Thidiazuron (TDZ) ndi wowongolera kukula kwa mbewu za urea. Itha kugwiritsidwa ntchito pansi pamikhalidwe yayikulu ya thonje, kukonzedwa tomato, tsabola ndi mbewu zina. Ikamwedwa ndi masamba a zomera, imatha kulimbikitsa kudulidwa kwamasamba koyambirira, komwe kumapindulitsa pakukolola ndi makina. ; Imagwiritsidwa ntchito m'malo otsika kwambiri, imakhala ndi ntchito ya cytokinin ndipo imatha kugwiritsidwa ntchito mu maapulo, mapeyala, mapichesi, yamatcheri, mavwende, mavwende ndi mbewu zina kuti muwonjezere kuchuluka kwa zipatso, kulimbikitsa kukula kwa zipatso, ndikuwonjezera zokolola ndi zabwino.

Brassinolide (BR) ndi yosiyana ndi ena owongolera kukula kwa mbewu munjira yake imodzi yolunjika pakulimbikitsa zokolola komanso kukonza bwino. Mwachitsanzo, sikuti ili ndi ntchito zakuthupi za auxin ndi cytokinin, komanso imatha kuwonjezera photosynthesis ndikuwongolera kagayidwe kazakudya, kulimbikitsa kayendetsedwe kazakudya kuchokera kumitengo ndi masamba kupita kumbewu, kukonza kukana kwa mbewu kuzinthu zoyipa zakunja, ndi kulimbikitsa kukula kwa mbali zofooka za zomera. Chifukwa chake, ili ndi magwiritsidwe ambiri komanso magwiridwe antchito.

DA-6 (Diethyl aminoethyl hexanoate) ndi chowongolera chakukula kwa mbewu champhamvu chokhala ndi mawonekedwe otakata komanso opambana. Ikhoza kuonjezera ntchito ya zomera peroxidase ndi nitrate reductase, kuonjezera chlorophyll okhutira, kufulumizitsa photosynthesis, kulimbikitsa magawano ndi elongation wa zomera zomera, kulimbikitsa chitukuko cha kachitidwe mizu, ndi kulamulira moyenera zakudya m'thupi.

Ufa wa mizu ndi njira yoyendetsera kukula kwa zomera zomwe zimalimbikitsa kukula kwa mizu ya zomera.

Ntchito yake yaikulu ndikulimbikitsa mizu ya zomera, kufulumizitsa kukula kwa mizu ya zomera, ndikuthandizira kupirira kupsinjika kwa zomera. Pa nthawi yomweyo, ufa wa mizu umathandizanso poyambitsa nthaka, kusunga chinyezi cha nthaka, ndi kulimbikitsa kuyamwa kwa michere.
