enantiomeric separation of prothioconazole and prothioconazole‐desthio was performed on various chiralstationaryphases (CSPs) by high‐performance liquid chromatography (HPLC). It was found that polysaccharide CSPs showed better ability than brushing CSPs in enantiomeric separation. The successful chiral separation of prothioconazole could be achieved on self‐made Chiralcel OD, commercialized Chiralcel
Fungicidal mixtures comprising
a) a benzophenone of the formula I,
b) a carbamate of the formula II, and
c) an azole derivative of the formula III in a synergistically effective amount, and a method for controlling harmful fungi using mixtures of the compounds I, II and III are described. The active compounds of the formulae I, II and III are defined in the description.
the degradation rates of 10 mg/L (Rac)-/(S)-/(R)-prothioconazole by strain AJ-1 were 76.0 %, 100.0 % and 64.8 % within 6 d, respectively. The CS bond of prothioconazole was methylated to produce (S)-/(R)-prothioconazole-S-methyl by strain AJ-1, but the degradation rate of prothioconazole by strain AJ-1 with (S)-enantiomer was 2.54-fold of that with (R)-enantiomer. Moreover, the toxicity of (Rac)-pro
丙硫菌唑是一种应用广泛的手性三唑类杀菌剂,其残留污染近年来受到广泛关注。然而,关于丙硫菌唑对映体的微生物代谢过程知之甚少。在这项研究中,丙硫菌唑降解菌株Sphingomonas sp。AJ-1,从活性污泥中分离出来。菌株AJ-1降解丙硫菌唑的最适温度和pH分别为30℃和6.0,菌株AJ-1降解丙硫菌唑的速率与初始浓度呈负相关。当添加额外的碳源时,降解率为 10 mg/L ( Rac )-/( S )-/( RAJ-1 菌株的 )-丙硫菌唑在 6 d 内分别为 76.0%、100.0% 和 64.8%。菌株AJ-1将丙硫菌唑的CS键甲基化生成( S )-/( R ) -丙硫菌唑-S-甲基,但菌株AJ-1对丙硫菌唑的降解率为2.54- ( R )-对映异构体的倍数。此外,(Rac)-丙硫菌唑-S-甲基对Pseudokirchneriella subcapitata的毒性比( Rac ) -丙硫菌唑低5
