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.

Naphthalene acetic acid (NAA) is an auxin plant regulator. Inopinda mumuviri wechirimwa kuburikidza nemashizha, nyoro epidermis uye mbeu, uye inotakurwa kune zvikamu zvine simba rekukura (nzvimbo dzekukura, nhengo dzechidiki, maruva kana michero) nekuyerera kwezvokudya, zvinonyanya kukurudzira kukura kwetipi yemidzi (rooting powder) , kukonzera maruva, kudzivirira maruva nemichero inowira, kuumba michero isina mhodzi, kukurudzira kukura kwekutanga, kuwedzera kugadzirwa, etc. Inogonawo kuwedzera kukwanisa kwechirimwa kudzivisa kusanaya kwemvura, kutonhora, zvirwere, munyu uye alkali, uye mhepo inopisa yakaoma.
