1. I-Paclobutrazol ingeyabalawuli bokukhula kwezitshalo ze-azole, okuyi-biosynthetic inhibitors ye-gibberellin engapheli.Inemiphumela yokuvimbela ukukhula kwezitshalo kanye nokwenza mfushane iphimbo.Isibonelo, ukusetshenziswa kwerayisi kungathuthukisa umsebenzi we-indole acetic acid oxidase, kunciphise izinga le-IAA engapheli ezithonjeni zelayisi, ukulawula ngokuphawulekayo izinga lokukhula phezulu kwezithombo zelayisi, kukhuthaze amaqabunga, kwenze amaqabunga abe luhlaza mnyama, uhlelo lwempande luthuthukisiwe, lunciphisa indawo yokuhlala futhi lwandise inani lokukhiqiza.Izinga lokulawula elijwayelekile lifika ku-30%;izinga lokukhushulwa kweqabunga lingama-50% kuya ku-100%, kanti izinga lokukhuphuka komkhiqizo lingama-35%.Ukusetshenziswa kwepentshisi, i-pear, i-citrus, ama-apula nezinye izihlahla zezithelo kungasetshenziswa ukufinyeza isihlahla.I-Geranium, i-poinsettia nezinye izihlahla zokuhlobisa, lapho ziphathwa nge-paclobutrazol, uhlobo lwazo lwesitshalo lulungiswe, lunikeze inani eliphakeme lokuhlobisa.Ukutshalwa kwemifino ebamba ukushisa okufana notamatisi nokudlwengula kunikeza umphumela oqinile wezithombo.
2. Ukutshalwa kwerayisi sekwephuzile kungaqinisa isithombo, ngesikhathi seqabunga elilodwa/inhliziyo eyodwa, komise amanzi ezithombo ensimini bese kugcotshwa isixazululo sePPA esingu-100~300mg/L sokufafaza okufanayo ngo-15kg/100m2.Lawula ukukhula ngokweqile komshini wokufakelwa izithombo zelayisi.Faka i-150 kg ye-100 mg/L ye-paclobutrazol isisombululo sokucwilisa u-100kg wembewu yerayisi amahora angu-36.Gcoba ukuhluma nokuhlwanyela ngeminyaka engama-35d yezithombo futhi ulawule ubude besithombo bungabi ngaphezu kwama-25cm.Uma isetshenziselwa ukulawulwa kwegatsha nokuvikela izithelo zesihlahla sezithelo, kufanele kwenziwe ngokujwayelekile ngasekupheleni kwekwindla noma entwasahlobo lapho isihlahla ngasinye sesithelo singaphansi kokujova ama-500 mL we-300mg/L yesisombululo sesidakamizwa se-paclobutrazol, noma ngaphansi kokunisela okufanayo kanye no-5. ~10cm indawo yenhlabathi ezungeze irediyasi yomqhele engu-1/2.Faka impushana emanzi engu-15% engu-98g/100m2 noma ngaphezulu.Faka i-paclobutrazol engu-100 m2 ngesithako esisebenzayo esingu-1.2~1.8 g/100m2, ukwazi ukufinyeza ukuphambana kwesisekelo sikakolweni wasebusika futhi uqinise isiqu.
3. I-Paclobutrazol iphinde ibe nomthelela ekuqhumeni kwerayisi, ukubola okubomvu kwekotini, i-cereal smut, ukolweni nokugqwala kwezinye izitshalo kanye ne-powdery mildew, njll. Ingasetshenziselwa futhi izinto ezivimbela izithelo.Ngaphezu kwalokho, phakathi kwenani elithile, liphinde libe nomthelela wokuvinjelwa kokhula olulodwa, lwe-dicotyledonous.
4. I-Paclobutrazol iyisilawuli sokukhula kwezitshalo inoveli, ekwazi ukuvimbela ukwakheka kwe-gibberellin derivatives, ukunciphisa ukuhlukaniswa kwamaseli esitshalo kanye nokwelula.Ingamuncwa kalula yizimpande, iziqu namaqabunga futhi iqhutshwe nge-xylem yesitshalo ngomphumela we-bactericidal.Inomsebenzi omningi ezitshalweni ze-Gramineae, ikwazi ukwenza iziqu zezitshalo zibe yizinhlanga ezimfushane, zinciphise indawo yokuhlala futhi zandise isivuno.
5. Kuyinoveli, ukusebenza kahle okuphezulu, isilawuli sokukhula kwesitshalo esinobuthi obuphansi esinomphumela obanzi we-bactericidal.
6. Inani elingaguquki lokusetshenziswa kwezinto zokusetshenziswa: I-Pinacolone: 930kg/t, 1,2,4-triazole 540kg/t, chlorobenzyl chloride 960kg/t.
