Mtundu wa Agrochemical: Wowongolera Kukula kwa Zomera
Njira Yogwirira Ntchito: Imalepheretsa gibberellin biosynthesis mwa kuletsa kutembenuka kwa ent-kaurene kukhala ent-kaurenoic acid, ndikuletsa biosynthesis ya sterol mwa kuletsa demethylation; motero amalepheretsa kugawanika kwa maselo.
Kupanga: Paclobutrazol 15%WP, 25%SC, 30%SC, 5%EC

Kugwiritsa ntchito
Paclobutrazol ndi azole zomera kukula owongolera, kukhala biosynthetic zoletsa wa amkati gibberellin. Zimakhala ndi zotsatira zolepheretsa kukula kwa zomera ndikufupikitsa phula. Mwachitsanzo, kugwiritsidwa ntchito mu mpunga kumatha kupititsa patsogolo ntchito ya indole acetic acid oxidase, kuchepetsa mlingo wa IAA wamkati mu mbande za mpunga, kuwongolera kwambiri kukula kwa mbande za mpunga, kulimbikitsa tsamba, kupangitsa masamba kukhala obiriwira, mizu imapangidwa, kuchepetsa malo ogona ndikuwonjezera kuchuluka kwa kupanga. Mlingo wamba wowongolera ndi mpaka 30%; Kukwezeleza masamba ndi 50% mpaka 100%, ndipo kuchuluka kwa kupanga ndi 35%. Kugwiritsidwa ntchito mu pichesi, peyala, citrus, maapulo ndi mitengo ina yazipatso kungagwiritsidwe ntchito kufupikitsa mtengo. Geranium, poinsettia ndi zitsamba zokongola, zikathandizidwa ndi paclobutrazol, mtundu wawo wa mbewu umasinthidwa, ndikupatsanso kukongola kwakukulu. Kulima wowonjezera kutentha masamba monga tomato ndi kugwiriridwa kumapereka amphamvu mmera kwenikweni.
Kulima mpunga mochedwa kumatha kulimbitsa mbande, pa tsamba limodzi/mtima umodzi, kuyanika madzi a mbande m’munda ndikuthira 100 ~ 300mg/L wa PPA solution popopera mbewu mofanana pa 15kg/100m.2. Yang'anirani kukula kwakukulu kwa makina oyika mbande za mpunga. Ikani 150 kg ya 100 mg/L ya paclobutrazol poviika 100kg ya mbeu ya mpunga kwa 36h. Ikani kameredwe ndi kubzala ndi msinkhu wa 35d ndikuwongolera kutalika kwa mbande kusapitirire 25cm. Mukagwiritsidwa ntchito ngati nthambi yoyang'anira ndi kuteteza zipatso za mtengo wa zipatso, ziyenera kuchitidwa kumapeto kwa autumn kapena masika ndi mtengo uliwonse wa zipatso womwe umaperekedwa ku jekeseni wa 500 mL wa 300mg/L paclobutrazol mankhwala, kapena kuthirira yunifolomu pamodzi ndi 5. ~ 10cm malo a dothi kuzungulira 1/2 korona radius. Ikani 15% wettability ufa 98g/100m2kapena choncho. Ikani 100 m2paclobutrazol ndi yogwira pophika 1.2 ~ 1.8 g/100m2, kutha kufupikitsa mphambano yoyambira ya tirigu yozizira ndikulimbitsa tsinde.
Paclobutrazol imakhudzanso kuphulika kwa mpunga, zowola zofiira za thonje, phala, tirigu ndi dzimbiri la mbewu zina komanso powdery mildew, ndi zina zotero. Ikhoza kugwiritsidwanso ntchito posungira zipatso. Kuphatikiza apo, mkati mwa kuchuluka kwake, imakhalanso ndi mphamvu yoletsa namsongole wina, dicotyledonous.
Paclobutrazol ndi chowongolera chakukula kwa zomera, chomwe chimatha kuletsa mapangidwe a gibberellin, kuchepetsa kugawanika kwa maselo a zomera ndi kutalika. Imatha kuyamwa mosavuta ndi mizu, zimayambira ndi masamba ndikuyendetsedwa kudzera mu xylem ya mmera ndi bactericidal effect. Lili ndi ntchito yochuluka pa zomera za Gramineae, zomwe zimatha kupanga tsinde la zomera kukhala mapesi aafupi, kuchepetsa malo ogona komanso kuonjezera zokolola.
Ndi buku, dzuwa, otsika kawopsedwe zomera kukula wowongolera ndi yotakata sipekitiramu bactericidal kwenikweni.
