Thepa ea Physicochemical le Khethollo ea Tlhaho ea Brassinolide

【Lebitso le Tloaelehileng】Brassinolide

【Foromo ea molek'hule】C28H46O6

【Boima ba Molek'hule】 480.68

【Thepa ea Physicochemical】 phofo e tšoeu ea kristale; ntlha ea ho qhibiliha 256-258 ° C; ho qhibiliha ka metsing 5 mg/kg; Monyetla o bonolo ho qhibiliha ka har'a metsoako ea tlhaho e kang methanol, ethanol le acetone.

【Toxicity】 Chefo e tlase. Acute oral LD50 ho likhoto> 2000 mg/kg; acute oral LD50 ho litoeba>1000 mg/kg (tekanyo ea botekgeniki).

【Sehlopha】 Taolo ea kholo ea limela.

【Mekhabiso e Tloaelehileng】95% kereiti ea tekheniki; 0.01% emulsifiable concentrate (EC); 0.04% le 0.1% ea tharollo ea metsi (AS); 0.2% phofo e qhibilihang (SP).

【Boitsebiso】

(1) Boitsebiso ba 'Mele (Sensory): Phofo e metsi e bonahala e le phofo e tšoeu e tiileng; emulsifiable concentrate le aqueous solution li hlaha e le mokelikeli o ts'oanang, o bonaletsang.

Setšoantšo sa moralo oa mokhoa oa ho sekamela lekhasi la raese bakeng sa boitsebahatso ba Brassinolide

(2) Boitsebiso ba Likokoana-hloko: Mokhoa oa ho sekamela lekhasi la raese.
