Kusakanikirana kwa zowongolera zakukula kwa zomera ndi fungicides kumadalira momwe zimagwirira ntchito, machitidwe adongosolo, kukwanirana kwa zinthu zomwe zimayendetsedwa, komanso ngati kusagwirizana kudzachitika pambuyo posakanikirana. Nthawi zina, monga kukwaniritsa cholinga chopewera matenda kapena kukulitsa kukana matenda a mbewu, kulimbikitsa kukula kwa mbewu kapena kulima mbande zolimba.

Naphthalene acetic acid (NAA) ndi chowongolera chomera cha auxin. Imalowa m'thupi la chomera kudzera m'masamba, epidermis yanthete ndi njere, ndipo imatumizidwa kumadera omwe amakula mwamphamvu (malo okulirapo, ziwalo zazing'ono, maluwa kapena zipatso) ndikuyenda kwa michere, kulimbikitsa kwambiri kukula kwa mizu (poda ya mizu) , kuchititsa maluwa, kuteteza maluwa ndi zipatso kugwa, kupanga zipatso zopanda mbewu, kulimbikitsa kukhwima msanga, kuchulukitsa kupanga, ndi zina zotero. Zingathenso kuwonjezera mphamvu ya zomera kukana chilala, kuzizira, matenda, mchere ndi alkali, ndi mphepo yotentha yowuma.

Indole-3-butyric acid (IBA) ndi chowongolera kukula kwa mbewu chomwe chimatha kulimbikitsa kukula ndikukula kwa mbewu, kupangitsa kuti mbewuyo ikhale yobiriwira komanso yamphamvu, ndikuwongolera chitetezo cham'mera komanso kukana kupsinjika.

Brassinolide (BRs) ndiwowongolera bwino kukula kwa mbewu omwe amagwiritsidwa ntchito pochepetsa kuwonongeka kwa mankhwala ophera tizilombo. Brassinolide (BRs) imatha kuthandiza mbewu kuti ziyambirenso kukula bwino, kukonza bwino zinthu zaulimi ndikuwonjezera zokolola, makamaka pochepetsa kuwonongeka kwa herbicide. Ikhoza kufulumizitsa kaphatikizidwe ka amino acid m'thupi, kupanga ma amino acid omwe atayika chifukwa cha kuwonongeka kwa mankhwala ophera tizilombo, ndikukwaniritsa zosowa za kukula kwa mbewu, potero kuchepetsa kuwonongeka kwa mankhwala.
