Utshani besihlabathi buyisitshalo “sesitikha” esibukeka njengotshani.Ngokuvamile ihlasela utshani obuncane, ikakhulukazi eminyakeni eyomile.Ngakho-ke, ukulawulwa okungcono kakhulu kwalolu khula utshani obukhulu futhi obunempilo.Kodwa-ke, uma utshani bakho buncane kakhulu kule ntwasahlobo futhi isihlabathi sotshani sangonyaka odlule siyinkinga, sebenzisa umuthi obulala ukhula ngaphambi kokuvela kwe-sand bur.Kodwa-ke, akuwona wonke ama-herbicides angaphambi kokuhluma asebenzayo.Imikhiqizo emithathu engasiza ekunciphiseni ukusika utshani utshani, i-pendimethalin ne-propylenediamine.
I-Oryzalin ithengiswa ngaphansi kwegama lomkhiqizo we-Weed Impede.Ingasetshenziswa kubo bonke utshani benkathi efudumele kanye notshani obude be-fescue.Ngaphandle kwe-fescue nobunye utshani obude, akufanele busetshenziswe otshanini ngezikhathi ezipholile, njengeKentucky bluegrass.I-Oryzalin nayo ingathengiswa njengenhlanganisela yeGreen Light Amaze ne-benefin.Njengotshani bubodwa, bungasetshenziswa kubo bonke utshani benkathi efudumele kanye notshani obude be-fescue.Ngaphandle kwe-fescue nobunye utshani obude, akufanele busetshenziswe otshanini ngezikhathi ezipholile, njengeKentucky bluegrass.Uma isihlahla se-bauhinia sesiqhakaza ngokugcwele, sebenzisa imikhiqizo ye-Amaze noma ye-Oryzalin cishe ngomhlaka-15 Ephreli.
