Umgomo wokulawula ukukhula we-chlorrequat chloride we-chloride usekelwe ikakhulu endimeni yawo ekuvikeleni ukuhlanganiswa kwe-gibbellin kanye nokulawula ibhalansi yama-hormone ezitshalweni. Ngokukhawulela ukugcwala kwamaseli kunokuba uhlukanise, ama-internode wesitshalo afinyeziwe futhi iziqu zizinqeke, ngaleyo ndlela zithuthukise ukumelana nokulala.

Umsebenzi wePaclobutrazol: I-PACLOBUTRAZOL ingabambezela ngempumelelo ukukhula kwezitshalo, inxeka i-internation ye-internode, ukuthuthukisa ukumelana kwezitshalo.

I-Sodium nitrophenolates ingumbhali wokukhula wesitshalo ophansi. Akunangozi emzimbeni womuntu lapho isetshenziswa ekugxilweni okubekiwe. Ibonwa emhlabeni wonke ngokuphepha kwayo. Ingasetshenziswa ezinhlobonhlobo zezicelo, njengezitshalo zemali, izilimo zokudla, izithelo, imifino, njll.

I-Sodium nitrophenolates kanye ne-Urea kuxutshwe njengomanyolo wesisekelo, okungukuthi, ngaphambi kokuhlwanyela noma ukutshala. Isilinganiso sokuxuba yile: 1.8% sodium nitrophetolate (20-30 amagremu), amakhilogremu angama-45 e-urea. Kule ngxube, i-acre eyodwa ngokuvamile yanele. Ngaphezu kwalokho, inani le-urea lingashintshwa ngendlela efanele, ikakhulukazi ngokuya ngezimo zenhlabathi.
