S-abscisic acid ine physiological mhedzisiro yakadai sekukonzera bud dormancy, kudonha kwemashizha uye kuvharira kukura kwesero, uye inozivikanwawo se "dormant hormone".

Yakawanikwa makore akapoteredza 1960 uye yakatumidzwa zvisizvo nekuti ine hukama ne kudonha kwemashizha emiti. Zvisinei, zvino yava kuzivikanwa kuti kudonha kwemashizha emiti nemichero kunokonzerwa ne ethylene.

Trinexapac-ethyl ndeye cyclohexanedione chirimwa chekukura regulator, gibberellins biosynthesis inhibitor, iyo inodzora kukura kwakasimba kwezvirimwa nekudzikisa zvirimo zvegibberellins. Trinexapac-ethyl inogona kukurumidza kubatwa uye inotungamirirwa nemashizha emiti uye mashizha, uye inobata basa rinopesana nekugara nekuderedza kureba kwemiti, kuwedzera simba retsinde, kukurudzira kuwedzera kwemidzi yechipiri, nekugadzira midzi yakanyatsogadziriswa.

Paclobutrazol mumiriri wekurima anogona kunetesa mukana wekukura kwezvirimwa. Inogona kutorwa nemidzi yezvirimwa nemashizha, kugadzirisa kugoverwa kwekudya kwechirimwa, kuderedza kukura, kudzivirira kukura kwepamusoro uye kurebesa dzinde, uye kupfupisa nhambwe yepakati. Panguva imwecheteyo, inosimudzira kusiyanisa kwemaruva, inowedzera huwandu hwemaruva emaruva, inowedzera chiyero chekuisa michero, inomhanyisa kupatsanurwa kwesero.

Iko kusanganiswa kwezvinomera zvinokura zvigadziriso uye fungicides zvinoenderana nemaitiro ekuita kwevamiririri, systemic conductivity, kuwirirana kwezvinhu zvekutonga, uye kana kupesana kuchaitika mushure mekusanganiswa. Mune zvimwe zviitiko, sekuzadzisa chinangwa chekudzivirira chirwere kana kuwedzera kudzivirira kwechirimwa, kukurudzira kukura kwechirimwa kana kurima mbesa dzakasimba.
