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.

Indole-3-butyric acid (IBA) inogadzirisa kukura kwechirimwa iyo inogona kukurudzira kukura kwechirimwa uye kusimukira, kuita kuti zvidyarwa zvive zvakasvibirira uye zvakasimba, uye kuvandudza kusadzivirirwa kwechirimwa uye kusagadzikana kusagadzikana.

Brassinolide (BRs) isimba rinoshanda rekukura kwechirimwa rinoshandiswa kuderedza kukuvadzwa kwezvipembenene. Brassinolide (BRs) inogona kubatsira zvirimwa kuti zvitangezve kukura, nekukurumidza kuvandudza mhando yezvigadzirwa zvekurima uye kuwedzera goho, kunyanya mukuderedza kukuvadzwa kwemishonga yesora. Inogona kukurumidzira kuumbwa kwemaamino acids mumuviri, kugadzira maamino acids akarasika nekuda kwekukuvadzwa kwemushonga wezvipembenene, uye kusangana nezvinodiwa zvekukura kwechirimwa, nekudaro kuderedza kukuvadzwa kwemushonga.
