Enye yezinto ze-phenomena ukuthi amabala amancane aphuzi avela emaqabungeni, bese esoma futhi afe. Enye yezizathu zalesi simo ukuthi utshani bungenwe yigciwane futhi buhlushwa igciwane liyawuthathwa, olungenzeka futhi luhambisane notshani obuningi. Lapho lesi sifo sikhula, sizobhubhisa lonke oluhlaza okwesikhashana.

2.symmots ngemuva kokutheleleka ngegciwane
Ngemuva kokutheleleka, izindawo ezinamanzi angu-1 mm zizovela emaqabungeni, okunzima ukuthola iso elinqunu. Amabala azokhulisa kancane kancane futhi ajike okuluhlaza okotshani ku-blow-brown noma amhlophe kuze kube sekufeni. Amabala azokwanda futhi aqede umngcele kuze kube yilapho lonke iqabunga libulawa. Lapho imvelo ezungezile inomswakama, kuzokhiqizwa ama-bacterial pus ezindaweni, ezingaphazamisa amanxeba ezitshalo ukuze alekele noma akwenze izifo. Isifo se-Bacterial Will kwi-Bencrass ekhazimulayo okokuqala sivela njengomuntu obomvu wemali noma onombala wethusiAma-Patches, kulandelwa ukufa kwenani elikhulu lezitshalo ezizungezile, kubhubhisa lonke oluhlaza okwesikhashana ngesikhathi esifushane.

Lapho lesi sifo senzeka okokuqala, amaqabunga avela oluhlaza okwesibhakabhaka futhi abuna, futhi amaqabunga ancipha futhi kancane kancane avule onsundu obomvu noma onsomi, ekugcineni, eholela ekufeni kwamaqabunga. Iziqeshana ezinobukhulu bemali zizovela otshanini obulabe, futhi ngokushesha indawo enkulu yotshani izobuna futhi ife.

4. Izimo zokwehla kwe-bacterial wilt

QAPHELA: I-Bentgrass Toronto (C-is), iNimisilla, izinhlobo zezinhlobonhlobo ze-Bermudagrass Tifgreen zitholwa kulesi sifo.

2Ukulimala okulinganiselayo, futhi ugweme ukumbozwa kwesihlabathi esivamile.
Lapho lesi sifo senzeka, ukwelashwa ngezidakamizwa okusebenzayo nokunamandla kufanele kwamukelwe
