Paclobutrazol ke ea li-azole limela tse laolang kholo ea limela, kaha ke biosynthetic inhibitors ea endogenous gibberellin. E na le litlamorao tsa ho sitisa kholo ea semela le ho khutsufatsa molumo. Mohlala, ho sebelisoa raeseng ho ka ntlafatsa ts'ebetso ea indole acetic acid oxidase, ho fokotsa boemo ba IAA ea tlhaho lipeong tsa raese, ho laola haholo sekhahla sa kholo ea lipeo tsa raese, ho khothaletsa lekhasi, ho etsa hore makhasi a be botala bo lefifi, tsamaiso ea metso e ntlafalitsoe, fokotsa sebaka sa bolulo le ho eketsa palo ea tlhahiso. Sekhahla sa taolo ka kakaretso se fihla ho 30%; sekhahla sa khothaletso ea lekhasi ke 50% ho isa ho 100%, 'me sekhahla sa keketseho ea tlhahiso ke 35%. Ho sebelisoa perekisi, pere, citrus, liapole le lifate tse ling tsa litholoana li ka sebelisoa ho khutsufatsa sefate. Geranium, poinsettia le lihlahla tse ling tsa mekhabiso, ha li phekoloa ka paclobutrazol, mofuta oa semela oa tsona o lokisoe, o fane ka boleng bo phahameng ba mekhabiso. Ho lengoa ha meroho ea sethopo joalo ka tamati le peto ho fana ka phello e matla ea sethopo.
Ho lema raese ea morao-rao ho ka matlafatsa peo, nakong ea lekhasi le le leng / pelo e le 'ngoe, ho omisa metsi a lipeo tšimong le ho sebelisa 100 ~ 300mg/L ea tharollo ea PPA bakeng sa ho fafatsa ka mokhoa o ts'oanang ka 15kg/100m.2. Laola kholo e feteletseng ea mochini o fetisetsa lipeo tsa raese. Kenya 150 kg ea 100 mg/L tharollo ea paclobutrazol bakeng sa ho inela 100kg ea peo ea raese bakeng sa 36h. Etsa kopo ea ho mela le ho jala ka lilemo tsa 35d le ho laola bolelele ba sethopo bo sa feteng 25cm. Ha e sebelisoa bakeng sa taolo ea lekala le tšireletso ea litholoana tsa sefate sa litholoana, hangata e lokela ho etsoa qetellong ea hoetla kapa selemo ka sefate se seng le se seng sa litholoana se tlas'a ente ea 500 mL ea 300mg / L paclobutrazol tharollo ea lithethefatsi, kapa ho nosetsoa ka mokhoa o tšoanang hammoho le 5. ~ 10cm sebaka sa bokaholimo ba mobu ho potoloha radius ea 1/2 ea moqhaka. Kenya 15% phofo ea metsi 98g/100m2kapa joalo. Sebelisa 100 m2paclobutrazol e nang le motsoako o sebetsang oa 1.2 ~ 1.8 g/100m2, ho khona ho khutsufatsa mateano a motheo a koro ea mariha le ho matlafatsa kutu.
Paclobutrazol e boetse e na le phello khahlanong le ho phatloha ha raese, k'hothone e khubelu ea rot, cereal smut, koro le mafome a lijalo tse ling hammoho le powdery hlobo, joalo-joalo E ka boela ea sebelisoa bakeng sa li-preservatives tsa litholoana. Ho feta moo, ka tekanyo e itseng, e boetse e na le phello ea thibelo khahlanong le mofoka o le mong, oa dicotyledonous.
Paclobutrazol ke molaoli o mocha oa kholo ea limela, o khona ho thibela ho thehoa ha lihlahisoa tsa gibberellin, ho fokotsa karohano ea lisele tsa semela le ho lelefatsa. E ka monngoa habonolo ke metso, likutu le makhasi 'me ea tsamaisoa ka xylem ea semela ka phello ea bactericidal. E na le ts'ebetso e pharaletseng ea limela tsa Gramineae, e khona ho etsa hore kutu ea semela e be mahlaka a makhutšoane, ho fokotsa bolulo le ho eketsa chai.
Ke buka e ncha, e sebetsang hantle haholo, taolo ea kholo ea semela e nang le chefo e tlase e nang le phello e pharalletseng ea bactericidal.
