Prohexadione calcium wani ƙananan guba ne, mai saura mara amfani koren girma mai sarrafa shukar shuka wanda aka yadu ana amfani dashi a cikin amfanin gona mai ɗimbin yawa (kamar shinkafa, alkama, da sha'ir) don haɓaka juriya na masauki da samar da fa'idodi da yawa gami da haɓaka yawan amfanin ƙasa da ingantaccen inganci.
Tsarin aiki da halaye na Prohexadione calcium:
1. Hana haɗin gibberellin: Ta hanyar hana biosynthesis na gibberellins (musamman GA₁) a cikin tsire-tsire, yana sarrafa girma mai yawa, yana gajarta internodes, yana ƙarfafa mai tushe, don haka yana inganta juriya na masauki.
2. Haɓaka haɓakar haifuwa: Yayin da yake hana ci gaban ciyayi, baya hana haɗin gibberellin a cikin hatsi da 'ya'yan itace, wanda ke da fa'ida don haɓaka ƙimar saitin iri, nauyin hatsi dubu, da yawan amfanin ƙasa.
3. Haɓaka juriya na damuwa: Yana inganta juriya ga amfanin gona ga cututtuka (kamar shinkafa ƙarya smut da ganye), fari, ƙananan zafin jiki, da lalacewar ciyawa.
4. Abokan muhalli: Shortan rabin rayuwa (<24 hours a cikin ƙasa), metabolites nasa sune carbon dioxide da ruwa, kuma ba shi da tasiri akan amfanin gona na gaba.
