Prohexadione ni ubwoko bushya bwo gukura kw'ibimera bya acide cyclohexane. Yateguwe ku bufatanye n’Ubuyapani Combination Chemical Industry Co., Ltd. na BASF yo mu Budage. Irabuza biosynthesis ya gibberelline mu bimera kandi ikora ibimera Ibigize gibberelline bigabanuka, bityo bikadindiza kandi bikagenzura imikurire y’ibimera. Ahanini ikoreshwa mubihingwa byibinyampeke, nk'ingano, sayiri, kurwanya umuceri, birashobora no gukoreshwa mubishyimbo, indabyo na nyakatsi kugirango bigenzure imikurire yabyo.

Gukemura (20 ℃): 174 mg / L mumazi yatoboye; methanol 1,11 mg / L, acetone 0.038 mg / L, n-hexane ＜ 0.003 mg / L, toluene 0.004 mg / L, Ethyl acetate ＜ 0.010 mg / L, iso Propanol 0,105 mg / L, dichloromethane 0.004 mg / L. Igihagararo: ubushyuhe buhamye bugera kuri 180 ℃; hydrolysis DT50 <5 d (pH = 4, 20 ℃), 21 d (pH7, 20 ℃), 89 d (pH9, 25 ℃); mumazi karemano, fotolisi yamazi DT50 ni 6.3 d, fotolisi DT50 mumazi yatoboye yari 2.7 d (29 ～ 34 ℃, 0.25W / m2).
Uburozi: Umuti wumwimerere wa prohexadione numuti wica udukoko twangiza. Umunwa ukabije LD50 (umugabo / igitsina gore) wimbeba ni> 5.000 mg / kg, acute percutaneous LD50 (umugabo / igitsina gore) yimbeba ni> 2000 mg / kg, naho umunwa ukabije LD50 yimbeba (umugabo / umugore) ni> 2000 mg / kg. Guhumeka uburozi LC50 (4 h, umugabo / umugore)> 4.21 mg / L. Muri icyo gihe, ifite uburozi buke ku bidukikije nk'inyoni, amafi, ibishishwa by'amazi, algae, inzuki, n'inzoka zo mu isi.
Uburyo bwibikorwa: Mu kubangamira synthesis ya gibberellic mu bimera, bigabanya ibirimo aside aside ya gibberellique mu bimera, igenzura imikurire y’amaguru, igatera imbere indabyo n'imbuto, ikongera umusaruro, igateza imbere imizi, ikarinda uturemangingo na selile ya organelle, kandi igateza imbere guhangana n’ibihingwa. Kugirango rero ubuze imikurire yibimera byo hejuru yikimera no guteza imbere imikurire.
2 Kwiyandikisha
Ubushakashatsi bwakozwe n’urusobe rw’amakuru y’udukoko twangiza udukoko mu Bushinwa, kugeza muri Mutarama 2022, mu gihugu cyanjye hamaze kwandikwa ibicuruzwa 11 bya calcium ya prohexadione, birimo imiti 3 ya tekiniki n’imyiteguro 8, nk'uko bigaragara mu mbonerahamwe ya 1.

3 Icyizere cy'isoko
Nkumucungamutungo wicyatsi kibisi, calcium ya prohexadione ni kimwe nogukuza ibimera bya paclobutrazol, niconazole na trinexapac-ethyl. Irabuza biosynthesis ya aside ya gibberellic mu bimera, ikagira uruhare mu bihingwa byangiza, Uruhare rwo kugenzura imikurire y’ibihingwa. Nyamara, prohexadione-calcium ntigisigara ku bimera, nta kwanduza ibidukikije, kandi ntigira ingaruka nke ku bihingwa byakurikiyeho no ku bimera bitagenewe. Birashobora kuvugwa ko ifite ibyifuzo byinshi byo gusaba.
