Anthrax ndi matenda oyamba ndi mafangasi akamabzala phwetekere, zomwe zimawononga kwambiri. Ngati sichiyendetsedwa munthawi yake, imayambitsa kufa kwa tomato. Choncho, alimi onse ayenera kusamala kuchokera mmera, kuthirira, ndiye kupopera mbewu mankhwalawa mpaka fruiting nthawi.
Matenda a Anthrax amawononga kwambiri zipatso zomwe zakhwima, ndipo mbali iliyonse ya chipatso imatha kutenga kachilombo, nthawi zambiri mbali yapakati ya mchiuno imakhudzidwa kwambiri. Chipatso chodwala chimayamba kuoneka chonyowa ndikuzimiririka mawanga ang'onoang'ono, pang'onopang'ono kukula mpaka mawanga ozungulira kapena amorphous, okhala ndi mainchesi 1-1.5. Pali ma whorls okhazikika ndipo tinthu takuda timakula. Pankhani ya chinyezi chachikulu, mawanga apinki amamera pambuyo pake, ndipo mawanga a matendawa nthawi zambiri amawoneka ngati akusweka ngati nyenyezi. Zikavuta kwambiri, zipatso zodwala zimatha kuwola ndikugwera m'munda. Zipatso zambiri zopanda matenda pambuyo pa matenda zimatha kuwonetsa zizindikiro motsatizana panthawi yosungira, zoyendetsa ndi zogulitsa pambuyo pokolola, zomwe zimapangitsa kuti zipatso zowola ziwonjezeke.
Kuwongolera zaulimi
Limbikitsani kasamalidwe ka kulima ndi kuwongolera matenda:
1.Yeretsani m'munda mutakolola ndikuwononga matupi odwala ndi olumala.
2.Mutembenuzire nthaka mozama, ikani feteleza wokwanira wapamwamba kwambiri wa organic osakaniza ndi kukonzekera kumtunda, ndi kubzala m'malire ndi dzenje lakuya.
3.Tomato ndi mbewu yomwe imakula nthawi yayitali. Iyenera kuyang'aniridwa mosamala. Iyenera kudulira, nthambi ndi kumanga mipesa munthawi yake. Kupalira kuyenera kuchitika pafupipafupi kuti muchepetse mpweya wabwino komanso kuchepetsa chinyezi. Zipatso zimayenera kukolola munthawi yake panthawi yakucha kuti zokolola ziwonjezeke. Zipatso zodwala ziyenera kuchotsedwa m'munda ndikuwonongeka munthawi yake.
