho ekudzivirira kubva pakudyara, kudiridza, vobva vapfapfaidza kusvika panguva ye fruiting.
Chigwadara chinonyanya kukuvadza michero inenge yakura, uye chero chikamu chemuchero chinogona kutapukirwa, kazhinji chikamu chechiuno chepakati ndicho chinokanganisa. Chibereko chine chirwere chinotanga kuoneka chinyoro uye chakadzima tumakwapa tudiki, zvishoma nezvishoma chichiwedzera kuita denderedzwa kana amorphous chirwere makwapa, ane dhayamita 1 ~ 1.5 cm. Kune concentric whorls uye zvitema zvitema zvinokura. Panyaya yekunyorova kwepamusoro, mavara anonamira epingi anokura mune inotevera nhanho, uye makwapa echirwere anowanzo kuoneka nyeredzi. Kana yakakomba, muchero une chirwere unogona kuora uye kuwira mumunda. Zvibereko zvakawanda zvisina zvirwere mushure mehutachiwana zvinogona kuratidza zviratidzo zvakatevedzana panguva yekuchengetedza, kutakura uye kutengesa nguva mushure mekukohwa, zvichiita kuti nhamba inowedzera yezvibereko zvakaora.
Kudzora kwekurima
Simbisa manejimendi ekurima nekudzivirira zvirwere:
1.Chenesa gadheni mushure mekukohwa uye paradza miviri inorwara uye yakaremara.
2.Dzvanyai pamusoro pevhu, shandisai yakakwana yepamusoro-soro organic base fertilizer pamwe chete nekugadzirira ivhu, uye kudyara mumuganhu wakakwirira uye gomba rakadzika.
3.Tomato chirimwa chine nguva yakareba yekukura. Inofanira kunyatsotarisirwa. Inofanira kuchekerera, davi uye kusunga mizambiringa panguva yakakodzera. Kusakura kunofanira kuitwa nguva nenguva kuitira kuti munda upinde mhepo nekuderedza mwando. Muchero unofanirwa kukohwewa nenguva panguva yekuibva kuti uvandudze kunaka kwegoho. Muchero une chirwere unofanirwa kutorwa kunze kwemunda uye kuparadzwa nenguva.
