Ngenxa yotshintsho lwemozulu eqhubekayo, imozulu kunye namaxesha uye angabakho kangako, ihlala ikhokelela kwilahleko yezityalo. Iinkcukacha-manani zibonisa ukuba i-60% ukuya kwi-80% yelahleko yesivuno ye-crop ibangelwa uxinzelelo lwe-abiotic; Izivuno zesityalo ziphezulu kwimozulu elungileyo kwaye iphantsi kwiminyaka yemozulu embi. I-BIO

I-Indolecetitic acid (iaa), inyathelo lemizimba lezemizimba: Ithintela isityalo, igcina i-apilication, ikhuthaze i-stoptropispy, ikhuthaze i-stoptropispy, iphakamise.Mane: ikhuthaza ukucocwa kwamasiko; ivelisa isiqhamo esingenasinuli; ukukhuthaza ukukhula kwezityalo kunye nokuzala, kuthintela intyatyambo kunye neziqhamo zihla, kwaye kunyusa isivuno; ukukhuthaza ukuhluma kwembewu; kwaye i-Indeds Capius kunye neMonoyitha kwinkcubeko yezicubu.

Amaziko okukhula okubuhlobo bokukhula okusingqongileyo ahlulwe ngokubanzi abe ziindidi ezimbini: 1. I-HOFO YEMOFA YOKUGQIBELA Emoyeni okanye i-analog yabo; 2. Imibutho ekhutshwe kwizinto zendalo okanye ifunyenwe ngokuvela kwe-rotial. Oku kuphembelelo ngokubanzi kwindalo kwaye kuthoba ityhefu esezantsi kwizinto ezingabalulekanga (ezinje ngeenyosi kunye neentaka).

Xa ujongana nemiceli mngeni yokukhula kwezityalo ekwindla yasekwindla nasebusika, sihlala sidibana nabo uMgaqo-nkqubo wokukhula kwetyala onjenge-brasigolide, i-DA-6, nesodium nitrophenola. Ngelixa bonke abameli bonke bakhuthaza ukukhula kwezityalo, iipropathi zabo kunye nemithamo enconyelwayo iyahluka. Abalawuli abahlukeneyo baneziphumo ezahlukeneyo zokukhuthaza kunye nemithamo. I-Brasigolide, i-DA-6, nesodium witrophenola malunga neempawu zazo kunye nokugxininiswa okufanelekileyo.
