Defoliant nigenzura ryikura rishobora guteza imbere ibihingwa kumera amababi mugihe cyizuba, kugabanya igihe cyikura ryibihingwa, kunoza imikorere ya fotosintezez yibihingwa, no kongera igihingwa kurwanya imihangayiko nubukonje. Uburyo bwibikorwa bya defoliants nuguhindura urwego rwimisemburo ya endogenous, gusaza amababi, no guteza imbere kumeneka. Ku bimera bimaze igihe kinini mubushyuhe buke, gukoresha neza defoliants nabyo bishobora guteza imbere imikurire niterambere.

Imiterere yumubiri na chimique ya forchlorfenuron (KT-30). Forchlorfenuron ni kimwe mu bintu by'ingenzi bigize umutobe wa cocout. Umuti wumwimerere ni ifu yera ikomeye, idashonga mumazi, kandi irashobora gushonga byoroshye mumashanyarazi nka acetone na Ethanol

Nkumuyobozi ushinzwe imikurire yikimera, 2,4-D irashobora guteza imbere igabana, kurinda indabyo nimbuto kugwa, kongera igipimo cyimbuto, guteza imbere kwaguka kwimbuto, kuzamura ubwiza bwimbuto, kongera umusaruro, no gutuma ibihingwa bikura hakiri kare kandi bikongerera igihe cyo kubaho kwa imbuto.
