I-Cyperus rotundus ithanda ukukhula emhlabathini ovulekile, futhi ukwenzeka kwenhlabathi enesihlabathi kubi kakhulu.Ikakhulukazi ezindaweni zommbila nezomoba, iCyperus rotundus kunzima kakhulu ukuyilawula.

Ngokuvamile iba umphakathi omncane owodwa noma oxutshwe nezinye izitshalo ukuze uqhudelane ngenkazimulo, amanzi nomanyolo, okubangela ukuba ezinye izitshalo zikhule kabi.Iphinde ibe nezilwane ezifuywayo ezinomhlane omhlophe, izimbungulu ezimnyama ezinukayo, amabhungane okusansimbi nezinye izinambuzane.Ingolunye lokhula oluyingozi kakhulu emhlabeni wonke.

Ngenxa yezimpande ezikhethekile ze-tuber ye-Cyperus rotundus, isihluthulelo sokukhipha ukhula ukubulala izimpande.

Izindlela zokulawula amakhemikhali:

1. Ummbila

I-Benazone - Isetshenziswa lapho ummbila 4-6 ushiya, lo mkhiqizo usebenza kahle lapho izinga lokushisa liphezulu, kodwa umphumela umpofu uma izinga lokushisa liphansi.Isetshenziswa ngokuqapha emvuleni kakhulu noma eminyakeni eyomile.I-Benzopine iphephile esitshalweni esilandelayo.

I-Chlorpyrisulfuron - Lesi sibulala-khula ngokuvamile sisetshenziswa ngemva kwamaqabunga ama-3-5 ommbila.Inomthelela omuhle otshanini obunamaqabunga abanzi kanye ne-sedge, futhi ingenasici, kodwa ijubane lotshani obufayo lihamba kancane.Ngokuvamile kuthatha isikhathi esingaphezu kwesigamu senyanga ukufa ngokuphelele otshanini.Akunconyiwe futhi kusebenza ngempumelelo i-Fast dimethyl tetrachloride nokunye ukusetshenziswa okuxubile, ukuze kungakhiqizi ukuphikisa.

I-Glyphosate - Ngemva kwamaqabunga angu-10 ommbila, lapho ungaphezu kwesigamu semitha, ungasebenzisa i-glyphosate (i-glyphosate ngaphandle kwezinye izithako) ukufutha ukhula ngamanzi, unake isifutho esiqondisayo, ungafafazi kummbila, isimiso sokukhula sebenzisa ukhula Kanye nomehluko wendawo phakathi kwezitshalo.

2. Insimu yezithelo

Ama-Orchards ngokuvamile ancoma ukusetshenziswa kwe-dimethyl•metazone, glyphosate, ne-glufosinate ngokufafaza okuqondisayo, futhi qaphela ukuthi ungafafazi ezihlahleni zezithelo.

Uma uthi eyakho ingxenye eyodwa kwezintathu yehektare ingambiwa ngesandla, ungayisusa ngokuphelele iRadix Aconiti eminyakeni emi-2 kuya kwemi-3.
